Passage or principleOriginal argumentative passage

A firm claims that its four-day workweek increased productivity because weekly output rose during a three-month trial. The result is promising, but the firm also introduced new software, hired two experienced employees, and postponed its least profitable projects during the same period. The trial should therefore not be treated as conclusive proof. Output per employee-hour, error rates, customer delays, and staff well-being should be compared with an appropriate earlier period. The firm should also examine whether employees compressed work into longer days or completed tasks during unofficial hours. None of these cautions proves that a shorter week failed. They show why a single rise in total output cannot identify its cause. A longer trial with transparent measures would better support a decision about permanent adoption.

Question 72HardFour-Day Workweek Evidence

What is the principal weakness in the firm's claim?

  1. A

    It ignores other simultaneous changes that could have increased output.

  2. B

    It measures output over more than one day.

  3. C

    It assumes that employees use software.

  4. D

    It compares workers within the same firm.

View answer and explanation

Correct answer: A. It ignores other simultaneous changes that could have increased output.

A identifies the confounding changes that prevent a clear causal inference.

Question 73MediumFour-Day Workweek Evidence

Which finding would most strengthen the claim that the shorter week caused the improvement?

  1. A

    Output rose only after experienced employees joined.

  2. B

    Most postponed projects required little work.

  3. C

    Comparable teams without shorter weeks showed no gain, while trial teams improved without extra unpaid hours.

  4. D

    Customers reported longer delays throughout the trial.

View answer and explanation

Correct answer: C. Comparable teams without shorter weeks showed no gain, while trial teams improved without extra unpaid hours.

C supplies a useful comparison and addresses hidden working time.

Question 74HardFour-Day Workweek Evidence

Which finding would most weaken the firm's claim?

  1. A

    Employees preferred having an additional day away from the office.

  2. B

    The trial lasted three months.

  3. C

    Weekly output can be counted in units.

  4. D

    Most of the output gain came from the new hires, while error rates increased.

View answer and explanation

Correct answer: D. Most of the output gain came from the new hires, while error rates increased.

D gives an alternative cause and evidence of a quality cost.

Question 75MediumFour-Day Workweek Evidence

Why should unofficial working hours be measured?

  1. A

    They determine whether apparently maintained output was achieved by shifting work outside recorded hours.

  2. B

    They prove that longer days are always unlawful.

  3. C

    They eliminate the need to measure errors.

  4. D

    They show whether new software was purchased.

View answer and explanation

Correct answer: A. They determine whether apparently maintained output was achieved by shifting work outside recorded hours.

A explains how hidden hours could distort the apparent productivity result.

Passage or principleOriginal argumentative passage

A university proposes giving students automated summaries of every assigned article. Supporters argue that summaries will help students identify key ideas before class. Critics respond that students will stop reading the articles themselves. Both predictions are possible. A summary can provide orientation, especially when a text introduces unfamiliar terms. It can also flatten uncertainty, omit evidence, and make a contested argument appear settled. Its effect depends partly on how a course uses it. The university should test summaries as guides rather than substitutes. Students might compare each summary with selected passages, identify omissions, and cite the original text in assignments. The pilot should measure comprehension and source use, not merely whether students say the tool is convenient. The relevant choice is therefore not simply between permitting and banning summaries. It is between designs that encourage return to the source and designs that reward avoidance of it.

Question 76MediumAI Summaries and Source Reading

Which statement best expresses the author's conclusion?

  1. A

    Automated summaries should replace assigned readings.

  2. B

    Student convenience is a complete measure of learning.

  3. C

    Summaries should be tested in a design that directs students back to original sources.

  4. D

    Every automated summary necessarily contains false information.

View answer and explanation

Correct answer: C. Summaries should be tested in a design that directs students back to original sources.

C states the passage's central recommendation.

Source note: Original LexMentor CLAT UG Batch 8, prepared in the official passage-based format.

Question 77HardAI Summaries and Source Reading

The proposed comparison exercise assumes that:

  1. A

    Students can learn something by detecting differences between a summary and its source.

