Two Ways to Find a Tool

At the Alder Quay workshop, residents share tools for small building projects. For years, each cupboard carried a short code, such as R4, that also appeared beside its contents in a paper inventory ledger. Regular volunteers learned the codes, but first-time visitors often asked which cupboard held a particular tool. A code could identify a location precisely without telling a newcomer what was stored there.

The coordinator considered replacing the codes with descriptions. However, volunteers still used the codes when checking tools against the ledger. Replacing them would require changing those records as well. Instead, the workshop kept each code and added a large, plain-language description below it. The revised labels made the contents more apparent: visitors could see what a cupboard held before opening its door.

To observe the change, the coordinator recorded requests for directions during two Saturday sessions of equal length. At the first session, before the new labels appeared, visitors made fourteen requests. At the second, they made six. Both sessions had the same number of visitors, but a different pair of volunteers staffed the second session. Two tools were still returned to the wrong cupboards during that session.

The workshop also kept dated return forms. Each form recorded a tool's code, its assigned cupboard, and the cupboard where it was found. These records helped volunteers distinguish a misplaced tool from an inaccurate inventory entry.

The coordinator described the first results as encouraging rather than conclusive. Different volunteers might have offered help before visitors asked for it. The workshop would keep the revised labels while collecting records from more sessions. A useful label, the coordinator explained, must help someone locate an object while still connecting that object to a dependable record.

What can be inferred about a regular volunteer who knows the cupboard codes but has not yet read the added descriptions?

The ledger uses the cupboard codes, and those codes remain on the revised labels. A volunteer who already knows them can therefore continue matching records to cupboards. The passage does not establish how that volunteer's need for directions compares with every newcomer's.

The volunteer can still match a ledger code to its cupboard.: Correct. Retaining the codes preserves the connection that the volunteer already uses.

The volunteer must learn new codes before checking the ledger.: This overlooks that the codes were retained rather than replaced.

The volunteer can use the descriptions to correct every ledger entry.: This assumes the volunteer has read the descriptions and that those descriptions resolve all record errors.

The volunteer will need fewer directions than every first-time visitor.: This turns general familiarity with codes into an unsupported comparison with every newcomer.

A Caption in Pencil

Imani was helping arrange an exhibition in the town of Fern Hollow when she unfolded a faded banner. Its painted border showed golden stalks tied with blue ribbon. She immediately pictured an autumn harvest celebration and drafted a caption to match. The exhibition opened in two days, and having one more label finished felt like progress.

Before printing the caption, she showed it to Tomas, another volunteer. He asked what connected the banner to a harvest. Imani pointed to the stalks. Tomas nodded, then placed a penciled note beside the cloth. It had been stored in the same box and read, 'For the hall, July.' He did not offer a replacement explanation. Instead, he suggested checking the records that accompanied the collection.

They found a dated sketch whose border matched the banner, including an uneven cluster of stalks in one corner. On the back, the artist had written that the design was for the reopening of the town hall. A program from the same July listed a reopening ceremony and described a banner over the entrance. An accession ledger separately recorded who had donated each object, but Imani had not yet examined the banner's entry.

Imani crossed out the harvest caption. For a moment, the empty label seemed like a setback. Then she wrote a new caption connecting the banner to the reopening and naming the sketch and program as evidence. She left the donor line blank until she could consult the ledger.

As they packed away the unused labels, Tomas handed her a photograph with no date. Imani began to reach for a pen, then selected a pencil. On a temporary card, she wrote what the photograph showed and added a question about when it had been taken. The unfinished part of the description no longer felt like a failure.

Which summary best captures the passage as a whole?

Imani first assumes the banner is connected to a harvest, then revises that account using the sketch and program. Her response to the undated photograph shows a broader change: she is willing to state what is known while leaving an unanswered question. The exhibition is not postponed, and the donor's identity remains unverified.

A volunteer prepares a harvest exhibition, locates a missing donor record, and uses a photograph to complete the final label.: This preserves the initial mistaken harvest interpretation and treats the unresolved donor and photograph details as completed work.

Two volunteers debate a banner's purpose, settle on Tomas's preferred explanation, and finish the remaining labels together.: This substitutes Tomas's authority for the records and treats labels that remain incomplete as finished work.

A volunteer searches for a banner's artist, finds an incomplete sketch, and postpones the exhibition until its records are finished.: This changes the search's purpose and adds a postponement that never occurs.

A volunteer revises an assumed history after checking records and learns to acknowledge what she has not yet verified.: Correct. This includes both the correction of the caption and the change reflected in Imani's final action.

On a temporary card, she wrote what the photograph showed and added a question about when it had been taken. The unfinished part of the description no longer felt like a failure.

Which source should Imani consult to complete the donor line on the banner's caption?

The passage identifies the accession ledger as the record of who donated each object. Its banner entry directly addresses the missing donor line. A record identifying the banner's maker or original purpose would answer a different question because the maker and donor need not be the same person.

The program describing the banner at the town hall's reopening ceremony: This confuses a record of the banner's use at an event with a record of its later donation.

The penciled note found beside the banner in its storage box: This assumes that a note naming a place and month also identifies a donor.

The accession ledger entry recording who donated the banner: Correct. The ledger is explicitly described as recording each object's donor.

