请教一道GWDboldface。。。

GWD3-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?

A. It is the main conclusion of the argument.

B. It is an objection that has been raised against the main conclusion of the argument.

C. It is a judgment that the argument opposes.

D. It is a finding that the argument seeks to explain.

E. It provides evidence in support of the main conclusion of the argument.

在A和D之间纠结。。。我觉得说他是explanation也说得过去吧。。。但是说是main conclusion貌似也OK ....纠结了。。。请教各位。。。

Premise:

1.Deer hunting season（hunters hunt deer）, black bears died→a

number of bears had recently fed on deer.

2.Black bear population has risen sharply in the past ten

years------------bears↑

Conclusion:

Black bears have also played an important role in this decline.

(Pay attention to “also”)


Try to understand the author’s intention of writing the article,

the author didn’t find that the bears are to be blame. He just

proves it.

Some people say hunters are the only reason for which deer

population decrease. But the author doesn’t think so, he puts

forward some premises, and then draws a conclusion that hunters

is not the only reason, bears should also to be blame. So the BF

is not a finding that the argument seeks to explain, it is the

main conclusion that the argument seeks to prove.
