The subject of the main clause (such firms) presumes a prior reference to the firms in question. Furthermore,
the logical subject of to survive and the logical complement of required should be made explicit. All three
demands are met by B, the best choice. Choices A, C, and D, with no reference to the firms in question, meet
none of these demands. In choice E, the illogical and awkward use of a prepositional phrase (for firms' survival)
buries the needed initial reference to firms in a possessive modifier.

Hi thangvietnam,

Let us recollect the pronoun rule: A possessive noun is not a good antecedent of a pronoun. e.g.,

The teacher is rechecking John's research thesis to determine whether he has used his original idea.

John's is not a good antecedent for he because of the above rule.

Please note that the word such combined with a noun is used to refer to an antecedent mentioned previously. The antecedent in this case also should preferably not be in possessive. For this reason the possessive firms' is a poor antecedent of such firms.

Is this explanation satisfactory?

Because of the enormous research and development expenditures required to survive in the electronics industry, an industry marked by rapid innovation and volatile demand, such firms tend to be very large.

'Such firms' need a reference in the sentence. hence, only B fits in here.

Logic + Modifiers

A, C, and D can be eliminated because they give a meaning that “enormous research and development expenditures” are required of the ‘industry’. The correct meaning is that such enormous expenditures are required of firms to survive in the electronics industry.
E is wrong because it also fails to convey the meaning effectively.
B is the best choice.

As far as i know, the correct idiom structure is "require + noun + to", but still i am not able to understand how option B is correct answer.
Dear Fame,
The correct idiom for the active use of the verb is -----require + [noun] + [infinitive] ----
ACTIVE FORM: Firms require enormous research and development expenditures to survive.
This sentence is NOT using the verb "to require" in its active form. Instead, it is using the past participle form, "required", as a participle modifying the noun phrase "enormous research and development expenditures." The rules for the past participle follow the rules for the passive use of the verb. For many verb, the subject in the active form would become the object of the preposition "by" in the passive form ----
I read the book. ----> The book was read by me.
Idiomatically, the preposition "by" sounds unnatural with the passive verb "required" in this particular construction. Because the former subject, here "firms", is now essentially the subject of an infinitive phrase, it must take the preposition "for" --- the preposition "for" is the preposition we use to denote the subject of an infinitive or infinitive phrase.
I want for the teacher to help you.
For a homerun hitter to hit over .300 is a notable achievement.
The lawyer argued that it was not a crime for a policemen to use deadly force in an ambiguous situation
.
When we change the active form above to passive form, the former direct object, "enormous research and development expenditures" becomes the subject (that always happens in a change from active to passive), and because we still have an infinitive phrase, the former subject, "firms", becomes the object of the preposition "for", becoming the subject of that infinitive phrase:
ACTIVE FORM: Firms require enormous research and development expenditures to survive.
PASSIVE FORM: Enormous research and development expenditures are required for firms to survive.
Now, we are ready to consider the sentence in this question. The past participle, "required", follows the rules & structures of the passive form of the verb "are required."
Because of the enormous research and development expenditures required for firms to survive in the electronics industry, an industry marked by rapid innovation and volatile demand, such firms tend to be very large.
That's (B), the OA version of the sentence.

Does all this make sense?
Mike :-)

Sir, is it a typo error ? In option B ' OF FIRMS' instead of ' Required FOR FARMS to survive' as suggested by you.

Because of the enormous research and development expenditures required to survive in the electronics industry, an industry marked by rapid innovation and volatile demand, such firms tend to be very large.
(A) to survive
(B) of firms to survive
(C) for surviving
(D) for survival
(E) for firms’ survival

The last part of the sentence uses "such firms" which will need an antecedent in the earlier sentence.

So A,C, D are out.

"firms' survival" is possesive and "such firms" can't refer back to it.

Thus B
But such firms are not a pronoun so why it requires a clear antecedent?

Hi Mike,

in the following :

Despite protests from some waste-disposal companies, state health officials have ordered the levels of bacteria in seawater at popular beaches to be measured and that the results be published.

(A) the levels of bacteria in seawater at popular beaches to be measured and that the results be
(B) that seawater at popular beaches should be measured for their levels of bacteria, with the results being
(C) the measure of levels of bacteria in seawater at popular beaches and the results to be
(D) seawater measured at popular beaches for levels of bacteria, with their results
(E) that the levels of bacteria in seawater at popular beaches be measured and the results

ordered is in participle for still we follow the subjunctive rule ... I know it has to do something with "order" being a command subjunctive and "require" is just a punk which can be anything, take "that" after it, take "to+verb" after it and in the quoted explanation of yours I got to know it dont need these too, it can be a participle and can get rid of TOs and THATs

show me light mike ...
Dear stunn3r,
I would like to help, but to some extent I am having trouble following your question.

In the quoted SC problem, in which OA = (E), "ordered" is not a participle. No, "have ordered" is a full-fledged verb --- in fact, it's the main verb of the whole sentence! If we put the verb in its present participle form, "ordering", then the present participle is active, so this could still take a "that"-clause with a subjunctive.
The senator ordering that the teenagers be charged with a felony will be censured by his peers..
The past participle, "ordered", is passive, so it would modify an order or command, not the person giving it, and thus we couldn't fit a "that"-clause into that structure.
The moratorium on judicial appointments, ordered by the Supreme Court, is likely to extend through the summer.
If we used "ordering" as an gerund, it would take the same structure
In ordering that the banks remain closed, the governor drew the ire of the populace.
As a general rule, any verb keeps all its associated idioms in all of its forms --- not only all tenses, but all verbals (infinitives, participles, gerunds). Many times, the same idiom remains even when we change from the verb form to the noun or adjective form of the same root word
A differs from B.
A, different from B, ...


