答案选B,我选E. B & E难道不是从不同的方向，去排除一些可能的误解，所以，两个都可以选，我当时觉得E好像和主题更接近一些？？作者: wyyavv 时间: 2012-1-8 06:42
E: variety of cigarettes与sales无关
B: 取非削弱。如果information available to consumers on the health risks of smoking有变化，可能这个information才是sales变化的原因，削弱。
常识判断也是B优于E作者: socat123 时间: 2012-1-10 21:05
如果E要成立，还得一个前提：greater variety of cigarettes会导致sales的提高作者: kurtsniper 时间: 2012-1-11 21:05
谢谢！！我还是没被说服。如果information available to consumers on the health risks of smoking可能是sales变化的原因之一，难道 variety of cigarettes 就不是SALES可能变化的原因之一么？？作者: kurtsniper 时间: 2012-1-11 21:05
