A computer science instructor reported outcomes from a new grading policy in an introductory programming course. In 2022, the course had 180 students and used a traditional points-based system: three midterm exams (each worth 20% of the grade), weekly quizzes (20%), and a final project (20%). In 2023, with 192 students, the instructor replaced the points-based system with a "mastery" model in which students could retake quizzes up to two times, and the lowest midterm score was dropped. The report stated that the final project remained required in both years and that its rubric was unchanged. Average course grades (on a 4.0 scale) were reported as 2.74 in 2022 and 2.89 in 2023. The instructor also noted that the 2023 course used the same textbook edition as 2022.
According to the passage, which of the following is true?
Answer: In 2023, students could retake quizzes up to two times.
This question tests detail comprehension by asking which statement is true according to the passage. Correct answers in such questions restate explicit information from the text without adding inferences or external knowledge. The relevant detail is in the third sentence, which describes the 2023 grading policy. This sentence states that in 2023, the mastery model allowed students to retake quizzes up to two times. Choice A matches this text by restating the retake policy for quizzes in 2023. A representative distractor, like choice E, fails because it reverses the grade trend; the passage reports an increase from 2.74 in 2022 to 2.89 in 2023. This distractor inverts the numbers.

A materials science paper describes tensile testing of a biodegradable polymer blend made from polylactic acid (PLA) and polybutylene adipate terephthalate (PBAT). The blend was prepared at three mass ratios—70:30, 60:40, and 50:50 PLA:PBAT—using a twin-screw extruder operated at 180°C. Dog-bone specimens were injection molded and conditioned for 48 hours at 23°C and 50% relative humidity before testing. The passage states that tensile tests were performed according to ASTM D638 at a crosshead speed of 5 mm/min, and that elongation at break was calculated from the displacement data recorded by the testing machine. The authors report that the 70:30 blend had the highest tensile strength among the three formulations. They also mention that a compatibilizer (maleic-anhydride-grafted PLA) was added at 2% by mass to all blends.
The passage states that…
Answer: The twin-screw extruder was operated at 180°C.
This question tests comprehension of specific details presented in the passage. The correct answer must be information explicitly stated in the text without requiring interpretation. The passage explicitly states that the blend was prepared "using a twin-screw extruder operated at 180°C," making option A the correct answer. This processing parameter is presented as a factual detail about the experimental methodology. Option B is incorrect because the passage states tensile tests were performed "at a crosshead speed of 5 mm/min," not 50 mm/min as the option claims.

A pharmacology trial compared two dosing schedules for the same antihypertensive medication. The trial enrolled 320 adults with stage 1 hypertension and assigned 160 to Schedule M (one 20 mg dose each morning) and 160 to Schedule E (one 20 mg dose each evening). Blood pressure was measured at baseline and again after 12 weeks, using the same automated cuff model at all sites. The paper reported that mean systolic blood pressure decreased by 9.4 mmHg in Schedule M and by 10.1 mmHg in Schedule E. The authors also reported that 14 participants in Schedule M and 17 in Schedule E discontinued due to adverse effects. The paper stated that participants were instructed not to change their diet during the study, but dietary intake was not monitored.
The passage states that…
Answer: Schedule E involved one 20 mg dose each evening.
This question tests detail comprehension by asking what the passage states. Correct answers in such questions restate explicit information from the text without adding inferences or external knowledge. The relevant detail is in the second sentence, which describes the dosing schedules. This sentence assigns 160 participants to Schedule E, involving one 20 mg dose each evening. Choice B matches this text by restating the schedule and dosage for Schedule E. A representative distractor, like choice D, fails because it claims blood pressure was measured only once at the end, but the passage states measurements at baseline and after 12 weeks. This distractor omits the baseline measurement.

