HENCE  C

TirthankarP · Answer

I agree that option C is the best. But I think the pronoun "they" in option C is ambiguous. It can refer to both "portugese explorers" and "peanuts".

PRONOUN AMBIGUITY IS NOT THE ABSOLUTE RULE.

abhijeetjha · Answer

Gmat sentence corrections now a days is all about meaning and grammar...in the option C as it says if we replace this option with the underlined portion of the original sentence it reads "Native to south america ,  peanuts  were introduced to Africa by Portugese explorers early in the sixteenth century and were quickly adopted into Africa's agriculture, probably because  they  were so similar to the Bambarra groundnut, a popular indigenous plant.

Now the" they "here has been compared with Bambara groundnut in the non underlined portion of the sentence..Can we say that they stands for Portugese explorers and then the Portugese explorers are compared with Bambarra groundnut ?? Isnt it absurd and nonsensical?? So "they" can only refer to the peanuts to preserve the sensical meaning of the sentence ..

EducationAisle · Answer

One needs to take a holistic view of the answer choices. A, C, D and E all use "they"; B is not even a sentence. That being the case, it should be apparent that pronoun ambiguity is not being tested in this sentence.

The reason this kind of an approach is important, is because one should not adopt a "puritan's view" of options; quickly summarize things that "matter" in the answer choices and then focus on those things. In this case, it should be evident that "they" does not matter.

same as D.

Senthil1981 · Answer

C is correct when compared with other choices, but 
"probably because they  were  ", i'm concerned with "were", should not it be "are" , since they are still similar ?
It's like "my blood group was O+"

Anyone wanna clarify this ?

rcaraujo20 · Answer

Hello,

As indicated, in letter B clauses are not complete parallel ('verb + object' X 'adverb + verb + object'), but I am not sure about verb tense parallelism: since both clauses are in past tenses (past perfect and simple past), are they parallel in terms of verb tense?

In other words, if I correct the parallelism and other errors, but maintain verb tenses, it would be correct? For example:
 '...peanuts having been introduced to Africa by Portuguese explorers  since 1600  and  were  adopted into Africa’s agriculture  by natives in 1650 , probably because  they were ...'

Could anyone clarify?

(On the other side, (1) as already pointed out before, the fragment 'probably because of being' has no main verb; (2) one cannot use past perfect if time is defined: 'having been introduced...' and  'early in the sixteenth century' )

Best,

fmanan · Answer

No PN ambiguity issue b/c 'they' is parallel to peanuts (subject-subject in both clauses)

Answer C

HimanshuW11 · Answer

Dear  TirthankarP ,

I resonate with  fmanan  here, as "They" in option C clearly refers to peanuts and not to Portuguese explorers.
As these are two different clauses in the same sentence, and they being the first pronoun in the second clause "probably because they were.....indigenous plants" refer to the first noun in the preceding clause i.e. the first clause "peanuts were introduced .....Africa's agriculture".
For more clarity on the pronoun ambiguity Kindly refer to the video lesson by  GMATNinja   https://www.youtube.com/watch?v=IhN_KU1bSKU

a.when peanuts were introduced to Africa by Portugese explorers early in sixteenth century they were quickly adopted into Africa's agriculture, probably because of being

b.peanuts having been introduced to Africa by Portugese explorers early in the sixteenth century and quickly adopted into Africa's agriculture,probably because of being

e.peanuts,introduced to Africa by Portugese explorers early in the sixteenth century and having been quickly adopted into Africa's agriculture,probably because they were

First thing, A and B are gone for using 'because of being', as a modifier. Second, if one is aware of the basic structure of a sentence, which is the most basic to SC, one can within seconds make out D and E are fragments.

That leaves us with just C in less than half a minute. The so-called ambiguity of the pronoun 'they', is merely tentative rather than logical.

Honestly, is there anything more to this question?

MHIKER · Answer

Isn't in option C the pronoun "they" improperly referring to explorers?

saurabh9gupta · Answer

I rejected all except C because other options have a missing verb issue

daagh · Answer

What is the logic behind saying that the pronoun 'they' refers to explorers who were similar to a local groundnut plant? Were the explorers human beings or not?

It also means that if there was one pronoun like 'they', we cannot have more than one plural noun in a sentence.

apovit · Answer

Hello all,
(A) has a clear modifier error- when is used to show time reference. A is out.
(B) having been introduced shows the previous of a series of events, but there is none.
 because should be followed by a clause (presenting a reason) not with a prepo phrase.
(C) peanuts were introdced and were quickly adopted because they were ---- the error has been corrected.
(D)peanuts has no verb as everything mentioned has been transformed into a modifier.
(E) peanuts has no verb also having been quickly adopted shows a series of events which is not there.

Thanks.
