Study the given information carefully and answer the question that follows.

Eight members—P, Q, R, S, T, U, V, and W—belong to a three-generation family with no single parent. P is married to Q and is the grandfather of W. T is the daughter-in-law of Q. R has only one child, V, who is female. S is the sister of R and is married to U. W is the son of U.

How many male members belong to this family?

The correct answer is Four.

Step-by-step breakdown:

1. Identify Generation 1 (Grandparents):
- The family consists of eight members across three generations with no single parent.
- P is married to Q and is the grandfather of W.
- Therefore, P is male (Grandfather) and Q is female (Grandmother).

2. Determine Generation 2 (Parents):
- S is the sister of R and is married to U. Thus, S is female and U is male.
- Since S and R are siblings, they are children of P and Q.
- T is the daughter-in-law of Q, meaning T is female and married to Q's son, R. Therefore, R is male.

3. Determine Generation 3 (Children):
- W is the son of U (and S), so W is male.
- V is the only child of R (and T), and is given as female.

4. Count the male members:
- Male members (4): P, R, U, and W.
- Female members (4): Q, S, T, and V.

Hence, there are 4 male members in the family.
