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 great impact

答案是A 实在是没理解at least as 的用法请大牛们解答～～～谢谢啦

有道理，但是B为什么不对呢

GMAT一个较常见用法：at least as ... as
此处省略后面的as，表达的意思是即使A可以影响产量和财务能力，管理层决策也可以对公司有至少（at least）相同大（as great）的影响力，而B只是说了有影响并没有把原句的让步关系表示出来
个人理解~探讨~