The artist's inscription explaining the purpose of the matching sketch: This treats information about the artist and design purpose as though it identifies the person who donated the object.

Question 11Reading · Craft and structure · Identify the author's purpose (inform, persuade, entertain, explain) Incorrect

Open the Rehearsal Door

The Bellmere Playhouse should try opening three rehearsals to a small audience this winter. A rehearsal would not replace a finished performance. It would let visitors watch scenes being revised and hear actors explain why a line or movement changes. This limited experiment could offer a different way to take part in local theater without committing the playhouse to a permanent program.

At a recent performance, eighteen of twenty-four people who returned a survey said they would attend an open rehearsal. That response is worth noticing, but it came from people already attending the theater. It does not tell us how many residents who rarely visit would come. One respondent called open rehearsals 'the most welcoming idea the playhouse has proposed.' That is an appealing endorsement, not a measurement of community demand.

There are practical limits. The rehearsal room has space for twenty visitors while leaving the actors' working area clear. The director has agreed to identify pauses when questions would be useful, rather than letting visitors interrupt a scene. Organizers estimate that one paid host per session would be the main additional expense. The board has not yet checked that estimate against the complete staffing schedule.

Some members worry that free rehearsals could reduce paid attendance. Others believe visitors would become more interested in buying tickets after meeting the actors. We should treat both predictions as questions to investigate. Registration records could show whether the pilot attracts newcomers, while later ticket purchases could help us understand what those visitors do next.

The board should authorize the three sessions, record attendance and actual staffing costs, and then reconsider the proposal. A small trial with clear limits is a better basis for that decision than either an enthusiastic survey response or an untested fear about ticket sales.

What is the author's primary purpose in this passage?

The opening recommends three open rehearsals, and the conclusion asks the board to authorize that trial. Details about surveys, staffing, and possible ticket effects support a proposal rather than report a completed program. The brief reference to actors revising scenes explains the proposed experience, not an acting technique.

To advocate testing open rehearsals in a limited trial: Correct. The passage recommends a trial and gives reasons for testing it within limits.

To explain how actors revise their stage movements: This mistakes one description of rehearsal activity for the purpose of the entire passage.

To predict that open rehearsals will increase ticket sales: The passage mentions this prediction only to say it should be tested, not to argue for it.

To encourage readers to buy tickets for winter shows: This confuses a possible future effect on ticket purchases with a direct sales appeal.

Question 28Reading · Integration of knowledge and ideas · Use evidence from the text to make predictions Incorrect

Listening Along the Canal

The town of Neralin has begun collecting descriptions of sounds along its old canal. The project is not a contest to identify the most birds or the quietest place. Its purpose is to build a record of what people hear at particular locations and times. A delivery bell, a rustling reed bed, and an engine passing under a bridge can all belong in the record.

Each volunteer visits an assigned point for ten minutes. Before listening, the volunteer records the date, starting time, and location code. During the visit, the volunteer notes each distinct sound and whether it is brief, repeated, or continuous. An uncertain sound receives a description such as “three short whistles” rather than a guessed source. Volunteers are asked to keep their observations separate from explanations they may later propose.

The project’s first report arranged observations by place and time. One canal bend had repeated whistles in both morning and afternoon visits. Another had engine noise during most afternoon visits but during few morning visits. These entries show when sounds were reported; they do not establish why the patterns occurred. A different number of volunteers visited the two locations, and no one counted the vehicles or animals present.

To make the record easier to compare, the organizers will assign the same number of visits to every location next month. They will also keep the listening periods equal in length. The original descriptions will remain available even when later information suggests a likely source. In this way, someone reading the record can distinguish what was heard from what was inferred. The organizers hope the collection will become useful to walkers, local artists, and anyone interested in how an ordinary place changes over the course of a day.

During a future visit, a volunteer hears repeated sounds resembling a small bell but cannot identify their source. Which entry is most consistent with the project’s method?

The method records an uncertain sound by describing it rather than by naming a guessed source, and keeps explanations separate from observations. 'Repeated bell-like ringing' describes the sound without claiming what made it. Naming a bell, a bicycle bell or a delivery bell would turn a resemblance into an identification.

“Delivery bell,” because that sound is named in the project’s introduction: This selects a mentioned example as the source without evidence connecting it to this sound.

“Repeated bell-like ringing,” with the source left unnamed: Correct. This describes what was heard and keeps the uncertain source out of the observation.

“Bicycle bell,” because the resemblance is enough to identify the source: This turns a resemblance into a confirmed identification.

“Bell,” because a short label is easier to compare across visits: This names a source, a bell, for a sound the volunteer could not identify.

Question 33Reading · Integration of knowledge and ideas · Compare ideas across two short texts: common ground Incorrect

Two Views of the Neighborhood Notice Board

Text A — Place the board at the market entrance The market entrance is the best place for the neighborhood notice board. Residents already pass that doorway when buying food, so a board there would fit into an existing routine. Moving it to the reading room might give people more space to study announcements, but it would also require a separate trip for many residents. The entrance can become crowded on Saturday mornings. A board mounted beside, rather than inside, the doorway could keep readers from blocking the line. I recommend trying that location for a month and noting how often people stop to read.

