Determine Whether the Following Passage Contains an Argument; If It

Essay

Determine whether the following passage contains an argument; if it does, identify the main issue.
"A witty experiment by Philip Goldberg proves what everyone knows, having internalized the disesteem in which they are held, women despise both themselves and each other. This simple test consisted of asking women undergraduates to respond to the scholarship in an essay signed alternately by one John McKay and one Joan McKay. In making their assessments, the students generally agreed that John was a remarkable thinker, Joan an unimpressive mind. Yet the articles were identical; the reaction was dependent on the sex of the supposed author."
-Kate Millett, Sexual Politics
