答案是A，选了B。 把第一句话当做了conclusion, 觉得第二句应该是跟第一句反的，所以是反对conclusion的。为什么把第一句和第二句放在一起当做是一个conclusion? 谢谢

因为英老师说过main conclusion不可能出现在文章的首和尾，所以一上来就把A给杀了，求解释 Hunter: Hunters alone are blamed for the decline in Greenrock National Forest's deer population over the past ten years. Yet clearly, （black bears have also played an important role in this decline）. In the past ten years, the forest's protected black bear population has risen sharply, and examination of black bears found dead in the forest during the deer hunting season showed that a number of them had recently fed on deer. In the hunter's argument, the boldface portion plays which of the following roles? It is the main conclusion of the argument. It is an objection that has been raised against the main conclusion of the argument. It is a judgment that the argument opposes. It is a finding that the argument seeks to explain. It provides evidence in support of the main conclusion of the argument.
