请问FEIFEI LOGIC-99，详解版也没看懂，ft!

99. Concetta: Franchot was a great writer because she was ahead of her time in understanding that industrialization was taking an unconscionable toll on the family structure of the working class.

Alicia: Franchot was not a great writer. The mark of a great writer is the ability to move people with the power of the written word, not the ability to be among the first to grasp a social issue. Besides, the social consequences of industrialization were widely understood in Franchot’s day.

In her disagreement with Concetta, Alicia does which one of the following?

(A) accepts Concetta’s criterion and then adds evidence to Concetta’s case

(B) discredits Concetta’s evidence and then generalizes from new evidence

(C) rejects Concetta’s criterion and then disputes a specific claim

(D) disputes Concetta’s conclusion and then presents facts in support of an alternative creterion

(E) attacks one of Concetta’s claims and then criticizes the structure of her argument

答案选C,请哪位大侠帮我解释一下为什么不能选D好吗？

十分感谢！
