If the statements above are true, which one of the following must be true?
(A) Not all of those who are humorous observers of the commonplace will be heard by the next generation.
(B) Everyone who will be heard by the next generation keeps a journal.
(C) The next generation will hear both insufferable egotists and true artists.
(D) Some of those who keep journals are not true artists, humorous observers of the commonplace, or insufferable egotists.

The question has been asked before and most people voted for C.
But why not D? Why, as some say, is it out of scope? The argument does not indicate that the three categories are exhaustive. Wouldn't that mean that some people have not been categorized?

First of all, 1000 series have multiple mistakes in answer choices, so don't be shy to think logically and prove your answer choice.

Let me try.

The main statement is: Next generations WILL hear ALL who keep journals. - it is strong statement and narrows down the scope of argument.
Paraphrase it: If you have a journal than next generations will hear you, if you don't they will not hear you.
Among those who keep journals are: true artists, humorous observers and nsufferable egotists.
Ok so far?

Lets see how can we eliminate the answer choices.

All those who keep a journal will be heard by the next generation. Some of these journal writers are true artists, others humorous observers of the commonplace, and still others insufferable egotists who feel compelled to record their every thought.
If the statements above are true, which one of the following must be true?
(A) Not all of those who are humorous observers of the commonplace will be heard by the next generation. - false, as we know that "If you have a journal than next generations will hear you, if you don't they will not hear you "
(B) Everyone who will be heard by the next generation keeps a journal. - it this trick, it is reversed statement that is not necessarily true. Too strong, "everyone"
(C) The next generation will hear both insufferable egotists and true artists. - wou really ?! what if they don't have any journal? Observe that official answer choice is wrong here.
(D) Some of those who keep journals are not true artists, humorous observers of the commonplace, or insufferable egotists. yes! bingo. Remember the statement "Among those who keep journals are: true artists, humorous observers and nsufferable egotists." of course there are other people who keep journals.
(E) The next generation will bear some of those who are true artists but not all of them. false, as we know that "If you have a journal than next generations will hear you, if you don't they will not hear you "

I picked A initially and not convinced with the OA.

Pkit, just wanna discuss y the A option is wrong..
As u pointed out, the main statement is: Next generations WILL hear ALL who keep journals. Means all those who keep journals would be heard by next generation. But nowhere is in passage, it is applied that ALL humorous observers of the commonplace keep journals. Hence, there are some humorous observers who DO NOT keep journals.

Now, looking at the option A, it says NOT ALL of those who are humorous observers of the commonplace will be heard by the next generation. Isn't this correct? Can u pls explain why should we not choose A as the right option??

thnx..

Hi I think the OA C is correct.
The stimulus mentions explicitly that some of those who maintain a journal are true artists and some are insufferable egotists in all probability with 100 % guarantee.The Answer choice nowhere nowhere says that The next generation will hear all insufferable egotists and true artists.
So your question can be eliminated what if they don't have any journal?
As for D , the Powerscore Cr says that in a Must be True quest, we are not supposed to bring any outside information

Dont agree.

All those who keep a journal will be heard by the next generation. Some of these journal writers are true artists, others humorous observers of the commonplace, and still others insufferable egotists who feel compelled to record their every thought.

Some - means that there are other people except for true artists, others humorous observers of the commonplace, and still others insufferable egotists.

C is too strong (will)
В - is soft.

В - is soft.

So Now , we have to get this sentence interpreted by some Verbal expert.
AFAIK, the the 1st clause is independent of the the other 2 phrases.
Some is only in the first independent clause and has no influence on the other 2 phrases.
Had the first been a phrase then i think the Some will have an influence on the other 2 phrases

To me both C and D are worth a look.

Pkit's explanation why C is wrong would be spot on if C were something like "The next generation will hear ALL insufferable egotists and true artists." However, since we do not have this word in there and we know that some journal writers are insufferable egotists and true artists, then C is true to me. The way it's spelled out right now, I feel like we should interpret it along the lines of "The next generation will hear SOME insufferable egotists and true artists." I may be wrong, or the answer choices are not that well written?

D also looks true because the stimulus does not seem to be exhaustive in nature. It doesn't say: hey, you know what, all those that keep a journal fall into one of these three categories.

I would disagree with Intern & PKIT. Clearly C is the correct answer.
For Contrapositive of 'Some A are B', is 'Some B are A' and not 'Some A are not B'. It is possible that Some A are not B but same cannot be said with certainty. eg. If I say some balls are red, it does not mean that some balls are not RED. I do not know if there are any balls other than RED.

It is clearly C.

D is not necessary true because all the journals could be either true artists, humorous observers of the commonplace, or insufferable egotists.

C is necessary true because there are journals, who are egotists and true artists, that will be therefore heard by the next generation.

Please tell me if that helped or you need further explanation.

(E) The next generation will bear some of those who are true artists but not all of them. false, as we know that "If you have a journal than next generations will hear you, if you don't they will not hear you "

After some time and with a fresh look, I think C is the Best answer!

The key here is the first sentence of the passage:
All those who keep a journalwill be heard by the next generation

Since it says that the next generation will hear EVERYBODY who keeps a journal, and we know that of those who keep a journal some are true artists, humorous observers of the commonplace, and insufferable egotists.

from here we can be sure that (C) The next generation will hear both insufferable egotists and true artists
