prep答案选D，你们的答案好像不对呀。

逻辑关系是转折时，不能用not only...but also...
not only...but also表示互相强调

From Manhattan:
Even if it were used with proper parallelism, the "not only ... but also" construction still wouldn't be appropriate here. Rhetorically, the "not only ... but also" construction is used for 2 parallel items that reinforce each other.
Example: Weight training not only increases muscle mass and strength but also boosts bone density. --> notice that the two effects mentioned are both positive effects.

In this sentence, the 2 effects are contrasting: the first half (farmland/ houses/ furniture) is positive, but the second half (erosion/deforestation) is negative. Thus, "not only ... but also" is inappropriate; just use traditional "but (also)", by itself, instead. that's exactly what choice (d) does.

以下引自旧贴（讨论很多）：http://forum.chasedream.com/archiver/GMAT_SC/thread-55382-20.html

A.    not only 位于句首时，所引导的句子要用倒装，give和create是and连接的两个并列成分，而时态已经被did提前，只能用原形。所以这里gave错。But it also没有错。例见大全354.
B.    Which定语从句修饰farmland，逻辑意义错误，是systematic clearing给了consumers houses and furniture，不是farmland。
C.    But also之前无谓语，片段。
D.    正确。But it also,转折前后句，说明systematic clearing既带来了好东西，也带了坏东西，also的使用，精妙。
E.     Giving修饰created,改变了原来的句意：并列的两个动作。the systematic clearing of forests  not only... but ( also) ,主语已经存在了，but 后面的It多余