A museum conservation lab evaluated two varnish-removal solvents on 30 oil paintings dated between 1880 and 1910. Solvent X was a mixture of ethanol and acetone in a 3:1 ratio by volume; Solvent Y was a gel containing a proprietary hydrocarbon blend. Each painting was divided into two adjacent test areas of equal size, and conservators applied Solvent X to one area and Solvent Y to the other for a standardized dwell time of 90 seconds. After treatment, they measured remaining varnish thickness using a handheld optical device. The lab reported that Solvent X reduced varnish thickness by an average of 42%, while Solvent Y reduced it by an average of 35%. The report also stated that in 6 of the 30 paintings, Solvent Y left a visible residue that required an additional rinse step, whereas Solvent X did not require rinsing in any case. No pigment loss was observed in either test area for 27 of the paintings; the remaining 3 paintings showed minor pigment disruption in both areas.
According to the passage, which of the following is true?
Answer: Solvent X was applied for 90 seconds and reduced varnish thickness by an average of 42%.
This question tests detail comprehension by asking which statement is true according to the passage. Correct answers in such questions restate explicit information from the text without adding inferences or external knowledge. The relevant detail is in the fourth sentence, which describes the application process for the solvents. This sentence notes that conservators applied each solvent for a standardized dwell time of 90 seconds, and the fifth sentence reports that Solvent X reduced varnish thickness by an average of 42%. Choice B matches this text by combining the dwell time with the reduction percentage for Solvent X. A representative distractor, like choice A, fails because it attributes the 42% reduction to Solvent Y, whereas the passage explicitly assigns 35% to Solvent Y. This distractor confuses the results between the two solvents.
- A climatology note describes the instrumentation at the Alpine Ridge weather station. The note states that the station is located at an elevation of 2,480 meters and began continuous operation on October 1, 1998. The station measures air temperature at 2 meters above ground and wind speed at 10 meters above ground. Precipitation is recorded with a tipping-bucket gauge that has a resolution of 0.2 millimeters per tip. The note also specifies that data are logged at 10-minute intervals and transmitted via satellite once per day at 02:00 local time. As a maintenance detail, the note reports that the temperature sensor is calibrated twice per year: in April and in October.
According to the passage, which of the following is true?
Answer: Precipitation is recorded with a tipping-bucket gauge with a resolution of 0.2 millimeters per tip.
This question tests detail-specific information by asking which statement accurately reflects the instrumentation specifications. Correct answers restate explicit technical details from the climatology note without inference. The passage states "Precipitation is recorded with a tipping-bucket gauge that has a resolution of 0.2 millimeters per tip," which exactly matches choice A. This technical specification appears in the middle of the passage describing the station's measurement capabilities. Choice B is incorrect because the passage states wind speed is measured at 10 meters, not 2 meters above ground. Choice C incorrectly states 1-minute intervals when the passage specifies 10-minute intervals for data logging.

A transportation agency evaluated a pilot program that replaced some curbside parking with protected bicycle lanes on Alder Avenue. The pilot covered a 1.6-mile segment between 3rd Street and 19th Street and was implemented in May 2021. According to the agency's report, the project removed 112 on-street parking spaces and added 0.8 miles of protected bike lane (counting one direction only). The report also stated that average weekday bicycle counts at a mid-segment counter increased from 420 in June 2020 to 690 in June 2021. However, the agency noted that traffic signal timing was also adjusted in April 2021 to reduce vehicle speeds, and it did not claim that the bike lane alone caused the increase in cycling. The report did not include weekend bicycle counts.
The passage states that…
Answer: The project removed 112 on-street parking spaces.
This question tests detail comprehension by asking what the passage states. Correct answers in such questions restate explicit information from the text without adding inferences or external knowledge. The relevant detail is in the third sentence, which describes the project's impact on parking. This sentence states that the project removed 112 on-street parking spaces. Choice D matches this text by restating the exact number of parking spaces removed. A representative distractor, like choice C, fails because it attributes a causal claim to the report that is not present; the passage explicitly notes that the agency did not claim the bike lane alone caused the cycling increase. This distractor adds an unstated assertion.

A political science article analyzes archival records from a 1974 parliamentary committee in order to track how amendments were negotiated. The author examined 312 pages of meeting minutes stored in a national archive and cross-referenced them with 46 newspaper articles published during the same month. The passage specifies that the committee met on five dates—March 4, March 7, March 11, March 18, and March 25—and that the March 11 session lasted 6 hours, longer than any other session. The author notes that only two members spoke in every meeting and that the chair formally called for a vote on three amendments, all of which passed. In describing limitations, the passage states that audio recordings were not available and that the minutes occasionally omitted the names of speakers when multiple people interrupted each other.
Which of the following is mentioned in the passage?
Answer: The March 11 session lasted 6 hours.
This question requires identifying a detail that is explicitly mentioned in the passage. The correct answer must reflect information stated directly in the text rather than requiring inference. The passage explicitly states that "the March 11 session lasted 6 hours, longer than any other session," making option B the correct answer. This specific detail about the duration of one particular committee meeting is presented as a factual statement. Option C is incorrect because the passage states that "the chair formally called for a vote on three amendments, all of which passed," contradicting the claim that all three amendments failed.

