OG-6疑问，谢谢！

6. In virtually all types of tissue in every animal species, dioxin induces the production of enzymes that are the organism's trying to metabolize, or render harmless. the chemical that is irritating it.

(A)  trying to metabolize, or render harmless, the chemical that is irritating it

(B)   trying that it metabolize, or render harmless, the . chemical irritant

(C)  attempt to try to metabolize, or render harmless, such a chemical irritant

(D)  attempt to try and metabolize, or render harm­less, the chemical irritating it

(E)   attempt to metabolize, or render harmless, the chemical irritant

Although an "-ing" verb such as trying can sometimes be used as a noun, the phrase the organism's trying to metabolize in A is unidiomatic because trying is used as the object of organism's. (是不是表所有格的词后跟的名词不能动作性太强，如这里的trying ？)In B, trying that it metabolize is ungrammatical. The noun attempt could follow organism's; also, it would parallel the noun enzymes, and parallelism is needed here because the sentence uses the linking verb are to equate enzymes and attempt. In C and D, however, attempt to try is redundant. Choice E, which says attempt to metabolize, is best. The phrase the chemical irritant is also the most concise and precise conclusion for the sentence because it clearly refers to the dioxin mentioned earlier.（这道题目到底是怎么翻译的啊？是因为dioxin（简称D）诱发了enzymes（简称E）的产生，而这一产生是有机组织尝试去新陈代谢或产生无害的化学催化剂-即dioxin么？也就是说D诱发E的产生而E的产生又是组织尝试去产生D？）
