OE
The last part of the sentence makes a distinction between the fact of genetic modifcation and the particulars of how this modifcation is done. This distinction is made in order to support the sentence’s implication that consumers who believe that genetic engineering itself is new are mistaken. Therefore, the distinction must relate to what about genetic engineering is in fact new, so the blank must be completed with words that are synonymous with “newness.” Both “novelty” and “innovation” ft this description, and the pairing produces sentences alike in meaning, so it is the correct answer. Of the other responses, while “quandary” and “predicament” are synonymous, nothing in the rest of the sentence mentions the problematic aspects of genetic engineering; therefore they do not ft the meaning of the sentence as well as the correct pairing. “Advantage” has no synonym among the choices, nor does the passage otherwise mention genetic engineering’s benefts. “Discrepancy” likewise has no synonyms among the choices; it also does not describe the subject of the distinction made in the latter half of the sentence.
Thus the correct answer is novelty (Choice A) and innovation (Choice D).
Answer: A,D
