题目：
Guillemots are birds of Arctic regions. They feed on fish that gather beneath thin sheets of floating ice, and they nest on nearby land. Guillemots need 80 consecutive snow-free days in a year to raise their chicks, so until average temperatures in the Arctic began to rise recently, the guillemots’ range was limited to the southernmost Arctic coast. Therefore, if the warming continues, the guillemots’ range will probably be enlarged by being extended northward along the coast.
Which of the following, if true, most seriously weakens the argument?
Which of the following, if true, most seriously weakens the argument?
选项:
A、Even if the warming trend continues, there will still be years in which guillemot chicks are killed by an unusually early snow.
B、If the Arctic warming continues, guillemots’ current predators are likely to succeed in extending their own range farther north.
C、Guillemots nest in coastal areas, where temperatures are generally higher than in inland areas.
D、If the Arctic warming continues, much of the thin ice in the southern Arctic will disappear.
E、The fish that guillemots eat are currently preyed on by a wider variety of predators in the southernmost Arctic regions than they are farther north.
答案:
D

B、D二选一时，B有跳跃推断的“马后炮”的嫌疑，但大方向上逻辑并无绝对错误，被我留下了；而D选项我关注的重点是状语部分，特定说的是南边的冰会融化，那南边没鱼吃了，那些鸟不得就只能往北边去了，所以应该是支持原文，而不是削弱，立马被我排除了。但这种情况下，抱着只需要知道how，不需要知道why的思维，即使B可能不是最优选项，但我还是义无反顾选了B。请老师答疑，为啥我盯着答案看了很久依然不明白