Text B — Place the board in the reading room The board should be inside the reading room, where visitors can stop without standing in a busy entrance. Detailed announcements are easier to read when people have time and space to compare them. The market location would probably reach more residents during their regular errands, but readers there may feel pressure to move quickly. The reading room is closed on Sunday, which limits access. We could extend its opening hours on one evening each week during a one-month trial and record how visitors use the board.

Which statement is true of both writers?

Text A concedes that the market entrance can become crowded on Saturday mornings, and Text B concedes that the reading room is closed on Sunday. Each writer therefore admits a drawback of the location they prefer, even though they disagree about which location is better.

The reading room is already open on Sunday and therefore needs no change in hours.: This reverses the explicit Sunday-closure limitation in Text B.

Detailed notices should be removed so people can read every announcement quickly.: This invents a proposal to remove detailed notices that neither writer makes.

Each writer admits a drawback of their preferred location while still recommending it.: Correct. Text A admits Saturday crowding at the entrance and Text B admits that the reading room is closed on Sunday, yet each writer still recommends that location.

The market entrance would keep residents from seeing the board during their regular errands.: This reverses both texts’ recognition that the market fits existing errands.

Question 47Mathematics · Numbers and algebra · Solve one-step and multi-step word problems Incorrect

A club receives 6 boxes containing 18 pencils each. After setting aside 17 pencils, members divide the remaining pencils into packets of 7. How many complete packets can they make?

The boxes contain 6 × 18 = 108 pencils. Setting aside 17 leaves 91, and 91 ÷ 7 = 13 complete packets. Dividing 108 by 7 without removing the reserved pencils would incorrectly suggest 15 complete packets.

11: Eleven packets use 77 pencils, leaving enough of the available 91 for two more packets.

13: Correct. The 91 available pencils fill 13 packets of 7.

15: This counts packets before setting aside the 17 pencils.

17: This adds the 17 set-aside pencils instead of subtracting them: 125 ÷ 7 gives 17 complete packets.

Question 48Mathematics · Numbers and algebra · Percent problems: percent of a number, percent change, discount, tax, tip Incorrect

A community class now has 108 participants after enrollment increased by 20%. How many participants were enrolled before the increase?

After a 20% increase, the new enrollment is 120% of the original, so the original number is 108 ÷ 1.20 = 90. Subtracting 20% of 108 uses the new enrollment as the base, whereas the increase was based on the original enrollment.

21.6: This is 20% of the new enrollment, not the original enrollment.

86.4: This subtracts 20% of 108 using the wrong base and gives a nonwhole participant count.

88: This subtracts 20 people rather than undoing a 20% increase.

90: Correct. Increasing 90 by 20% adds 18 and gives 108.

Question 56Mathematics · Numbers and algebra · Solve equations with one variable Incorrect

Solve 4(2x - 3) = 5x + 15 for x. Enter the value of x as a whole number.

Your answer: 10Correct answer: 9

Distribute 4 to obtain 8x - 12 = 5x + 15. Subtracting 5x and adding 12 gives 3x = 27, so x = 9. The 4 must multiply both terms inside the parentheses; leaving the -3 unchanged would produce an incorrect equation.

Question 70Mathematics · Measurement and data · Read proportions in a table Incorrect
Preferred session among survey respondents
SessionResponses
Morning24
Afternoon28
Evening20
No preference8

The table lists 80 survey responses. What percentage chose the afternoon session?

There are 28 afternoon responses out of 80 total. Compute 28 ÷ 80 × 100 = 35%. Using 28 as the percent confuses a count with a fraction of the total.

25%: This uses the 20 evening responses instead of the 28 afternoon responses.

30%: This uses the 24 morning responses instead of the afternoon responses.

35%: Correct. 28 of 80 responses is 35%.

45%: This combines afternoon and no-preference responses rather than counting afternoon responses alone.

Question 74Mathematics · Measurement and data · Variable relationships: compare linear rates and starting values Incorrect
Fares for three trip distances
Distance (km)P fare (dollars)Q fare (dollars)
176
299
31112

Each transport service charges a fixed starting fee plus a constant fee per kilometer. Based on the table, which statement correctly compares the two fees?

For each additional kilometer, P’s fare rises by 2 dollars and Q’s by 3 dollars. Subtracting one kilometer’s charge from the first listed fare gives starting fees of 5 dollars for P and 3 dollars for Q. P therefore has the lower kilometer fee but the higher starting fee; comparing a single total fare would not separate these components.

P has a lower kilometer fee and a lower starting fee than Q.: This correctly compares the kilometer fees but reverses the starting-fee comparison.

P has a higher kilometer fee and a lower starting fee than Q.: This reverses both fee comparisons.

P has a higher kilometer fee and a higher starting fee than Q.: This correctly compares starting fees but reverses kilometer fees.

P has a lower kilometer fee and a higher starting fee than Q.: Correct. P charges 2 per kilometer with a starting fee of 5, while Q charges 3 per kilometer with a starting fee of 3.

Question 75Mathematics · Measurement and data · Mean from a frequency table Incorrect
Books borrowed by five students
Books borrowedNumber of students
12
32
51

The table lists how many books five students borrowed. What is the mean number borrowed per student?

Weight each count by its frequency: 1 × 2 + 3 × 2 + 5 × 1 = 13 books. Divide by 2 + 2 + 1 = 5 students to obtain 2.6 books per student. Averaging the three distinct counts instead would give 3 and ignore their frequencies.

