标题: 跟大家一起讨论一道题

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.

	as little risk as one in a million chances to cause
	as little risk as one chance in a million of causing
	as little risk as one chance in a million that it will cause
	a risk as little as one chance in a million for causing
	a risk as little as one chance in a million for it to cause

答案是B，我就觉得有点晕

用排除法
1. risk表示风险的统称的时候，是不可数的，所以a risk 错误，而且A选项中One代指risk也是错误的的
2. C选项太累赘了
