Question

According to MLA format, if the sentence uses the author’s name to introduce a quotation, what information must go in the in-text citation?
The last name and page number

The page number only

The last name and book title

The book title and page number

Answer 1

The answer is: the page number only.

MLA (Modern Language Association) is a formatting style that allows academic writers to structure their texts according to certain guidelines that stipulate both the format and the citation style that their texts should follow. It is mostly used in language and literature studies, although recently it is widely used also in all fields of the humanities.

When referencing an author´s work, and when the name of the author is already mentioned in the sentence preceding the reference, one should only include, in parenthesis, the page(s) referenced.

Answer 2

The correct answer is The page number only

Since you've already mentioned who the author is, you don't have to mention him again. The book title would only be added if you're using multiple sources from the same author. If only one, then the page number only.
