Rising global temperatures have led to ecological issues that have affected the growth of the staple crop, madinga, in Guadelaga. As this process has continued, the output of madinga in Guadelaga has decreased. If temperatures continue to increase, the people of Guadelaga will soon have to change their diets, as they will no longer have access to sufficient madinga.

The answer to which of the following would be the least useful in assessing the validity of the above conclusion?

(A) Are there certain strains of madinga that are not currently commonly grown in Guadelaga and that would thrive in the new conditions?

(B) Are there places other than Guadelaga where madinga can be grown and where temperatures can be expected to remain similar to or lower than temperatures currently seen in Guadelaga?

(C) If new measures being adopted were to stabilize global temperatures near current levels, would the size of Guadelaga's madinga crop stabilize near current levels?

(D) Would using relatively complex and currently rarely used biodiverse farming methods ameliorate the effects of higher temperatures on the ecology that supports the growth of madinga?

(E) To what degree does Guadelaga's current madinga crop exceed the dietary consumption of madinga by the people of Guadelaga?

Could you explain why c and not b? B says it can be grown elsewhere but we don't know whether this will be exported to the effected area.
Also, can you please explain the wording of choice C?
Thanks

Getting this one right requires noticing exactly what the conclusion of the argument is.

Here's the conclusion.

"If temperatures continue to increase the people of Guadelaga will soon have to change their diets, as they will no longer have access to sufficient madinga."

Here's what C says. (I edited C to remove the wording "bounce back", which may not be familiar to non native speakers.)

"If new measures being adopted were to stabilize global temperatures near current levels, would the size of Guadelaga's madinga crop stabilize near current levels?"

While it is true that B does not give one a definite answer one way or the other regarding the validity of the conclusion, the reason C is the least useful in evaluating the conclusion is that the conclusion is predicated on temperatures continuing to increase, whereas the answer to C would provide information regarding what would happen should temperatures stabilize.

Noticing exactly what the conclusions are is a key aspect of getting right answers to CR questions, and making that point is a key aspect of this question.

Here's a similar one that you could use to get more practice handling this kind of situation.
