Although improved efficiency in converting harvested trees into wood products may reduce harvest rates, it will stimulate demand by increasing supply and lowering prices, thereby boosting consumption.
A.in converting harvested trees into wood products may reduce harvest rates, it will stimulate demand by increasing supply and lowering prices, thereby boosting
B.in converting harvested trees into wood products may reduce harvest rates, demand will be stimulated because of increasing supply and lowering prices, which boost
C.of converting harvested trees into wood products may reduce harvest rates, it stimulate demand by increasing supply and lowering prices, which boosts
D.of harvested trees being converted into wood products may reduce harvest rates, it will stimulate demand, because it will increase supply and lower prices, thereby boosting
E.when harvested trees are converted into wood products may reduce harvest rates, demand will be stimulated because of increasing supply and lowering prices, which boost

答案是A。
语法中which不能够指代句子，但如果像B的表达…… because of increasing supply and lowering prices, which boost，这边because of后面加的是一个短语，整个也是一个短语，那
1.which能够指代because of increasing supply and lowering prices 整个短语吗？
2.which能够指代increasing supply and lowering prices吗，还是只能指代lowering prices，还是只能指代prices？

提前拜谢！

顺便问一下这里boosting也是修饰it= improved efficiency的吧？

我觉得选项里的which要表达的是修饰前面整个事情但是which不能指代事情所以都不对

任何情况下，1都是不对的。

在gmat的范围内，2即使不是错，也基本不是最好的，因为制造了ambiguity。不过我觉得日常应用，which后面能解释清楚到底修饰的是哪一部分，是可以的。
