Please underline the portion of the sentence to be changed.

The verb needs to agree with substances (not one) and be in present simple tense (because we are talking about a persistent, general truth). This leaves answer choices A and B. B is worded awkwardly, using at which time instead of simply saying when. Also, B uses both... or..., though it should be both... and....

Therefore, I would choose answer choice A.

There is a simple clue that will do the trick. The clue is the word ‘both’, which acts as the first part of the correlative conjunction - both…. and, to describe two events, namely, when to become and when to remain. It implies therefore that any choice using the conjunction ‘or’ is out of way; B, C, and D are gone. Between, A and E, it does not take much time to eliminate E, what with E being ridden with so many flaws such as the unidiomatic ‘both about’ and the use of the future tense ‘will’ for an eternal fact.

The other route is to remain committed that the subordinate verb is tell, following a restrictive pronoun ‘that’ and then choose A over B for reasons of concision.

The very easy sentence challenges us the usage of parallel idiom BOTH x AND y. Only choice A matches this rule. We just scan through all at But, and, or words.

Guys,

I would suggest all of you to refer to the MGMAT forum to clear this doubt.

http://www.manhattangmat.com/forums/sin ... t1400.html

"One of the" construct is NOT always considered singular. Many of the answers in the 1000 SC collections are not correct.

Correcting my statement (Adding a NOT which i missed earlier and changed the whole meaning. ... sorry for the confusion.

Thanks!!

Quote:
"One of the" construct is always considered singular.

I am afraid one cannot justify such a wide remark. You may refer to Stacey’s observation in the link you have cited.

Quote:
Your middle sentence has a different structure. Here's the core of each:

1) One of the ethnic groups was (main subj=one, main verb=was)

2) A higher interest rate is only one of the factors that keep (main subj=rate, main verb=was. THEN "one of the factors that keep" is a subordinate clause - the "that" indicates a noun modifier, so it refers to the noun right before it - "factors")

3) One of the students was (main subj = one, main verb = was)

So the question is what noun to match with what verb. In a sentence in which you have a straight "one of the noun verb," one is going to match with that verb. In a sentence in which you have "noun verb one of the noun THAT verb" the verb is going to go with the noun immediately preceding the word "that."

You may thus see it is not always that 'one of the construct' is singular, as you have mentioned. Secondly, in this present example, you see the prevalence of the subordinate clause introduced by the noun modifier ‘that’ . So the verb is going to be plural in this case, namely ‘tell’ rather than the singular ‘tells’.

Am I right?

hey i studied Stacey's explanation on the forum. But still not very clear as to when consider one of the as singular and when to consider it plural.

@daagh: can you please give a detail explanation?
It would be really very helpful
Thanx

Consider these examples.

One of the books in the rack has been written by Irving Wallace

This is a simple sentence with ‘one ‘as the subject, of the books as the prepositional intermediary and ‘is ‘as the verb. In this case, the subject and the verb are singular.

Look at the next case. One of the books that have been written by Irving Wallace is in the rack. --- here the main clause is ‘one of the books is in the rack’ and the subordinate clause introduced by the relative pronoun and the conjunction is ‘that have been written by Irving Wallace’. The verb of this subordinate cluse will be plural, since the relative pronoun refers to the noun before and takes on its characteristics such as number and gender. Hence, the subject of the subordinate clause is plural in nature and the verb is plural.

This is what Stacey says according to me. In other words, whenever you see a relative pronoun such as that or who etc, in a complex sentence that contains ‘ one of the construct’ , be guided by the number of the noun it touches for determining the number of the verb.

For this sentence, 'one of the substances' is not singular. If we take a closer look we are describing substances. Which substances? The ones that 'tell individual...' Therefore, we can eliminate (C), (D). (We can get rid of (E) because the future tense is not required; the 'it' is wordy).

The idiom is BOTH X and Y. (B) has BOTH X or Y. Thus the answer is (A).

Hope that helps .

Biologists believe that they have found one of the substances that tell individual genes both when to become active and when to remain quiescent in the earliest phases of an embryo’s development.

clause initiators which-nonrestrictive- and that - restrictive - depends on the context of sentence. THAT IS used as a function word immediately before or after a word group consisting of a verbal auxiliary or a form of the verb be preceded by there or a personal pronoun subject to indicate emphatic repetition of the idea expressed by a previous verb or predicate noun or predicate adjective

usully the formula is to take the one after eliminating the "of" construction...but "it" depend on meaning of the sentence
take this one.

