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 abundant on the earth’s surface, then in deep water it IS expensive. And Vice-versa.

Ask for further assistance if you do need.

If the ore is abundant on the surface itself, why would we want to recover it from deep water?

I feel that there should be a contrast word to signify the importance of deep water process. Isn't so?
For instance, Ore in earth's surface is abundant, but deep water ores are not inexpensive.

Guys, this is not a critical reasoning question.

Considering that on the surface the ore is abundant and consequently the costs to obtain it are not that high, then in deep water, the process will not going to become inexpensive. It will more costly.

On the surface the cost is 10$, suppose, in deep water is 11$ (it must be higher for mandatorily, because of is reasonable to think that even the gasoline of the bathyscaphe cost more to go down at 1000 meters rather than 100 meters, just to make the idea), then 11$ is still more expensive than 10$.


Therefore, in comparison, it is very difficult that in deep water the costs will be at 9$ and on the surface will be stable at 10$.

Deepwater costs always will be \(>\) of the surface costs.

This question is meaningless because we should not ask this about the question. It is npt a critical reasoning question.

Why we will pick the ore in deep water rather than on the surface.

You have to pick two words that best fit the meaning of the question as a whole.

May be we can think in this way...give emphases on underline part.

Since frequently located surface ore is (i)____________ and recovery is less costly; recovery of underwater ore is not (ii)____________ procedure.

frequently is hint for (i)

Less costly is hint for (ii)

Surface water is opposite of under water in this case

Hence the answer is logical.

i am not that knowledgeable.... question is missing some important clue to get correct answer...

Since a large amount of the ore frequently located in riverbeds is (i)____________ on the earth’s surface, where the processing of chemicals is less costly, recovery of underwater ore is not likely to become a (ii)____________ procedure.

The two portions above are the clues to B and E as answers

I hope now is more clear

The highlighted words clue us into abundant as the choice for the first blank.

And since the processing of the ore on the earth's surface is already less costly, recovery of underwater ore is not likely to become an inexpensive procedure.

We can easily reject valuable and rejected as choices for the second blank.

The phrase "less costly" suggests a comparison with other methods of extraction, in this case underwater. Therefore, amongst the three choices, inexpensive fits well.

But you are right in your question, because less costly does not automatically imply inexpensive.

This is the problem with non-ETS questions. They are not perfect.

An ETS question is mathematical and even an English literature student can answer a science-related TC or SE or even an RC without bringing in outside knowledge, and vice versa.
