Dear Experts,
GMATNinja AndrewN GMATGuruNY IanStewart ReedArnoldMPREPIs it possible to use "this" in this context?
I cannot remember exact OG questions, but I have seen many times that many experts in GMAT CLUB eliminate choices with "this" without another noun.
There must be a noun following "this". Why is (C) correct?
I understand that there are other clues to eliminate other choices but I would like to know how "this" can and cannot be used.
I don't think it does make sense to eliminate choices with "this" alone in other OG questions but cannot use the same logic as this question
Hi
Tanchat,
Here are my thoughts on
this (
original post here):
Generally, in EnglishThe usage of
this to refer to some person, event, or thing mentioned in the sentence (or even outside the sentence:
Don't do this) is acceptable. Here are a few examples:
1.
He studied at Stanford, and this allowed him to develop the network that he needed.2.
Companies in the area want MBAs; we know this because we've spoken with them.3.
Electric cars are generally quite expensive, but this is not.4.
You should take accounting and marketing as these are the most important for you. (
these is the plural form)
Such usage is allowed in English, but may not be very precise. For example, in (3), the
one after
this is understood:
3a.
Electric cars are generally quite expensive, but this one is not.or
3b.
Electric cars are generally quite expensive, but this electric car is not.Similarly, in (4), the sentence assumes a word like
subjects:
4a.
You should take accounting and marketing as these subjects are the most important for you.An interesting point here is that
that and
those are much more common than
this and
these in such constructions (something like 10:1 if I remember correctly). For example, we can generally expect people to prefer
1a.
He studied at Stanford, and that allowed him to develop the network that he needed.to
1b.
He studied at Stanford, and this allowed him to develop the network that he needed.and
4b.
You should take accounting and marketing as those are the most important for you.to
4c.
You should take accounting and marketing as these are the most important for you.Quote:
DNA evidence was recovered by scientists, who were able to deduce from this that an epidemic of malaria struck in the empire’s waning days.
Perhaps the sentence is assuming a word like
discovery here:
DNA evidence was recovered by scientists, who were able to deduce from this discovery that an epidemic of malaria struck in the empire’s waning days.On the GMATSuch usage is vague, but I would not go so far as to say that it is "unacceptably vague". It is, however, a very good sign that the option we're considering is incorrect. All in all, I'd advise you to use it as just that: a sign. Be aware of this concept, use it, but don't put it all the way up there with something like SVA.
