Dear Friends,

Here is a detailed explanation to this question-
skim
In virtually all types of tissue in every animal species, dioxin induces the production of enzymes that are the organism’s trying to metabolize, or render harmless, the chemical that is irritating it.


(A) trying to metabolize, or render harmless, the chemical that is irritating it

(B) trying that it metabolize, or render harmless, the chemical irritant

(C) attempt to try to metabolize, or render harmless, such a chemical irritant

(D) attempt to try and metabolize, or render harmless, the chemical irritating it

(E) attempt to metabolize, or render harmless, the chemical irritant


Meaning is crucial to solving this problem:
Understanding the intended meaning is key to solving this question; the intended core meaning of this sentence is that dioxin induces the production of those enzymes that are the organism’s attempt to metabolize the chemical irritant.

Concepts tested here: Meaning + Pronouns + Idioms + Awkwardness/Redundancy

• “to try to” is a correct idiomatic usage.
• "attempt + to" is the correct idiomatic construction

A: The sentence formed by this answer choice alters the meaning of the sentence through the phrase "organism’s trying"; the construction of this phrase produces an incoherent meaning; the intended meaning is that dioxin induces the production of those enzymes that are the organism’s attempt to metabolize the chemical irritant. Further, Option A uses the needlessly wordy phrase "the chemical that is irritating it", leading to awkwardness and redundancy.

B: The sentence formed by this answer choice alters the meaning of the sentence through the phrase "organism’s trying"; the construction of this phrase produces an incoherent meaning; the intended meaning is that dioxin induces the production of those enzymes that are the organism’s attempt to metabolize the chemical irritant.

C: This answer choice suffers from pronoun error, as the pronoun phrase "such a chemical irritant" lacks a clear and logical referent. Further, Option C redundantly uses "attempt to" alongside "try to", rendering it awkward and needlessly wordy.

D: This answer choice incorrectly uses the unidiomatic construction “to try and” rather than the idiomatic construction “to try to”; please remember, “to try to” is a correct idiomatic usage. Further, Option D uses the needlessly wordy phrases "attempt to try" and "the chemical irritating it", leading to awkwardness and redundancy.

E: Correct. The sentence formed by this answer choice uses the phrase "organism's attempt", conveying the intended meaning - that dioxin induces the production of those enzymes that are the organism’s attempt to metabolize the chemical irritant. Further, Option E avoids the pronoun error seen in Option C, as it uses no pronouns. Additionally, Option E correctly uses the idiomatic construction "attempt to", avoiding the idiom error seen in Option D; remember, "attempt + to" is the correct idiomatic construction. Besides, Option E is free of any awkwardness or redundancy.

Hence, E is the best answer choice.

All the best!

In virtually all types of tissue in every animal species dioxin induces the production of enzymes that are the organism’s trying to metabolize, or render harmless, the chemical that is irritating it.
(A) trying to metabolize, or render harmless, the chemical that is irritating it.
(B) trying that it metabolize, or render harmless, the chemical irritant
(C) attempt to try to metabolize, or render harmless, such a chemical irritant
(D) attempt to try and metabolize, or render harmless, the chemical irritating it
(E) attempt to metabolize, or render harmless, the chemical irritant

So first of all it does not sound good :). If it were like

"enzymes are trying...." or like then it would have need our consideration. SO A, B are wrong and we have to use attempt.

(C) attempt to try to metabolize, or render harmless, such a chemical irritant (Wordy as attempt to try to...its like saying repeating again :) )
(D) attempt to try and metabolize, or render harmless, the chemical irritating it (Wordy)
(E) attempt to metabolize, or render harmless, the chemical irritant

E is clear winner and it has to be the OA.

Hi thangvietnam,

Adopting in answer choice (C) is correct.

In the question you mentioned correct answer is (C)

Option (B) has meaning error-- As per the sentence the imposition is on

1) Truck
2) Bus Engine's polution


Actually the imposition is on pollution by engines of both truck and bus, making (B) incorrect

Both of the modified options below are correct

(B) to impose new controls on pollution from truck and bus engines by the joint adoption of
(C) to impose new controls on pollution from truck and bus engines by jointly adopting


joint adoption and jointly adopting -- both are correct;

Hope it helps.

