Soil quality is one of the most important factors affecting the growth of crops. Farmers often look for ways to improve soil conditions in order to increase crop production. One possibility involves the planting of dynamic accumulators—plants, such as comfrey, that may draw up significant quantities of beneficial nutrients from beneath the topsoil. Numerous reports have shown that plants grown in areas alongside dynamic accumulators are healthier and more abundant than those grown in areas without dynamic accumulators.

Which of the following would be most useful in evaluating the claim that planting dynamic accumulators would help farmers increase crop production?

(A) Would tending to dynamic accumulators increase the costs of crop production?

(B) Are there solutions other than planting dynamic accumulators that would be more effective at increasing the farmers’ crop production?

(C) Are there plants other than comfrey that would draw up a greater number of nutrients?

(D) Are any of the plants in the reports the types of crops grown by farmers?

(E) Would planting dynamic accumulators provide any additional benefits to farmers other than increased soil quality?

The argument's main claim is that the dynamic accumulators are beneficial as (1) they might improve soil conditions by drawing up nutrients and (2) research has showed that they are beneficial.
The related evidence should strengthen one of these two claims, so we can just skim through the options, looking for the one that does. (a Precise approach)

(A) costs are irrelevant.
(B) our argument is only about accumulators, not about a comparison. No
(C) we don't care about other plants.
(D) This is relevant -- if this is correct then (2) is strengthened, and if it is incorrect then (2) is negated
(E) also out of scope.

(D) it is.

A. Wrong. The argument is concerned with production, not cost, hence this option has no impact.
B. Wrong. The argument is not concerned with any other solutions, hence this option is irrelevant.
C. Wrong. The argument is not concerned with dynamic accumulators, but plants grown alongside dynamic accumulators, so this option is out of scope.
D. Correct. If most plants grown by farmers alongside dynamic accumulators are not mentioned in the report, we can't conclude that the discussed solution is a fit for the problem at hand. However, if they do, then the solution gets a go ahead.
E. Wrong. The argument is not concerned with additional benefits but only seeks better production, thus this option doesn't affect the argument.
