Industrial engineer: Some people have suggested that the problem of global warming should be addressed by pumping some of the carbon dioxide produced by the burning of fossil fuels into the deep ocean.Many environmentalists worry that this strategy would simply exchange one form of pollution for an equally destructive form. This worry is unfounded, however; much of the carbon dioxide now released into the atmosphere eventually ends up in the ocean anyway, where it does not cause environmental disturbances as destructive as global warming.

Which one of the following most accurately expresses the conclusion of the industrial engineer’s argument as a whole?

(A) Global warming from the emission of carbon dioxide into the atmosphere could be reduced by pumping some of that carbon dioxide into the deep ocean.
(B) Environmentalists worry that the strategy of pumping carbon dioxide into the deep ocean to reduce global warming would simply exchange one form of pollution for another, equally destructive one.
(C) Worrying that pumping carbon dioxide into the deep ocean to reduce global warming would simply exchange one form of pollution for another, equally destructive, form is unfounded.
(D) Much of the carbon dioxide now released into the atmosphere ends up in the ocean where it does not cause environmental disturbances as destructive as global warming.
(E) To reduce global warming, the strategy of pumping into the deep ocean

Akela -Option E seems to be incomplete. Please write the complete option E.

Although seems E option is not completely written


I would go with C.


Engineer's argument is trying to disprove worry of environmentlists .


C correctly describe this .


award kudos if helpful..

But C only rewrites the consideration again, without offering any conclusive stance. It says worrying.... is unfounded. And this statement made in the stem already.

Therefore I feel E could be better.

Do you agree with the OA? Could you explain the other choices as well?

The confusion is clearly between C and E. But E can be discredited because the use of CO2 into seas is not his opinion. As stated in the begining of the stimuli, "Some people have suggested..." The author's conclusion is only the last statement that it need not be that destructive afterall, which is rightly paraphrased in option C

AndrewN in questions such as this, where we have to select the right conclusion, and where the conclusion in the stem is already mentioned, do we have to look for a paraphrase? Or a more subtle and all-encompassing statement? Thank you in advance!

This is probably the right explanation. In fact, contesting against the ‘worry’ seems the focus for the Industrial Engineer and not wether we should go ahead with process. Hence C is better than E.

Hello, Shikhar22. I am going to try something a little different in the way of analysis this time, using a color-coded image that I have prepared as a prop. To answer your query, you want to tackle this question or any other that asks about the conclusion of an argument the same way: Stick to exactly what the conclusion says. If you do, you cannot go wrong. All you have to do is identify that conclusion. How about we have a look?

The passage map is simple. The first two lines tell us what other people, not the industrial engineer, think about an issue. I boxed just the beginning of those lines because the frame is all that matters. Believe it or not, we do not care about the details of what others believe or worry about. The question asks about the conclusion of the industrial engineer, so until the engineer might offer an opinion on these views, we can more or less ignore them. The next line, however, does just that. Note the strong, judgmental language: This worry is unfounded, however. That is the engineer talking. What follows the semicolon provides the rationale behind that conclusion, not the conclusion itself. All we need to do now is play a matching game with the answer choices.

(A) and (E), the most popular incorrect answers, fail for the same reason. The engineer is not interested in offering suggestions to fix global warming. That has nothing to do with the conclusion, which merely criticizes a view. Just because someone offers a contrary opinion, you cannot assume that a counterproposal is in place.

(B) restates one of the views from earlier in the passage, but that does not make it a conclusion. In fact, if I tell you that someone has concluded something, you can only consider that information a statement, one about the conclusion of someone else. Again, the frame, how information is presented, is what counts.

(D) fails because it restates the justification for the conclusion. In another type of CR question, this information would fill in the blank: This worry is unfounded, however, since ________________.

The key to breaking down the question, then, lies in sticking to the fundamentals: identifying background information, premises, and a conclusion. I hope that helps. I had a lot of fun with the question and doctoring up an image to outline my thought process. Let me know what you think.

Thank you for bringing the question to my attention, and as always, good luck with your studies.

- Andrew

Thank you so much for the work you put in for the explanation! I greatly appreciate it. I understand the conclusion so much better now. And most importantly why the other deceptive choices are wrong! Loved the colour graphic! Makes it much easier to understand 👏🏻
