Q2:

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?

1. It is the main conclusion of the argument.
2. It is an objection that has been raised against the main conclusion of the argument.
3. It is a judgment that the argument opposes.
4. It is a finding that the argument seeks to explain.
5. It provides evidence in support of the main conclusion of the argument.

为什么不选A,main conclusion是Hunters alone are...bears have also ...我的思路是反对Alone.

The answer is A!

just check whether your answer script is right.

可是我的答案檔案是选Ｂ哦

我也觉得Ｂ正确，因为Hunter的第一句话是结论（即使不是他说的），而第二句话是为Hunter們去辩护。
