What factor led Alex to think he should start a detective agency?

• A. His last name is Sherlock
• B. He solved a mystery before
• C. He wanted to prove himself
• D. He found a hidden note

Answer: (A)

The main idea here is how a person’s name or identity can shape big life decisions. Having a last name that echoes a legendary detective makes the detective path feel plausible and exciting for Alex. It’s as if the name carries a built-in cue that he could adopt that role, and starting a detective agency becomes a natural way to live up to or play with that legacy. The other factors—solving a mystery before, wanting to prove himself, or finding a hidden note—don’t tie his motivation to the sense of identity sparked by his name. The name creates a brand and a sense of possibility that nudges him toward opening a detective agency.
