Paragraph four of Anna Quindlen "Quilt of a country" is mainly constructed with questions, and repeats the words "What is the point" at the beginning of each question.
She is trying to prove her point, that despite all of the cultures and ethnicities and different backgrounds that constitute the American people, it is not enough to disintegrate the nation, while other countries were torn apart by these differences.
I think the most grammatically correct answer is actually B. Correct me if I am wrong.
That the residents of Salem were scared that witches would somehow use their power against innocents. And that anyone that seemed sketchy was a witch/warlock out to get people for their pleasure
