A Pollet的意思|示意

So part of the effect Dr Pollet has discovered might be caused by the fact that, obviously, a man is older when he takes a second or subsequent wife than when he marries for the first time.

因此波兰特教授的研究结果很有可能部分因为另外一个很明显的原因，即当一个男人娶第二任或者其他更多任的妻子时，他的年龄一定比第一次娶妻时大。

Dr Pollet and his colleagues therefore turned to Rwanda, and used data gathered in a census of that country taken in 2002.

因此波洛特教授和他的同事们在卢旺达开展了这项实验，并使用了2002年的人口普查数据。
