Show the answer and the worked solution
Correct answer: B. Wife
Worked solution
- A is B's brother and A and D are brothers, so A, B and D are siblings.
- E is B's mother, so E is the mother of all three, including D.
- C is D's father, so C and E are D's parents.
- E is C's wife.
Answer: Wife.
The idea
Collect the siblings first, then identify the shared parents. Two people who are both parents of the same child are spouses.
Shortcut. A, B and D form one set of siblings, so B's mother and D's father are that family's two parents — and the mother and father of the same children are wife and husband.
Common trap. "Mother" — attaching the word 'mother' from 'E is B's mother' to C, when C, as D's father, stands in E's own generation.
