LZ对于地理磁场这个题一直不明白，求各位大神解答

原文
mysterious phenomenon is the ability of over-water migrants to travel on course. Birds, bees, and other species can keep track of time without any sensory cues
Line from the outside world, and such ―biological clocks‖
5 clearly contribute to their ―compass sense.‖ For example, they can use the position of the Sun or stars, along with the time of day, to find north. But compass sense alone cannot explain how birds navigate the ocean: after a flock traveling east is blown far south by a storm, it will
10 assume the proper northeasterly course to compensate. Perhaps, some scientists thought, migrants determine their geographic position on Earth by celestial navigation, almost as human navigators use stars and planets, but this would demand of the animals a fantastic map sense.
15 Researchers now know that some species have a magnetic sense, which might allow migrants to determine their geographic location by detecting variations in the strength of the Earth‘s magnetic field. (157 words)

7. It can be inferred from the passage that if the
flock of birds described in lines 8-9 were
navigating by compass sense alone, they would, after the storm, fly
(A) east (B) north (C) northwest
(D) south (E) southeast

这个第七题一直没弄明白~~

原文after a flock traveling east is blown far south by a storm, it will assume the proper northeasterly course to compensate.向东飞的鸟群被风暴吹向南方后会正确地将航向调整至东北方向以弥补由风暴造成的方向上的误差，题目问如果仅靠compass sense会如何，想想看，如果你仅有方向感，不靠天体定位，不靠磁场定位（这些感觉可以帮助定位调整航向），是不是纵使你被吹离了既定航向，你还是愣头愣脑的往东飞？

楼上正解，如果没有磁场定位就不会调整误差，当然继续往东飞了~

其实这题很有趣，你可以画个XY坐标在纸上然后想象一下那个情况的。。我记得是NorthWest

说错了southeast

我总是选成这个答案，是E对吧。。这是错的。。

其实我觉得这题就是取反。。

有east, south的字眼， 取反一下就是west, north。。之前我是画XY轴找出来的，现在我忘了怎么做出来了。。
