以下是引用东岸老男人在2007-12-9 0:04:00的发言：

楼主这么说是认为文中所说的：

The very largest trucks—those with three trailers—had less than a third of the accident rate of single-and double-trailer trucks. 

是根据Partoria本身的统计数据。但文中并没有说明这一点。如果选A等于又引入一个新的assumption。

这道题目E应该是无关选项，但A也有不严密的地方。

I think A is a perfect "other reasons" type of answer, without any demerits.

It means the lower accident rate of three-tailer trucks is not because of its own merits, but becuase of its cautiousness -- It only travels in those sections of highway where traffic is less than usual. If it travels in normal sections of the highway, it probably will be as dangerous as the other two type, or even more dangerous.

A 选项 意思是目前这些三拖是用在较少车次的高速公路上—— 因为车少，所以发生事故的概率小—（ 他因型削弱）E 选项 ，我也错选了，payload 要不是载重 要不就是薪酬的意思，文章被有背景可以判断薪酬或者载重和事故发生频率的关系
