please, help with this one!

IMO A

C and D

"at the same time" modifies pollutants

"And " tries to make an independent clause while we require a subordinate one


D

"that" means only specific pollutants go unregulated. Thats not the case. All pollutants cause this problem

B and E-Incorrect tense.."intoduce" we require present perfect


In B - "that" means only specific pollutants go unregulated. Thats not the case. All pollutants cause this problem


A- correct tense..means methods are still introducing pollutants

"have improved" parallels "have introduced"

IMO C

While at should be while subject verb

The contrast is clear and parallel in C and the "comma" and "and" is required in C to retake the same subject.

Initially I choose A

but when looked at closely, the phrase having gone unregulated....

is a modifying pollutants

Question is whether polutants are unregulated or the methods are unregulated

Hence C looks better option as methods should be unregulated which were introduced 50 years ago.

Dear Jats

" While at the same time " is idiomatic

Hence, I doubt the answer C

In the mean, I felt B to be better of among other and believe it to be the answer


C, D, E eliminated for the reasons mentioned above in my earlier post

A-"they have introduced" is akwward and correctly replaced by "introducing" in B

"That have" is an issue in B and it would be better with participal "having "

( hence I had eliminated B before)

so, I can say its B ( and A is very close but wordy )

According to B,

the "they" in underlined part seems to refer to chemical pollutants but logicall it should refer to methods

OA is B

In B, the v-ing form of the verb is not parallel, but still it is the correct answer

Indeed you r correct.

I read your explanation for eliminating C. Although i agree that "and" is unnecessary and gives the superficious feeling of 2 different actions, but does this has more priority than the one with the bold part above

Eager to see your comments....

Option A " they have introduced " is rightly parallel to the first clause...
no issues on that case.
No way the construction is awkward.

but participle phrase at the end of the should refer to the subject of the preceding clause, which is illogically refering to they ...
hence not correct..

Option B: Solve that problem
and " introducing" rightly refers to an ongoing activity!!!

Between A and B

what went unregulated? Chemical pollutants? as suggested by 'that' in Choice B? or Industrialization and methods of insect control as suggested by choice A?
