这个回答错了吧,前面的叙述并不是无用信息
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.
根据红字的一段话,D的逻辑是,因为北极南部的冰会融化,所以这个鸟(以冰下鱼为食的)就失去了食物来源,所以才不能扩大它们的range, 这个并不是咬文嚼字的文字游戏,而是原文有暗示的
