One study found that although government policy and the industrial sector in which a company operates can influence its productivity and financial strength, management decisions have at least as great an impact on a company’s performance.
A    management decisions have at least as great an impact
B    decisions by management have a great impact
C    manager decisions impact greatly
D     decisions by a company’s management impact greatly
E      what a company’s management decides has a greater impact

A 这是一种as as的省略结构

用于 先描述比较对象
例句
Jay has the most fans in youth，lil‘S is as popular
周结论在年轻人中最受欢迎，小S也很受欢迎

我也疑惑在a中的at least as哪儿，网上搜了一下，原来这个题考的是平行啊！其实这个题也就a是最优了的。

management decisions 和a company’s performance。平行。

另外关于at least as哪儿，大牛说如果比较部分前面出现了at least as了，后面的as是可以省略的。例子如下：
1.Bob makes a mean pizza, but Fred's spaghetti is at least as good.
2.Die Hard 2 was a thrill ride from start to finish, but Die Hard 4 was at least as exciting.