  2. B

    Original articles never contain uncertainty.

  3. C

    Every student already understands unfamiliar terms.

  4. D

    Convenient tools always improve comprehension.

View answer and explanation

Correct answer: A. Students can learn something by detecting differences between a summary and its source.

A is required for source comparison to have educational value.

Source note: Original LexMentor CLAT UG Batch 8, prepared in the official passage-based format.

Question 78MediumAI Summaries and Source Reading

Which result would most strengthen the author's proposed approach?

  1. A

    Students using summaries stop opening assigned articles.

  2. B

    Students who compare summaries with sources identify more evidence and cite the articles more accurately.

  3. C

    Students rate the interface as attractive.

  4. D

    The summaries become shorter each week.

View answer and explanation

Correct answer: B. Students who compare summaries with sources identify more evidence and cite the articles more accurately.

B directly supports the claimed educational value of guided comparison.

Source note: Original LexMentor CLAT UG Batch 8, prepared in the official passage-based format.

Question 79HardAI Summaries and Source Reading

Which finding would most weaken the claim that summaries provide useful orientation?

  1. A

    The articles contain technical terms.

  2. B

    Students have different levels of prior knowledge.

  3. C

    Assignments require citation of original texts.

  4. D

    Summaries regularly misstate central claims and create confusion that persists after reading.

View answer and explanation

Correct answer: D. Summaries regularly misstate central claims and create confusion that persists after reading.

D shows that the summaries obstruct rather than support understanding.

Source note: Original LexMentor CLAT UG Batch 8, prepared in the official passage-based format.

Question 80MediumAI Summaries and Source Reading

Which statement follows most strongly from the passage?

  1. A

    The educational effect of a tool depends partly on the tasks and incentives surrounding its use.

  2. B

    Any use of summaries amounts to academic misconduct.

  3. C

    Source reading is unnecessary when comprehension is measured.

  4. D

    Banning technology is the author's preferred solution.

View answer and explanation

Correct answer: A. The educational effect of a tool depends partly on the tasks and incentives surrounding its use.

A follows from the contrast between designs that encourage or discourage source use.

Passage or principleOriginal argumentative passage

A city plans to allocate patrols using a system trained on past arrest records. Officials argue that more arrests in an area prove that more crime occurs there. The inference is incomplete because arrest records reflect both offending and earlier enforcement choices. Areas receiving more patrols may generate more recorded incidents even when underlying crime rates are similar. Feeding those records back into the system can repeatedly direct attention to the same places. This does not prove that every geographic pattern is false, but it means arrest counts cannot validate the system by themselves. Before deployment, the city should compare multiple sources, test for feedback effects, publish error measures, and examine whether additional patrols improve safety rather than merely increase recorded enforcement.

Question 81MediumPredictive Policing and Historical Data

Which statement best expresses the author's conclusion?

  1. A

    Historical arrest data require independent testing before they guide patrol allocation.

  2. B

    Every geographic crime pattern is false.

  3. C

    More arrests always prove greater safety.

  4. D

    Past enforcement choices have no effect on records.

View answer and explanation

Correct answer: A. Historical arrest data require independent testing before they guide patrol allocation.

A captures the passage's qualified recommendation.

Source note: Original LexMentor CLAT UG Batch 9, prepared in the official passage-based format.

Question 82HardPredictive Policing and Historical Data

What is the flaw in treating arrest counts as a direct measure of crime?

  1. A

    Arrests can never be counted accurately.

  2. B

    Cities do not allocate patrols.

  3. C

    The counts may partly result from where enforcement was already concentrated.

  4. D

    Crime is identical in every area.

View answer and explanation

Correct answer: C. The counts may partly result from where enforcement was already concentrated.

C identifies enforcement intensity as an alternative explanation.

Source note: Original LexMentor CLAT UG Batch 9, prepared in the official passage-based format.

Question 83HardPredictive Policing and Historical Data

What feedback effect concerns the author?

  1. A

    Patrols reduce the amount of historical data.

