The ability of scientists to provide models of the atmosphere's complex responses to changing conditions, like seasonal and daily cycles or different planetary conjunctions, have become ever more accurate.

Lets analyze the sentence: this sentence has only one clause
Clause:1 - Ability is subject, have become is verb- Wrong
Use of like to give examples is also wrong.

(A) The ability of scientists to provide models of the atmosphere's complex responses to changing conditions, like seasonal and daily cycles or different planetary conjunctions, have become ever more accurate.

(B) The ability of scientists has become ever more accurate in providing models of the atmosphere's complex responses to changing conditions, such as seasonal and daily cycles or different planetary conjunctions. - Meaning problem - ability become more accurate, Use of in providing is also unidiomatic

(C) Scientists have become able to provide ever more accurate models of the atmosphere's complex responses to such changing conditions as seasonal and daily cycles or different planetary conjunctions. - Correct Choice

(D) Scientists have become ever more accurate in their ability for providing models of the atmosphere's complex responses to changing conditions, like seasonal and daily cycles or different planetary conjunctions. - Shift in meaning and use of like

(E) Scientists' ability to provide models of the atmosphere's complex responses to such changing conditions as seasonal and daily cycles or different planetary conjunctions have become ever more accurate. - Wrong use of have for ability.

I don't know whether what Im doing is correct, but I could get the right answer in no time.
In gmat, Able is preferable to the ability, so A, B and E are out
D has Like + a lot of bla bla not preferable in Gmat
Therefore C is the correct answer. :P
Maybe useful when running out of time :P

A) The ability of scientists to provide models of the atmosphere's complex responses to changing conditions, like seasonal and daily cycles or different planetary conjunctions, have become ever more accurate. Have is wrong , it should be has. Also , it changes meaning of the sentence
(B) The ability of scientists has become ever more accurate in providing models of the atmosphere's complex responses to changing conditions, such as seasonal and daily cycles or different planetary conjunctions. The ability cant be accurate, the scientists have to be
(C) Scientists have become able to provide ever more accurate models of the atmosphere's complex responses to such changing conditions as seasonal and daily cycles or different planetary conjunctions. Correct choice
(D) Scientists have become ever more accurate in their ability for providing models of the atmosphere's complex responses to changing conditions, like seasonal and daily cycles or different planetary conjunctions. in their ability --> able to is a better word structure. Also, 'such as' should be used instead of 'like' to give examples.
(E) Scientists' ability to provide models of the atmosphere's complex responses to such changing conditions as seasonal and daily cycles or different planetary conjunctions have become ever more accurate. Have become more accurate is wrong among other mistakes.

Is 'Ability to' always incorrect?


No, on the contrary, ability to is the correct idiom ..ability of / ability for are wrong.

My ability to sense danger has saved me on numerous occasions... correct.

However can is more concise than have the ability to and hence preferred.

I have the ability to play piano.... wordy
I can play piano...... concise / correct.

The text states clearly that 'the ability of scientists has become ever more accurate’
B maintains this intent intact, while C changes the intent blatantly by saying that ‘Scientists have become able to provide ever more accurate models”

Should we still prefer C over B? Can someone point to a valid grammar error in B, unless he or she wants to insist on a trivial such as ‘in providing’ is not a good idiom or some such.


Hi daagh,
Can ability be more accurate or less accurate? We can say that A has the ability to throw the ball more accurately than B. But we can't say that A has more accurate ability than B. Ability is an abstract idea and accuracy is used for physical things ( I think...)

Therefore they can develop more accurate models but I doubt their ability will become more accurate

In C:
Is the construction "such changing conditions as ... AND ... OR" ok?

It's the "or" that messed me up. I though "Such as" was used either by itself, with AND or with OR, but not with both AND and OR.


Yes, this is correct.

Notice that if we say "conditions such as A or B" OR "such conditions as A or B", both are correct.

We are talking about two conditions here:

1. seasonal and daily cycles , HERE A [IT IS ONE CONDITION --> CYCLE (two types of Cycles are given but condition remains one)]
2. different planetary conjunctions, HERE B.

So, a little meaning understanding is required here before cancelling out the option.

I hope that makes sense. :)