The verb "require" can take a couple different idioms, but let us not cast aspersions on it. This variety is precisely what allows for creative expression in a variety of forms. Creative expression is one of the many ways in which you can impress others with your intelligence through writing. That's a good thing!! :-) The verb "require" keeps its idioms in its various forms.
The judge required the striking workers to return to work.
The judge required that the striking workers return to work.
The striking workers were required to return to work.
The judge requiring that the striking workers return to work was passed over for appointment to a Federal Court.
In requiring that the striking workers return to work, the judge alienated the unions.
In requiring the striking workers to return to work, the judge alienated the unions.
To require that striking workers return to work is not within the powers of a county judge.
To require striking workers to return to work is not within the powers of a county judge.
(slightly awkward, only because of all the to's)
A return to their jobs, required of the workers in court, financially helped the individual workers but broke the spirit of the union.
All of these are correct sentences.

Does all this answer your question?
Mike :-)


As per my understanding from various sources

in the case of passive form we normally use require + infinitive, but in the case of active form we use the subjunctive form, which is require +that+ simple form of verb.

The judge required the striking workers to return to work.
The judge required that the striking workers return to work.

After seeing those statements, i am confused regarding the usage of require.

Can you please explain this part in detail.

mahi816 In the cases you're citing, "required" is the verb. In this sentence, "required" is an adjective modifying "expenditures." To get the idea, we could replace "required of firms" with "needed by firms":

Because of the enormous expenditures needed (by firms) to survive in this industry, such firms tend to be very large.

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.

(A) to survive -> It seems correct. As something required to survive. But in non-underlined part, "such firm" needs a reference in 1st clause as well. Incorrect.

(B) of firms to survive -> It is better than A. Let's keep it.

(C) for surviving -> Doesn't have reference for "such firms". Incorrect.

(D) for survival -> Same as C.

(E) for firms’ survival -> to survive is better choice. Incorrect.

So, I think B. :)

The mention of 'such firms' later in the sentence tells us that there must be a reference to the firms earlier on in the sentence. For this reason, A, C, and D are out.

Between B and E, B wins because it clearly mentions the firms for 'such firms' to refer back to this later on. In E, only the firms' survival is mentioned - not the firms themselves - so 'such firms' has no precedent to refer back to.

Clearly B.
BUT OG says required of X to do Y is INCORRECT ...

Legislation in the Canadian province of Ontario requires of both public and private employers that pay be the same for jobs historically held by women as for jobs requiring comparable skill that are usually held by men.
(A) that pay be the same for jobs historically held by women as for jobs requiring comparable skill that are
(B) that pay for jobs historically held by women should be the same as for a job requiring comparable skills
(C) to pay the same in jobs historically held by women as in jobs of comparable skill that are
(D) to pay the same regardless of whether a job was historically held by women or is one demanding comparable skills(A)
(E) to pay as much for jobs historically held by women as for a job demanding comparable skills

Choice A is best. In choice B, should is illogical after requires, or at least unnecessary, and so is better omitted;in choices B and E, job does not agree in number with jobs; and in choices B, D, and E, the wording illogically describes the comparable skills rather than the jobs as being "usually held by men." Choices C, D, and E produce the ungrammatical construction requires of... employers to pay, in which of makes the phrase incorrect. In C, the use of in rather than for is unidiomatic, and jobs of comparable skill confusedly suggests that the jobs rather than the workers possess the skills. In D, the phrase beginning regardless ... is awkward and wordy in addition to being illogical.

Hey buddy I'll answer this one. The usage of the word 'require' in the question you posted is different from the question here.

The question you posted about the province I live in (yay Ontario!) states that the legislation 'requires' something, which is a demand that can only be adequately expressed in the subjunctive form 'verb in any tense + that + simple form of another verb' = 'REQUIRED that wages BE the same'.

However, in this question about firm's survival, 'required to survive' is using the verb 'require' as a 'necessary' condition for survival, an objective description. No one is demanding anyone else to do something. Hence the form 'verb + infinitive of another verb' is fine, and the use of subjunctive form would be wrong;

edit: I just realized that I replied a post from 10 years ago...I must be crazy...but i'll leave it up here anyway for others who either might be wondering about the same thing or kind enough to point out where I may be wrong.

Hi mikemcgarry -

Thank you for the valueable information and all the efforts made by you to guide the students.
The explanation given above by you is concludes that Option B is correct and the usage - Required for firms to survive is the correct form , highlighted below for your reference.

Because of the enormous research and development expenditures required for firms to survive in the electronics industry, an industry marked by rapid innovation and volatile demand, such firms tend to be very large

However, option B says required of firms to survive.

can you please help to clarify the confusion b/w required for and required of?

thanks

Hello Tanchat,

We hope this finds you well.

To answer your query, "the enormous research and development expenditures required of firms to survive" simply means "the enormous research and development expenditures that firms need to survive".

We hope this helps.
All the best!