  2. B

    More patrols produce more records, which then justify sending still more patrols.

  3. C

    Residents automatically move when patrols arrive.

  4. D

    Published error measures increase crime.

View answer and explanation

Correct answer: B. More patrols produce more records, which then justify sending still more patrols.

B states the self-reinforcing cycle described in the passage.

Source note: Original LexMentor CLAT UG Batch 9, prepared in the official passage-based format.

Question 84MediumPredictive Policing and Historical Data

Which finding would most strengthen the case for deployment?

  1. A

    The system reproduces last year's arrest map exactly.

  2. B

    Officials prefer automated decisions.

  3. C

    Arrest totals rise wherever patrols increase.

  4. D

    Independent victimisation data confirm the pattern, and deployment reduces serious harm without unequal error rates.

View answer and explanation

Correct answer: D. Independent victimisation data confirm the pattern, and deployment reduces serious harm without unequal error rates.

D provides independent validation and evidence of improved safety.

Source note: Original LexMentor CLAT UG Batch 9, prepared in the official passage-based format.

Question 85MediumPredictive Policing and Historical Data

Why should the city measure safety rather than arrests alone?

  1. A

    An increase in enforcement records may occur without an equivalent improvement in safety.

  2. B

    Safety can never be measured.

  3. C

    Arrests are unrelated to police activity.

  4. D

    Only published data can reduce crime.

View answer and explanation

Correct answer: A. An increase in enforcement records may occur without an equivalent improvement in safety.

A reflects the passage's distinction between recorded enforcement and public safety.

Passage or principleOriginal argumentative passage

A municipal programme celebrates the number of trees planted each monsoon. Planting totals are easy to announce, but they do not show whether trees survive, provide shade, or improve neighbourhoods that lack green cover. Young trees may fail because species are poorly matched to soil, roots lack space, or watering ends after the launch event. Survival can also vary across neighbourhoods. A citywide average may conceal repeated failure in hotter and less-resourced areas. The programme should report survival after one, three, and five years, canopy growth, maintenance spending, and geographic distribution. These measures may produce less impressive headlines than planting counts, but they better reflect durable public value. The criticism is not an argument against planting. It is an argument for defining success by outcomes that the initial act of planting is meant to achieve.

Question 86MediumUrban Tree Planting and Survival

Which statement best expresses the author's conclusion?

  1. A

    Tree planting should end in all cities.

  2. B

    Only maintenance spending matters.

  3. C

    Every planted tree produces equal public value.

  4. D

    Tree programmes should be judged by survival, distribution, and lasting benefits.

View answer and explanation

Correct answer: D. Tree programmes should be judged by survival, distribution, and lasting benefits.

D captures the outcome-based standard proposed by the author.

Source note: Original LexMentor CLAT UG Batch 9, prepared in the official passage-based format.

Question 87MediumUrban Tree Planting and Survival

Why may a citywide survival average be misleading?

  1. A

    It contains too many time periods.

  2. B

    It may hide much lower survival in particular neighbourhoods.

  3. C

    It measures trees rather than roads.

  4. D

    It always understates total planting.

View answer and explanation

Correct answer: B. It may hide much lower survival in particular neighbourhoods.

B follows directly from the second paragraph.

Source note: Original LexMentor CLAT UG Batch 9, prepared in the official passage-based format.

Question 88HardUrban Tree Planting and Survival

Which finding would most strengthen the author's criticism of planting totals?

  1. A

    Most trees counted at launch die within two years in the least shaded areas.

  2. B

    The mayor attends the planting event.

  3. C

    The city publishes the number of volunteers.

  4. D

    Monsoon rainfall varies from week to week.

View answer and explanation

Correct answer: A. Most trees counted at launch die within two years in the least shaded areas.

A directly shows that initial counts overstate durable and equitable value.

Source note: Original LexMentor CLAT UG Batch 9, prepared in the official passage-based format.

Question 89HardUrban Tree Planting and Survival

Which finding would most weaken the claim that planting totals are inadequate in this programme?

  1. A

    Tree species differ across locations.