1.8 books: This adds the three distinct counts, 1 + 3 + 5, then divides by five students without weighting frequencies.

2 books: This averages the four students in the repeated-count rows but leaves out the student who borrowed five books.

2.6 books: Correct. The weighted total of 13 divided by five is 2.6 books.

3 books: This averages the three distinct book counts without weighting their frequencies.

Question 76Mathematics · Measurement and data · Circumference from diameter Incorrect

A circular planter has a diameter of 1.7 meters. Using pi = 3.14, what is its circumference in meters? Round to the nearest hundredth.

Your answer: 6.34Correct answer: 5.34 m

Circumference equals pi times diameter, so 3.14 × 1.7 = 5.338 meters. Rounding to the nearest hundredth gives 5.34 meters; doubling 1.7 first would mistake the diameter for the radius.

Question 81Mathematics · Measurement and data · Median of an even-sized data set Incorrect

Six delivery times, in minutes, are 18, 11, 20, 14, 15 and 24. What is their median?

The ordered values are 11, 14, 15, 18, 20 and 24. Average the two central values: (15 + 18) ÷ 2 = 16.5 minutes. Averaging all six gives the mean, not the median.

14.5 minutes: This averages the second and third ordered values.

16.5 minutes: Correct. The two central values average to 16.5.

17 minutes: This is the mean of all six values.

19 minutes: This averages the fourth and fifth ordered values.

Question 84Science · Chemistry · Solution concentration: mass percent Incorrect

A solution is made by dissolving 5 grams of salt in 70 grams of water. What is the salt concentration as a percent by mass? Use the total solution mass in the denominator. Round to the nearest tenth and enter the percent number.

Your answer: 7.7Correct answer: 6.7 %

The solution mass is 5 + 70 = 75 grams. Percent by mass is 5 ÷ 75 × 100 ≈ 6.67%, which rounds to 6.7%. Dividing by the water mass alone (5 ÷ 70) would use the solvent mass rather than the total solution mass.

Question 85Science · Human anatomy and physiology · Urinary system: filtration versus reabsorption Incorrect

A kidney model filters glucose from blood into nephron fluid and then reabsorbs most of it back into blood. Filtration stays unchanged, but glucose reabsorption is reduced. Which paired effect is expected?

The unchanged filtration step supplies the same amount of glucose to nephron fluid. Reduced reabsorption returns less of that glucose to blood, leaving more in the fluid that becomes urine. Filtration into the tubule and reabsorption out of it have opposite directions.

More glucose leaves in urine, and less returns to blood by reabsorption.: Correct. Reducing return to blood leaves more of the filtered glucose available for excretion.

More glucose leaves in urine, and more returns to blood by reabsorption.: This predicts increased return despite the specified reduction in reabsorption.

Less glucose leaves in urine, and less returns to blood by reabsorption.: This gets the return direction right but reverses the consequence for glucose remaining in the tubule.

Less glucose leaves in urine, and more returns to blood by reabsorption.: This reverses both consequences of reduced reabsorption.

Question 86Science · Human anatomy and physiology · Immune system: antibody-producing cells Incorrect

Which cells develop into plasma cells that secrete antibodies?

Activated B lymphocytes can develop into antibody-secreting plasma cells. T lymphocytes support other adaptive immune functions, while macrophages and neutrophils can ingest material. Antigen recognition or phagocytosis is not the same function as producing antibodies.

T lymphocytes: These support cell-mediated immune functions rather than becoming antibody-secreting plasma cells.

B lymphocytes: Correct. B lymphocytes can differentiate into plasma cells.

Macrophages: These ingest material and can present antigens, but do not become plasma cells.

Neutrophils: These provide phagocytic innate defense rather than plasma-cell antibody secretion.

Question 92Science · Human anatomy and physiology · Endocrine system: insulin response after a meal Incorrect

After carbohydrate digestion, blood glucose rises. Which normal response most directly helps bring it toward its earlier level?

Rising blood glucose stimulates insulin release from pancreatic beta cells. Insulin promotes glucose uptake in responsive tissues and storage, helping lower the circulating level. Glucagon has a broadly opposing role in supporting blood glucose when it is low.

Increased glucagon release promoting liver glucose output: This applies the low-glucose response to a high-glucose condition.

Reduced glucose storage as glycogen in the liver: This would reduce removal of glucose from circulation into storage.

Increased insulin release promoting glucose uptake and storage: Correct. Insulin supports uptake and storage in response to rising glucose.

Reduced insulin release limiting cellular glucose uptake: This reverses the normal insulin response and would oppose lowering glucose.

Question 94Science · Human anatomy and physiology · Levels of biological organization Incorrect

Which sequence lists body organization from simpler to more complex?

Similar cells contribute to tissues, and different tissues combine in organs. Organs work together within organ systems. Reversing tissue and organ treats a component as though it were more complex than the structure it helps form.

Cell → tissue → organ → organ system: Correct. This follows increasing levels of organization.

Tissue → cell → organ → organ system: This places tissue before the cells that compose it.

Cell → organ → tissue → organ system: This places an organ before its component tissues.

Organ → tissue → organ system → cell: This breaks the hierarchy and places cells after the systems they help compose.

Question 95Science · Human anatomy and physiology · Nervous system: central and peripheral organization Incorrect

Which structures belong to the central nervous system? Select all that apply.