A historian summarized the publication history of a scientific treatise by the chemist Elara Minton. The treatise first appeared in 1894 as a 212-page volume printed in Bristol, with a print run of 600 copies. A second edition was published in 1901, expanded to 248 pages and printed in London, and it included a new appendix describing Minton's laboratory apparatus for gas collection. The historian noted that the 1901 edition's preface explicitly thanked two colleagues, R. Sato and J. Hargreaves, for reviewing early drafts. A third edition was issued in 1913, but the historian stated that it was a "photo-reproduction" of the 1901 edition and did not add new material. The summary did not mention any translations.
Which of the following is mentioned in the passage?
Answer: The 1901 edition included a new appendix describing laboratory apparatus for gas collection.
This question tests detail comprehension by asking which statement is mentioned in the passage. Correct answers in such questions restate explicit information from the text without adding inferences or external knowledge. The relevant detail is in the third sentence, which describes the 1901 edition. This sentence states that the 1901 edition included a new appendix describing laboratory apparatus for gas collection. Choice D matches this text by identifying the edition and the content of the new appendix. A representative distractor, such as choice C, fails because it attributes a new appendix on gas collection to the 1913 edition, but the passage describes the 1913 as a photo-reproduction without new material. This distractor confuses the editions.
- Read the passage and answer the question.
A climatology note described how a regional weather station network handled missing data. The network consisted of 14 stations, each recording hourly temperature and precipitation. For temperature, if fewer than 3 consecutive hours were missing, the network filled gaps by linear interpolation between the nearest available observations. If 3 or more consecutive hours were missing, the data were left as missing and excluded from daily averages. For precipitation, however, the note stated that no interpolation was performed; missing precipitation values were treated as missing regardless of gap length. The note also specified that all timestamps were stored in Coordinated Universal Time (UTC), even though the stations were located in a single time zone.
According to the passage, which of the following is true?
Answer: All timestamps were stored in Coordinated Universal Time (UTC).
This question tests detail comprehension by asking which statement is true according to the passage. Correct answers in such questions restate explicit information from the text without adding inferences or external knowledge. The relevant detail is in the last sentence, which discusses timestamp storage. This sentence specifies that all timestamps were stored in Coordinated Universal Time (UTC). Choice B matches this text by restating the use of UTC for timestamps. A representative distractor, such as choice D, fails because it misstates the number of stations as 24 and the recording frequency as daily, whereas the passage describes 14 stations recording hourly. This distractor alters key details.

A linguist analyzing changes in coastal dialects compiled a corpus of recorded interviews from the town of Greyhaven. The corpus consisted of 96 interviews: 48 recorded in 1975 and 48 recorded in 2015. Each interview lasted exactly 30 minutes, and all speakers were lifelong residents of Greyhaven. The linguist focused on the pronunciation of the vowel in words like "boat" and coded each instance as either a "raised" or "non-raised" variant. In the 1975 recordings, 31% of coded instances were raised; in the 2015 recordings, 54% were raised. The study explicitly noted that the 2015 speakers had a higher average level of formal education than the 1975 speakers, but it did not provide the education averages. The linguist also stated that the interviews were conducted by different fieldworkers in the two years.
According to the passage, which of the following is true?
Answer: In the 2015 recordings, 54% of coded instances were classified as raised.
This question tests detail comprehension by asking which statement is true according to the passage. Correct answers in such questions restate explicit information from the text without adding inferences or external knowledge. The relevant detail is in the sixth sentence, which provides the percentages of raised vowel variants in the recordings. This sentence states that in the 2015 recordings, 54% of coded instances were raised. Choice B matches this text exactly by restating the year and the 54% figure for raised instances. A representative distractor, like choice D, fails because it introduces a specific interview length of 45 minutes, whereas the passage explicitly states each lasted exactly 30 minutes. This distractor alters a stated detail to create confusion.

