  Q.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.

OA : A,
However, to me option 'B' looks very close too. Can someone please elaborate the answer.

  hi suman,
yes indeed the ans shld be A and it cant be B. In CR questions, we can't add knowledge from our pocket. Though we know Green House gases play a role in global warming, we can't consider such an option coz the passage above doesnt state anything about it...

Guys if anybody got a better explanation plz shoot...

regards,
GC

  Hi Suman,
             This is shubham yadav i am fully  agree  with u but we all know that  this is G-mat examination so there r many answer which  r correct but we r to find best one.
                                             Because we r asked that which one support the conclusion & that should be assumption.so we find two things first -
1-conclusion-Global warming is prevailing & human beings r responsible for that  & it will bear a horror role in future(indicating to coastal distroyment).
2-assumption-it comes after premises &before conclusion So that is not written in passage at all.
            ''elimination is the best approach for R C ''
1- if we give one glance to E option then we'll see that it is given in passage so it is premise not assumption
2-D option is obstract choice & it is not supporting our conclusion.
3-C option is premise also.
4-B option says that individuals will not aware & they will not do what they could do.
                       but please see that is there any point from where we can assume that?
                      in passage there is only one line for people that they r responsible for all cause.
So we don't know the exact answer but we know all wrongs.
thats why A is correct one.
