Im kinda surprised that they would solely test for such a thing. (i.e audio)
I believe SUCH AS is to give examples and LIKE is something that is similar.

Sentence Correction is primarily a test of LOGIC, not grammar. So it's not enough just to follow modifier rules - we need to ask if it's logical for one thing to modify another. I tend to agree with you that this question (which is from Economist GMAT) is pickier about classifications than any I've seen on the real GMAT. It's not outside the realm of a reasonable meaning test, though, in my opinion.

As for the SUCH AS v. LIKE issue... you're correct about what the GMAT has tested in the past. But! We have brand new information from OG 2017 that indicates that the GMAT changed its mind about this idiom! See here:

"In question 685, though, the non-underlined portion uses the word like to mean for example. Further, there are no questions in either OG 2017 edition SC chapter that specifically make you choose between like and such as. (Not purely. There's one that does have these words, but the issue there is a little different...it makes you choose not between such as and like but between such as and such like. Such like is...not a real phrase.)

What does this mean? Language does change over time, and, currently, people do use like to mean for example. So I'd guess that we don't need to worry about this particular issue any longer. (Though, again, such like is not an idiom. )"
