费费的这道题比较有意思。

70. A low-pressure weather system is approaching Plainville; rainfall results from about 70 percent of such systems in the Plainville area. Moreover, the current season, spring, is the time of year in which thundershowers, which sometimes result from low-pressure systems, are most likely to occur in Plainville.

Knowing which one of the following, in addition to the information above, would be most useful for determine the probability that Plainville will have a thundershower soon?

A.    the percentage of thundershowers in Plainville that occur in the spring
B.    the percentage of spring rainfalls in Plainville that are thundershowers
C.    the percentage of thundershowers in Plainville that result from low-pressure systems
D.    whether low-pressure systems in other areas are associated with rainfall
E.    whether Plainville has more or fewer thundershowers each spring than do near by towns

答案是B。其中的C看了lawyer的解释后顿然大悟。

应该是说下雨和下暴雨使两个概念吧。好像ｇｍａｔ很喜欢偷换概念。一不留神就错了。

lawyer 怎么解释的， 费费解释上答案是C，我就觉得不对，逻辑大全也挺有趣，啥样的题都有

lazzycat_wxh

[tr][td]lawyer的解释。

C的意思为thundershower百分之几可能性来之于低压天气。如果改为低压天气的百分之几可能性产生thundershower。则为答案。请细心体会其区别。关键看percentage修饰那个。
