试着解释一下,

A, 5%的规定是在若干年前基于SG大量减少的情况下制定的,也就是说和现在情况不同,应该被drop,间接支持.

B, 在过去的很多年里,打猎季节通常都结束的比预计的早,也就是说5%的减少没有达到,也可以联想是猎人没什么兴趣打猎,总之是根本达不到restriction的5%, 所以, drop这个restriction没有实际意义,从而削弱.

C, 支持. 每年都增多,如果5%不变,就是因为SG的量大了. 至多是个支持.

D, 无关.

E. 无关,注意说的是natural predation, hunting不是natural predation.

B只说了结束的比预计的早,别的可没说呀.不能连想啊.

D不是无关项.

梦不落

定出来大家看看选什么啊。个人觉得也就B能好些。

不同意选B,B的意思是说，因为有了这个规定，所以很多年打猎结束的日子都比原计划来得早。这个根本起不到削弱的作用。

请高人指点。

I support B but with another reason.

Since the time of close of the hurting season is getting earlier and according to offical estimate hunting will be close when  the population reduced by five percent ,I think that means the preiod of population reduced by five precent is getting shorter.What does it mean?That means totall amount of population of bird is not that big ,so the period of five precent reduction has been shorter.If the popluation is not big,whether this restriction is necessary?No.

对的。提早结束可能是（1）因为HUNTER没兴趣，也可能是（2）一天之内就把5% 打光了。呵呵。。

看了这么多唯一一个觉得reasonable的解释...但是这种想法太绕，恐怕目前的能力难以想到。我再想会不会在其他方面还能有更好的解题方法
