In The Sherlock Society, which 'W' is responsible for investigating the people in the Al Capone mystery?

• A. Who
• B. What
• C. Where
• D. Why

Answer: (A)

The question is testing which question word is used when you’re focusing on people and their identities. When you want to uncover who is involved, who did something, who witnessed something, or who was affected, you use the interrogative that targets people—“Who.” That’s why it’s the best fit for investigating the people in the Al Capone mystery.

Think of the other “W” words as addressing different angles: What asks about events or things, Where pinpoints location, and Why asks for motives. Each serves a different purpose, but to identify the people and roles in a mystery, “Who” is the one that directly targets persons.
