OE Magoosh:
Split #1: the example of "prey." On the GMAT, when we are giving a noun and then a list of examples of the noun, the correct way to introduce this list of example is with the words "such as." The word "like' is 100% wrong (be careful: this mistake is common in colloquial English, which is precisely why the GMAT tests it!) (A) and (C) have the incorrect form "like." Choice (D) has the awkward structure "prey, for example, Himalayan Blue Sheep" --- this structure will not be correct on the GMAT either. Only (B) & (E) are correct on this one.
Split #2: how scarce? The structure "so scarce that" is perfectly correct and elegant: this is what (B) & (C) have. By comparison, the structure "of such scarcity that", while grammatically correct, is wordier, less concise: this is what (A) & (D) have. This latter structure would be more appropriate for a noun that didn't have a convenient adjective form: "of such quality that." The structure in (E), "as scarce as to" is wrong: this conflate the two correct patterns: (i) "so [adjective] as to [action]" vs. (ii) "as [adjective] as [noun]."
See this blog for more on the "so" idioms.Split #3: We need what follows "that" to be a bonafide [noun] + [verb] clause. The subject, "a range", is singular, so the verb must be singular. (A) & (C) have the plural verb "support", which is wrong. Choice (B) is the only one with the singular "supports", so that the word "that" is followed by a proper [noun] + [verb] pair. Choice (D) has "supporting," a participle, so there's no verb at all for the "that" clause: this is a classic mistake, the "no verb" mistake. Choice (E) has the strangely informal "make a range … supporting" --- using "make" for a situation is a colloquial construction that would never be correct on the GMAT, so this is completely wrong.
For all these reasons, the best answer is (B).
