Past assessments of the Brazilian rain forest have used satellite images to tally deforested areas, where farmers and ranchers have clear-cut and burned all the trees, but such work has not addressed either logging, which is the removal of only selected trees, as well as surface fires, burning down individual trees but do not denude the forest.

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

   Answer: D

请问版主,该题是D,还是B? 感觉有的答案是B,有的答案是D.B中either logging, which removes only selected trees和surface fires that burndown individual trees but do not denude the forest是否对称?

看划线后面的 and do not

我的上面不是“and do not”,而是“but do not ”.

继续请教为什么D错？

either logging, removing only selected trees, or fires, burning down individual trees butdo not denude the forest.

D以上同颜色的对称啊，难道是burning down ...和do not denude 也需要对称？

谢谢
