   Answer:   A

請問是在考什麼觀念呀

不知道從何下手

顶！考什么？为什么B错？

我只能排除C不正确，with it skimming 错误。

我觉得D的because of its 好像错误

E错好像是因为make 的用法不正确。应该是make it possible to do(不应该是that)

新东方老师总结make 的用法

make + n1 + n2

make + n + adj

make + it + adj + to do

只是我自己的分析，是否有用仅供参考，

请教B错在哪里？看到say it别扭呢

可能是efficiency上面的错误， according to放在句首的结构被改后，句子中心就转移了吧？
