Ecologist: Forest fires, the vast majority of which are started by lightning, are not only a natural phenomenon to which all forest ecosystems are well adapted, but are required for many forests to flourish. Forest fires facilitate the opening and spreading of seed pods, prevent an overabundance of insects, and promote the diversity of forests by preventing certain varieties of aggressive weeds from dominating other species. In view of this, systematic attempts by human beings to prevent or control forest fires are ill-advised and shortsighted; forest firs should be left alone and allowed to burn themselves out naturally.
The conclusion drawn above follows logically if which one of the follwoing is assumed?

B. Protection of forests and their ecosystems is the only legitimate reason for attempting to prevent or control forest fires(OA).

E. If the health of an ecosystem is threatened by insects or other predators, human beings should not intervene to block that threat.

Why E is not right?

先說說我的想法, (當然還是要等待板主的專業文啦)
E無關, human beings should not intervene to block that threat 和 forest fire無關, 另外, 要是取非, If the health of an ecosystem is threatened by insects or other predators, human beings should intervene to block that threat. 對原文也沒有影響
(B)選項, 原文說forest fire 事實上對於ecosystem是有幫助的, 所以若是protect forest的話, attempt to prevent or control forest fire是不必要的, 除非有其他原因

题目说“Forest fires”，E 的 scope 不对。