(D) attempt to try and metabolize, or render harmless, the chemical irritating it
(E) attempt to metabolize, or render harmless, the chemical irritant

Hi Experts,


the phrase "that are organism's...." is modifying "enzymes" or clause "dioxin induces the production of enzymes"?
as "that" is followed by "are" hence it should be "enzymes" but analysis of meaning suggests that it should be "dioxin induces the production of enzymes".

Please help. Where is my analysis going wrong.

Hi there,

You are correct in saying that the plural verb "are" indicates that "that" refers to enzymes. The meaning is that dioxin induces something: what does it induce? It induces the production of enzymes. These enzymes are the organism's attempt to metabolize the chemical or render it harmless. I agree that it would be more logical to infer that the production of the enzymes should be the entity being modified, but from the intended meaning of the sentence, it is clear that "that are" refers to enzymes since this part is not underlined.

I hope this helps!

Regards,
Meghna

(A) trying to metabolize, or render harmless, the chemical that is irritating it.
(B) trying that it metabolize, or render harmless, the chemical irritant
(C) attempt to try to metabolize, or render harmless, such a chemical irritant
(D) attempt to try and metabolize, or render harmless, the chemical irritating it
(E) attempt to metabolize, or render harmless, the chemical irritant

ANS - OA is E .

Lets eliminate incorrect option .

A. organism’s trying to metabolize, or render harmless, the chemical that is irritating it.
Possesive + participle is always wrong .
It is a strict NO NO. Never choose a choice that has this formation. For example, "organism’s trying" is wrong .

B. organism’s trying that it metabolize, or render harmless, the chemical irritant .
Possesive + participle is always wrong .
It is a strict NO NO. Never choose a choice that has this formation. For example, "organism’s trying" is wrong .
" Trying " will always take "to"
this answer has 2 mistakes .

C. organism’s attempt to try to metabolize, or render harmless, such a chemical irritant .
It is redundant and awkward . either it should be attempt to metabolize or try to metabolize.
both "try and attempt " at a same time redunt .

D. organism’s attempt to try and metabolize, or render harmless, the chemical irritating it .
Incorrect idomatic . To try and metabolize is wrong . to try to is right .

E. organism’s attempt to metabolize, or render harmless, the chemical irritant .
Correct .

I was stuck between D and E. Picked D :(
Could you explain the issues in D? As in, which part is redundant?

'Attempt' and 'to try' mean the same thing hence, redundant.

VeritasKarishma MentorTutoring Abhi077 AjiteshArun

Can you confirm sentence structure and parallel list here:
In virtually all types of tissue in every animal species, (opening modifer that modifies dioxin)
dioxin induces the production of enzymes (independent clause -1)
that
are the organism’s trying to
  • attempt to metabolize,
  • or render harmless,
  • the chemical irritant

I can not understand how attempt to metabolize (infinitive form of verb) , render harmless (verb) is
||el to chemical irritant (a noun)? Is the list functions performed by enzymes or organisms?

Furthermore, if OR is a ||el marker. why we do not have OR before RENDER in (E)?

Hello, adkikani. Thank you for tagging me. This or phrase is a non-essential part of the sentence that is interrupting the embedded clause, namely that are the organism's attempt to metabolize the chemical irritant. It is acting to describe the process in different terms, nothing more. Notice that you could just as easily create an embedded clause that ran, that are the organism's attempt to render harmless the chemical irritant. The double commas in the answer choice indicate that the or phrase is simply redefining or describing the same process that was mentioned just before. Hence, the two verbs are parallel to each other and no noun. As for your question about what is performing the functions, it is the organism that is trying to render harmless a chemical irritant. How does it do this? It, the organism, produces enzymes through a dioxin pathway in its tissues.

