GPREP qn.

by aj5105 » Wed Oct 08, 2008 4:39 am
Most of the world's supply of uranium currently comes from mines. It is possible to extract uranium from seawater, but the cost of doing so is greater than the price uranium fetches on the world market. Therefore, until the cost of extracting uranium from seawater can somehow be reduced, this method of obtaining uranium is unlikely to be commercially viable.

Which of the following would be most useful to determine in evaluating the argument?

A. Whether the uranium in deposits on land is being rapidly depleted
B. Whether most uranium is used near where it is mined
C. Whether there are any technological advances that show promise of reducing the cost of extracting uranium from seawater
D. Whether the total amount of uranium in seawater is significantly greater than the total amount of uranium on land
E. Whether the uranium can be extracted from freshwater at a cost similar to the cost of extracting it from seawater

E talks about comparison between fresh water and sea water.
I think it is not the answer because IMO freshwater has nothing to do with the argument.
Its not part of argument.

I will go with D

whats the OA??

IMO C.

D cannot be the answer, because we have to evaluate the method of mining by reducing cost. and D talks about the amount of uranium which does not help or weaken the argument at all.

I will go with A as well

Conclusion - Until the cost of extracting uranium from seawater can somehow be reduced, this method of obtaining uranium is unlikely to be commercially viable.

This becomes valid only when uranium cannot be extracted from land.

A for me 2....

wats d use in extracting uranium from seawater when it can be easily obtained from land itself..

A helps us to evauate this...

not
C bcoz:we cannot determine if the reduction in cost will be lesser than the price of uranium in world market.

not D bcoz: we r not comparing the quantities of uranium available on land and in seawater.the question is which one is more cost effective..

thx

I'd say A but I'm afraid more because of my intuition than any logic.
