Answer:
The last one, ' interest the reader in the topic and present thesis'
Explanation:
Use POE: process of elimination
You start w an intro. SO logically you won't just randomly put evidence about something when the reader doesn't even know what ur talking about. SO eliminate the first one. It could be the second but most intros don't have questions in them. SO keep a question mark next to that, don't eliminate it. You introduce the topic before you introduce anyone. Introducing the author is more of a side thing. So eliminate. The last one also makes sense so question mark.
Now go back and see what options are left. See the one that makes most sense.
That's the last option, ' interest the reader in the topic and present thesis'
