Dear
tuanquang269,
I'm happy to respond.

Always fun to answer a question I have written!
This is a question about the
Book of Kells, one of my favorite art works in the world!
Split #1: listing examples. For examples, we need to use "
such ... as," and not "
like." Choices (A) and (B) are wrong on this count, and choice (C) is questionable. Choice (D) and (E) have the correct structure.
Split #2: parallelism. The first main verb is "
demonstrated." We need the second verb to be in parallel with this, "
incorporated," not "
incorporating" or "the
incorporation."
All this is enough to isolate
(E) as the only possible answer.
Does all this make sense?
Mike
