"what xxxxx" is by default singular; i was going to produce the same question (caves at lascaux) that iongmat just produced here.

in fact, i don't think that "what concern them" could ever be correct; i'm pretty sure that "what" is always singular, unless it's in a question (e.g., What are the two most important things in your life?) -- but GMAT SC doesn't test questions, so that exception is immaterial here.

yuk, i'll make sure we fix this sentence soon.

note that the parallelism in this problem has been transcribed incorrectly -- there should be "that" in front of "the seas will..." (which the poster forgot to transcribe -- important, because that transcription ruins the parallelism).
so that appears to be wrong here, too, but that's the poster's fault. however, that first mistake is pretty awful -- we'll get that out of there.

sorry! someone fell asleep on this one ... it happens. we'll fix it

What my wife brought was my hat and my gloves.

However, the following sentence from MGMAT confuses me:

What concern scientists the most about global warming are the risks that the polar ice caps will melt, the seas will grow too warm to sustain marine life, and that violent weather patterns may result.

What I think is:

1. The sentence should read What concerns scientists the most about global warming. Basically there are many things that concern the scientists; out of all those things, clearly there must be something that concerns them the most. You cannot have many things concerning you the most.

2. Since the sentence starts with a noun clause, the noun clause should be singular and so, the correct sentence should be:

What concerns scientists the most about global warming is the risks..

Request Ron Sir or some esteemed MGMAT instructor to clarify the doubts.

There seems to be as much debate out there as there has been here. Some grammar sources claim that a plural verb can be assigned to a subject clause under certain circumstances; interestingly, I haven't found a definitive source that says it can never be done. Yet every time I read subject clause + plural verb, the construction offends my ear. I myself never would say what concern scientists or what my wife brought were.

as a seasoned professional writer, i would bet good money that these sources are either (a) subpar or (b) non-american, or that they are talking about subject clauses that don't conform to the type discussed here.

yeah ... good look on finding that thread; i went ahead and deleted it, because we're going to kill this problem as soon as we have the time to edit it.

that problem is many years old, and was written by someone who is definitely not writing problems for our company anymore. |:
