The original quotation in the fictional text by Atchison, Topeka, and Santa Fe (2009) is as follows: "Because of overemphasis on academic excellence, especially test grades, the high schools studied had a disproportionate number of students who reported sleeplessness, nervousness, nightmares, and guilt. These were attributed to various factors, the most significant of which was a very strict principal, who voiced open disapproval of students she felt were underachieving their enormous academic potential. Parents were very accepting of this behavior, echoing it in their interactions with the students." What is the acceptable way to properly attribute this content in a literature review?