The central nervous system consists of the brain and spinal cord. The cerebrum and cerebellum are brain regions. Nerves that connect the central nervous system with limbs are part of the peripheral nervous system.

Cerebrum: Correct. The cerebrum is part of the brain.

Spinal cord: Correct. The spinal cord is part of the central nervous system.

Median nerve in the arm: This is a peripheral nerve despite communicating with the spinal cord.

Cerebellum: Correct. The cerebellum is part of the brain.

Sciatic nerve in the leg: This is a peripheral nerve running into the lower limb.

Question 96Science · Human anatomy and physiology · Reproductive system: site of typical fertilization Incorrect

In human reproduction, where does fertilization most commonly occur?

Fertilization most commonly occurs in a uterine tube after an oocyte has been released from an ovary. The resulting early embryo moves toward the uterus, where implantation normally occurs. Fertilization and implantation are separate events at different locations.

Ovary: This confuses the site of oocyte production and release with the usual site of fertilization.

Uterine cavity: This confuses the normal site of implantation with the usual site of fertilization.

Cervix: This confuses a passage into the uterus with the usual meeting site of the gametes.

Uterine (fallopian) tube: Correct. The uterine tube is the usual site of fertilization.

Question 106Science · Scientific reasoning · Interpret data: treatment means and individual variability Incorrect
Root lengths after three weeks
GroupRoot lengths (cm)
No fertilizer6, 7, 11
Fertilizer7, 8, 12

The table shows root lengths for plants randomly assigned to equal growing conditions except for fertilizer. Which conclusion is best supported?

The no-fertilizer mean is (6 + 7 + 11)/3 = 8 cm, and the fertilized mean is (7 + 8 + 12)/3 = 9 cm. Individual values overlap: both groups contain a 7 cm root, and the unfertilized 11 cm root exceeds two fertilized roots. Higher group averages do not imply separation of every individual measurement.

The no-fertilizer group had a higher mean, although the fertilized group included the longest root.: The no-fertilizer mean is 8 cm, below the fertilized mean of 9 cm.

The groups had equal medians, although the fertilized group had a higher mean.: The medians are 7 and 8 cm, not equal.

The fertilized group had a higher mean, and individual measurements from the two groups overlapped.: Correct. The means are 9 and 8 cm, while both groups include a 7 cm root.

The fertilized group had a higher median, although the no-fertilizer group had a higher mean.: The median comparison is correct, but the mean comparison is reversed.

Question 107Science · Scientific reasoning · Evidence and logic: correlation with an alternative explanation Incorrect

A survey finds that neighborhoods with more shade trees have lower afternoon outdoor temperatures. Those neighborhoods also have fewer paved surfaces. What conclusion is justified from the survey alone?

The survey shows an association between trees and temperature. Paved surfaces differ at the same time, providing another possible explanation or contribution. Without a design that separates these factors, neither one can be established as the sole cause.

More trees are associated with lower temperatures, but differing amounts of paving prevent the survey from isolating the tree effect.: Correct. The association is observed, but the differing paving limits causal attribution.

More trees have no association with lower temperatures, because the neighborhoods differ in paving as well as in tree abundance.: This rejects an observed association merely because causation is uncertain.

More trees are established as the sole cause of lower temperatures, because both tree abundance and temperature were measured together.: This assigns sole causation without accounting for the second changing factor.

Less paving is established as the sole cause of lower temperatures, because paved surface area differs between the surveyed neighborhoods.: This replaces one unsupported sole-cause claim with another.

Question 110Science · Scientific reasoning · Scientific method: a testable hypothesis Incorrect

A student investigates whether the size of an opening in a container affects how quickly hot water cools. Which statement is a testable prediction about that relationship?

The appropriate prediction connects the investigated variable, opening size, to the measured cooling outcome. Matching starting conditions makes that relationship testable. A procedure can support the test, but it is not itself a prediction.

With starting conditions matched, water in containers with larger openings will cool to room temperature sooner.: Correct. This predicts the cooling outcome while varying the opening size and matching other starting conditions.

Containers with larger openings will hold a greater volume of water at the beginning of each test.: This predicts a starting volume rather than the cooling outcome and would introduce a confound.

Use equal water volumes and starting temperatures in containers with different opening sizes.: This gives a useful procedure but does not predict a cooling outcome.

With opening size matched, water at a higher starting temperature will take longer to reach room temperature.: This predicts an effect of starting temperature while keeping opening size fixed, testing a different relationship.

Question 111Science · Scientific reasoning · Experiment design: identify a manipulated variable Incorrect

Students grow seedlings under lamps for 4, 8 or 12 hours each day. They keep seed type, soil and water amount the same and measure height after two weeks. What is the independent variable?

The independent variable is the factor intentionally changed among groups, here the daily light duration. Height is the measured dependent variable. Keeping soil and water the same makes those controlled conditions.

Seedling height after two weeks: This is the measured outcome rather than the manipulated condition.

Amount of water provided: This is held constant rather than deliberately changed.

Type of soil used: This is held constant rather than deliberately changed.

Hours of light per day: Correct. Students deliberately vary daily light duration.

Question 112Science · Scientific reasoning · Experiment design: controlled variables Incorrect

A student compares germination of one seed variety at three temperatures. Seeds are assigned randomly to groups, and germination is recorded after seven days. Which conditions should be kept the same among groups to isolate temperature? Select all that apply.

