What does the argument tell us?

1. Except for Marx, All German philosophers are idealists
2. Marx is not an idealist, but he is German.

Now we need information that allows us to make that argument:

A. Incorrect. All Germans may be idealists, but that does not mean all idealists are German.

B. Incorrect. Marx is German

C. Incorrect. Just because you are German does not make you an idealist. You must be a German phiosopher

D. Incorrect. While this information is correct does it confirm the initial argument? No. This is telling us that Marx is not an idealist German philosopher but it tells us nothing of the other German philosophers. So only half the statement could be made from this information.

E. Correct. This hits all the points. It states all German philosophers are idealist and that Marx is the one exception to the rule.

All German philosophers, except for Marx, are idealists.

From which of the following can the statement above be most properly inferred?

A) Except for Marx, if someone is an idealist philosopher, then he or she is German. <-- Incorrect, German is the precedent of the idealist philosopher(s) not the opposite;

B) Marx is the only non-German philosopher who is an idealist. <-- Incorrect, this doesn't stem from the premise given

C) If a German is an idealist, then he or she is a philosopher, as long as he or she is not Marx. <-- Incorrect, Generalization based on the premise

D) Marx is not an idealist German philosopher. <-- Incorrect, Marx is German philosopher yet

E) Aside from the philosopher Marx, if someone is a German philosopher, then he or she is an idealist. <-- Correct, all words in this answer choice are the restatements of the premise given

German philosophers (if someone is a German philosopher), except for Marx (Aside from the philosopher Marx) , are idealists (then he or she is an idealist).

note however, if the condition would have been put in the past tense, then this answer had signaled us about unreal situation. Good that we have regular condition being set for E).

concur with the reasoning above! it is infact E . Rest are traps ..

I have doubt in above.
D says that "Marx is not an idealist German philosopher"
It doesn't say that "Max is not a German philosopher"

@prachi !

Like its mentioned above. D just says that Marx is not an IDEALIST GERMAN PHILO. Does it say that rest of them are ? or are not ? Does it exclusively say it for Marx or Marx is one of the german philos who are not idealists??? So u cant isolate Marx there from other German philos who were not idealists thats y we dont consider that option quite a strong one..Rather its a trap. It lures u in with the obvious inference part.

Are u getting my point here??

Prachich1987 -

I think that the key point here is what type of question is this?

If you look at the question stem you see that it says "from which one of the following can the statement above be most properly inferred?"

That means that the statement above is the conclusion and you are looking to pick the premise that guarantees the conclusion. Here is something unusual and not a typical GMAT type!

If you read this question stem and treat it as an inference question where the answer choice must be true then D would be true. If the above is the evidence, then we can say that Marx is not an idealist. So it would be true that he is not a German idealist philosopher.

However, we are looking for the answer choice that proves the above conclusion. E does this because it gives you parts - Marx is not idealist and all other German philosophers are.

This is what Fitzgerald23 said in the first reply. I have just said it with more words!

Does it help?

Thanks David!!!
