Hard LSAT Most Strongly Supported Questions With Answers Practice Questions

Most Strongly Supported questions on the LSAT require identifying the claim that is best proven by the provided stimulus, even if it is not logically guaranteed. These questions appear frequently in the Logical Reasoning section and test your ability to draw reasonable inferences from a set of facts or premises. Unlike Must Be True questions, which demand 100% logical certainty, Most Strongly Supported questions allow for a small degree of inductive reasoning, though the correct answer remains the one that stays closest to the text.

Success on these high-difficulty items depends on your ability to avoid common traps, such as choices that are too broad, introduce new information, or confuse a correlation with a definite cause. You should focus on combining two or more premises to see what they collectively imply. If you find yourself struggling with the logic of these patterns, exploring LSAT Prep resources can help you build the foundational skills necessary for more complex deductions. Often, the correct answer is a "weak" claim—using words like "some," "many," or "may"—because these are easier to support than bold, sweeping generalizations.

Concept Explanation

Most Strongly Supported questions ask you to select the statement that is most likely to be true based on the provided evidence. These questions differ from Must Be True questions because the threshold for proof is slightly lower; however, the LSAT still rewards conservative inferences over speculative ones. When approaching these, treat the stimulus as a set of facts and do not bring in outside knowledge. The answer must be a direct consequence of the information given.

To identify these questions, look for phrasing such as "Which one of the following is most strongly supported by the information above?" or "The statements above, if true, provide the most support for which one of the following?" According to the Law School Admission Council, the Logical Reasoning section evaluates your ability to analyze and evaluate arguments. In the context of support questions, this means looking for the "overlap" between premises. For instance, if you know that all mammals have hearts and most mammals live on land, you can strongly support the idea that some land-dwelling creatures have hearts.

Key strategies for these questions include:

• Avoid the "New Information" Trap: If an answer choice mentions a concept not discussed in the stimulus, it is almost certainly wrong.
• Check the Logical Strength: Weakly worded answers (e.g., "not all," "at least some") are easier to support than strong ones (e.g., "always," "never").
• Combine Premises: Look for a common term that links two different sentences together.
• Beware of Converse/Inverse Fallacies: Just because $A \rightarrow B$, it does not mean $B \rightarrow A$.

Solved Examples

1. Example: Every student who attended the seminar received a certificate. Most of those who received a certificate were also given a free textbook. No student who received a free textbook failed the final exam.
   Solution:
   1. Identify the links: Seminar $\rightarrow$ Certificate; Certificate (most) $\rightarrow$ Textbook; Textbook $\rightarrow$ Passed Exam.
   2. Combine: Since most certificate holders got a textbook, and all textbook holders passed, at least some people who got certificates passed the exam.
   3. Inference: At least some students who attended the seminar passed the final exam. This is strongly supported because the seminar attendees are a subset of the certificate holders.
2. Example: In the last decade, the population of wolves in the northern woods has doubled. During the same period, the population of deer, the wolves' primary prey, has decreased by 30%. Local hunters claim that the wolves are the sole cause of the deer population decline.
   Solution:
   1. Note the facts: Wolves up, Deer down.
   2. Note the hunter's claim: Wolves are the sole cause.
   3. Evaluate support: While the facts suggest a correlation, they do not prove the wolves are the sole cause. However, it is strongly supported that the increase in a predator population occurring simultaneously with a decrease in prey population is consistent with the hunters' hypothesis.
   4. Correct Inference: The data regarding wolf and deer populations is consistent with the claim that wolves have had a negative impact on the deer population.
3. Example: If a company invests in new software, it must train its employees. Company X invested in new software last year, but its overall productivity did not increase.
   Solution:
   1. Identify the conditional: Software $\rightarrow$ Training.
   2. Apply to Company X: Company X got software, so Company X must have trained its employees.
   3. Analyze the result: Training happened, but productivity stayed flat.
   4. Inference: Employee training does not always result in an increase in overall productivity. This is strongly supported because we have a specific counterexample (Company X).

Practice Questions

1. Archaeologists have found evidence that ancient civilization A traded extensively with civilization B. Civilization B is known to have possessed advanced metallurgical skills, while civilization A did not. However, tools made of a specific copper alloy unique to civilization B's region have been found in the ruins of civilization A.
2. Most successful novelists write every day. Some people who write every day never publish a book. However, anyone who publishes a bestseller must have a literary agent.
3. The city's new traffic light system was designed to reduce congestion. Since its implementation, average commute times have increased by 15%. During this same time, the number of registered vehicles in the city grew by 20%.

