Essayist: Wisdom and intelligence are desirable qualities. However,

(A) Most people are neither intelligent nor wise( incorrect)
(B) Most people are both intelligent and wise(contradicting, and incorrect)
(C) No one is both wise and intelligent(eliminate easily)
(D) No one is either wise or intelligent(correct)
(E) Many people are intelligent and yet lack wisdom(eliminate as it is way too general)

From Manhattan Forum-

I --/-> W

W --/-> I

Note: --/-> = Is not required

The other sentence states essentially that one person has documented some people being I or W, not both.

So let's see what must be false:

A) Most people neither I or W. This can be true. We need to think that the only information we have is what one person has witnessed among some people.

B) Same issue as A.

C) Too strong. We know that from one person's witness accounts that this is something not occurring. But does this hold for other people that he has possibly not encountered? That possibility makes this a could be true situation.

D) No one is either W or I. Must be false. We know that there is a case of someone being at least one or the other. Look at the last sentence of the stimulus. We have that situation occurring.

E) Perfectly consistent with the essayist's statements. Definitely not something that must be false.