A public health department assessed the impact of a new appointment system at four vaccination clinics. Before the change, all four clinics operated on a walk-in basis. Beginning March 1, 2022, two clinics shifted to scheduled appointments in 15-minute slots, while the other two remained walk-in. The department compared average waiting time (from arrival to vaccination) during April 2022. The two appointment clinics reported mean waits of 22 minutes and 26 minutes, respectively. The two walk-in clinics reported mean waits of 41 minutes and 44 minutes. The report also stated that staffing levels were unchanged from February to April at three clinics; the fourth clinic added one nurse in mid-March, but it was one of the walk-in clinics. The department did not report the number of patients served at each clinic.
Which of the following is mentioned in the passage?
Answer: One of the walk-in clinics added a nurse in mid-March.
This question tests detail comprehension by asking which statement is mentioned in the passage. Correct answers in such questions restate explicit information from the text without adding inferences or external knowledge. The relevant detail appears in the seventh sentence, which discusses staffing changes at the clinics. This sentence states that staffing levels were unchanged at three clinics, but the fourth clinic added one nurse in mid-March, and it was one of the walk-in clinics. Choice C matches this text by identifying the addition of a nurse at one walk-in clinic in mid-March. A representative distractor, such as choice D, fails because it generalizes a reduction in waiting times to all clinics under 30 minutes, but the passage reports specific means of 22, 26, 41, and 44 minutes. This distractor adds an unstated threshold and implication.

An archaeology report described a survey of ceramic fragments at the Tel Harun site. The team excavated four trenches, each measuring 2 meters by 5 meters, during a 12-day season in October 2023. In total, the team cataloged 1,460 ceramic fragments. Of these, 310 were classified as "rim sherds," 980 as "body sherds," and 170 as "base sherds," with the categories defined in the report's methods section. The report stated that carbon dating was performed on two charcoal samples from Trench 3, yielding calibrated dates centered on 740 BCE and 710 BCE. The report explicitly noted that no human remains were recovered.
Which of the following is mentioned in the passage?
Answer: Carbon dating was performed on two charcoal samples from Trench 3.
This question tests detail comprehension by asking which statement is mentioned in the passage. Correct answers in such questions restate explicit information from the text without adding inferences or external knowledge. The relevant detail is in the fifth sentence, which discusses carbon dating. This sentence states that carbon dating was performed on two charcoal samples from Trench 3. Choice B matches this text by identifying the method, number of samples, and trench. A representative distractor, such as choice E, fails because it claims all trenches measured 5 meters by 5 meters, but the passage specifies 2 meters by 5 meters. This distractor changes the stated dimensions.

A research team studying bilingual education examined 240 middle-school students in three districts. District A used a "90–10" immersion model: in sixth grade, 90% of instruction time was in Spanish and 10% in English. District B used a "50–50" model, splitting instruction time equally between Spanish and English. District C offered traditional English-only instruction but provided an elective Spanish class that met three times per week for 45 minutes. The team administered the same standardized reading test in English at the end of seventh grade. Mean scores were 78 in District A, 81 in District B, and 79 in District C (on a 100-point scale). The report explicitly stated that the test was not translated and that no Spanish reading assessment was administered. The team also noted that District B had the highest proportion of certified bilingual teachers (84%), while District A had 71% and District C had 12%. The authors cautioned that the districts differed in median household income, but they did not provide income figures.
Which of the following is mentioned in the passage?
Answer: District B had the highest proportion of certified bilingual teachers, at 84%.
This question tests detail comprehension by asking which statement is mentioned in the passage. Correct answers in such questions restate explicit information from the text without adding inferences or external knowledge. The relevant detail is found in the seventh sentence, which discusses the proportion of certified bilingual teachers in each district. This sentence states that District B had the highest proportion at 84%, while District A had 71% and District C had 12%. Choice C matches this text precisely by identifying District B's 84% figure. A representative distractor, like choice E, fails because it attributes a causal conclusion to the authors that is not stated; the passage reports scores but does not conclude that one model causes higher scores. The authors only cautioned about confounding factors like income differences.
- A 2021 archaeology paper describes the excavation of a coastal site at Cape Lumen. The authors state that the excavation grid covered exactly 24 square meters and was divided into 96 equal squares. Charcoal samples were collected from two distinct layers: Layer 2 and Layer 4. The paper explicitly reports that 14 charcoal samples from Layer 2 were submitted for radiocarbon dating, while 6 charcoal samples from Layer 4 were submitted. The laboratory used accelerator mass spectrometry (AMS) for all submitted samples. The paper also notes, as a minor methodological detail, that all sediment was dry-sieved through 3-millimeter mesh, and that shell fragments larger than 2 centimeters were weighed separately from smaller fragments. In discussing results, the authors mention that the median calibrated age for the Layer 2 samples was 2,350 years before present.
The passage states that…
Answer: The excavation grid covered 24 square meters and was divided into 96 equal squares.
This question tests detail comprehension by requiring identification of explicitly stated information from the archaeological report. Correct answers must precisely match what is written in the passage without adding interpretation. The passage clearly states "the excavation grid covered exactly 24 square meters and was divided into 96 equal squares," which directly corresponds to choice A. This information appears early in the passage as a factual description of the excavation methodology. Choice B incorrectly identifies Layer 4 instead of Layer 2 for the median age of 2,350 years. Choice C states 20 samples when the passage explicitly mentions 14 samples from Layer 2 were submitted for dating.

