Easy LSAT Main Point Questions Practice Questions

Concept Explanation

An LSAT Main Point question requires you to identify the primary conclusion that the author is attempting to prove throughout the stimulus.

On the Law School Admission Council's official LSAT exam, these questions test your ability to distinguish between supporting evidence and the ultimate claim. The main point is not merely a factual statement within the text; it is the specific proposition for which all other sentences in the passage provide support. To find it, look for conclusion indicators such as "therefore," "thus," or "hence," but be careful—the LSAT often places the main point at the beginning or middle of the stimulus to trick readers who only look at the end. A reliable strategy is to ask yourself, "Which sentence is supported by everything else, but doesn't support anything else?" If you can identify the "why" behind the author's writing, you have found the main point.

For those beginning their journey in LSAT Prep, mastering these questions is the foundation for more complex logical reasoning tasks. Unlike GRE main idea questions, which often focus on thematic summaries, LSAT main point questions are strictly about the logical structure of an argument.

Solved Examples

1. Stimulus: Many people believe that eating chocolate causes acne. However, recent dermatological studies have shown no correlation between cocoa consumption and skin breakouts. Therefore, the belief that chocolate causes acne is scientifically unfounded.
   Question: Which one of the following most accurately expresses the main point of the argument?
   Solution:
   1. Identify the conclusion indicator: The word "Therefore" signals the final sentence.
   2. Evaluate the support: The first sentence introduces a common belief. The second sentence provides evidence (studies). The third sentence uses that evidence to make a claim.
   3. Final Answer: The main point is that the belief linking chocolate to acne is scientifically unfounded.
2. Stimulus: The city council should not approve the new stadium proposal. The project is projected to cost $200 million, which would drain the municipal reserve. Additionally, the proposed site is currently a protected green space.
   Question: What is the main conclusion of the argument?
   Solution:
   1. Analyze the structure: The first sentence is a recommendation. The following two sentences provide reasons ($200 million cost and green space protection) to follow that recommendation.
   2. Test the relationship: Does the cost prove the council shouldn't approve it? Yes. Does the fact they shouldn't approve it prove the cost? No.
   3. Final Answer: The city council should reject the new stadium proposal.
3. Stimulus: High-speed rail is often touted as the future of travel. But high-speed rail requires massive infrastructure investment that most mid-sized cities cannot afford. It follows that high-speed rail is an impractical solution for the transportation needs of most mid-sized cities.
   Question: Which one of the following most accurately captures the author's main point?
   Solution:
   1. Identify the shift: The author starts with a common view ("often touted") and then counters it with "But."
   2. Locate the conclusion: The phrase "It follows that" introduces the final claim.
   3. Final Answer: High-speed rail is not a practical transportation solution for most mid-sized cities.

Practice Questions

1. It is a mistake to assume that all organic produce is healthier than conventionally grown produce. Some organic farms use natural pesticides that are actually more toxic to humans in large quantities than synthetic alternatives. Furthermore, conventional produce is often fresher because it is transported shorter distances.

2. The new software update will likely decrease office productivity. While the update adds several new features, the interface is so counterintuitive that employees will spend hours learning to navigate it. Any gain in feature set will be offset by the time lost to training.

3. Some critics argue that the novelist’s latest book is a failure because it lacks a linear plot. However, this criticism ignores the fact that the book is intended to mimic the fragmented nature of human memory. Because the book achieves its goal of representing memory accurately, it should be considered a success.

4. Many homeowners plant mint in their gardens to deter pests. However, mint is an invasive species that quickly spreads and chokes out other plants. Therefore, homeowners should consider using alternative pest-deterrent plants instead of mint.

5. Regular exercise is essential for cardiovascular health. Studies show that individuals who walk at least 30 minutes a day have a 20% lower risk of heart disease. Consequently, doctors should emphasize walking as a primary preventative measure for heart issues.

6. The recent decline in honeybee populations is a threat to global food security. Since bees pollinate one-third of the food we eat, their disappearance would lead to massive crop failures. Governments must prioritize funding for bee conservation research immediately.

7. Using an AI Exam Simulator can significantly reduce test anxiety. By mimicking the actual pressure of a timed environment, students become desensitized to the stress of the exam. Therefore, students who struggle with nerves should incorporate simulated tests into their routine.

8. The belief that cold weather causes the common cold is a myth. The cold is caused by viruses, not temperature. People simply stay indoors more during winter, which increases the likelihood of viral transmission between individuals.

Answers & Explanations

1. Answer: It is a mistake to assume that all organic produce is healthier than conventionally grown produce.
   Explanation: The first sentence is the conclusion. The author provides two reasons (toxic natural pesticides and freshness) to support the idea that organic isn't always healthier.
2. Answer: The new software update will likely decrease office productivity.
   Explanation: The first sentence makes a prediction. The rest of the passage explains why that prediction is likely (counterintuitive interface and training time).
3. Answer: The novelist’s latest book should be considered a success.
   Explanation: The author counters the critics' view. The final sentence, introduced by "should be," represents the author's primary claim based on the book's goal of mimicking memory.
4. Answer: Homeowners should consider using alternative pest-deterrent plants instead of mint.
   Explanation: The word "Therefore" introduces the final recommendation, which is supported by the fact that mint is invasive.
5. Answer: Doctors should emphasize walking as a primary preventative measure for heart issues.
   Explanation: The word "Consequently" marks the conclusion. The previous sentences provide the medical justification for this recommendation.
6. Answer: Governments must prioritize funding for bee conservation research immediately.
   Explanation: The entire argument builds toward a call to action. The threat to food security and the role of pollination serve as premises for the need for government funding.
7. Answer: Students who struggle with nerves should incorporate simulated tests into their routine.
   Explanation: The author provides a reason (desensitization) to support the final recommendation regarding study habits.
8. Answer: The belief that cold weather causes the common cold is a myth.
   Explanation: The author states this claim directly in the first sentence. The following sentences explain what actually causes the cold and why the myth persists.

Frequently Asked Questions

What is the difference between a main point and a sub-conclusion?

A sub-conclusion is a claim that is supported by a premise but also serves as support for the final main point. The main point is the ultimate conclusion that does not support any further claims within that specific argument.

Do I need to look for conclusion indicators every time?

While indicators like "therefore" and "hence" are helpful, you should primarily focus on the logical relationship between sentences. Some of the most difficult questions omit these keywords entirely to test your reading comprehension.

Can the main point be a question?

No, the main point must be a statement or a claim. If the author asks a rhetorical question, the main point is usually the answer that the author implies or provides through their evidence.

Should I bring in outside information to help identify the main point?

Absolutely not. You must identify the main point based strictly on the logic provided in the stimulus, even if you disagree with the author's facts or reasoning in the real world.

How do I handle passages with two opposing viewpoints?

In these cases, the main point is usually the author's reaction to the first viewpoint. Look for words like "however" or "but" to find where the author begins to state their own primary conclusion.
