Here's the
official explanation provided by the GMAC for this question:
The sentence provides examples of American singers not working within the classical-music tradition and places their work within a rich tradition originating with ragtime. The key issue is how best to cite examples of the class
America’s nonclassical singers. With the word
figures, which occurs in all the answer choices, the correct idiomatic form for doing so is
such figures as, rather than
such figures like.Option A: The form
such figures like is not idiomatic.
Option B: The form
such figures like is not idiomatic. Furthermore, this wording conveys an unintended meaning, namely that America’s nonclassical singers are just the three named. It oddly suggests that the
figures in question merely resembled America's three nonclassical singers and were not themselves among those singers.
Option C: The singular
a figure does not fit with the plural
singers.Option D: This conveys an unintended meaning, namely that America’s nonclassical singers are just the three named. The use of
like to cite examples of a class is acceptable in casual speech, but it is ambiguous between
similar to and
such as, so the latter is usually preferable in more formal contexts. Here, use of
like is inappropriate and implies that there may have been singers who are not among
America’s nonclassical singers but who resemble them and work within the rich tradition described.
Option E: Correct. The locution
such figures as is idiomatically used to cite examples of a class.
The correct answer is E.
