Question

P's brother is Q. Q is the father of R. R is the sister of S. How is S related to P?

• A. Son
• B. Nephew
• C. Niece
• D. Cannot be determined

Answer 1

Answer:

D. Cannot be determined

From the information:

• P's brother is Q.

• Q is the father of R.

• R is the sister of S.

We can conclude that S is also Q's child, so S is P's brother's child.

However, S's gender is not given:

• If S is male, S is P's nephew.

• If S is female, S is P's niece.

Since the exact relationship depends on S's gender, it cannot be determined uniquely.

Answer: Cannot be determined.
