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.
which is the removal of only selected trees, as well as surface fires, burning
which removes only selected trees, or surface fires that burn
which removes only selected trees, along with surface fires that burn
removing only selected trees, or surface fires, burning
removing only selected trees, as well as surface fires that burn
A选项：首先，定语从句which is the removal of only selected trees有误。将先行词代入从句则有：
logging is the removal of only selected trees.
logging is the removal
另外，either…. as well as…搭配错误，应该用either…or…。
最后，现在分词短语burning down individual trees做surface fires的定语是没有问题的。但是，注意到未划线部分but do not denude the forest在逻辑上也应是surface fires的定语，因此burn事件和denude事件应是平行的，即，burning down individual trees需改为that burn down individual trees。
D选项：本选项迷惑性最大。平行触发语either…or…连接的平行应是两个名词的平行，即，either A or B。这和两个名词身后的定语在形式上是否平行没有任何关系。本选项的错误是现在分词短语burning down individual trees和denude事件不平行。
E选项：either…. as well as搭配错误，应该用either…or…。
