GMAT Question of the Day – 23/3/2021

ANSWER SELECTION

ANSWER EXPLANATION

The underlined portion uses the adjective “indicative” improperly. The proper usage is indicative of, not indicative that. Here’s a correct example: This behavior is indicative of depression. But correcting this usage wouldn’t fix the sentence, because the sentence actually calls for a verb to be used, not an adjective. The author is not saying that empirical evidence is like something else but rather than empirical evidence seems to be doing something. So the proper usage is to indicate that … [one of the effects is at work].

A quick look at the choices reveals that they vary significantly, with no clear pattern or grouping. The choices are short, so just proceed to examine them more thoroughly.

(A) can be eliminated immediately, since it contains the error spotted during the initial reading of the sentence.

(B) is incorrect because it adds another, unnecessary layer of uncertainty. It makes it sound as though the empirical evidence doesn’t actually “seem to indicate” the effects. Rather, the empirical evidence seems “as if” to indicate. There is no reason for these extra words.

(D) properly pairs the adjective form of “indicative” with “of.” However, as noted above, a verb is called for here, not an adjective. (D) would have been correct had the rest of the sentence been seems indicative of either a genetic effect or a modeling effect or both. However, because what comes next is a clause with a subject and verb, what is needed is a verb plus “that” to introduce the clause.

(E) changes “indicative” into the noun “indication.” The problem is that after the word “of,” a simple noun should follow (for example, seems like an indication of success). But what follows here is a clause with a subject and verb. (E) ends up in the form seems like an indication of either X or Y is at work. This makes no sense.

(C) changes the adjective “indicative” to the correct verb form, “to indicate,” and adds “that” to introduce the clause coming up. (C) is correct.
