LSAT Practice Questions - Law School Admission Test Exam - LSAT Practice Questions

Question 1

The city council recently enacted a ban on single-use plastic bags. The council claimed the ban would significantly reduce litter in local waterways. However, studies in cities with similar bans show that plastic bag litter in waterways decreased by only 3% while overall litter increased as residents switched to heavier plastic bags that are equally problematic. Which of the following, if true, most seriously weakens the council's claim?

Some residents have begun using reusable cloth bags since the ban took effect. The 3% reduction in plastic bag litter represents tens of thousands of bags annually. Heavier plastic bags fragment into microplastics at a faster rate than single-use bags in aquatic environments. The city council consulted environmental experts before enacting the ban.

Correct Answer:

Heavier plastic bags fragment into microplastics at a faster rate than single-use bags in aquatic environments.

Question 2

All professional athletes who compete in contact sports experience some degree of concussion risk. Anyone who experiences concussion risk should undergo regular neurological screening. Therefore, all professional athletes who compete in contact sports should undergo regular neurological screening. The argument above is an example of which of the following reasoning patterns?

Concluding that because two things share one property, they share all properties. Applying a general principle to a specific case that falls within its scope. Drawing a statistical generalization from a sample to a larger population. Assuming that what is true of the parts of a whole is true of the whole.

Correct Answer:

Applying a general principle to a specific case that falls within its scope.

Question 3

Historian: The decline of the Roman Empire cannot be attributed primarily to military overextension. While the empire did maintain a large military, records show that military spending as a proportion of GDP remained relatively stable for two centuries before the fall. Economic disruption caused by currency debasement is a far more plausible primary cause. Which of the following is an assumption required by the historian's argument?

Currency debasement had a greater economic impact than any military factor. Stable military spending as a proportion of GDP indicates that military overextension was not a primary cause of decline. The Roman Empire's GDP remained constant during the two centuries before its fall. Military overextension is never a significant factor in the decline of empires.

Correct Answer:

Stable military spending as a proportion of GDP indicates that military overextension was not a primary cause of decline.

Question 4

The new municipal recycling program requires residents to separate recyclables into five distinct categories. City officials project the program will increase recycling rates by 40%. Critics argue the program will actually decrease overall recycling because the complexity will discourage participation. Which of the following, if true, most strongly supports the critics' position?

A neighboring city uses a single-stream recycling program and has a 60% recycling rate. Studies show that increasing the number of sorting categories required correlates with decreased household participation in recycling programs. The new program was developed with input from environmental groups. Residents who do participate in the new program will recycle a larger volume of materials than under the old system.

Correct Answer:

Studies show that increasing the number of sorting categories required correlates with decreased household participation in recycling programs.

Question 5

Scientist: Our research team conducted a double-blind study showing that patients who took the new medication experienced a 30% improvement in symptoms compared to those who took a placebo. Some colleagues have questioned whether the improvement is clinically meaningful, but a 30% improvement is substantial by any measure. The scientist's argument is most vulnerable to criticism on which of the following grounds?

The scientist fails to specify the sample size of the study. The scientist assumes that statistical significance guarantees clinical significance without establishing what threshold constitutes clinical meaningfulness. The scientist ignores the possibility that the placebo group's condition may have worsened. The scientist does not account for the cost of the new medication.

Correct Answer:

The scientist assumes that statistical significance guarantees clinical significance without establishing what threshold constitutes clinical meaningfulness.
