Isn't they referring to the compound subject "Industrialization and modern methods of insect control" ??

Plus "have improved" needs "have introduced" to parallel ?

Why cant it be C ? "which" is referring to chemical pollutants because "at the same time" seems to be modifying chemical pollutants..

I am not able to decide between B and C :(

What is the OA ?

This is correct: that they refers to "Industrialization and modern methods of insect control".

"Which" in C is wrongly used.
"Having" in A is wrongly used.
Nothing much to say about D and E.

I think "they" is redundant but understood..

So B.

B is correct. I don't know about all of you but I don't go by the rules of grammar at all. In fact, I don't even know more than half the technical things that you all discuss. I am sure when I was in school I read and learnt those things but they have been long forgotten. I simply go by the way I WOULD speak a particular sentence. English is a strange language in a certain sense. What may seem correct in one context may not seem correct in another. The only way to tackle these questions, I think, is to imagine yourself speaking the sentence with your eyes closed and feel if it sounds alright. Now, this may not work for everybody but it does for me.
This particular question, it is my belief, is a perfect example that there are no rules in English (if you know what I mean)!

A. while at the same time they have introduced some 100,000 dangerous chemical pollutants, having
B. while at the same time introducing some 100,000 dangerous chemical pollutants that have
C. while they have introduced some 100,000 dangerous chemical pollutants at the same time, which have
D. but introducing some 100,000 dangerous chemical pollutants at the same time that have
E. but at the same time introducing some 100,000 dangerous chemical pollutants, having

please explain your reasoning..


To me a structure of the sentence has the following logic:

Industrialization and modern methods...have improved the standard of living...while introducing dangerous chemical pollutants...[polutants] have gone unregulated since they (pollutants) were developed...

using 2/3 rule:
While vs. but - While wins. so we can eliminate D&E
In C "which" modifies time
A says that "Industrialization and methods of insects contorol..having gone (sounding awkward at least) unregulated." I think the meaning is distorted.

So B wins.

Going with B on this one.

A & E. Having is very akward.
C. There's no clear referent to they.
D. But introducing - very bad.

Its close between B & D.
I will go with B as 'that' clause in the end modifies pollutants that have gone unregulated.
'that' clause modifies time in D instead of pollutants located in the end of sentence.

I wouldn't be on the 2/3 rule... i find it unreliable. don't eliminate "but" just because it showed up only 2 times. eliminate the answer choices based on other issues in the sentences.

Here's my take on why A is not suitable:
Consider this part: "..while at the same time they have introduced some 100,000 dangerous chemical pollutants, having gone virtually X.."
the problem with the modifier is that it can be taken to refer 'they have introduced'. If you read the stimulus carefully this ambiguity will become evident.
Remember, verb modifiers do not need to touch the verb that they modify.
In B, the modifier clearly refers to the noun chemical pollutant, which it is actually supposed to modify..

Hope this helps.

OK, I agree with that, but...what does your explanation has to do with "while at the same time" being or not redundant?

Between B,C and D that has a clear referrant in B.Hence, B prevails.