Matching group size, water and growing medium improves the temperature comparison. Temperature is deliberately varied, and germination count is the outcome to measure. Forcing the germination outcome to match would prevent the experiment from detecting an effect.

Number of seeds placed in each group: Correct. Equal initial group sizes support direct comparison of germination results.

Temperature used for each group: This is the independent variable and must differ as specified.

Amount of water given to each group: Correct. Water can affect germination, so it should be controlled.

Type of growing medium used: Correct. Growing medium can affect germination, so it should be controlled.

Number of seeds that germinate: This is the dependent outcome, which must be measured rather than fixed.

The table reports melting time for identical ice cubes under matched conditions. If melting time keeps decreasing as air temperature rises, which interval must contain the melting time at 35°C?

If melting time keeps decreasing as temperature rises, the time at 35°C must lie between the times at 30°C and 40°C: between 48 and 36 seconds. A midpoint such as 42 seconds is an estimate, not a bound the data guarantee.

Between 36 and 42 seconds: 42 seconds is only an estimate at the midpoint; the data do not show that the time at 35°C must be 42 seconds or less.

Between 36 and 48 seconds: Correct. The neighboring observations at 30°C and 40°C provide times of 48 and 36 seconds.

Between 42 and 48 seconds: 42 seconds is only an estimate at the midpoint; the data do not show that the time at 35°C must be 42 seconds or more.

Between 48 and 65 seconds: This uses the observations at 20°C and 30°C rather than those immediately neighboring 35°C.

Question 114Science · Biology · Mitosis: chromosome events Incorrect

Arrange these events in the order of mitosis, from its beginning to its end.

Unordered Options

Ordered Response

  1. 1.Nuclear envelopes form around the separated chromosome sets.✗
  2. 2.Sister chromatids separate toward opposite poles.✗
  3. 3.Chromosomes align at the cell equator.✗
  4. 4.Chromosomes condense as division begins.✗

Correct order: 1. Chromosomes condense as division begins. 2. Chromosomes align at the cell equator. 3. Sister chromatids separate toward opposite poles. 4. Nuclear envelopes form around the separated chromosome sets.

Chromosomes condense, align, separate and are enclosed in new nuclei. These events correspond to prophase, metaphase, anaphase and telophase. DNA replication occurs earlier in the cell cycle and is not one of the listed mitotic events.

Question 118Science · Chemistry · Chemical reactions: balance an equation Incorrect

For the reaction Al + O₂ → Al₂O₃, which coefficients of Al, O₂ and Al₂O₃, respectively, balance the equation using the smallest whole numbers?

Two Al₂O₃ units contain four aluminum atoms and six oxygen atoms. Four Al atoms and three O₂ molecules supply those amounts, giving coefficients 4, 3 and 2. Counting oxygen molecules as single atoms would give an incorrect oxygen coefficient.

2, 3, 2: This balances oxygen but leaves two aluminum atoms on the left and four on the right.

4, 2, 2: This balances aluminum but supplies four oxygen atoms for six on the right.

4, 3, 2: Correct. Both sides contain four aluminum atoms and six oxygen atoms.

4, 3, 3: This leaves six aluminum and nine oxygen atoms on the product side.

Question 119Science · Chemistry · Changes of state: evaporation below boiling Incorrect

Water in an open dish slowly decreases at room temperature, well below its boiling point. What process best explains the loss?

Some water molecules at the surface have enough energy to enter the gas phase even below the boiling point. That process is evaporation. Boiling produces vapor throughout the liquid and requires the relevant boiling conditions.

Condensation throughout the liquid: This describes gas becoming liquid, which would add water rather than remove it.

Evaporation at the liquid surface: Correct. Surface molecules can escape into the gas phase below boiling temperature.

Melting at the liquid surface: This describes solid becoming liquid rather than liquid becoming gas.

Boiling throughout the liquid: This confuses surface evaporation with vapor formation throughout a boiling liquid.

Question 123Science · Chemistry · Dilution: concentration from conserved solute Incorrect

A 20 mL sample contains 4 grams of a dissolved solid. Water is added until the final volume is 80 mL, with no solid lost. What is the final concentration in grams per milliliter?

Dilution changes the volume but preserves the 4 grams of solute. Divide 4 grams by the final 80 mL to get 0.05 g/mL. Using the original 20 mL would report the starting concentration instead of the diluted concentration.

0.025 g/mL: This doubles the final volume a second time before dividing.

0.05 g/mL: Correct. 4 grams divided by 80 mL equals 0.05 g/mL.

0.20 g/mL: This uses the original volume and reports the initial concentration.

0.80 g/mL: This multiplies the initial concentration by the volume increase instead of dividing.

Question 124Science · Biology · Cell membranes: osmosis Incorrect

A cell is placed in a solution with a higher concentration of nonpenetrating solute than its cytoplasm. Water can cross the cell membrane, but the solute cannot. Which initial change is expected?

Water initially moves out of the cell toward the solution with the higher concentration of nonpenetrating solute. Losing water makes the cell shrink. The solute cannot equalize its concentration by crossing because the stem explicitly rules that out.

Water enters, and the cell swells.: This reverses water movement in the described hypertonic surroundings.

