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
題中 as little risk as one .....
跟 a risk as little as one....
有什麼分別嗎??且 這提要怎麼解阿??
原句： toxic substances that present as little risk as one in a million chances to cause cancer.
此题是在做宾语比较，两种形式：as little risk as one 和 a risk as little as one 都可以。
但是请注意句子的主语substances 是复数，用substances present a risk 是不是不太好呢？
Open to discuss....
