标题: 请教PREP2 9

9. (24819-!-item-!-188;#058&001693)

The Environmental Protection Agency frequently puts mandatory controls on toxic substances that present as little risk as one in a million chances to cause cancer.

(A) as little risk as one in a million chances to cause

(B) as little risk as one chance in a million of causing

(C) as little risk as one chance in a million that it will cause

(D) a risk as little as one chance in a million for causing

(E) a risk as little as one chance in a million for it to cause

正确答案是B，我想问一下as和as之间的little risk的比较怎么回事儿啊？little risk和one chance对比吗？谢谢大家。

little risk较少风险，属于一个概率问题，one chance in a million 也属于一个概率问题，可以比较。

这道题考的chance of doing，其他都错

as little risk as 1/1000000

a risk as little as 1/1000000

这两种表达有什么区别请问

不是应该为as little as吗？那就是risk在和一个数在比了？？？
