if the second part contain do/did, the first part need to have action verb
if the secon part contain helping verb, the first part need to have the same helping verb, maybe in different tense.

Hi AjiteshArun

Could you explain option e in detail?

I hadn’t seen a structure like this until this question..

Best regards!

Hi INSEADIESE,

Option E is a reduced form of
a Clean Air Act that is at least as strong as the present act

The that and the is have been taken out to make the sentence slightly shorter.

The above statement gives clear clues about COMPARISON.
The usage as strong or stronger than is absolutely incorrect for using the idioms only partially.

The correct idioms are:
as...(strong)...as and comparative form of the verb (stronger) + than



Both the above options use the idioms only partially. Even a structure as strong as or stronger than would have been correct but that is missing here.



Another incorrect idiom: so .... as


When this is read with the whole sentence, the structure is weird.
86 percent of the public favored at least as strong a Clean Air Act as is the present act.


This option is pretty smooth, uses correct idiom, and a shorter version of "as strong as or stronger than"

I would choose E.

In a recent poll, 86 percent of the public favored a Clean Air Act as strong or stronger than the present act.


(A) a Clean Air Act as strong or stronger than - does not have the ''as...[adjective]...as" structure.

(B) a Clean Air Act that is stronger, or at least so strong as, - does not have the ''as...[adjective]...as" structure. (instead, B has ''so strong as.'')

(C) at least as strong a Clean Air Act as is - (C) implies that the public favored an event that is comparable to the strength of a clean air act. (C) does not make any sense.

(D) a Clean Air Act as strong or stronger than is - has the same error as described in (A)

(E) a Clean Air Act at least as strong as - has no error. Hence, (E) is the right answer choice.

(A) a Clean Air Act as strong or stronger than
(1) correct idioms are “as strong as…” or “stronger than…”

(B) a Clean Air Act that is stronger, or at least so strong as,
(1) “Or at least so strong as” is an nonessential modifier, so when you remove it you will get something nonsensical – “86 percent of the public favored a Clean Air Act that is stronger the present act.”

(C) at least as strong a Clean Air Act as is
(1) “at least as strong X [Clean Air Act] as is…” should be “X [Clean Air Act] at least as strong as Y [the present act]”

(D) a Clean Air Act as strong or stronger than is
(1) less concise than “at least as strong as”

(E) a Clean Air Act at least as strong as
best option

Hi Experts,

I have a meaning doubt about OE E. We bring a law that is stronger or weaker than the existing law. I am not able to fully understand "at least as strong as". If it is equal to the current law they bring out the new law in the first place.

Hi Arvind, while I agree with your explanation, isn't that the issue with all options?

Yes It is an issue with all options.
I think it better to look out for least wrong option.

More than this, I would like to put it this way:

GMAT test takers need to develop an eye to scan the answer choices and figure out what really matters, to solve this question. Since the issue you have highlighted, exists in all the options, frankly it's a non-issue as far as this question goes, and hence, not worth the effort and energy.
