A district adopts a four-day school week and reports improved attendance. It concludes that the shorter week benefits students. Attendance may rise simply because there are fewer school days on which absence can occur. Longer school days may also increase fatigue, while families may face childcare costs on the fifth day. Rural districts with long travel times may experience different effects from urban districts. The district should compare attendance rates rather than raw absence counts, examine learning time and outcomes, and track effects across age, disability, income, and location. A schedule should be judged by the full pattern of learning and access it creates, not by one improved number whose denominator has changed.
Travel and access conditions may produce different effects.
Only rural students learn.
Urban schools have no schedules.
Location eliminates fatigue.
Correct answer: A. Travel and access conditions may produce different effects.
A follows from the second paragraph.

A city removes more waste from one stretch of river each year and describes the cleanup as an environmental success. Collection totals show effort, but rising totals may indicate that more waste is entering upstream. Cleanup can improve a local site while moving disposal burdens elsewhere. Waste taken from water must be sorted and safely processed, or pollution may shift from river to land. The city should measure inflow, water quality, sources, recurrence, disposal, and downstream conditions. It should combine removal with prevention such as better collection systems and controls on dumping. Success means reducing the pollution cycle, not merely increasing the quantity repeatedly removed from one visible location.
Waste removal has no value.
Cleanup success requires prevention and system-wide pollution reduction.
Collected waste should return to water.
Only visible sites matter.
Correct answer: B. Cleanup success requires prevention and system-wide pollution reduction.
B captures the systemic conclusion.

A university uses an automated detector to flag possible plagiarism. It reports high accuracy on test documents and proposes treating every flag as proof of misconduct. Accuracy alone is insufficient. If plagiarism is rare, even a modest false-positive rate can produce many innocent flags. Writing style, quoted material, and language background may also affect results. Flags should trigger human review, access to the underlying evidence, and an opportunity for the student to respond. The university should publish error rates across groups and audit outcomes. An automated system can help direct attention. It should not convert a prediction into a finding without a fair process.
Every flag proves misconduct.
Automated review should replace evidence.
Detector flags require evidence-based human review and fair process.
Accuracy has no value.
Correct answer: C. Detector flags require evidence-based human review and fair process.
C captures the central conclusion.
Source note: Original LexMentor CLAT UG Batch 23, prepared in the official passage-based format.
Rare misconduct may mean innocent flags form a large share of all flags.
Every document is plagiarised.
False positives increase true misconduct.
Accuracy cannot be calculated.
Correct answer: B. Every document is plagiarised.
B states the base-rate concern.

A city repairs roads according to the number of complaints received through an app. Officials argue that the most complained-about roads must be the most damaged. Complaint volume reflects damage, but also phone access, awareness, language, time, and confidence that reporting will matter. A severely damaged road in a low-reporting area may receive little attention. The city should combine complaints with inspections, transport usage, safety risk, and offline reporting. It should also publish how priorities are set. Citizen reports are valuable signals. Treating their absence as proof that no problem exists turns unequal reporting access into unequal public maintenance.
Complaints should be ignored.
Apps measure damage perfectly.
Only busy roads require repair.
Road priorities should combine reports with inspection, risk, and access considerations.
Correct answer: D. Road priorities should combine reports with inspection, risk, and access considerations.
D captures the proposed broader method.

Complaint volume tracks damage similarly across areas with different reporting access.
Every road receives an inspection.
Offline reports are already counted.
Phone access is universal by law.
Correct answer: A. Complaint volume tracks damage similarly across areas with different reporting access.
A is required for complaint counts to compare damage fairly.

App users receive confirmation.
Inspections find severe damage in neighbourhoods with few smartphones and few complaints.
Some users attach photographs.
Complaints contain dates.
Correct answer: B. Inspections find severe damage in neighbourhoods with few smartphones and few complaints.

A city installs noise sensors and finds that one district records fewer complaints than another despite higher measured sound. Officials conclude that residents there are less disturbed. Complaint rates depend on awareness, trust, language, time, and access to reporting. People may also stop complaining when earlier reports produced no response. Sensors add objective information but do not measure sleep loss, stress, or the social meaning of different sounds. The city should combine measurements, surveys, health data, and accessible complaint channels. Silence in administrative records is not necessarily evidence of comfort. It may reveal that experience and reporting have become disconnected.
Low complaint counts do not alone show low disturbance.
Sensors should be removed.
Sound can never be measured.
Every district experiences noise identically.
Correct answer: A. Low complaint counts do not alone show low disturbance.
A captures the central warning.

A government releases free digital textbooks and reports millions of downloads. It treats the total as proof that access and learning have improved. A download may represent repeated attempts, automated traffic, or a file never opened. Learners may lack suitable devices, storage, electricity, or accessible formats. Downloads remain useful for measuring distribution. To assess access and learning, officials should examine unique users, successful opening, reading patterns, disability access, offline availability, and educational outcomes. Distribution is a necessary step, but counting delivery events is not the same as measuring whether a resource can be used effectively.
Digital textbooks have no value.
Download totals alone do not establish effective access or learning.
Every download represents study.
Devices are universally available.
Correct answer: B. Download totals alone do not establish effective access or learning.
B captures the central distinction.
