GWD-8-Q20:
Not only did the systematic clearing of forests in the United States create farmland (especially in the Northeast) and gave consumers relatively inexpensive houses and furniture, but it also caused erosion and very quickly deforested whole regions.

A.        Not only did the systematic clearing of forests in the United States create farmland (especially in the Northeast) and gave consumers relatively inexpensive houses and furniture, but it also
B.        Not only did the systematic clearing of forests in the United States create farmland (especially in the Northeast), which gave consumers relatively inexpensive houses and furniture, but also
C.        The systematic clearing of forests in the United States, creating farmland (especially in the Northeast) and giving consumers relatively inexpensive houses and furniture, but also
D.        The systematic clearing of forests in the United States created farmland (especially in the Northeast) and gave consumers relatively inexpensive houses and furniture, but it also
E.        The systematic clearing of forests in the United States not only created farmland (especially in the Northeast), giving consumers relatively inexpensive houses and furniture, but it

the correct answer is D.
We focus on the construction of not only but also, the Manhattan staff pointed out that the construction was inappropriate 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.
"

Hope it helps!

谢谢楼主，我原来各种纠结，还想为什么不用not only。我还想补充问一问，d选项中的 it 会不会有指代不清楚的嫌疑呢？
