16. Essayist: Wisdom and intelligence are desirable qualities. However, being intelligent does not imply that one is wise, nor does being wise imply that one is intelligent. In my own experience, the people I meet have one or the other of these qualities but not both.
If the essayist's statements are true, then each of the following could be true EXCEPT:
(A) Most people are neither intelligent, nor wise.
(B) Most people are both intelligent and wise.
(C) No one is both wise and intelligent.
(D) No one is either wise or intelligent.
(E) Many people are intelligent and yet lack wisdom.
答案为D, 请问应如何推导, B为什么不对,谢谢

You are misled by the statement. The answer for "could be true except" cannot be true, or must be false based on the statement.

D is definitely untrue as it is contradictary to "...the people I meet have one or the other of these qualities...".

You cannot rule out the possiblility of B soly based on the statement. If you choose B, you made an assumption that the Essayist has met MOST people on earth. Let us assume that the Essayist just met one person in his or her life and this person is the only one on earth who only possess one quality, while the rest of human being possee both. It is a ridiculously extreme assumption but that is how you crack questions like this. The statement simply did not rule out this possibility.

Also pay attention to words implying degree, such as most, which indicate more than 50%. You need to make sure that more than 50% is clearly stated in the passage.

I remember that mindfree once said that 'possible' indicates more than 80%,can you tell us other possibility degrees?

such as :most >50%
may<=50%

tks

Possible is not 80%. Probable is. Possible means may or may not. I am not very sure about how much it is.

Most refers to at least over 50%.
