Wendy has an assignment for her English class to write a research paper on Edgar Allan Poe. What question can Wendy pose to make that topic more manageable?

Assuming this question has no answers but a written one, I'll go with this; Just restate what her subject is (or the question about the subject).

for instance, if she has to write about E. A. P then she could ask questions such as; "Who is Edgar, how old was Edgar when he died, what was Edgar Allen Poe famous for"