According to administrative records cited in the brief, 58% of awarded firms were in retail or food service, 21% were in personal services, and the remaining 21% were in other sectors. The brief also reported that grantees were required to submit a one-page spending report within 120 days of receiving funds, but the brief did not summarize the contents of those reports.
Which of the following is mentioned in the passage?
Answer: The program awarded 500 grants of $10,000 each in 2021.
This question tests detail comprehension by asking which statement is mentioned in the passage. Correct answers in such questions restate explicit information from the text without adding inferences or external knowledge. The relevant detail is in the second sentence, which describes the grant awards. This sentence states that the program awarded 500 grants of $10,000 each in 2021. Choice A matches this text by restating the number of grants, amount, and year. A representative distractor, like choice D, fails because it claims the brief summarized spending reports, but the passage notes that the brief did not summarize their contents. This distractor adds an unstated action.

An economics article summarizes a randomized controlled trial of a text-message reminder program for property-tax payments in a mid-sized municipality. The trial enrolled 12,000 households that had been at least 30 days delinquent in the previous tax year. Households were randomly assigned to one of three groups: 4,000 received no messages, 4,000 received a single reminder 14 days before the due date, and 4,000 received two reminders—one 14 days before and one 3 days before the due date. The passage explicitly states that the due date for the tax installment studied was October 31, 2022. Payment outcomes were assessed using administrative records on November 30, 2022. The article reports that the two-reminder group had a 6.2 percentage-point higher on-time payment rate than the control group, and it notes that messages were sent in both English and Spanish. The municipality's average delinquent balance at baseline was $740 per household, and the passage specifies that households with balances above $5,000 were excluded from the study.
The passage states that…
Answer: Households with balances above $5,000 were excluded from the study.
This question tests comprehension of specific details presented in the passage. The correct answer must reflect information explicitly stated in the text without requiring any inference. The passage explicitly states in the final sentence that "households with balances above $5,000 were excluded from the study," making option A the correct answer. This exclusion criterion is presented as a factual detail about the study's methodology. Option B is incorrect because while October 31, 2022 was the tax due date, the passage states that payment outcomes were assessed on November 30, 2022, not October 31.

A marine biology article reported on a tagging study of juvenile loggerhead turtles conducted off the coast of South Carolina. Researchers captured 64 turtles between July 10 and August 2, 2019, and attached satellite tags programmed to transmit location data every 6 hours. The article stated that 52 of the 64 tags transmitted for at least 30 days, while 19 transmitted for at least 90 days. The researchers defined "nearshore" as waters within 20 kilometers of the coastline and reported that, during the first 14 days after release, 41 turtles remained nearshore for at least 80% of their recorded locations. The article also noted that sea-surface temperature during the capture period ranged from 27.1°C to 29.4°C. It did not report turtle mass or carapace length.
According to the passage, which of the following is true?
Answer: The tags were programmed to transmit location data every 6 hours.
This question tests detail comprehension by asking which statement is true according to the passage. Correct answers in such questions restate explicit information from the text without adding inferences or external knowledge. The relevant detail is in the second sentence, which describes the satellite tags. This sentence states that the tags were programmed to transmit location data every 6 hours. Choice A matches this text by restating the transmission frequency. A representative distractor, like choice C, fails because it claims the study reported turtle mass and carapace length, but the passage explicitly notes that it did not report these measurements. This distractor contradicts a direct statement.

