Q

An old woman has lived in one-story house before. Her body is very short. Afterwards, she moves into a big building and lives in the ninth story. However, when she comes back home each time, she always takes an elevator to the sixth story and gets off, then she walks to the ninth story. Why?
有位老妇人，从前住平房，并且个子非常矮，后来她搬进了一个很高的楼里，住在第9层，但是她每次回家总是乘电梯到第6层就下来，然后走到第9层。为什么？

A

Because she was too short to press the ninth button.
她太矮了不能按到第9层的按钮。

点睛一笔

一般情况下，电梯内的按钮高度是按楼层顺序排列的，也就是说1层在最下面，往上是2层、3层。题目中已经描述了这位老妇人的个子非常矮，所以她只能按到6层的高度。
