I am going to assume that "after the Dark Ages" is underlined. If so, the correct answer is C. It cannot be any of the "clauses" since it isn't a clause - there is no verb present, so it must be a phrase. It is not an "adjective", since there is no noun which it modifies, but a verb "flourished". Therefore the correct answer has to be C, that is the only available option here.
2. 1st person
3. Conflict
4. Protagonist
That's all I know
Hope this helps
Ralph is a good example of a leader. He is fair to everyone.
I think it’s going to be B
