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.

Dear Prashant10692,

I'm happy to respond. :-)

My friend, I'm sorry to say that you misapplied this cheap trick. You misinterpreted the interpretation of the clause at the end.

The clause at the end is intended to be an appositive for the final word preceding it, "reason." If we wanted to specify a reason, this is a poor way to do it. A colon would have been better than a comma to indicate that the reason was being given.

Choice (D) has a large number of problems. The wording is awkward in a variety of ways. You are looking at individual grammar rules and you are missing the forest for the trees. My friend, it's so important to develop your intuition for English by developing a habit of reading. The rule-based approached to GMAT SC is a conveyor belt to the middle of nowhere.

Does all this make sense?
Mike :-)

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 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

(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

(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

(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

AjiteshArun ,GMATNinja ,mikemcgarry , egmat ,sayantanc2k , other experts -
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 ?

Dear Skywalker18

I'm happy to contribute to this discussion. :-)

I see that my intelligent colleagues AjiteshArun and sayantanc2k have already responded. With all due respect to those gentlemen, I would give a slightly different reply.

Because "if" is a subordinate conjunction, this word always begins a full clause that requires a full verb. I believe the GMAT would say that "if used repeatedly" is correct only because it is understood that a simple [pronoun] + [auxiliary verb] pair has been omitted.

If [they are] used repeatedly in the same place, certain pesticides can become ineffective.

Here, we see that the verb is NOT a past tense verb at all. Instead, it's a present-tense passive verb.

Does all this make sense?
Mike :-)

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!
