19: Sonya: The government of Copeland is raising the cigarette tax. Copeland’s cigarette prices will still be reasonably low, so cigarette consumption will probably not be affected much. Consequently, government revenue from the tax will increase.
Raoul: True, smoking is unlikely to decrease, because Copeland’s cigarette prices will still not be high. They will, however, no longer be the lowest in the region, so we might begin to see substantial illegal sales of smuggled cigarettes in Copeland.
Raoul responds to Sonya’s argument by doing which of the following?
A: Questioning the support for Sonya’s conclusion by distinguishing carefully between No change and no decrease
B: calling Sonya’s conclusion into question by pointing to a possible effect of a certain change.
C: Arguing that Sonya’s conclusion would be better supported if Sonya could cite a precedent for what she predicts will happen.
D: showing that a cause that Sonya claims will be producing a certain effect is not the only cause that could produce that effect
E: pointing out that a certain initiative is not bold enough to have the predicts it will have
19题看大家的答案是B比较多,我倾向于选D
理由:Sonya的言谈中的一个effect: so cigarette consumption will probably not be affected much,是因为 Copeland’s cigarette prices will still be reasonably low
而Raoul根据这个effect提出了不同的理由 Copeland’s cigarette prices will, however, no longer be the lowest in the region) substantial illegal sales of smuggled cigarettes in Copeland
并没有发生effect的改变,而是产生这个effect的原因在两个人的话语中有了不同. |
