Directions: Read the following information carefully and answer the questions that follow.

Eight members belong to a family that contains exactly two married couples. H is the grandmother of Y. V is the son-in-law of R. B has exactly two children, who are of opposite genders. P is the only brother of Q, and Q is female. W is the brother-in-law of V. W is the uncle of Q. Y is the niece of Q. Q and B are of the same gender.

How is R related to Q?

Correct Answer: Grandfather

Step-by-Step Explanation:

To determine the relation between R and Q, let us break down the clues step-by-step and reconstruct the family tree consisting of 8 members and 2 married couples.

1. Identify Siblings and Gender of Q and B:
• P is the only brother of Q, and Q is female. Therefore, P is Male (+) and Q is Female (-).
• Q and B are of the same gender. Since Q is female, B is Female (-).
• B has exactly two children of opposite genders. Since P is male and Q is female, P and Q are the two children of B.
• W is the uncle of Q. Since B is the mother of Q, W is Male (+) and is the brother of B.

2. Determine Married Couples and In-Law Relations:
• V is the son-in-law of R. Since B is female, she must be married to V. Thus, V is Male (+), and (V, B) forms the first married couple.
• Since V is the son-in-law of R, R must be the parent of B (and W).
• W is the brother-in-law of V (wife's brother), which aligns with W being B's brother.

3. Determine Grandparent Generation:
• H is the grandmother of Y. Since there are exactly 2 married couples in the family, the top (1st) generation consists of R and H as the married couple.
• Since H is a grandmother (female), H is Female (-) and R is Male (+).
• Y is the niece of Q. Since P is Q's only brother, Y is the child of P, making H and R the grandparents of the 3rd generation (P, Q, and Y).

4. Generation Hierarchy Summary:
• 1st Generation (Grandparents): R (Male, Grandfather) married to H (Female, Grandmother)
• 2nd Generation (Parents & Uncle): V (Male) married to B (Female); W (Male, Brother of B)
• 3rd Generation (Children): P (Male, Son of B & V), Q (Female, Daughter of B & V), Y (Child of P)

Conclusion:
Since R is the father of B, and B is the mother of Q, R is the Grandfather of Q.
