Which of the following, if true, would most weaken the author’s conclusion in lines 18–22 ?
我的思维: 文章第一段末尾说， if not self-regulating, may at least be regulated by an agent more intimately connected with the insect than are predatory birds or parasites. 文章说跟predatory birds 或者parasites的关系不大，那么如果是C选项，就证明它跟predatory birds 和parasites的关系增大了，就可以weaken问题了吧？ 还是说我的思考方向错了？B的答案不是太理解，也不知道怎么来的。 麻烦老师解释下（我不确定我起不起的来，冬令时，真的太早了，如果我每到麻烦老师还是讲下，谢谢啦！！）
