great scientific debate

by neerajkumar1_1 » Tue Sep 14, 2010 8:36 am
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.
4. Some global warming experts predict a greater than eight degree Fahrenheit increase in global temperatures during the next century.
5. Human activity is the sole cause of increasing global temperatures.

IMO C

The argument is that an increase in global temperature will cause alarming rise in sea levels, which will displace millions of people by destroying major population along the world's coastline. So there is a relation between rise in sea level and population along coast line. C confirmes that. If we use negation method, this argument falls apart.

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.

4. Some global warming experts predict a greater than eight degree Fahrenheit increase in global temperatures during the next century.
5. Human activity is the sole cause of increasing global temperatures.
Conclusion -
an increase would cause an alarming rise in sea levels, displacing millions of people by destroying major population centers along the world's coastlines.
Premises -
1. human activity is causing the Earth's temperature to rise.
2. extrapolates the current trend and forms the belief that average global temperatures will rise between three and eight degrees Fahrenheit during the next century

Assumption is that nothing will be done to reverse the trend ... It will continue
So Option B provides me this...

What is the source of this question ? If I am correct in my response , I would question the source because " greenhouse" gases is a technical term and all people might not be aware... Ofcourse , my argument on the validity of the source depends on my assumption that B is the right answer ..lol

I hope, we do have agreement on the conclusion.
The conclusion is: millions of people along the coastline would be affected because of rising sea level.
Let's negate C.
~C = Rising sea levels WILL NOT similarly affect all coastal population centers.
So what if rising sea level affects major population centres along coastline, but sparing minor population centres.
Still millions of people would be displaced.

Please let me know what you think about this.

After reading through explanation, it is A. I knew that I am looking for "rising seas level" and "coastal cities". Now I know what I did wrong. Good learning. Thanks for this question Neeraj. And thanks "this time I will"

Hi Guyz.
the question is from MGAT...
i suppose the tricky part in the question was to locate the conclusion...
once that was done it was easy...

I got the conclusion wrong... so made a mistake in the answer...

anyways

OA is: A

and for those who havnt got it... the last line is the conclusion...
