这道题真的选B嘛？！

我觉得是选B，你看A选项：
although improved efficiency in converting harvested tress into wood products may reduce harvest rates, it will stimulate demand by increasing supply and lowering prices, thereby boosting consumption.

先不说thereby boosting consumption的修饰错误
“it will stimulate demand by increasing supply and lowering prices”
这里，我觉得，一般句子里面如果出现表动作的词(比如这里的increasing and lowering)，就肯定要有主语，这个主语要么在句子中，要么可以很明显的看出来不在句子中，而这里，感觉好像it做了increase和lower这两个动作的主语，it指代improved efficiency in converting harvest tress into wood products，这样不符合逻辑。

我觉得,increase和lower, 这两个词，找动作发出者，好像怎么都不太对，所以B中用了because of~~~
一家之言哈~~~

个人认为是选B，it 无指代

找到一个句子，verb 2nd上的：
......shifting a portion of health-benefit costs back to the workers not only helps to control the employer’s cost, but also helps to limit medical spending by making patients more careful consumers.

看后半句：
shifting a portion of health-benefit helps to limit medical spending by making patients more careful consumers.
这里我可以说，making ...的主语是shifting a portion of health-benefit helps to limit medical spending，
因为shifting...会导致patient more careful consumers.

而although improved efficiency in converting harvested tress into wood products may reduce harvest rates, it will stimulate demand by increasing supply and lowering prices, thereby boosting consumption.

it -->efficiency
efficiency increase and lower....
逻辑不通呀~~

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

Verb form; Grammatical construction; Idiom

The correct version of the sentence must clarify the sequence of two effects of improved efficiency in converting harvested trees into wood products: first, stimulating demand and second boosting consumption. The first of these effects is itself caused by increasing supply and lowering prices.

A. Correct. The subject of the independent clause it clearly restates the subject of the dependent clause efficiency, and the use of active voice in both clauses clarifies the although relationship announced at the beginning of the sentence.
B. The passive voice in the independent clause obscures the sentence's meaning, making the cause of increasing supply and lowering prices unclear; the relationship between efficiency and demand is similarly unclear.
C. The preposition of is not idiomatic in the context of this sentence; the referent of the relative pronoun which is ambiguous.
D. The passive phrase of harvested trees being converted is wordy and unclear.
E. This sentence obscures the identity of the efficiency that may reduce harvest rates; the passive construction in the independent clause causes further ambiguity. (What will stimulate demand? How are increasing supply and lowering prices causally connected to demand?)

The correct answer is A.
