首先答案是b a的倒装把did提前 用gave是明确的语法错误

d只有but also

一般来说，not only... but also...连接的是两个递进关系的成分， 题目中的是两个对立成分；

B的，which...从句有问题， 是"the systematic clearing of forests"  "gave consumers relatively inexpensive houses and furniture"  而不是farmland!  按照GMAC的语法解释，修饰词/从句必须紧邻被修饰部分； 再者，create farmland和give consumers inexpensive stuff...是对等的， 应该用and连接才符合parallelism!

A的did gave， 如果不是typo的话， 的确很低级！ 改成give， a就无可非议；

这样的话， 只有d 语法和逻辑都说的过去；
