Show the answer and the worked solution
Correct answer: B. Great-grandson
Worked solution
- A → B is one generation, B → C is two, C → E is three.
- Three generations below A makes E his great-grandson.
Answer: Great-grandson.
The idea
Count the parent-child links: one is a child, two a grandchild, three a great-grandchild.
Shortcut. E is a son, so the answer is male; three downward links from A (A → B → C → E) make him a great-grandson, not a grandson.
Common trap. "Grandson" — counting the people between A and E (B and C) instead of the three links, which drops one generation.
