我觉得在解GMAT题的原则上还是应该把握整体的来看题干作者的思路,然后比较选项和作者的思路的一致性。尤其是几个选项从逻辑上讲都符合条件的时候。
题干最后一句话:However, this fact is either beside the point, since much irradiated food is eaten raw, or else misleading, since ________。明显包含两个部分,正确的答案应该和第一个部分的解释对称.
把c和e分别放进去:
C: However, this fact is either beside the point, since much irradiated food is eaten raw, or else misleading, since cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods. 感觉上第二部分的解释完全可以涵盖整个句子,如果作者的思路是想说irradiation和cooking不相关,所以proponents 是misleading, 完全可以省略掉"since much irradiated food is eaten raw”,因为这种不相关同样可以用来指责proponents是 beside the point。一句话就完了:However, this fact is beside the point and misleading, since cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods
E: However, this fact is either beside the point, since much irradiated food is eaten raw, or else misleading, since for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded. 这里有一个对compound的理解的问题,Webster的上的解释是to put together (parts) so as to form a whole. 所以这里的意思VB1的减少是叠加的。 如此一来作者的思路就清楚了:那些鼓吹者列举的事实对于生吃的食品来说是没有意义的;而对于煮熟的食品来说是误导,因为VB1在放射处理和烹饪两个过程中的损失是叠加的。
个人感觉GMAT的逻辑并不太注重正规的逻辑推理,而是注重对某一问题关键点(Key point)的把握。毕竟对管理者的要求和对律师的要求是不同的。
