Critical Reasoning Evaluate Mock Tests

A city council is considering whether to ban private cars from the downtown area and replace parking lots with pedestrian plazas. Supporters argue that cities in Europe, such as Amsterdam and Copenhagen, have successfully reduced car traffic and created vibrant downtowns. Opponents counter that downtown residents in this city rely heavily on cars because public transportation is inadequate. Which of the following would be most useful to determine in order to evaluate the opponents' objection?

A city planner proposes replacing all public bus routes with on-demand ride-sharing services. The plan argues that ride-sharing is more efficient because it eliminates the waste of running empty buses along fixed routes. The planner concludes that this change will reduce transportation costs by at least thirty percent. Which of the following would be most useful to determine in order to evaluate the planner's conclusion?

A company implemented a four-day workweek experiment with 200 employees. At the end of the trial, employee satisfaction scores increased by 25%, and the company's total output remained unchanged compared to the previous five-day week. The CEO announces that the four-day workweek will become permanent policy across all departments. Which of the following, if true, would most help evaluate whether the CEO's decision will achieve its intended effect?

A pharmaceutical company conducted a clinical trial of a new drug designed to lower blood pressure. The trial involved 500 participants, and results showed that 80% of those who took the drug experienced a significant reduction in blood pressure. The company concluded that the drug is highly effective and should be approved for widespread use. Which of the following, if true, would most help evaluate the company's conclusion?

The city council voted 5-4 to approve the new zoning regulations, which will allow for higher-density development in areas previously restricted to single-family homes. Supporters of the measure argued that the city's housing shortage could only be addressed by increasing the supply of housing units. Opponents contended that the change would strain existing infrastructure and alter the character of established neighbourhoods. Environmental groups, however, pointed out that higher-density housing reduces urban sprawl and can lower per-capita carbon emissions, suggesting that the opposition's concerns, while understandable, may overlook the broader environmental benefits of densification. The primary purpose of the environmental groups' argument is to:

A study of university students found that those who attended office hours at least once per month earned, on average, one full letter grade higher than students who never attended office hours. A university administrator concluded that encouraging all students to attend office hours would significantly improve academic performance across the student body. Which of the following would be most useful to determine in order to evaluate the administrator's conclusion?

A pharmaceutical researcher claims that a new drug reduces blood pressure more effectively than the current standard treatment. To support this claim, the researcher cites a study in which participants who took the new drug experienced an average reduction of 15 mmHg, compared to 10 mmHg for those on the standard treatment. The study was funded by the drug's manufacturer. Which of the following, if true, would be most useful in evaluating the researcher's claim?

A study found that neighborhoods with higher tree canopy cover had lower average temperatures and lower asthma rates among residents. Based on these findings, a public health official recommends planting more trees in neighborhoods with high asthma rates to reduce respiratory illnesses. Which of the following, if true, most helps evaluate whether this recommendation will achieve its intended effect?
