Question

the thesis of a research paper is an example of what?
a. a signpost
b. the bottom line (your key message)
c. a preview
d. a headline

Explanation:

The thesis of a research paper is the central claim or the key message that the author wants to convey. A signpost is a statement that indicates the direction of the paper but is not the core message. A preview gives an overview of what's to come, and a headline is a title - like statement. The bottom - line or key message is what the thesis represents.

Answer:

B. The bottom line (your key message)
