Although there has been great scientific debate for decades over global warming, most scientists now agree that human activity is causing the Earth’s temperature to rise. Though predictions vary, many global warming experts believe that average global temperatures will rise between three and eight degrees Fahrenheit during the next century. Such an increase would cause an alarming rise in sea levels, displacing millions of people by destroying major population centers along the world’s coastlines.

Which of the following is an assumption in support of the argument’s conclusion?

A. New technological developments in the next century will not divert rising seas from the world’s coastal cities.
B. Individuals will not become more aware of the steps they can take to reduce the emission of greenhouse gases.
C. Rising sea levels similarly affect all coastal population centers.
D. Some global warming experts predict a greater than eight degree Fahrenheit increase in global temperatures during the next century.
E. Human activity is the sole cause of increasing global temperatures.

Which of the following is an assumption in support of the argument’s conclusion?

A. New technological developments in the next century will not divert rising seas from the world’s coastal cities.--- I think this is the assumption on which conclusion ( i.e the coastlines cities will be destroyed due to global warming), so now we are assuming that tech development will not help in diverting seas from the coastal cities, even if the temp rises

B. Individuals will not become more aware of the steps they can take to reduce the emission of greenhouse gases. -- PAssage never mentions anything about tge green house gases

C. Rising sea levels similarly affect all coastal population centers. -- It doesnt matters whether it affects similarly or not, the cities will still be destroyed.

D. Some global warming experts predict a greater than eight degree Fahrenheit increase in global temperatures during the next century. -- Ok, but how does that matters, cities will be destroyed due to rising sea levels

E. Human activity is the sole cause of increasing global temperatures.-- Even if human activities are not teh sole cause, then also cities will be destroyed but this time may be due to some other reason

Whats the OA ?

Edited the post for OA

You are correct

The argument concludes that rising sea levels caused by global warming will destroy major coastal population centers and displace millions of people. Any assumption in support of this conclusion would have to corroborate that these events will definitively take place.

I thought that A is out of scope. In assumption questions we should use just given info, isn't it?

Yes, you should only use information given in the passage. But, the assumption given in the answer choice is the information additional to what has already been given in the passage. And you have to use this external information as an assumption to draw the conclusion.

I also made the mistake in this question. I chose B in the first place. It cannot be B since it does not say in the passage that Green House Gases are the main contributors to the temperature rise. I used external information and the answer I got was wrong.

Between A and E , but the word 'Sole' in E doesn't sounds good.
would go with A

Conclusion: People in coastal areas will have to relocate as the coastal cities will submerge into sea-water because of its rising level due to high temperatures.

New technological developments in the next century will not divert rising seas from the world’s coastal cities.
The temperatures will rise. And even the technology will not be able to protect the coastal cities from drowning. Thus, beware all living in Miami, you guys will have to relocate to Adirondacks in a century or so.

Individuals will not become more aware of the steps they can take to reduce the emission of greenhouse gases.
Greenhouse gases- what does this do? Does it affect the environment. Does it make the weather colder? Out of scope.

Rising sea levels similarly affect all coastal population centers.
Extra information. No use to me.

Some global warming experts predict a greater than eight degree Fahrenheit increase in global temperatures during the next century.
It can surely prove the gravity to which the conclusion holds true. Also, we already know this by inference of the phrase "Though predictions vary" and it is not an assumption. And it doesn't support the conclusion.

Human activity is the sole cause of increasing global temperatures.
Thanks for blaming humans. But, how does it effect/support the conclusion.

Ans: "A"

Negating A clearly crashes the conclusion about problems encountered at the coastal areas.

A it is.

I think (A) is correct.

Because conclusion is rise in temperature > rise in sea level > destroy coastal line cities. If A is not an assumption and if negated, it means new technology can save the coastal line cities in the next century.

This sentence I saw A is the assumption, but it is not strong enough comparably with other questions.

I also confuse with B, but after negate. In (B), when negate, meaning that the awareness of people did not make the consequence become less serious.

Hey,

Option B is out of scope. Here they don't talk about the emission of green house gases.

Nope. I don't think B out of scope. In assumption, we should not consider answer choice out of scope. Do you feel A relate to the emission of oil? No, it is not related but it is the NECESSARY info.

I think the argument revolves around the effect of global warming. It talks more about the impact of global warming and the consequences. So we must restrict our scope within that frame.
