Anticipation
It's difficult to anticipate anything specific, so let's just go to the answers and look for something that must be false.
16.
If the essayist's statements are █████ ████ ████ ██ ███ █████████ █████ ██ ████ ███████
a
Most people are ███████ ███████████ ███ █████
Could be true. The stimulus commits us to at least one intelligent person and at least one wise person existing. But most of the population could be neither. Since (A) could be true, it's wrong on this EXCEPT question.
b
Most people are ████ ███████████ ███ █████
Could be true. The phrase in my own experience in the last sentence limits it to people the essayist has personally met. Globally, most people could be both intelligent and wise. The essayist just hasn't met those people. Although we know from the second sentence that some people can have one quality without the other, it's still possible that most people have both qualities. Since (B) could be true, it's wrong on this EXCEPT question.
c
No one is ████ ████ ███ ████████████
Could be true. The stimulus tells us some people are intelligent-but-not-wise and some are wise-but-not-intelligent, but it never commits to the idea that there must be some people who are both wise and intelligent. The "both" group could be empty. Since (C) could be true, it's wrong on this EXCEPT question.
d
No one is ██████ ████ ██ ████████████
Must be false. The author said she knows people who have one of the qualities of wisdom or intelligence, but not both. That means there’s at least one person out there who has wisdom or intelligence. (D), however, asserts that no one has either quality. In other words, that there's nobody wise and nobody intelligent. That contradicts the fact that the author knows people who have at least one of those qualities.
e
Many people are ███████████ ███ ███ ████ ███████
Could be true. We know that some intelligent-but-not-wise people exist. But the stimulus doesn't put a cap on how many. So it's possible that there are many intelligent-but-not-wise people. Since (E) could be true, it's wrong on this EXCEPT question.
