Nan: Government subsidies have been proposed in Cariana to encourage farmers in Rochelle, the country’s principal agricultural region, to implement certain new farming techniques. Unless these techniques are implemented, erosion of productive topsoil cannot be controlled. Unfortunately farmers cannot afford to shoulder the entire cost of the new techniques, which are more expensive than those currently used. Therefore, without subsidies, agricultural output in Rochelle will inevitably decline.
Betty: But erosion in Rochelle is caused by recurring floods, which will end next year once Cariana completes the hydroelectric dam it is building across the region’s major river. Therefore, Rochelle’s total agricultural output will stabilize at its present level even without subsidies.
Which one of the following is an assumption on which Betty’s argument depends?
(A) Building a dam across Rochelle’s major river will not reduce any recurrent flooding that occurs in regions of Cariana other than Rochelle.
(B) The new farming techniques that must be implemented to control soil erosion in Rochelle are not well suited to other regions of Cariana.
(C) The current yearly output, if any, from Rochelle’s land that will be permanently under water once the dam is completed will at least be matched by additional yearly output from Rochelle’s remaining land.
(D) The cost to the government of Cariana to operate the hydroelectric dam will not be greater than the projected cost of subsidizing the farmers of Rochelle in the implementation of the new farming techniques.
(E) The government of Cariana has sufficient financial resources both to subsidize its farmers’ implementation of new farming techniques and to operate a hydroelectric dam.

IMO C
The conclusion is that Rochelle’s total agricultural output will stabilize at its present level even without subsidies.
(A) Building a dam across Rochelle’s major river will not reduce any recurrent flooding that occurs in regions of Cariana other than Rochelle. Imo, this is not a required assumption. However, this may strengthen the argument.
(B) The new farming techniques that must be implemented to control soil erosion in Rochelle are not well suited to other regions of Cariana. Irrelevant to the conclusion. We are concerned with the output
(C) The current yearly output, if any, from Rochelle’s land that will be permanently under water once the dam is completed will at least be matched by additional yearly output from Rochelle’s remaining land. Correct. If we negate this statement, it reads: "The current yearly output, if any, from Richelle's land that will be permanently underwater once the dam is completed will not be matched by additional yearly output from Rochelle's remaining land. Thus, if this were true, this would tear apart the conclusion that the total agricultural output will stabilize
(D) The cost to the government of Cariana to operate the hydroelectric dam will not be greater than the projected cost of subsidizing the farmers of Rochelle in the implementation of the new farming techniques. We are not concerned with the cost. The conclusion is about agricultural output.
(E) The government of Cariana has sufficient financial resources both to subsidize its farmers’ implementation of new farming techniques and to operate a hydroelectric dam. Same as D

ARGUMENT
[p] erosion cannot be stopped wo implementing new tech
[p] new tech cannot be implemented wo subsidies
[c] wo subsidies output will decline
[xp] erosion will be stopped after dam is completed
[xc] thus output will be stabilized
ASSUMPTION
Ans (C) if she concludes that output will stabilize, then she must assume that at least part of the land will make up for that which was flooded, or else the output would, in fact, decline.
