Answer:
The primary purpose of a conclusion in an informative essay is to
B. refer back to the thesis.
Explanation:
In essay writing, the conclusion is the final paragraph. Its purpose is to refer back to the thesis, that is, to restate what was initially claimed by the author. A conclusion should never present new information, examples, or evidence, otherwise it would not be a conclusion at all, but merely an extension of the essay's body. It should wrap up by once again reaffirming the main idea or topic in a shorter manner, with fewer words. Therefore, the best option for this question is B. refer back to the thesis.
