Directions: Read the following relationship details and answer the question.

X's mother's husband's mother has a son named Y, who is the only brother of X's mother. If X is a female member of the family, how is X related to Y?

Correct Answer: Niece

To determine how X is related to Y, let us break down the given family relationships step-by-step:

1. "X's mother's husband": Assuming standard blood relations, a mother's husband is X's father.

2. "X's mother's husband's mother": This refers to X's father's mother (i.e., X's paternal grandmother).

3. "X's mother's husband's mother has a son named Y": Y is a son of X's paternal grandmother. Thus, Y is either X's father or X's paternal uncle.

4. "who is the only brother of X's mother": This crucial clue tells us that Y is the brother of X's mother (X's maternal uncle).

5. Since X is a female member of the family, X is the daughter of X's mother.

6. Therefore, X is the sister's daughter (niece) of Y.

Hence, X is the Niece of Y.
