Is it A and D?

Sorry guys,

along with the questions from PowerPrep there is always an official explanation. Only the time to elaborate it. Thank you for your patience.

Back to the question

Unadorned: to decorate or add beauty to, as by ornaments
harmonious: marked by agreement in feeling, attitude, or action
multifaceted: having many facets, as a gem
inalienable: not transferable to another or capable of being repudiated
exigent: requiring immediate action or aid; urgent; pressing
extraneous: introduced or coming from without; not belonging or proper to a thing; foreign

As you can see from the meaning of the words above, the only two that fit into the question are C and F

In a nutshell: the nature of Athens tragedy to our modern view is multifaced. However, in its real core it was sooo consistent and solid that the tragedy itself endure the time unfolding, during the centuries. In conclusion, the same importance of tragedy, its caliber, its influence to the generation ahead is unassailable, absolute, unequivocal.

Hope this helps. Ask if something is unclear to you.

PS: as yu can see, a GRE question is really subtle in its meaning.
