Most of the world's supply uranium currently comes from mines. It is possible to extract uranium from seawater, but the cost of doing so is greater than the price that uranium fetches on the world market. Therefore, until the cost of extracting uranuim from seawater can somehow be reduced, this methold of obtaining uranium is unlikely to be commercially viable.
which of the follwing would it be most useful to determine in evaluating the argument?
A: whethwe the uranium in deposits on land is rapidly depleted
C:whether there are any technological advances that show promise of reducing the cost of extracting uranium from seawater.
