D.      they would each need a visa, a landing card, and evidence of inoculation against typhoid fever

E.       they would need visas, landing cards, and evidence of inoculation against typhoid fever for each of them.

正确答案为：D，

为什么E不行？

不选A是因为主动优先，还是因为其他原因？请高手指点。

我也选的A，不明白有什么不妥？难道是主动优先？

they would each need，好像在哪里看到过each的这种用法，是否有高手详细说明一下，并举几个例子？其他SC题目中是否有类似的题目？

谢谢！
