A. which is the removal of only selected trees, as well as surface fires, burning

B. which removes only selected trees, or surface fires that burn

C. which removes only selected trees, along with surface fires that burn

D. removing only selected trees, or surface fires, burning

E. removing only selected trees, as well as surface fires that burn

这一看上去都是很简单的not only, but also, either or,结构，但怎么做出来就是和答案不一样呢。。。

我的答案是D，B。
第一题应该不是套用not only, but also吧。前后两个分句说的完全是相向的意思，而不是同向的意思，所以只能用but来表示转折；
第二题确实是either...or...，不晓得你是什么答案？或者正确答案是什么？
