Use ‘native of’ for human beings only; for all others use ‘native to’; ‘native in’ is wrong; nativity is a universal factor; hence use present tense and A is the answer.

Native of is used for human beings
Native to is used for animals, plants, insects etc..

A person is a native of South America, but I'd say that a species is native to South America.

I felt that A was wrong initially because of the usage of "introduced into Florida" but when compared with the other options A is still the best answer.

(B) 'as attempts to control' -> not correct idiom
(C) 'in an attempt at controlling' -> wrong idiom
(D) 'as an attempt at controlling' -> incorrect idiom
(E) perfect tense not required

A is best.

(A) are native to South America but were introduced into Florida during the 1930’s in an attempt to control
(B) are native in South America but were introduced into Florida during the 1930’s as attempts to control
(C) are natives of South America but were introduced into Florida during the 1930’s in an attempt at controlling
(D) had been native to South America but were introduced to Florida during the 1930’s as an attempt at controlling
(E) had been natives of South America but were introduced to Florida during the 1930’s as attempts at controlling

This is how I thought
D, E - Eliminate - Changes the context - Sentence seems to say that the toads are no longer natives

Left with A, B & C
B - Eliminate - Use of "native in" is wrong.

Left with A & C
C - Eliminate - Use of "in an attempt at controlling" is not a good construction when compared to A

Hence A should be the answer.

The frog is native to a certain country. BCE are wrong. D implies the frog is no longer indigenous to its native country, which is nonsensical.
Therefore A.

Is tense consistency not required? I would like to know if a single sentence can contain both past and present tenses. Any explanation is greatly appreciated as I have been looking around for this answer for a while.

look at it another way...look at d last part
E-- attempts at controlling --wrong idiom
D--again 'attempt at' is wrong idiom
C--it also say d same-' attempt at' again wrong idiom
B-- it say 'attempts to' can consider once but den look at d first part it says 'native in' so eliminate it.cuz no one wud select 'native in' its a common sense
only A remains..moreover A also uses correct idiom in d last part- 'attempt to'

eg. You attempt to do something
Wrong- you attempt at doing something.

Here is my view :

X is native to Y

where X= Animal or species , Y = place or geographical region


X is Native of Y

Where X = Person/ people , Y = place or geographical region

The correct idiom is 'native to.' Even though the subject 'toads' is plural, we still use the singular 'native.' 'Natives to' is unidiomatic. Eliminate (B, (C) and (E).

Another issue going on is the 'had been native/s' vs 'are native/s' split. 'Had been native' suggests that at some future point in time the toads will no longer be native to South America. However, a species can only be native to one place, and their status as such can never change. Therefore, you can get rid of (D).

Since this second point is a little more subtle, you may want to focus on the idiom: Attempt to VERB. That way you can immediately eliminate (C), (D), and (E).

That leaves us with (A).
_________________

Choice A is best. The phrasing are native to correctly suggests that the toad species in indigenous to, and still exists in, South America.

In B, native in is unidiomatic; in C and E, natives of illogically suggests that each toad now in Florida hails from South America.

In D and E, had been inaccurately implies that the toads are no longer native, or indigenous, to South America, and introduced to Florida is unidiomatic. Both as attempts in B and E and as an attempt in D are wrong because the attempt consists not of the toads themselves, but of their introduction into the environment.

The correct phrase, in an attempt, should be completed by an infinitive (here, to control), as in A.

Answer: A.
_________________

Choice A is indeed the answer.
'native to' and 'in an attempt to' are correct usages

Choice A : This choice uses idiomatic expressions 'native to' and 'in an attempt to'. Simple Present tense in 'Toads are native to' is correct to express the fact.
Choice B : 'native in' and 'as attempts to' are incorrect.
Choice C : 'natives of' is accepted when referred to People and not when referred to Animals.
Choice D : Usage of 'had been' is illogical. It suggests that toads are no more native to South America, which is nonsensical.
Choice E : Incorrect for the reasons cited in Choice D and C
_________________

"In an attempt to control" ---- > This sounds best to my ears than the other options...
Even if one does not read the initial part before those last 4 5 word in each options it is OK... that is just my opinion.
"A" for me.

A native of refers to humans

A native to refers to non human things ( category, characteristic, or species etc...)


Correct answer will hence be (A)
_________________

A correct

B incorrect

are natives in ..... incorrect idiom
C incorrect

are natives of....
attempt at controlling.....
incorrect idiom

D and E ....
wrong tense used...
A specie is always a native to something....

Hi Experts is this right?
Can this be used as a rule in GMAT?

Thanks in advance

1st split native to/native of = for animals = B,C,E - out
2nd split are/had been - the tense should be are because no consiquentce = D - out

Answer A

Hi
egmat GMATNinja VeritasKarishma ChiranjeevSingh

In option D & E.
1.meaning is distorted by telling toads are no longer natives.
2.also now there isn't any contrast is it just acting as fact?
