Although many art patrons can readily differentiate a good debenture from an undesirable one, they are much less expert in distinguishing good paintings and poor ones, authentic art and fakes.
(A) much less expert in distinguishing good paintings and poor ones, authentic art and
(B) far less expert in distinguishing good paintings from poor ones, authentic art from
(C) much less expert when it comes to distinguishing good paintings and poor ones, authentic art from
(D) far less expert in distinguishing good paintings and poor ones, authentic art and
(E) far less the expert when it comes to distinguishing between good painting, poor ones, authentic art, and
Choice A: In Option A, we see the use of the incorrect idiomatic form "distinguishing X and Y" in the phrase "distinguishing good paintings and poor ones, authentic art and fakes". Thus, Option A is incorrect.
Choice B: Option B preserves the intended meaning of the sentence and utilizes the correct idiomatic form. Thus, Option B is correct.
Choice C: Option C commits the same error found in Option A. Moreover, the phrase "expert when it comes to" is needlessly wordy. Thus, Option C is incorrect.
Choice D: Option D also repeats the error found in Option A. Thus, Option D is incorrect.
Choice E: In Option E, we see a distortion of meaning arising from the use of the phrase "distinguishing between"; the intended meaning of the sentence is that while many art patrons can distinguish between a good debenture and an undesirable one, they are less capable of distinguishing between good paintings and poor paintings and between authentic art and fakes. However, if Option E is utilized, the resultant sentence lists all four elements in one list; this change alters the sentence to mean that the patrons are not as capable of distinguishing between all four elements taken together, as they are capable of differentiating between a good debenture and an undesirable one. Thus, Option E is incorrect.
Hence, B is the best answer choice. To understand the concept of “Use of Distinguish on the GMAT”, you may want to watch the following video (~1 minute):
