Logical Reasoning Questions for CLAT | QB Set 102

A public policy institute conducted a study on different categories of legal professionals and law students participating in research projects. The report stated that all constitutional law researchers are legal researchers. It also mentioned that all legal researchers are trained in legal writing. 

However, no legal researchers are courtroom clerks, as their roles are entirely different. The report further observed that some law students are legal researchers, while some law students are interns. It clarified that some interns are not legal researchers, as they may be working only on administrative tasks. Additionally, all moot court participants are law students, and some moot court participants are legal researchers because they assist faculty members in academic projects. 

The report did not make any statement about whether all interns are law students or whether courtroom clerks can be interns. It emphasised that conclusions should be drawn only from the given information and not from assumptions. The institute warned that in logical reasoning, every conclusion must strictly follow from the premises without introducing outside facts.

Answers with Detailed Explanations

Answer 1: C

Explanation:

We know:

• All Constitutional Law Researchers → Legal Researchers
• All Legal Researchers → Trained in Legal Writing

Therefore:

All Constitutional Law Researchers → Trained in Legal Writing.

This is a valid chain syllogism.

• A: Cannot be concluded because only some interns are not legal researchers; nothing says any intern is a legal researcher.
• B: Incorrect. Since no legal researcher is a courtroom clerk, it does not mean courtroom clerks cannot be trained in legal writing through some other route.
• D: No such relationship is given.

Correct Answer: C

Answer 2: B

Explanation:

Given:

• Some Moot Court Participants → Legal Researchers
• All Legal Researchers → Trained in Legal Writing

Therefore:

Some Moot Court Participants → Trained in Legal Writing.

• A: Not given.
• C: The passage never says no interns are law students.
• D: No such information is provided.

Correct Answer: B

Answer 3: D

Explanation:

Let’s examine each option.

• A: Some law students are legal researchers, and all legal researchers are trained in legal writing. Hence, some law students are trained in legal writing. This follows.
• B: Constitutional law researchers are legal researchers, and no legal researcher is a courtroom clerk. Hence, no constitutional law researcher is a courtroom clerk. This follows.
• C: All moot court participants are law students. Therefore, any moot court participant is a law student. This follows.
• D: The passage only says some interns are not legal researchers. It never establishes that any intern is a legal researcher. Therefore, it cannot be inferred that some interns are trained in legal writing.

Correct Answer: D

Answer 4: D

Explanation:

We know:

• No Legal Researchers are Courtroom Clerks.
• All Legal Researchers are Trained in Legal Writing.

However, nothing states that all courtroom clerks are trained in legal writing. In fact, since courtroom clerks cannot be legal researchers, this statement has no support and contradicts the distinction made in the passage.

The other options are explicitly stated in the passage.

Correct Answer: D

Answer 5: B

Explanation:

The passage states:

• Some Law Students → Legal Researchers
• All Legal Researchers → Trained in Legal Writing

Hence:

Some Law Students → Trained in Legal Writing.

• A: Not given.
• C: This reverses the given statement. We know all legal researchers are trained writers, not vice versa.
• D: No such conclusion can be drawn.

Correct Answer: B
