Question

Which option best revises this sentence to use the correct in-text citation, according to MLA standards?

Answer 1

The answer for your question is A. 

Answer 2

The correct answer is A. Transportation planner Sarah Reidel defines abbreviated work schedules as those that are "regularly less than 40 hours per week" (47).

Explanation:

In-text citations are the use of words and ideas  from someone else during the text to explain, support or clarify your own ideas, this can happen in two main ways by using the exact words of the other author which is called a quotation or by paraphrasing which about using your words to refer to someone else ideas. In any of these cases, it is necessary you let the reader know to whom these ideas or words belong, because of this the MLA Manual which is a guide for writing and publishing documents, establishes in the case of quotes the last name of the author should be mentioned and the number of the page where that words appear in the original document, this can be done by first mentioning the author's name during the text and writing the number page in parentheses after the quotation or by writing both the last name of the author and page number in parentheses but omitting mentioning the author during the text.

Considering this in the case of the citation presented in the question it is necessary to avoid writing Sarah Reidel twice whether by omitting it at the beginning or at the end of the sentence. Thus, the correct answer is option A as this follows the rules established by the MLA of mentioning the author at the beginning then adding the quote and finally the page number in parentheses without mentioning the author again.
