extract uranium from seawater, but the cost of doing so is greater than the
price that uranium fetches in the world market. Therefore, until the cost of
extracing uranum from seawater can somehow be reduced, this model of obtaning
uraium is unlikely to be commercially viable.
which of the following would it be most useful to determine in evaluating
the arugment?
The answer is A
Whether the uraium in deposit on the land is rapidly being depleted.
這個答案我可以理解
but the answer C
Whether there are any technological advances that show prmise if reducing the
cost of extracing uraium from seawater.
