Because there are provisions of the new maritime code that provide that even tiny islets can be the basis for claims to the fisheries and oil fields of large sea areas, they have already stimulated international disputes over uninhabited islands.

A.Because there are provisions of the new maritime code that provide that even tiny islets can be the basis for claims to the fisheries and oil fields of large sea areas, they have already stimulated

B.Because the new maritime code provides that even tiny islets can be the basis for claims to the fisheries and oil fields of large sea areas, it has already stimulated

C.Even tiny islets can be the basis for claims to the fisheries and oil fields of large sea areas under provisions of the new maritime code, already stimulating

D.Because even tiny islets can be the basis for claims to the fisheries and oil fields of large sea areas under provisions of the new maritime code, this has already stimulated

E.Because even tiny islets can be the basis for claims to the fisheries and oil fields of large sea areas under provisions of the new maritime code, which is already stimulating

本题答案为B,可我错选了D,根据OG的解释， D项的错误原因是this指代不清楚。
那为什么B项里it就指代清楚了呢？在这里it是指代maritime code的。
关于指代的问题一直很困惑，永远搞不清先行词，请大侠赐教！！！

this作为代词不可独立出现，后面必须加上一个相对概括性的名词，两者一起指代之前出现的某个事物

这道题的话要重点关注一下原句中they的指代呐

嗯，研究了下Manhattan 现在清楚了，谢谢

这道题的话要重点关注一下原句中they的指代呐
1.首先原句中，从逻辑来看they想指代the new maritime code ，但实际上不能指代
2.D中this不能单独在句中指代名词的，this是不同于they的，关于这一点可以看曼哈顿语法，很详细
3.C和E项句子结构不完整
以上只是个人观点
