[quote="egmat"]Hi Rahul,

Thank you for posting your doubt here. :-)

Let's break this official sentence in its clauses:

Cl. 1: Certain pesticides can become ineffective if used repeatedly in the same place; (IC)

Cl. 2: one reason is suggested by the finding (IC)

Cl. 3: that there are much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in soils (DC)

Cl. 4: that are free of such chemicals. (DC)

In this sentence, "that" refers to "finding" as its give detail about what that finding is. So yes, "that" refers to "finding".


Hi Shraddha/ E-Gmat,

"Certain pesticides can become ineffective if used repeatedly in the same place; one reason is suggested by the finding that there are much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in soils that are free of such chemicals."

In this sentence, "that" refers to "finding" as its give detail about what that finding is. So yes, "that" refers to "finding".

Now I am bit confused that how that can modify "finding" ,1)Finding is singular subject but the verb used for that is "are" ( since that act as subject here) ,2) logically if I replace that with finding then the clause becomes "finding are free of such chemicals" and 3)how can that jump over a complete clause to modify finding.

Kindly advise me about the above , maybe my understanding of That is completely wrong.

Certain pesticides can become ineffective if used repeatedly in the same place;one reason is suggested by the finding that there are much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in soils that are free of such chemicals.


(A) Certain pesticides can become ineffective if used repeatedly in the same place;one reason is suggested by the finding that there are much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in soils that are free of such chemicals.

(B) If used repeatedly in the same placeone reason that certain pesticides can become ineffective is suggested by the finding that there are much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in soils that are free of such chemicals.

pesticides are used repeatedly not any reason. Modifier error.

(C) If used repeatedly in the same place,one reason certain pesticides can become ineffective is suggested by the finding that much larger populations of pesticide-degrading microbes are found in soils with a relatively long history of pesticide use than those that are free of such chemicals.

pesticides are used repeatedly not any reason. Modifier error. Also this implies that removal of that makes the sentence awkward.

(D) The finding that there are much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in soils that are free of such chemicals is suggestive of one reason, if used repeatedly in the same place, certain pesticides can become ineffective.

Suggestive of is not idiomatic and ambiguous
Also there is no proper conjunction between two clauses. comma does not help us get intended meaning.


(E) The finding of much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in those that are free of such chemicals suggests one reason certain pesticides can become ineffective if used repeatedly in the same place.

finding of microbes does not make sense.
that cannot refer to those and also not refer to soils properly.

Hello mikemcgarry abhimahna

I have a doubt in this one.
The reason I eliminated D is :

The finding that there are much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in soils that are free of such chemicals is suggestive of one reason, if used repeatedly in the same place, certain pesticides can become ineffective.

Using Underlined as a dep clause and fitting it in the start of the sentence. I know pretty cheap trick. :P

For example if used repeatedly in the same place, certain pesticides can become ineffective ,The finding that there are much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in soils that are free of such chemicals is suggestive of one reason.

So here it doesn't even make sense and I crossed it.

Is it worth going with as a strategy?

Thankyou in advance.

In OA-A , can you please enlighten on the usage of the underlined part as below that can be reworded as - If used repeatedly in the same place, Certain pesticides can become ineffective.
Since the If part of the sentence is in simple past (used), shouldn't the then part of the sentence be in simple past or use would verb ?

Hi,

I drilled down to option A and D. I found both the options as awkward, but eliminated D as it is a run on sentence. but for the 'that' in option A, I was little confused.
In another thread you said "“that” is always singular when it’s being used as a pronoun". I actually noted this down to solve questions. But in this option A, 'that' is referring to plural... please suggest.

Excellent question! Here's the distinction: as a conventional pronoun, we use "that" for singular entities and "those" for plural. For example:

    "Tim's phobias of sharks and dolphins are far more severe than those of his two-year-old daughter, who fears only broccoli and sleep."

"Those," in this case, is functioning as a pronoun, or a stand-in for another noun: we're comparing Tim's phobias with his daughter's phobias.

But as a modifier, we always use "that," even when we're modifying a plural noun:

    "The phobias that really crippled Tim mostly involved harmless sea creatures."

Here, "that" is functioning as a modifier describing Tim's phobias, rather than introducing a fresh set of phobias, as we did in the previous example.

The takeaway: we want "those" if we're using a pronoun as stand-in for a plural noun, and we use "that" if we're modifying a plural noun (or if we're modifying any noun).

I hope that helps!

The topic is split with a semicolon, a sensible thing to do in such cases.

(B) If used repeatedly in the same place, one reason that certain pesticides can become ineffective is suggested by the finding that there are much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in soils that are free of such chemicals. -----The participial modifier - If used repeatedly- should modify pesticides and not one reason

(C) If used repeatedly in the same place, one reason certain pesticides can become ineffective is suggested by the finding that much larger populations of pesticide-degrading microbes are found in soils with a relatively long history of pesticide use than those that are free of such chemicals. -----------The participial modifier - If used repeatedly- should modify pesticides and not one reason

(D) The finding that there are much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in soils that are free of such chemicals is suggestive of one reason, if used repeatedly in the same place, certain pesticides can become ineffective.----- The sentence is a run –on. The second part of the topic, going after - if used repeatedly – is dangling loosely without a connector such as that or a semicolon. Hence, wrong

(E) The finding of much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in those that are free of such chemicals suggests one reason certain pesticides can become ineffective if used repeatedly in the same place---- As in D, a connector as –that- is essential between reason and certain.



Hi sir,

Am i correct in eliminating D ????
----> IC, IC is wrong thats why D is a run on.

Also, i did not understand your explanation to eliminate D --- dangling modifier loosely attached. Can you elucidate further ?