In the mid-1920s the Hawthorne Works of the Western Electric Company was the scene of an intensive series of experiments that would investigate changes in working conditions as to their effects on workers' performance.

(A) that would investigate changes in working conditions as to their effects on workers' performance
(B) investigating the effects that changes in working conditions would have on workers' performance
(C) for investigating what the effects on workers' performance are that changes in working conditions would cause
(D) that investigated changes in working conditions' effects on workers' performance
(E) to investigate what the effects changes in working conditions would have on workers' performance

FIRST of all you must think who plays strong role on subsequent verb following " THAT" in this example just read as
AN intensive investigating changes in woring conditions or effects change in working conditions. which one is better? definitely first one is better

same principle goes to you concern that: one tells individual genes bo............ OR substances tell individual genes bo..............SURELY the second one is better
have got the point i wanted to share ?

One of the substances that tell --> "that" tends to modify the nearest most noun which in this case is "Substances".
Substances is plural hence the verb which is directly following the relative clause should be plural.
(I used the word Relative clause because the same structure is also true for "Who")

One of the substances tells --> there is no that hence the Subject here is One and not substances for the verb tells since One is singular it should take singular verb which is "tells".

(C) tells individual genes both when to become active or remain
(D) tells individual genes both when to become active or when to remain

THAT in the original sentence modifies the antecedent ONE, not the SUBSTANCES, so we can eliminate choice (A), (B) and (E). Between choice (C) and (D), choice (D) is better because choice (C) makes an ambiguous meaning whether the verb REMAIN is paralleled with ACTIVE or BECOME. In this case, we can easily discover that REMAIN will parallel with BECOME, not ACTIVE. So, we need the parallel term WHEN TO.

Future tense "will tell" is incorrect here since we are talking about a phenomenon and that requires a simple present. The phenomenon is true even today and will not happen in the future. E out.

Subject here is "substances", which requires the plural "tell". C and D out.

B, C and D are out because the idiom is "both X and Y". Additionally, B doesnt maintain parallelism.

A uses "tell". Uses "both X and Y". "when to become active" || "when to remain quiescent"

A,D,E eliminated since we require 'tell' for substances and out of A and B, B is out as it makes no sense.

the demonstrative pronoun that refers to substances and thus the verb must be plural. thus C & D are eliminated.
the correct idiom is both X and Y. In B, this idiom is not used correctly. hence this answer choice is eliminated.
in E - the entities from the structure both X and Y are not parallel.
tell an individual gene - changes meaning.

you are partly wrong, "that" is the demonstrative pronoun, its antecedent is substances

biologists found one of the substances

these substances tell smth

since that refers to substances, the plural verb tell is needed.

it would be correct if "that" was not present here.

one of the substances tells - ok
but this is not the case

This question is troubling and if someone can explain to me clearer, I will much appreciate it.

The idea of "that" baffles me because
1) I understand that GMAT uses "that" to modify the preceding noun "substances". However, the meaning does not make sense to me because it is not all the substances that "tell(s)" the gene when to become active or not, but that "one" substance. That is the meaning of the sentence to me. If we are applying GMAT's rule strictly though, I guess we have no problems.
2) But, as in this link http://gmatclub.com/forum/horses-have-a-unique-system-of-interlocking-ligaments-and-bones-192969.html, i can say sufficiently that the "that" can modify the "XX of YY and ZZ" if it sufficiently makes sense for the meaning of the statement.
3) This means that there should not be any hard rule or there are exceptions to this rule, especially if it makes sense. So if, say the exceptions, liken that of "XX of YY, which" when "which" modifies XX, doesn't it also mean that our question here, with "that", should modify "one" and give our answer "tells"?

Hi,
1) "that" in "One of the substances that" correctly refers back to substances..
The meaning is also correct..
It does not mean that all substances tell the gene..., It is rather putting retriction on the substances..
We are now talking of ONLY those substances that tell the gene..... AND scientists have found ONE of them...
2) Yes which and that can refer to some slightly faraway noun at times. In these conditions generally there is no verb in between and there is no ambiguity.