Solute enters, and the cell grows.: This overlooks the specified inability of the solute to cross.

Water movement is balanced, and cell size stays the same.: This treats unequal nonpenetrating-solute concentrations as an isotonic condition.

Water leaves, and the cell shrinks.: Correct. The net initial water movement is outward, reducing cell volume.

Question 125Science · Biology · Macromolecules: enzyme catalytic role Incorrect

How does an enzyme typically speed up a chemical reaction?

An enzyme provides a reaction pathway with lower activation energy. It is regenerated after catalysis and does not change the reaction equilibrium. Confusing a catalyst with a reactant would incorrectly imply that it is permanently used up.

By increasing the amount of product required for equilibrium: This confuses reaction rate with the equilibrium amounts.

By being permanently used up with each product molecule: This treats the enzyme as a consumed reactant.

By lowering the activation energy of the reaction: Correct. Lower activation energy increases the reaction rate.

By changing the identities of the starting atoms: This mistakes a chemical catalyst for a process changing atomic identities.

Question 126Science · Biology · Microorganisms: bacterial cell organization Incorrect

Which feature distinguishes a typical bacterium from a typical animal cell?

Bacteria are prokaryotes and do not enclose their DNA in a membrane-bound nucleus. They still have DNA, ribosomes and a plasma membrane. Their usual cell division is binary fission rather than the meiosis used to form gametes in sexually reproducing organisms.

Its DNA is not enclosed in a membrane-bound nucleus.: Correct. Bacterial DNA occupies a nucleoid rather than a membrane-bound nucleus.

It lacks both DNA and ribosomes.: This mistakes absence of a nucleus for absence of genetic material and ribosomes.

Its plasma membrane contains no lipids.: This assumes a simpler cell lacks the lipid basis of a membrane.

It reproduces by meiosis to form gametes.: This applies a eukaryotic reproductive process to bacteria.

Question 130Science · Biology · Proteins: structure and temperature Incorrect

An enzyme works well at room temperature but loses most of its activity after strong heating. Which explanation best connects its structure to this change?

Many enzymes are proteins whose activity depends on their three-dimensional shape. Strong heating can disrupt that shape and reduce substrate binding. Enzymes lower activation energy rather than supply the energy consumed by a reaction.

Heat lowers substrate concentration even when the same amount of substrate is supplied.: This attributes loss of activity to missing substrate rather than a change in enzyme shape.

Heat can alter its shape, reducing the fit between its active site and substrate.: Correct. A changed active-site shape can reduce substrate binding and catalysis.

Heat permanently uses up enzyme molecules, as though they were reaction substrates.: This treats a catalyst as a consumed reactant rather than considering its altered shape.

Heat makes each enzyme molecule supply less energy to the reaction.: This assigns an energy-supply role to an enzyme rather than its catalytic role.

Question 131Science · Biology · Meiosis: homologous chromosomes and sister chromatids Incorrect

After normal meiosis I, each daughter cell has one chromosome from each homologous pair, and each chromosome still has two sister chromatids. What must happen in meiosis II to form gametes with unduplicated chromosomes?

Meiosis I separates homologous chromosomes and reduces the number of chromosome sets. Meiosis II separates sister chromatids without another round of DNA replication. Copying DNA again would oppose the production of gametes with unduplicated chromosomes.

Homologous chromosomes must pair again.: This repeats an earlier pairing event instead of completing chromatid separation.

DNA must be copied again before separation.: This inserts an extra DNA replication that does not occur between the meiotic divisions.

The homologous chromosome number must double.: This reverses the reduction in chromosome sets.

Sister chromatids must separate into different cells.: Correct. Meiosis II separates the sister chromatids that remain together after meiosis I.

Question 137English and Language Usage · Conventions of standard English · Punctuation: commas after introductory clauses Incorrect

Which sentence correctly separates the introductory dependent clause from the main clause?

After the guests arrived is the entire introductory clause, so the comma belongs after arrived. Moving the comma within either clause separates words that must function together.

After the guests arrived, the host began the tour.: Correct. The comma follows the entire introductory dependent clause.

After, the guests arrived the host began the tour.: This splits the subordinating word from the clause it introduces.

After the guests, arrived the host began the tour.: This separates the dependent clause’s subject from its verb.

After the guests arrived the host, began the tour.: This places the comma between the main clause’s subject and verb.

Question 144English and Language Usage · Conventions of standard English · Punctuation: apostrophes in plural possessives Incorrect

Three editors jointly prepared a report. Which phrase correctly identifies the report as belonging to all three editors?

The regular plural is editors, so its possessive is editors’. Editor’s would identify one editor as the owner, changing the stated meaning.

the editors report’s: This places possession on report and leaves the owners unmarked.

the editors’ report: Correct. A plural noun ending in s takes an apostrophe after that s to show possession.

the editors’s report: This adds another s to a regular plural possessive.

the editor’s report: This makes the owner singular, although the stem specifies three editors.

Question 149English and Language Usage · Using language and vocabulary to express ideas in writing · Context clues: definition in apposition Incorrect

What does concise mean in this sentence? “The editor requested a concise summary, one that kept the essential points in very few words.”

The phrase after the comma explains the meaning of concise. A concise summary is brief while preserving essential points, so brevity alone does not mean incompleteness.