I hope that helps. If you have further questions, feel free to ask.

https://www.nytimes.com/1983/01/23/us/dioxin-s-peril-to-humans-proof-is-elusive.html

In virtually all types of tissue in every animal species tested, Dr. Poland of the University of Wisconsin's laboratory said in an interview, TCDD induces the production of enzymes that are the organism's attempt to metabolize, or render harmless, the chemical irritant.


The basic structure of the sentence is this:

... dioxin induces the production of enzymes (that clause modifying enzymes).
that clause - that (enzymes) are the organism’s attempt to metabolize, or render harmless, the chemical irritant.

Since we have organism's before the start of the underlined part, we are looking for a noun right after it. Hence, we use attempt.
If we use 'attempt', we don't need to use 'try'. Attempt already means try.

Further, the parallel elements are: attempt to metabolize, or render harmless the chemical irritant
So these two are in parallel:
- attempt to metabolise the chemical irritant
- attempt to render harmless the chemical irritant

Answer (E)

Hi adkikani,

We can read the sentence that option E leads to like this:
...dioxin induces the production of enzymes that are the organism’s attempt to metabolize, or render harmless, the chemical irritant.

I don't know anything about dioxins (or enzymes, or metabolism... :)), but I read that or as introducing another option. That is, it is not the same thing, but an alternative. The enzymes are an attempt to (a) metabolize or (b) render harmless {something}.

The use of participles with possessive nouns end up as awkward sentences.

In the options, we see that ‘attempt to’ makes better sense when used with the possessive organism’s.

Eliminate Options A and B.

The use of ‘attempt to try’ although informal/colloquial is redundant.
We need only ‘attempt’ here.

Eliminate Options C and D.

Option E is the best choice.

Hope this helps!

A) Trying is wrong : -ing here working as noun, which is not desirable
B) Same as A
C) Attempt and Try means same thing, thus redundancy
D) Same as C. Also we cannot use pronoun "it" for possesive noun
E) Correct

I respect what you have to say, end of story--but I do take issue with unsubstantiated opinions when they come from Experts, since such opinions can lead readers astray.
Hi AndrewN,

I respect your opinion as well, and I thank you for removing the word “dangerous” (to describe my opinions) from your reply, which was uncalled for. I don't think that people looking to take the GMAT need to worry about the point we're discussing, but to be very clear: I maintain my position that there is no one way to read that phrase without using outside knowledge.

For anyone else who may have found this (experts taking opposite positions) confusing:
1. Generally speaking, with a few exceptions, the usage of commas is not something governed by very strong rules. Most such “rules” are in fact guidelines, and there is plenty of disagreement over how commas can, or should, be used.

2. I don’t believe that an or within a pair of commas can be used in only one way. To assert that there is only one way to use “, or… ,” in the English language is, to me, absurd.

3. Normally, the opinion that matters the most is the GMAT’s, but we just don’t see the GMAT asking us to take decisions on the basis of anything this nuanced. Apart from a few issues (like comma splices), test takers should be able to ignore overly prescriptive advice about commas.

An odd time to return to this old post, AjiteshArun. From what I can tell, I have not edited my earlier posts, but regardless, I would like to publicly apologize for prompting such a response nine months after the fact. To be clear, I agree with all three points you have listed above; in fact, speaking to the second, I cited more than one way to interpret the or within commas and opened the door to other possibilities. Ever since writing that post, however, I have thought that I could have aimed to make a point with a bit more tact.

I hope all is well on your end, and I look forward to reading more of your posts in the forum.

If that apology is aimed at me as well, it is not necessary. I meant it when I thanked you for removing something that I felt was close to a personal attack, something more than simple disagreement. And again, I have nothing against your continuing to hold to the view that a pair of commas around an or can somehow prevent it from playing its primary role of introducing alternatives.

An odd time to return to this old post, AjiteshArun. From what I can tell, I have not edited my earlier posts, but regardless, I would like to publicly apologize for prompting such a response nine months after the fact.
Funnily enough, it was your own PM a while back asking me whether I was offended by anything in your post that prompted me to finally look up the GMAT club email with the original response, before any edits. That said, the point is moot, as that part of your reply is no longer there.
