LSAT-9-1-3

Sheila: Health experts generally agree that smoking a tobacco product for many years is very likely to be harmful to the smoker’s health.

Tim: On the contrary, smoking has no effect on health at all: although my grandfather smoked three cigars a day from the age of fourteen, he died at age ninety-six.

A major weakness of Tim’s counterargument is that his counterargument

(A) attempts to refute a probabilistic conclusion by claiming the existence of a single counterexample

(B) challenges expert opinion on the basis of specific information unavailable to experts in the field

(C) describes an individual case that is explicitly discounted as an exception to the experts’ conclusion

(D) presupposes that longevity and health status are unrelated to each other in the general population（A）

(E) tacitly assumes that those health experts who are in agreement on this issue arrived at that agreement independently of one another

   这道题我觉得a与c都对呀？

   是不是c中的explicity不合适呀？

是啊，我也刚刚做过这题，我作对了，但当时做的时候就觉得两个选项很相似，只是（A)直接说了作者的意图是什么，而（C)说了作者的counterargument的实际结果将会怎样……

其他的我就不知了，但感觉上（A)更直接一些，还是邀请NN讲一讲啊：）
