Hi,

we can't infer anything about smokers themselves lying. We can infer that some people who say they know healthy heavy smokers are lying.

I went for D, but I guess E would be stronger to make John not unique. Thanks

E seems more reasonable than D, because for John not to be unique amongst his friends only one needs to not be telling the truth (i.e. "Some" is more reasonable than the more extreme "Most"). . .so E.

I don't fully understand the difference b/n some and most. Some could mean half, less than half or more than half most means definitely more than half. Am I right? And if that is the case how would one be able to tell the difference between the two choices? :roll:

Some means 'at least 1'.
Most means 'greatest quantity'.
e.g. He got the most votes.
If there were 3 people, he could have had 40 votes. So it isn't necessarily more than half. Just 'any majority'.
Most of his friends would imply more than 50% since there will be two groups only - his friends who are telling the truth and his friends who are not telling the truth.

We can say that at least 1 of his friends is lying (so that he is not unique). There is no reason to say that more than 50% of his friends are lying.
Though, ambiguous question according to GMAT standards. I wouldn't worry about it.

All of John's friends say they know someone who has smoked 40 cigarettes a day for the past 40 years and yet who is really fit and well. John does not know anyone like that and it is quite certain that he is not unique among his friends in this respect.

If the statements in the passage are true, then which one of the following must also be true?

(A) Smoking often lie about how much they smoke.
(B) People often knowingly exaggerate without intending to lie.
(C) All John's friends know the same lifelong heavy smoker.
(D) Most of John's friends are not telling the truth.
(E) Some of John's friends are not telling the truth.

Hi!

Here we have an inference question - we're looking for a conclusion that MUST be true based on one or more of the statements in the stimulus.

Inference stimuli are not arguments (i.e. they don't contain evidence, a conclusion and rely on assumptions) - they're usually just a loose collection of facts. Accordingly, it's very difficult to predict the answer to an inference question. Instead, we evaluate each choice, asking if it MUST be true.

Paraphrasing the stimulus:

All John's friends make a claim; John can't make the same claim; it's certain that some of his friends can't as well.

To the choices:

A) Assuming the first word should be "smokers" - no info about what smokers say about their own habits - outside the scope, eliminate A.

B) People "often"... as soon as you see the word "often", we know that B is too extreme. We can't extrapolate about what often happens based on a small sample size. In general, beware of extreme answers on inference questions.

C) The stimulus actually tells us that some of John's friends are in the same position as John, i.e. they can't really make the claim. (C), therefore, must be false - eliminate.

D) We know that John isn't unique, but "most" is too extreme - eliminate (D).

E) Perfect! If John isn't unique among his friends in not being able to make the claim, but ALL of his friends have made it, then SOME of them must be lying - choose (E)!

To skovinsky,

My ans is D. Would you explain a little bit why can't it be D?

From my view, What if John is really unique, would the ans is D?
Moreover, the question state quite clear that all of his friends know sbd smoke hard but still healthy.
Since the question is extreme, our answer should extreme too.

+1 E

Cannot be D because the argument mentions "...he is not unique among his friends in this respect". In this sense, probably there is only one of his friends who is providing wrong information. Thefore, you cannot say that MOST of his friends are not telling the truth.

'he is not unique among his friends in this respect.' this statement is the difference between D and E .D can not be inferred from this statement alone , 'most' of john's friends don't have to be different from john to make him 'not unique'.

if only 1 friend is like him , than he is not unique .hence E

In the group there are some more people apart from John who also don't know such a person.
Thus E fits in perfectly.

This question is actually not testing our logical thinking so much as it is testing our comfort level in English.

John does not know anyone like that and it is quite certain that he is not unique among his friends in this respect.

John does not know anyone like that and it is also true that John is not the only one, who doesn't know any such person, among his friends.

That was a toughie. I will go with E though.
S1: ALL of John's friends know someone who smokes 40cigs a day and is fit.
S2: John does not anyone like that AND is CERTAIN that he is not alone among his friends in that aspect.

This implies that there are some friends who are lying. Otherwise John would not be CERTAIN that he is not alone.
