"Some" can be a confusing word in CR questions. The correct logical translation of some is "at least one". There is NO upper limit on some - in other words, "some" could mean "all".

In the above question, the only choice that MUST be true is (c). We know that ALL journal keepers will be heard by the next generation and we know that some journal keepers are true artists and/or insufferable egotists. Therefore, we know that at least those true artists and insufferable egotists who keep journals WILL be heard by the next generation.

thanks, stuart

Hi Stuart,

Can you please provide an explanation for eliminating each of the other incorrect options?
It will be most helpful.

Thanks

Sid

Why E is wrong ??

Let me try to explain all the options:

(A) Not all of those who are humorous observers of the commonplace will be heard by the next generation. - We know that some of the humorous observers keep journals, but we they could be the only one who are humourous observers. As Stuart mentioned, 'some' could mean 'all'. Hence this statement may or may not be true.
(B) Everyone who will be heard by the next generation keeps a journal. - The passage says that everyone who keep journal will be heard by next gen. But there could be more people who could be heard by next gen.
(C) The next generation will hear both insufferable egotists and true artists. - As some of the people who keep journals are insufferable egotists and some of them are true artists, The next gen will surely hear both of them.
(D) Some of those who keep journals are not true artists, humorous observers of the commonplace, or insufferable egotists. - We do not know this from the passage. There could be none.
(E) The next generation will bear some of those who are true artists but not all of them. - Again, we can not say for sure whether only some of the true artists keep journal (and hence would be heard by nex gen) or all.

Hope this helps.

many thanks that was very good

I think E has a scope shift of "bear". When all that is mentioned in the passage is "heard" by the next generation.