4. All research assistants in the chemistry lab are required to wear safety goggles. No one wearing safety goggles is permitted to wear contact lenses. Sarah is a research assistant in the chemistry lab.
5. Recent studies show that individuals who consume more than three cups of coffee a day have a 20% lower risk of developing certain heart conditions than those who consume no coffee. However, coffee drinkers also tend to exercise more frequently than non-coffee drinkers.
6. If the government raises taxes, consumer spending will decrease. If consumer spending decreases, the economy will enter a recession. The economy is currently growing at a healthy rate.
7. Every member of the board of directors voted in favor of the merger. Some of the board members are also major shareholders in the company. No major shareholder wants the company's stock price to drop.
8. A rare species of orchid only grows in soil with a pH level between $5.5$ and $6.0$. The soil in the northern valley has a pH of $6.5$. A botanist recently discovered a cluster of these rare orchids in the southern valley.
9. To win the championship, a team must have both a strong defense and a high-scoring offense. The Tigers have the highest-scoring offense in the league, but they lost the championship game.
10. Most people who own electric cars also have solar panels installed on their homes. Very few people who have solar panels installed on their homes live in apartments.

Answers & Explanations

1. Answer: Some tools found in civilization A were likely produced by civilization B or made using materials from civilization B.
   Explanation: The stimulus notes that civilization A lacked metallurgical skills and that the alloy found there is unique to civilization B's region. Given the trade history, it is strongly supported that these tools originated from B.
2. Answer: Writing every day does not guarantee that one will publish a bestseller.
   Explanation: The text states some people who write every day never even publish a book. Therefore, it follows that writing every day is not a sufficient condition for the much higher bar of publishing a bestseller.
3. Answer: The increase in commute times cannot be attributed solely to the new traffic light system.
   Explanation: While commute times rose after the light system was installed, the 20% increase in vehicles is a significant confounding variable that likely contributed to the congestion.
4. Answer: Sarah is not permitted to wear contact lenses while in the chemistry lab.
   Explanation: This is a transitive deduction: Sarah $\rightarrow$ Assistant $\rightarrow$ Goggles $\rightarrow$ No Contacts.
5. Answer: The lower risk of heart conditions in coffee drinkers might be partially due to their exercise habits rather than the coffee itself.
   Explanation: Because coffee consumption is correlated with exercise, and exercise affects heart health, we cannot conclude coffee is the sole cause of the benefit.
6. Answer: The government has not raised taxes.
   Explanation: This uses the contrapositive. If Taxes $\rightarrow$ Recession, then No Recession $\rightarrow$ No Taxes. Since the economy is growing (No Recession), taxes weren't raised.
7. Answer: At least some people who voted for the merger do not want the company's stock price to drop.
   Explanation: Some board members (voters) are major shareholders, and no major shareholders want the price to drop. Therefore, those specific board members do not want the price to drop.
8. Answer: The soil in the southern valley likely has a pH level between $5.5$ and $6.0$.
   Explanation: Since the orchid only grows in that specific pH range, finding the orchids there strongly suggests the soil meets that requirement.
9. Answer: The Tigers did not have a strong defense.
   Explanation: To win, you need Defense AND Offense. The Tigers had the Offense but still lost. Therefore, they must have lacked the other necessary condition: a strong defense.
10. Answer: Most electric car owners do not live in apartments.
    Explanation: Most electric car owners have solar panels, and very few people with solar panels live in apartments. This suggests a significant overlap between electric car owners and non-apartment dwellers.

Frequently Asked Questions

What is the difference between Must Be True and Most Strongly Supported?

Must Be True questions require the answer to be a logical certainty that is 100% proven by the stimulus. Most Strongly Supported questions have a slightly lower threshold, where the correct answer is the most plausible inference even if other unlikely possibilities exist.

Can I use outside information for these questions?

No, you must rely exclusively on the information provided in the stimulus. Bringing in outside facts, even if they are true in the real world, will often lead you to choose a trap answer that is not supported by the specific text provided.

How do I handle "Most" and "Some" in these questions?

Treat "most" as meaning "more than half" (51-100%) and "some" as meaning "at least one" (1-100%). Many hard questions rely on the fact that you cannot necessarily conclude a "most" relationship from two "some" relationships.

Should I look for the conclusion in the stimulus?

Often, Most Strongly Supported stimuli are just sets of facts without a formal conclusion. Your job is to act as the author and determine what conclusion those facts best support, rather than identifying a conclusion already present.

How can I improve my speed on these questions?

Practice identifying the "logical force" of words (e.g., all, most, many, some, none). Using tools like the AI Question Generator can provide the volume of practice needed to recognize these patterns instantly without over-analyzing every choice.
