Thanks, Why is the second blank inexpensive? There appears be no logical link(without calling upon outside knowledge) between the abundance of of the ore on the land surface and the fact that a process of extracting ore in the river would be expensive.

The clue for the second blank is on the earth's surface, where the processing of chemicals is less costly." Underwater recovery, in contrast, would be more expensive. The second blank describes what's not true of the procedure, so use a word that means low-cost Cost-effective is a close match. Use the same due for the first blank. If the processing of ores from the surface is less costly, those ores must be plentiful. Abundant is a good match.


Ask if something is still unclear to you.

@carcass
I agree with @newtaraday. How do we know that underwater recovery is an expensive process?

IF the cost is less costly because the ore is abundanton the earth’s surface, then id deep water it IS expensive. And Vice-versa.

Ask for further assistance if you do need.