A literary journal article compared two annotated editions of a 17th-century play. Edition R, published in 1998, included 214 footnotes and a 36-page introduction. Edition S, published in 2016, included 287 footnotes and a 22-page introduction. The article stated that both editions modernized spelling in the main text but retained original punctuation in stage directions. It also noted that Edition S added a glossary of 140 terms, while Edition R did not include a glossary. The author of the article observed that Edition R's notes more frequently cited contemporary pamphlets, but the article did not provide counts of those citations.
Which of the following is mentioned in the passage?
Answer: Edition S included 287 footnotes.
This question tests detail comprehension by asking which statement is mentioned in the passage. Correct answers in such questions restate explicit information from the text without adding inferences or external knowledge. The relevant detail is in the third sentence, which compares the footnotes in the editions. This sentence states that Edition S included 287 footnotes. Choice B matches this text by identifying Edition S and the exact footnote count. A representative distractor, like choice D, fails because it claims the article provided exact counts of pamphlet citations, but the passage notes only that Edition R cited them more frequently without providing counts. This distractor adds unstated specifics.

In a 2019 study of urban heat mitigation, researchers evaluated 24 municipal "cool roof" pilot projects across three U.S. cities: Phoenix, Chicago, and Baltimore. The projects were implemented between May 2016 and September 2018 and focused on coating existing flat rooftops with a white acrylic membrane. The passage notes that the Phoenix cohort included 10 buildings, Chicago included 8, and Baltimore included 6, for a total of 24. Roof surface temperatures were measured with infrared sensors installed at each site, and indoor air temperatures were recorded in a subset of buildings that had functioning HVAC data loggers. The researchers report that the coating increased average roof reflectance from 0.18 to 0.67 when measured one month after installation. They also state that two Baltimore sites were excluded from the indoor-temperature analysis because their data loggers failed during July 2017. For cost accounting, labor and materials were tracked separately; the passage specifies that the median installed cost was $18.50 per square meter in Phoenix and $21.00 per square meter in Chicago, while Baltimore's median cost was not reported because invoices were incomplete for three buildings.
According to the passage, which of the following is true?
Answer: The projects were implemented between May 2016 and September 2018.
This question tests the ability to identify specific details explicitly stated in the passage. The correct answer must restate information that appears directly in the text without requiring inference or interpretation. The passage explicitly states in the second sentence that "The projects were implemented between May 2016 and September 2018," making option B the correct answer. This exact timeframe is provided as a factual detail about when the cool roof pilot projects took place. Option A is incorrect because the passage states Baltimore's median cost "was not reported because invoices were incomplete for three buildings," contradicting the claim that it was reported as $21.00 per square meter.

A psychology study tested whether background music affects proofreading accuracy. The researchers recruited 180 participants and randomly assigned them to one of three conditions: silence, instrumental music at 60 decibels, or instrumental music at 75 decibels. Each participant proofread the same 800-word passage containing exactly 24 intentional errors (spelling, punctuation, and subject-verb agreement). Participants had 12 minutes to mark errors. The study reported mean numbers of errors correctly identified as 16.8 (silence), 15.9 (60 dB), and 14.7 (75 dB). The authors stated that participants wore identical over-ear headphones in both music conditions. They also reported that the experiment was conducted in a single laboratory room over four consecutive afternoons.
According to the passage, which of the following is true?
Answer: Participants proofread an 800-word passage containing exactly 24 intentional errors.
This question tests detail comprehension by asking which statement is true according to the passage. Correct answers in such questions restate explicit information from the text without adding inferences or external knowledge. The relevant detail is in the third sentence, which describes the proofreading task. This sentence specifies that each participant proofread the same 800-word passage containing exactly 24 intentional errors. Choice A matches this text by restating the word count and the exact number of errors. A representative distractor, such as choice D, fails because it misattributes the highest mean to the 75 dB condition, whereas the passage reports the highest (16.8) for silence and the lowest (14.7) for 75 dB. This distractor confuses the order of results.
