Question ID:PT21 S2 Q12 Passage:Alan: 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. Stem:Betty uses which one of the following argumentative techniques in countering Alan’s argument? Correct Answer Choice:BChoice A:showing that one premise in Alan’s argument is inconsistent with another premise in his argument Choice B:making additional claims that, if correct, undermine a premise in Alan’s argument Choice C:demonstrating that Alan’s conclusion is true but not for the reasons Alan gives to support it Choice D:presenting evidence indicating that the policy Alan argues in favor of would have damaging consequences that outweigh its positive consequences Choice 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
