想问问这两句有什么不同？

At an orientation meeting, the travelers were told that a visa, a landing card, and evidence of inoculation against typhoid fever would be needed by each of them.

1. a visa, a landing card, and evidence of inoculation against typhoid fever would be needed by each of them
   
2. they would each need a visa, a landing card, and evidence of inoculation against typhoid fever
   我选了A，但是答案是B，我想知道，这两个句子意思几乎一样，到底怎么区分？我读起来反而觉得A顺一点！

我的问题是：有“they would each need 。。。”这种说法吗？
