假如，我们对此问题有这么一个回答， 我们就不难看出， ”how full” 问题是关于搭载率：

Q: How full does an intercity train need to be in order to be more efficient than having each individual drive a car for the same journey?

A: I think, 60% is a minimum.

在相同旅程中，为了使其比各自单独驾车效率更高，城际火车要有怎样的搭载率呢？

我认为，60%是最小的（搭载率)。

为了使其比在相同旅程中各自单独驾车效率更高，城际火车要搭载多少人才合适？

为使在相同旅途中，比个人驾车效率更高，城际火车的最多载人应该是多少呢？
