SPOILER | Power prep 2 TC 3 blanker

In this question, I did the first 2 blanks successfully with Support/Contrast. But I do not get how G is correct for blank iii.

My method for blank iii).

  1. The sentence “knowledge of the … your subject becomes” is support with the first sentence because of the colon.
  2. Sentence before the colon, says that the history research makes truths that were considered banal to seem profound.
  3. So, that should mean that “more material you uncover, the more revealed the subject becomes”

So i choose circumstantial, for “in great detail”,
I thought that G. elusive is contradictory because of the first sentence “history research makes truth considered banal to seem profound”.

I dont understand where the clue for elusive is .
Please help me
