Dear
IanStewart I failed to find fault with the wording of choice E. Could you please help sort out my doubts below?
1. Whether the phrase “firms’ survival in the electronics industry” clearly illustrates that firms are from this industry?
2. I am aware that a pronoun can refer to a possessive noun, but not sure whether
such firms can refer to
firms’ ? If the answer to my first question is “yes”, then to the second must be “yes” either, isn’t it?
3. I eliminated E only because it doesn’t clarify whom enormous expenditures are required of. If it were something else, then there would be no reason for such firms to be very large. Are there any other valid reasons?
Your thoughts are much appreciated. Many thanks beforehand.
To #1, I'd say yes, to #2 I'd also say yes, and to #3, I'd say you eliminated E for the right reason.
There's a lot of discussion above about whether pronouns can refer to possessives. Maybe it's preferable if they don't (especially in more complicated sentences), but that's not a criterion I would use to eliminate an answer choice on the GMAT. In this sentence, say:
Ajike's time is limited, so she won't attend the meeting today.
we could rewrite it as follows:
Ajike has limited time, so she won't attend the meeting today.
but I don't see any reason to prefer the rewrite to the original. It's clear who "she" refers to in both examples.
It's true in many SC questions that more than one answer will be grammatically acceptable, but one will still be better than the rest. That's how I feel about B and E here. In most cases, in good writing, we usually* want to be clear about who is doing what. In this sentence, in the first clause, we want to be clear about who is bearing the "enormous research and development" expense. Answer B makes that crystal clear, but answer E does not. So B is better writing than E.
*I say 'usually', because there are exceptions. Sometimes the object of an action is more important than the subject, and in such cases, it might be preferable to be unclear about the subject, or to use a passive construction. So a sentence like "After the 1899 littering law was enacted, the streets were much cleaner" is fine, even though the first half is passive, because the sentence means to draw attention to the law itself, and not to who enacted the law.
