Industrial and automobile pollution have long been thought to contribute to global warming. However, researchers have identified that the carbon dioxide and carbon monoxide released into the atmosphere are not as potent as the methane emitted by cud-chewing animals such as cows when they fart or belch. Therefore, if you drive a hybrid electric car to the grocery, any favor that you would do to the environment would be offset if you end up buying beef.

Which of the following best describes the author's reasoning?

A. The author establishes a point by drawing an analogy

B. The author disproves a popular notion by providing evidence that is contrary to it

C. The author presents a new theory in response to an existing well-established theory

D. The author uses an illustration to support a new school of thought that is contrary to a popular school of thought

E. The author makes a comparison between two theories by providing an example

Pre-thinking :
The author mentions different factors responsible for global warming, and renounces the existing belief that industrial and automobile pollution are the main factors responsible for global warming. Instead, the author states another theory that cattle belching(beef consumption contributes to global warming) has a greater impact compared to the former.

A. The author establishes a point by drawing an analogy --> No such analogy is made
B. The author disproves a popular notion by providing evidence that is contrary to it --> No evidence is provided
C. The author presents a new theory in response to an existing well-established theory --> It is not a new theory, researchers have identified it before
D. The author uses an illustration to support a new school of thought that is contrary to a popular school of thought --> Correct, matches our pre-thinking
E. The author makes a comparison between two theories by providing an example --> No comparison is made

Hence, D.

I find little difficult to agree with reasoning that it is not a new theory.


D. The author uses an illustration to support a new school of thought that is contrary to a popular school of thought


C and D close choices.

Researchers have identified.....

[color=#ff00ff]not before

So something which researcher have identified can be called new theory...

Just my views....

Harshgmat

But why are you much concerned about second party i.e Researcher's finding and not about author's.
I mean, are we not looking for an answer from the authors point of view(most of the times in CR) ?

Although both C and D are the only contenders, its just that option D matches the reasoning of the stimulus more than the former.

For an instance,
You are aware of Donald Trump's ideologies,which are new, and you equally support those ideologies. You made a reference to his ideologies in your speech.
But the particular ideologies you have used in your speech are not New/Orginal, its someone else's ideologies(new) that you have used to support your claim.

Drops mic ! :thumbup:
