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?

New technological developments in the next century will not divert rising seas from the world’s coastal cities.

Individuals will not become more aware of the steps they can take to reduce the emission of greenhouse gases.

Rising sea levels similarly affect all coastal population centers.

Some global warming experts predict a greater than eight degree Fahrenheit increase in global temperatures during the next century.

Human activity is the sole cause of increasing global temperatures.

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"

+1 to A. A is the only one which supports the argument’s conclusion

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

A it is.
