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.
Betty uses which one of the following argumentative techniques in countering Alan’s argument?
(A) showing that one premise in Alan’s argument is inconsistent with another premise in his argument
(B) making additional claims that, if correct, undermine a premise in Alan’s argument
(C) demonstrating that Alan’s conclusion is true but not for the reasons Alan gives to support it
(D) presenting evidence indicating that the policy Alan argues in favor of would have damaging consequences that outweigh its positive consequences
(E) pointing out that Alan’s argument mistakenly identifies something as the cause of a trend when it is really an effect of that trend

IMO B
Nan advocates for new agricultural techniques to prevent Rochelle's agricultural output from declining. He supports his argument by stating that without these new techniques, the rich topsoil will get eroded and that the erosion cannot be controlled.
Betty replies by bringing in new piece of information. She says that the erosion is due to the floods, which will stop once the new dam is built.
(A) showing that one premise in Alan’s argument is inconsistent with another premise in his argument Betty does not point out inconsistencies in Nan's argument.
(B) making additional claims that, if correct, undermine a premise in Alan’s argument Yes. Betty makes an additional claim, which would undermine Alan's premise that the erosion cannot be controlled.
(C) demonstrating that Alan’s conclusion is true but not for the reasons Alan gives to support it Betty does not support Nan's conclusion
(D) presenting evidence indicating that the policy Alan argues in favor of would have damaging consequences that outweigh its positive consequences Betty does not say anything about the cons outweighing the pros
(E) pointing out that Alan’s argument mistakenly identifies something as the cause of a trend when it is really an effect of that trend Cause and effect are not mistaken
