Q23:
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.
answer is B, only one question, logging 是个名词,which removes only selected trees, which 指代的是logging, 但它怎么能发出remove的动作呢,好歹也应该是is removal 吧。
请多指教。
sorry,sorry, 发错地方了
