- Since, John is not unique, some of the friends must not know the smoker, so some of them are lying.

(A) Smoking often lie about how much they smoke.
- No relation.

(B) People often knowingly exaggerate without intending to lie.
- No relation.

(C) All John's friends know the same lifelong heavy smoker.
-'Lifelong heavy smoker' is never mentioned in passage.

(D) Most of John's friends are not telling the truth.
- We can not conclude on 'most' part.

(E) Some of John's friends are not telling the truth.
-My take. This one is the answer.

Here I think Lifelong Smoker represent the same guy who is smoking for 40 years.
But option is still incorrect because if all his friend know the gu then he will become unique among the friends which is not true. So this is incorrect.

(D) Most of John's friends are not telling the truth.
- We can not conclude on 'most' part.
Agree that most is close to all. Some is better as mentioned in E.
This is because for John not to be unique ==> we need only some friends who knows (..) not most of them.

(E) Some of John's friends are not telling the truth.
-My take. This one is the answer.

E because "he is not unique" means some of his friends do not know that fact, but the stem says "all of his friends know". So some of his friends must lie...

This post was
BOOKMARKED
Has to be E Since
Arg 1) "All of John's friends say they know someone ..."
Arg 2) "John does not know anyone like that and it is quite certain that he is not unique among his friends in this respect."

Since "all" of John;s friend say they know someone and John believe he doesn't know and he is not "unique" then definetely some of his friends are lying.
