GMATNinja, @

mikemcgarryWhy are we using present perfect 'has sent prices plunging' ? Isn't the action of 'prices plunging' over?
Little confused with the usage of present perfect in this sentence.
Thanks
Hm, good question -- I'd never really even thought about the verb tenses here, mostly because we don't really have a choice. (A), (C), and (E) all use present perfect ("has/have sent prices plunging") to describe the price drop; (B) and (D) just turn the action into a noun, so the verb tense isn't an issue in those.
So my first thought is that the question doesn't even give us the option of using simple past tense, so there's no good reason to worry about the distinction between past tense and present perfect tense in this situation.
My second thought is that present perfect seems legit enough: if the manufacturer has just announced future production cuts, then it's reasonable to say that the oversupply continues to send prices plunging.
My less-useful third thought: there's actually a lot of grey area between past tense and present perfect tense, both in real life and on the GMAT. We have a habit of saying things like "I have visited Ukraine" in the present perfect, even though the action of visiting Ukraine happened in the past. I guess we say things like that to imply that either the consequences of that trip are ongoing in the present or (more likely) to suggest the possibility that I might return there. (Because... vareniki!)
It's not hard to come up with all sorts of similar cases, in which you could choose either simple past or present perfect, depending on your stylistic choices. Here's
an official example about "dating fossils" -- in my opinion, the act of "dating" fossils should be past tense. But the official answer is in present perfect, presumably because that process of dating the fossils is an ongoing process of discovery, and scientists might eventually determine a different date. Or something like that.
The key, though, is that the GMAT won't force you to choose between present perfect and simple past unless the difference is crystal-clear. And in this particular question, the GMAT has written the question in a way that makes it a non-issue.
I hope this helps! Or at least helps you sleep at night, because that kinda got long and boring, and might put you right to sleep...
