求助 LSAT-1-1-2

Handwriting analysis—also known as graphology—is a poor way to predict personality types, even though it is used by 3,000 United States firms and by a majority of European companies. In a recent study, five graphologists scored no better than chance in predicting the occupations of forty professionals.

Which one of the following is an assumption necessary to the argument?

(A) People in the same occupation usually do not have the same personality type.

(B) Graphology is an effective means of predicting personality types in non-business contexts.

(C) There are more United States firms that do not use graphology than all the United States and European firms that do use it.

(D) There are several other techniques for predicting personality types that are more accurate than graphology.（E）

(E) There is a correspondence between type of personality and choice of occupation.

文章中说“graphology—is a poor way to predict personality types”，后面再提到另外一个现象，但为什么要用一个假设E来联系他们呢？因为感觉文章前面是把graphology否了，但为什么答案又重提它？请教NN们
