Why does Virginia Jackson say she suspected people came knocking on her door asking about her grandfather?

• A. They were looking for the treasure
• B. They wanted directions
• C. They sought a loan
• D. They wanted an autograph

Answer: (A)

The main idea being tested is how to infer a character’s motive from what they do and what that implies about the situation. Virginia’s remark—people knocking on her door asking about her grandfather—suggests there’s something about him that others want to know or obtain. In this context, the most fitting motivation is that they’re searching for information about a treasure linked to the grandfather. The other motives don’t fit the setup: asking for directions wouldn’t center on the grandfather, a loan would focus on money rather than family connections, and an autograph would imply fame or a living celebrity, not interest tied specifically to the grandfather and any treasure he’s associated with. So the reason they came knocking is best understood as they were looking for the treasure.
