Hidden premise: Driving behavior is similar across cities. Which of the following, if true, most seriously weakens the economist’s argument?
A Rationale: Self-selection (motivated managers) could cause higher ratings regardless of training, explaining the observational study’s effect. Random assignment removes this bias. B would reduce difference, not explain it. C contradicts timeline. D is possible but less direct — and the study claimed no significant difference, not just power issue. E suggests industry difference, but A resolves via selection bias, the classic explanation for observational vs. RCT discrepancy. Passage 3 (Weaken — Expert Level) Economist: In order to reduce traffic congestion, the city council plans to impose a $15 daily congestion charge for driving into the downtown zone between 7 AM and 7 PM. Based on a pilot study in a similar city, such a charge reduced traffic by 18% within six months. Therefore, the plan will likely succeed here. utopia verbal critical reasoning test (expert)
A) Confuses a change in proportion with a change in absolute numbers. B) Assumes that public defender funding is the only factor affecting conviction rates. C) Relies on anecdotal evidence about individual cases. D) Fails to consider that conviction rates might have risen even more without the funding. E) Takes a correlation between two trends as proof of causation. Hidden premise: Driving behavior is similar across cities
A) The similar city had a robust public transit system, while this city’s transit is unreliable and underfunded. B) In the similar city, 40% of commuters switched to biking, which is not feasible in this city due to weather. C) The $15 charge would represent a smaller percentage of average income in this city than in the similar city. D) Traffic congestion in this city is 25% worse than in the similar city at the start of the pilot. E) Some drivers in the similar city began using alternative routes, not reducing overall city congestion. Random assignment removes this bias
A Rationale: The argument’s hidden assumption is that the causal mechanism (charge → less driving) transfers. A attacks the mechanism: without good transit, drivers have no alternative, so reduction may not occur. B is similar but narrower (biking only). C weakens (charge less effective) but less direct than A, which eliminates alternatives entirely. D and E are irrelevant or weaken less. Passage 4 (Principle Application) Principle: An action is morally permissible only if it does not treat another person merely as a means to an end, and it respects their capacity for rational consent.

Principle Application | | Scoring | 0–900 scaled (600+ = expert level) | Instructions (as seen by candidate) Each question presents a short passage followed by a critical reasoning task. Do not use outside knowledge. The passage is the sole source of truth. Pay attention to quantifiers (some, most, all, none), modals (must, may, could), and embedded exceptions . For "Weaken" questions, select the option that, if true , most undermines the core logical link — not merely the conclusion’s plausibility. For "Must Be True", the answer must be provable directly from the passage without additional assumptions. Sample Test Module (Expert Level) Passage 1 (Inference & Flaw) Despite increased funding for public defense attorneys in the state of Caledonia, conviction rates among indigent defendants have risen by 8% over the last three years. The governor claims that this proves the additional funding was wasted, since more poor defendants are being found guilty. However, the state’s chief public defender notes that during the same period, overall crime rates fell by 12%, and the number of cases brought against indigent defendants dropped by 15%. She argues that the remaining cases are more serious on average, and therefore harder to win, making the funding justified. Question 1 (Must Be True) Which of the following can be correctly inferred from the passage?
The governor’s reasoning is most vulnerable to criticism because it:
