下周就考了，再次求助

Q12:

Some species of Arctic birds are threatened by recent sharp increases in the population of snow geese, which breed in the Arctic and are displacing birds of less vigorous species.  Although snow geese are a popular quarry for hunters in the southern regions where they winter, the hunting season ends if and when hunting has reduced the population by five percent, according to official estimates.  Clearly, dropping this restriction would allow the other species to recover.

 

Which of the following, if true, most seriously undermines the argument?

 

1. Hunting limits for snow geese were imposed many years ago in response to a sharp decline in the population of snow geese.
2. It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date.

3. The number of snow geese taken by hunters each year has grown every year for several years.
4. As their population has increased, snow geese have recolonized wintering grounds that they had not used for several seasons.
5. In the snow goose’s winter habitats, the goose faces no significant natural predation.

这是怎么解释通呢？arugument 还有conclusion在问题上有差异吗？

争议题目， 不讨论， 答案或者B或者D

这个题目的问题不是在于argument或者conclusion有什么差异，而是是对B选项since的理解，

根据经验，实战遇到这个题目的，都是750+的人，那个时候，这个题目已经不重要了

楼主应该放弃这道题目，抓紧看其他的，也别着急看这个的讨论帖

因为有些人支持B但是是错误的支持，没说到点上，有些人支持D也没有理解透彻。。

看了反而干扰思路。。。
