D would be the answer because an imperative sentence is more of a request
I believe the answer to your question is B) Over 5,000 years ago, ancient Egyptians used wind to sail ships on the Nile River.
this sentence from the passage would be irrelevant because it does not contain usable information on wind turbines as well as the fact that it is a time in history therefore it is irrelevant because you need information that is relatively up-to-date.
The answer would be C, Oedipus going from a hero to finding out he's a murderer, etc.
