Answer 2

"Agreement Statement

       The sentence “They were not self-sufficient?” is an agreement statement because, in this sentence, the speaker asks the other person a statement which the speaker agrees on. Even though the statement looks like a disagreement statement, the question mark in the last expresses doubtfulness, it also gives us the hint of the speaker already being clear about his stance.

       Changing the sentence to “Weren't they self-sufficient?” will impart more meaning of the sentence being an agreement."
