The Rorschach test — also known as the inkblot test

The Rorschach test —also known as the inkblot test—is a poor way to predict personality types, even though it is used by many leading United States firms and by a majority of European companies. In a recent experiment five psychiatrists administered the Rorschach test to forty professionals. Interestingly, these psychiatrists scored no better than chance in predicting the occupations of the 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) The Rorschach test is an effective means of predicting personality types in non-business contexts.
(C) There are more United States firms that do not use the inkblot test 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 the Rorschach test.
(E) There is a correspondence between type of personality and choice of occupation.
