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

答案是D 我想知道B为什么不对。 还有but also可以单独用吗？

B 中国which指代 farm, 然而带来house和家具的不是farm ，所以逻辑错误

LZ， not only,...but also的结构是一种强调but also的结构，但是它有个特点就是强调的两边都是同正同负的，也就是not only...表达正，but also。。。也表达正的态度；反之亦然

但是这题可以看出是一边正，一边坏的，所以就不该用not only...but also的结构了

这里but it also，it是说the systematic clearing，but后面是一整句话。
意思是这个clearing带来了好的方面，但是它也带来了不好的。。。转折
