LSAT Logical Reasoning: Paradox and Explain Questions

Question 1

Studies show that countries with more hospitals per capita have higher mortality rates from heart disease than countries with fewer hospitals.
Which of the following most helps to explain this apparently paradoxical result?

Accepted Answer

Countries with higher rates of heart disease invest more in hospital infrastructure to treat the problem.

Answer

Heart disease treatments have improved significantly in recent decades.

Answer

Hospitals are more expensive to operate in developed countries.

Answer

Heart disease affects people of all ages and demographic groups.

Answer

Medical training standards vary significantly across countries.

Question 2

In a city that implemented a major public transit expansion, traffic congestion on highways actually increased in the years following the expansion. Which of the following, if true, most helps to explain this result?

Accepted Answer

New residents and businesses relocated to the city specifically because of the improved transit system, adding more vehicles overall than the transit took off roads.

Answer

The transit expansion cost significantly more than originally projected.

Answer

Some transit routes overlapped with existing bus lines, creating redundancy.

Answer

Transit fares were higher than in neighboring cities.

Answer

Construction for the transit system temporarily closed several highway lanes.

Question 3

A company implemented a rigorous training program for its customer service representatives. After the program, customer satisfaction scores dropped significantly. Which of the following most helps to explain this paradox?

Accepted Answer

The training took representatives away from their desks for several weeks, causing longer wait times that frustrated customers.

Answer

The training program covered topics not directly related to customer service.

Answer

The company simultaneously raised prices for its services.

Answer

Some representatives left the company immediately following the training program.

Answer

The training materials were developed by an outside consulting firm.

Question 4

A study found that neighborhoods with more police patrols have higher crime rates than neighborhoods with fewer police patrols. Which of the following most helps to explain this finding without concluding that police patrols cause crime?

Accepted Answer

Law enforcement agencies deploy more patrols to areas that already have higher crime rates, so patrol density is a response to crime, not a cause.

Answer

Police officers are more effective when they work in teams.

Answer

Some police officers engage in misconduct that alienates community members.

Answer

Patrolled neighborhoods tend to have more businesses, which are common targets of theft.

Answer

Citizens in patrolled neighborhoods are more likely to report crimes to authorities.

Question 5

Patients at teaching hospitals, where medical students and residents receive training, have been found to have lower mortality rates than patients at non-teaching hospitals, despite the fact that less experienced practitioners perform many procedures at teaching hospitals. Which of the following most helps to explain this paradox?

Accepted Answer

Teaching hospitals attract senior specialists and have more comprehensive staffing, diagnostic resources, and oversight protocols than most community hospitals.

Answer

Teaching hospitals tend to be located in urban areas with better emergency transport.

Answer

Teaching hospitals are accredited by medical schools, which hold them to higher standards.

Answer

Medical students at teaching hospitals are particularly motivated to prove themselves.

Answer

Teaching hospitals treat a higher volume of patients, allowing staff to gain more experience.

Question 6

An electric utility implemented a conservation program offering rebates to customers who reduced electricity consumption. Total electricity consumption in the service area increased during the program year. Which of the following most helps to explain this paradox?

Accepted Answer

The rebate program attracted energy-intensive businesses to the service area due to lower effective electricity costs, adding more consumption than the program saved.

Answer

The rebate amounts were too small to motivate most customers.

Answer

Utility customers are generally resistant to behavioral change programs.

Answer

Electricity prices increased during the program year due to fuel costs.

Answer

The program was not widely publicized to customers.

Question 7

People who take vitamin supplements regularly have been found to have higher rates of certain diseases than people who do not take supplements. This finding seems to contradict the purpose of taking supplements. Which of the following most helps to explain this paradox?

Accepted Answer

People who feel unwell or at risk for disease are more likely to begin taking supplements in response to health concerns, creating a reverse-causation effect.

Answer

Vitamin supplements are manufactured using a variety of methods and vary in quality.

Answer

Some vitamins interact negatively with common medications.

Answer

The marketing of vitamin supplements misleads consumers about health benefits.

Answer

Supplement takers tend to be older and therefore more susceptible to disease.

Question 8

A city removed a heavily trafficked elevated highway and replaced it with a surface boulevard. Traffic engineers predicted severe congestion, but traffic volume in the surrounding area actually decreased after demolition. Which of the following most helps to explain this result?

Accepted Answer

Drivers who had been using the highway specifically because of its high capacity reduced their trips or changed to transit and other routes once the highway was gone, and total vehicle trips in the area declined.

Answer

The boulevard had fewer traffic lights than the elevated highway.

Answer

The construction period temporarily closed nearby streets, training drivers to use alternate routes.

Answer

The surface boulevard allowed commercial development that replaced commuter trips with local activity.

Answer

Local businesses near the demolished highway lobbied against the replacement.

Question 9

A school district increased spending per student significantly over a decade, yet standardized test scores remained flat. Which of the following most helps to explain why increased spending did not improve test scores?

Accepted Answer

The additional funds were directed primarily toward administrative costs, facility maintenance, and special programs rather than instructional improvements.

Answer

Standardized tests are not considered accurate measures of academic achievement.

Answer

Teachers in the district received below-average salaries compared to neighboring districts.

Answer

The student population remained constant throughout the decade.

Answer

Test score improvements typically take more than a decade to appear.

Question 10

A national campaign to reduce smoking through graphic warning labels on cigarette packages was followed by an increase in cigarette sales among teenage smokers. Which of the following most helps to explain this paradox?

Accepted Answer

The campaign raised the visibility and cultural prominence of smoking, making it appear more common and therefore more socially acceptable among teenagers who are influenced by perceived peer norms.

Answer

Graphic warning labels required more expensive printing processes, increasing cigarette costs.

Answer

The campaign received extensive media coverage that described the health risks in detail.

Answer

Tobacco companies increased advertising expenditures in response to the campaign.

Answer

Some teenagers have not yet developed the ability to assess long-term health risks.
