It Is because David Grey beard was the first chimpanzee to trust Jane Goodall
What's the question that needs an answer.
Answer:
Add what article, book, or site the quote comes from
Explanation:
The given sentence can be revised by adding what article, book, or site the quote comes from.
A hyphen after the word <em>writes </em>isn't necessary because all necessary quotation marks are already used. The quote is preceded by a comma and framed with quotation marks, which is correct. This is why the first and last options are incorrect.
The second option is incorrect because analysis would require you to write more sentences, and all you need to do is revise the given one. That leaves us with the third option as the correct one.
