risk是可数名词，应加a 吧,所以A选项不对吧。我选B。

我也选的是B.可是大全解释上说reason和because of 重复,但是他的解释没有说服力。我见过这种用法啊.for example:

The reason why I am late is because I missed the bus.

不知道有没有别人有同样的疑问。

risk 是不可数的

because of 后面跟着是名词,所以如果前面有reason,because of应该省略

和你上面的because从句是两回事

dearjane

because of 只能做状语不能做表语

RISK 是单数是GMAT考试里的规定吗? 在任何字典里都有RISK做复数的例子啊.

正因为BECAUSE OF 是介词,所以后面才不跟句子.

主语是leaking, 后面的along with...是作状语吧？我想。

水模样

The reason ...... is because of ......好像看上去不太合理,

还有一个很明显的错误是主谓不一致( are 应改为 is )

B的明显错误在于没有任何理由的引入因果关系，改变了句子中心，另外，the reason is that,not because of
