Which answer choice does not contain any punctuation errors? A. "Robins, on the other hand," said Mary, "are masons." B. Sure they are, Mac replied. C. He added "that they drill holes in trees." D. "Are woodpeckers carpenters? Henry asked."
It's not B. It doesn't have quotation marks. Not C because the first word in the quotations needs to be capitalized. Not D because the quotation need to surround the statement. So your answer is A :) Hope this helped :)
