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.

A works; if there are new developments that WILL divert rising seas, then the cities will not be destroyed, and the argument falls apart.

B seems applicable, but we have no way of knowing how consumers becoming more aware will affect the alarming rise in sea levels.

C is irrelevant to the conclusion; the argument does not say that the destruction will be equal.

D is irrelevant; this could make the city destruction worse, but it doesn't have to be true for the conclusion to be true.

E is irrelevant; whether it is the sole factor or one of several factors, it still has an impact.
