LSAT Practice Questions

The questions below are original practice items written for this guide. They are not copied from an LSAC test. The current LSAT tests Logical Reasoning and Reading Comprehension; it no longer includes Logic Games. Each question is followed by the correct answer and an explanation of every option so you can practice the reasoning rather than memorize a letter.

Try each item before reading its explanation. Mark a choice if you are unsure and record the time. Then review both wrong answers and correct guesses. The explanation should tell you what the stem asked, what the stimulus established, and how each distractor changes or misses the reasoning.

Question 1: Main conclusion

A public library extended its weekday hours for three months. Visits after 6 p.m. increased, and the number of visitors during the earlier afternoon remained about the same. The library board concludes that extending hours increased total community access to library services. Which choice best states the board's conclusion?

1. [object Object]
2. [object Object]
3. [object Object]
4. [object Object]
5. [object Object]

Answer: C. The conclusion is the claim the board draws from the reported visitor pattern. A is a premise, B is background about the change, D is an unsupported universal claim, and E is a new recommendation that the argument does not make. Notice that the conclusion could be identified even if you personally doubt whether the evidence proves it.

Question 2: Necessary assumption

The county plans to replace its streetlights with LED fixtures because the new fixtures use less electricity. The county expects the conversion to lower its total lighting costs. Which assumption is required for that expectation?

1. [object Object]
2. [object Object]
3. [object Object]
4. [object Object]
5. [object Object]

Answer: B. The conclusion concerns total cost, which includes more than electricity use. Negate B: the conversion costs more than the electricity savings during the relevant period. That undermines the prediction that total costs will fall. A is a preference unrelated to cost, C is not needed for the argument, D describes a feature but not its cost effect, and E could be helpful evidence but is not required if the county's own cost figures support the projection.

Question 3: Strengthen a causal claim

A clinic introduced appointment reminders by text. During the next quarter, missed appointments fell from 12 percent to 8 percent. The clinic concludes that the reminders caused the decline. Which fact most strengthens the conclusion?

1. [object Object]
2. [object Object]
3. [object Object]
4. [object Object]
5. [object Object]

Answer: C. A comparable clinic with no decline offers a control comparison, and stable patient volume reduces one alternative explanation. A weakens because the cancellation change may have caused the drop. B describes a potentially useful feature but does not show the reminders caused the result. D may matter to preference but not the measured decline. E is unrelated.

Question 4: Weaken a generalization

A student association surveyed 100 people who attended its campus meeting. Seventy said they support adding a weekday shuttle. The association concludes that most students at the university support the shuttle. Which fact most weakens the conclusion?

1. [object Object]
2. [object Object]
3. [object Object]
4. [object Object]
5. [object Object]

Answer: B. The argument generalizes from a self-selected and likely supportive subgroup to all students. B directly challenges representativeness. A could be relevant if location shaped responses, but the direct selection bias in B is stronger. C describes the proposal, D may affect response rates but does not tell us how the missing views differ, and E concerns a different service.

Question 5: Identify a flaw

Every permit approved for the festival included an emergency plan. This application includes an emergency plan. Therefore, the application will be approved. The reasoning is flawed because it

1. [object Object]
2. [object Object]
3. [object Object]
4. [object Object]
5. [object Object]

Answer: A. The rule is approved → plan. The argument observes a plan and infers approval, reversing the conditional. An application may need other information or may fail another criterion. B introduces timing that is not mentioned, C misstates the scope, D is not required for the conditional, and E contradicts the stated fact that the application includes a plan.

Question 6: Must be true

All boats stored in the harbor overnight have a numbered permit. No boat without a completed inspection may receive a numbered permit. Which statement must be true?

1. [object Object]
2. [object Object]
3. [object Object]
4. [object Object]
5. [object Object]

Answer: B. Overnight storage → numbered permit. The second rule says a numbered permit → completed inspection. Combining them gives overnight storage → inspection. A, D, and E reverse one of the conditional rules. C assumes that at least one boat is stored overnight, which the stimulus never states. B is the only answer that follows.

Question 7: Parallel reasoning

Every package delivered by the express service receives a tracking number. This package has a tracking number. Therefore, it was delivered by the express service. Which argument has the most similar reasoning?

1. [object Object]
2. [object Object]
3. [object Object]
4. [object Object]
5. [object Object]

Answer: C. The stimulus has the form express → tracking; tracking; therefore express. C has approved → income records; income records; therefore approved. Both reverse a sufficient condition. A and E use the conditional in a valid direction, B has a different inference, and D makes an unsupported overlap claim.

Questions 8 and 9: Reading Comprehension

Passage: “Some city planners argue that converting vacant lots into pocket parks improves neighborhood health by encouraging outdoor activity. A recent study found that residents living near new pocket parks reported more walking. The study did not measure activity before the parks opened, however, and the neighborhoods also received new sidewalks. Pocket parks may contribute to walking, but the evidence does not yet show whether the parks or the sidewalks produced the reported change. Future projects should track activity before and after opening and compare similar neighborhoods with and without new parks.”

Question 8 asks: Which statement best captures the author's main point?

1. [object Object]
2. [object Object]
3. [object Object]
4. [object Object]
5. [object Object]

Answer: C. The author is cautious about causation and proposes a better research design. A and E are absolute recommendations the passage does not make. B attributes the effect to sidewalks even though the author says the study cannot separate causes. D reverses the reported finding.

Question 9 asks: Why does the author mention the new sidewalks?

1. [object Object]
2. [object Object]
3. [object Object]
4. [object Object]
5. [object Object]

Answer: A. The sidewalks are a second intervention that may explain the same outcome, making the park's causal effect difficult to isolate. B and E overstate or contradict the passage. C is not the paragraph's purpose, and D is false: the author calls for a future comparison rather than saying the study already had one.

How to review the set

For each question, record the task and the evidence that decides the answer. In Question 5, the arrow direction exposed the flaw. In Question 7, matching the same reversal mattered more than shared topic words. In the reading passage, the author's cautious wording ruled out choices that made a stronger causal claim than the text supported.

Keep an error log with the question type, your answer, the correct answer, and why the distractor attracted you. A useful entry is “I reversed a necessary condition” or “I treated a study with two interventions as proof of one cause.” Review the rule later using a new question. Repeating the explanation verbatim does not show that you can apply it elsewhere.

Use official practice alongside original questions

These examples teach selected skills, but they are not a substitute for full official tests. LSAC provides free official practice materials through LawHub, including the digital interface, question elimination, passage highlighting, and explanations in its drill sets. Use unfamiliar official forms to assess timing and readiness. Supplemental questions can help target skills, but their difficulty and score estimates may not match LSAC's test.

During timed practice, answer every item because incorrect answers carry no penalty. Afterward, review questions you missed and those you guessed correctly. Work out why the correct answer satisfies the stem and why each wrong option fails. This process improves reasoning and test judgment together.
