Great response! Thanks for bringing this post back to our attention. We should have a complete explanation up, so here goes.
Question Type: Inference - Must Be True EXCEPT
Task: Eliminate the four answers that Must Be True. When we read Inference, we’re not looking for arguments. We’re just trying to understand the facts and synthesize ideas where possible.
(A) To say "the crux of creativity resides in ability to manufacture variations on a theme" means that "the ability to manufacture variations" is the defining feature of creativity. By that rule, (A) must be true. The MORE you’re able to manufacture variations, the MORE creative you are; the LESS you’re able, the LESS creative you are.
(B) The second sentence proves this answer choice. "EVERY idea in the history of science is built upon a thousand related ideas". We could rephrase that as (B) does, saying NO idea is entirely independent of all other ideas.
(C) This is weakly worded, very easy to support. The last sentence says that "Careful analysis" leads us to understand that new ideas are always variations on a theme. In order for careful analysis to tell us this, it must be true that we discovered the previous theme for any new idea (how else would we have established that the new idea was a variation on a previous theme?).
(D) The last sentence tells us that "new discoveries" are "always and without exception" some sort of variation. Therefore every discoverer (one who makes a discovery) must have manufactured a variation on a theme. Critically, this answer choice doesn’t accuse the discoverer of KNOWING that he/she manufactured a variation. That would go beyond what we can prove.
(E) Correct answer
This contradicts the last sentence, which says that EVERY SINGLE discovery ALWAYS AND WITHOUT EXCEPTION is a variation on a deep level of previous themes.
