Empowergmatverbal mentions the following "D. not only an examination about the difficulty with reconciling reason, will, and passion together in any art form, but also a skillfully navigated exploration of the major concerns of modernism
This one is tricky, but it is also NOT PARALLEL because the phrases ???an examination about??? and ???a skillfully navigated exploration of??? are not parallel ??? they both need to say ???about??? or ???of??? to work. Therefore, this is also INCORRECT."
Wouldn't it be incorrect to say "about" for both?
"not only an examination about the difficulty" seem unidiomatic and awkward. In my view, it should be " not only an examination OF the difficulty"
Thank you!
