EC has seen annual per capital consumptin of cigaretts declines from over 125 packs per person to about 60, more than twice as great as that

这道题目看着就比较晕完全没有思路．．．谁说说，答案给的是Ｄ

根据A decade after,确定主句使用现在完成时，排除ABC,

E的话，没有表达原文意思，原文比较的是a drop, E里面比较的是60，不对！

我是这样想的！请大家多指教！

A decade after initiating the nation's most comprehensive and aggressive antismoking program,

决定了主语必须是California ，排除A B C

E 中的per capital  和per person 重复，排除。
