Dear Experts,

I have a question in (A)

"once" can act as conjunction.
it means as soon as; when.

"once the grapes were pressed, the juice was put into barrels"

then why (A) is incorrect?


Well, you're right that once *can* be used as a conjunction, as in the sentence you provided. When used as a conjunction, 'once' means 'as soon as' or 'shortly after.'

But that's not how 'once' is used in the sentence as written. Here, we are using 'once' as a modifier to mean 'at one point.' The companies operated [extensive types of] operations *at one point*, but now, those companies have downsized or closed.

The sentence isn't saying, "As soon as the companies operated [extensive kinds of] operations, those companies downsized or closed.

'Once' is clearly modifying 'conducted' in the sentence.

I'm not able to understand why A is wrong and B is right. Further, why can't there be two verbs in a single clause?

Stripping out a bunch of the modifiers in (A), we're left with this:

    "The steel industry has changed, as companies once conducted operations have greatly downsized, or in some cases shut down altogether."

The part in bold is a problem. Sure, you can have multiple verbs in a single clause, but you need a conjunction to connect them (e.g. "as companies once conducted operations AND have greatly downsized"). As written, (A) is no better than saying "The companies conducted operations have greatly downsized," which doesn't work for the same reason -- there's no conjunction.

Another way to fix the problem is by turning the "once conducted" part into a modifier (e.g. "as companies THAT once conducted operations have greatly downsized"), and that's exactly what we get in choice (B).

I hope that helps!

B. as large, integrated companies, such as Bethlehem Steel, that
C. with large, integrated companies, such as Bethlehem Steel, that
D. while large, integrated companies, such as Bethlehem Steel, that
E. and large, integrated companies such as Bethlehem Steel

Here the usage of that is necessary. Let us consider choice A to understand this better. Choice A has three clauses.

Clauses:
1.The steel industry has changed radically over the last two decades,
2. as large, integrated companies such as Bethlehem Steel once conducted operations from mining at one
end of the process to shipping at the other
3.have greatly downsized, or in some cases shut down altogether.

Here, integrated companies is the subject and "conducted" as well "have downsized" are the verbs. However, if you observe closely, you would see that there is no subject for "have greatly downsized". To assign it a subject we need to ensure that the first part of the sentence should be connected by "that".

Hope this helps!

Hi all/experts,

I know the OA is (B).Not convinced ,though, by the use of that and why it is necessary in this context.

Plz Advice !!



Thanks a lot for the explanation.

Just for the confirmation that I understood your point , please advice if my interpretation per below is fine.

"X" once conducted operations from mining at one end of the process to shipping at the other [color=#005e20]have greatly downsized, or in some cases shut down altogether.[/color]

X once conducted Y from A to B HAVE VER-ed ,

So HAVE VERB-ed doesn't take X as SUBJECT ????

Thanks

Is it that with requires a -ing form?

Hi,

The key word as you have noticed is 'as', this is a close synonym for 'because'.

As is correct here because we are looking to link a statement

The steel industry has changed radically over the last two decades

With an explanation for that statement (the rest of the question).

Neither 'with' nor 'while' are appropriate here. I could go into length as to their usage, but this sort of general question is better served via google.

All the best,

James


Hello

Can you please explain in detail what is wrong with 'with' in choice C.

Comma + with serves as an adverbial modifier. Is it correct here ?

I rejected B because the comma after integrated companies is not justified. Large and integrated companies are modifiers of Benthelem Steel. There should be no comma after integrated companies, it is making the statement awkward. If we ignore the part between the commas then : as large such as Benthelem Steel is not making any sense.
please correct me here.

I am afraid you have missed out on the parsing of the sentence. ‘Large, integrated’ are co-ordinate adjectives that modify the noun ‘companies’. Since they both modify the same noun, rules allow their separation by a comma rather than being joined by the conjunction ‘and’. The comma there is not the comma that sets off inessential elements.

On the other hand, the phrase ‘, such as Bethlehem Steel,’ is a modifier that modifies large integrated companies as an example. As you know, examples are not critical mission carriers. So if you want to drop something, then you must drop the phrase ‘, such as Bethlehem Steel,’ and read further on.
B. as large, integrated companies, such as Bethlehem Steel, that
B. (revised) as large, integrated companies, such as Bethlehem Steel, that

You can see B makes sense now.



Thanks for your response. It utterly makes sense.

Can you please help me to clear one more doubt. I am always confused about usage of 'that'. If I am write 'that' can be used for singulars and not plurals. In the above question isn't companies Plural. Can you please correct me again ?

I know 'that' is correct above but please explain me when to use 'that' and when to use 'those'.

Thanks,
Radhika

I understand the subject is unclear on A, but I'm not sure I still understand the need for "that". Would B still be correct if "that" was removed as it would seem that "integrated companies" would still be the clear subject?

Reason why ‘that’ is required:

Let’s now split the sentence into the components.

1. The steel industry has changed radically over the last two decades

2. as large, integrated companies such as Bethlehem Steel once conducted operations from mining at one end of the process to shipping at the other ---subordinate clause one.
3. have greatly downsized, or in some cases shut down altogether. This clause is now dangling without proper conjugation with the subordinate clause.
Now we can see that the subject large integrated companies has two verbs namely, which is grammatically incorrect. This fault is fixed by turning the first subordinate clause into a relative noun and noun modifier, rendering ‘have ….” as the working verb for the subordinate clause. Without the 'that' , the subordinate clause will turn out to bea double - verbed fragment.

B. The steel industry has changed radically over the last two decades, as large, integrated companies such as Bethlehem Steel that once conducted operations from mining at one end of the process to shipping at the other have greatly downsized, or in some cases shut down altogether.

Could someone clarify if bold phrase could qualify "such as Bethlehem Steel"? I am not sure if the phrase points to "such as Bethlehem Steel" or to "large, integrated companies".

Thanks in advance.

It took me like 10 re-reads but I think I see what the error in B is now as I was also torn between A & B. This article covers the uses of "that":

I don't understand why there is a comma before "that" in correct answer choice. If "that" is to describe the company, Bethelehem Steel and that should not be exasperated by comma.

Appreciate your explanation very much!

Re: The steel industry has changed radically over the last two decades, as [#permalink]
My justification for correct answer B.

The First IC is followed by , - now after comma is a long under line, so it can be

modifier issue or parallelism or structure issue.

Parallelism is ruled out. Structure is maintained by using such as to present an example- ( not necessarily correct as per GMAT new rules)

so the main issue remains is modifier issue.

simplifying the sentence , after comma can be followed by another IC connected by either (; ) or by using a Conjunction.
To see if it is an IC we need to identify the subject and the verb - The subject is -- large, integrated companies, such as Bethlehem Steel,- followed by relative clause - that once conducted operations from mining at one end of the process to shipping at the other- and then the main verb - have greatly downsized -

Now to cross the subtle errors - check the Verb tense and SV agreement.
Note - If the verb was missing - using participle instead - eg having greatly downsized - then the option C would be correct as we are using a prepositional phrase instead of IC and preposition phrase cannot act as a subject and must not have a verb associated with it.