  2. B

    Some neighbourhoods are hotter than others.

  3. C

    The published planting count includes only trees independently verified to survive five years and records their canopy and location.

  4. D

    The programme uses a public logo.

View answer and explanation

Correct answer: C. The published planting count includes only trees independently verified to survive five years and records their canopy and location.

C shows that the reported count already incorporates the outcome measures demanded.

Source note: Original LexMentor CLAT UG Batch 9, prepared in the official passage-based format.

Question 90MediumUrban Tree Planting and Survival

How does the final paragraph function?

  1. A

    It withdraws the earlier criticism.

  2. B

    It claims that outcomes cannot be measured.

  3. C

    It recommends planting without maintenance.

  4. D

    It distinguishes criticism of the programme's metric from opposition to planting itself.

View answer and explanation

Correct answer: D. It distinguishes criticism of the programme's metric from opposition to planting itself.

D states the clarification made in the final paragraph.

Passage or principleOriginal argumentative passage

A school proposes installing cameras in every classroom to improve teaching quality. Administrators argue that recorded lessons will reveal effective methods. Teachers respond that constant recording may change behaviour and discourage students from asking uncertain questions. Both claims require evidence. A recording can support review, but the presence of a camera may alter the activity being studied. Administrators may also select only easily measured features, such as how often a teacher speaks, while overlooking whether students understand. The school should first run a limited, consent-based pilot. It should specify who may view recordings, how long files remain stored, and which educational outcomes will be assessed. Comparison with similar unrecorded classes would help separate camera effects from ordinary variation. The question is not whether observation is always useful or always harmful, but whether this system produces reliable improvement at an acceptable cost to privacy and participation.

Question 91MediumClassroom Cameras and Evidence

Which statement best expresses the author's conclusion?

  1. A

    The school should test the camera system against learning, privacy, and participation outcomes before wider use.

  2. B

    Cameras always improve teaching.

  3. C

    Teacher speaking time fully measures learning.

  4. D

    Classroom observation should be prohibited.

View answer and explanation

Correct answer: A. The school should test the camera system against learning, privacy, and participation outcomes before wider use.

A captures the author's conditional evaluation.

Why may recordings provide distorted evidence?

  1. A

    Students never enter recorded rooms.

  2. B

    Video cannot show a classroom.

  3. C

    The camera itself may change the behaviour being observed.

  4. D

    All teachers use identical methods.

View answer and explanation

Correct answer: C. The camera itself may change the behaviour being observed.

C states the observation effect identified in the second paragraph.

Source note: Original LexMentor CLAT UG Batch 10, prepared in the official passage-based format.

Question 93MediumClassroom Cameras and Evidence

Which finding would most strengthen the case for wider use?

  1. A

    Administrators enjoy watching recordings.

  2. B

    Pilot classes show independently measured learning gains without reduced participation or privacy breaches.

  3. C

    Recorded files are kept indefinitely.

  4. D

    Teachers speak more often when observed.

View answer and explanation

Correct answer: B. Pilot classes show independently measured learning gains without reduced participation or privacy breaches.

B supplies evidence on the outcomes and risks emphasised by the author.

Question 94HardClassroom Cameras and Evidence

Which finding would most weaken the proposal?

  1. A

    The school already owns computers.

  2. B

    Some lessons last forty minutes.

  3. C

    Administrators can count teacher statements.

  4. D

    Students in recorded classes ask fewer questions and show no learning improvement.

View answer and explanation

Correct answer: D. Students in recorded classes ask fewer questions and show no learning improvement.

D shows a participation cost without the claimed educational benefit.

Source note: Original LexMentor CLAT UG Batch 10, prepared in the official passage-based format.

Question 95MediumClassroom Cameras and Evidence

Why compare recorded classes with similar unrecorded classes?

  1. A

    To estimate whether observed changes result from cameras rather than ordinary variation

  2. B

    To guarantee that both groups receive identical marks

  3. C

    To remove the need for consent

  4. D

    To measure only file-storage costs

View answer and explanation
