@chelseaborg,

(C) is about disputing the accuracy of one of the explicit premises, whereas (E) is about rejecting one of the implicit assumptions. The argument presumes that because half of the returned items were inspected by Haynes, it must be due to the quality of his work. Young never disputes the fact that half of the returned appliances were inspected by Hayes, but questions if we can assume that the number of returns is truly due to his skill or because he inspects more than others.

Does this make sense?

Let me know if you have any further questions.
