Question

In 1965, King helped plan a march to protest the lack of voting rights for African Americans in Alabama. However, the first attempt at the march ended after just six blocks when police attacked the marchers.1 King deliberately cut short the second attempt to avoid additional violence. Finally, after securing greater official protection, King was able to successfully lead the march on the third attempt.

1. See Garrow 395–98 for a timeline of events leading up to the police attack on the marchers.

2. King knew in advance that he would cut the second attempt short. See Garrow 403–04.
What is the correct in-text formatting for the second footnote reference in this passage?

King deliberately cut short the second attempt to avoid additional violence (2).
King deliberately cut short the second attempt to avoid additional violence2.
King deliberately cut short the second attempt to avoid additional violence.2
King deliberately cut short the second attempt to avoid additional violence.2

Answer 1

Place the footnote number after the sentence punctuation as a superscript. For example:

King deliberately cut short the second attempt to avoid additional violence.^2

(So the third option is correct, but the "2" should be superscript.)