Informal enough to sound conversational: This invents a tone requirement unrelated to the definition.

Brief while retaining essential information: Correct. The explanatory phrase defines concise as brief but complete in its essentials.

Uncertain because information is missing: This confuses brevity with loss of essential information.

Detailed enough to include every example: This ignores the stated requirement to use very few words.

Question 152English and Language Usage · Knowledge of language · Concise wording: removing repeated meaning Incorrect

Which revision preserves the meaning while removing redundancy? “The final outcome was that all of the participants returned back to the hall.”

Outcome already indicates a result, and returned already expresses going back. All must remain because it specifies every participant rather than an unspecified group.

The outcome was that all participants returned to the hall.: Correct. It removes final, of the, and back while preserving the stated outcome for all participants.

The final outcome was that all participants returned back to the hall.: This removes one wordy phrase but retains final outcome and returned back.

The outcome was that participants returned to the hall.: This drops all and therefore no longer states that every participant returned.

All participants eventually left the hall.: This reverses the direction of movement instead of preserving the meaning.

Question 155English and Language Usage · Knowledge of language · Register: adapting technical information for visitors Incorrect

An internal memo reads, “Access is contingent upon prior authorization.” A visitor notice must preserve that requirement in language a general audience can readily understand. Which revision best meets both goals?

The notice must both simplify the language and retain the condition of advance permission. Receive permission before entering does both; a revision that changes the timing or discusses directions loses essential information.

Access remains contingent upon advance authorization.: This preserves the meaning but keeps the technical wording the notice should simplify.

You must receive permission before entering.: Correct. This preserves advance permission while expressing the requirement in familiar words.

Please ask a staff member if you need directions.: This substitutes a directions request for the permission requirement.

You may request permission after entering.: This reverses the timing of the permission requirement.

Question 157English and Language Usage · Knowledge of language · Grammar: parallel structure in lists Incorrect

Which sentences use parallel grammatical forms for all three listed activities? Select all that apply.

Parallel lists present equal activities in matching grammatical forms. Sorting, labeling, and scanning match, as do to sort, to label, and to scan. A list that mixes those forms forces the reader to reinterpret its structure.

The role involves sorting records, labeling folders, and scanning forms.: Correct. Each activity is expressed as an -ing phrase.

The role involves sorting records, labels on folders, and scanning forms.: This places a noun phrase between two -ing activity phrases.

The team plans to sort records, to label folders, and to scan forms.: Correct. Each activity is expressed as a to-infinitive phrase.

The team plans sorting records, to label folders, and scanned forms.: This mixes an -ing phrase, an infinitive, and a past-tense or participial form.

The tasks are to sort records, labeling folders, and forms to scan.: This mixes an infinitive, an -ing phrase, and a noun with an infinitive modifier.

Question 158English and Language Usage · Using language and vocabulary to express ideas in writing · Writing process: revising relevance Incorrect

A paragraph argues that a shared desk calendar helps coworkers avoid overlapping room reservations and use newly open times. Which details directly develop that focus? Select all that apply.

Relevant details must show how the calendar helps coworkers avoid overlapping reservations or use newly open times. Seeing existing reservations and noticing cancellations do that. Birthdays, bus times and print colors may be useful or pleasant, but they do not develop the paragraph's focus.

Coworkers can see existing reservations before choosing a time.: Correct. Checking existing reservations directly helps coordinate use of the room.

Each calendar page also lists the birthdays of coworkers.: This is a familiar calendar feature, but birthday information does not identify room reservations or openings.

Updates let coworkers notice cancellations and reuse open periods.: Correct. Visible cancellations help coworkers coordinate newly available times.

A reference section lists public bus departure times near the office.: This offers useful scheduling information about travel rather than room reservations or openings.

Calendar entries can be printed in several colors.: Print colors change how the calendar looks, not how coworkers find reservations or open times.

Question 166English and Language Usage · Knowledge of language · Grammar: consistent verb tense in narration Incorrect

The paragraph reports completed events yesterday. Which revision corrects the tense shift? “Suri unlocked the office, checks the messages, and filed the receipts.”

The three actions occurred in the same completed past sequence. Unlocked, checked, and filed keep that time frame consistent; no earlier past event is identified that would require past perfect.

Suri unlocks the office, checked the messages, and filed the receipts.: This changes the first action to present tense while leaving the others past.

Suri unlocked the office, has checked the messages, and files the receipts.: This introduces present perfect and present tense into the completed past sequence.

Suri had unlocked the office, checks the messages, and filed the receipts.: This leaves the present-tense checks in a sequence of past actions.

Suri unlocked the office, checked the messages, and filed the receipts.: Correct. All three completed actions are expressed in simple past tense.

Question 167English and Language Usage · Using language and vocabulary to express ideas in writing · Context clues: sequence Incorrect

Which meaning of provisional fits the sentence? “The schedule is provisional; after the room assignments are confirmed, we will issue the final version.”

The later final version shows that the current schedule is not settled. Provisional therefore means temporary or subject to revision, rather than fully approved.

Public and widely distributed: This confuses the schedule’s status with how broadly it is shared.

Detailed and fully approved: This ignores the contrast between provisional and final.

Temporary and subject to change: Correct. The contrast with a later final version indicates a temporary arrangement.

Late and no longer useful: This invents an overdue status that the sentence does not mention.
