Answer 1

1. You need to choose one of those 7 states or provinces.

2. Think of three yes-or-no questions that someone could ask you that would help them figure out which state or province you'd chosen. The first question could be "Are there 7 letters in the name?" (If yes, then it would narrow it down to two choices.)
