求助：The issue of Whether\what\how …原题……is a hot and important topic for us nowada

在用这句话开头中，遇到不同的题感觉会用不好，比如下面的这个：

１５９：The twentieth century saw great change. In your opinion, what is one change that should be remembered about the twentieth century? Use specific reasons and detail to explain your choice.

  我用这个开头号是这样写的，可是感觉不通，请大家指教一下，这个开头结构在把原题放进去的时候，应该怎么来安排语言，是一个什么样的结构？

下面是我１５９开头．请指教：

The issue of what is one change that should be remembered about the twentieth century is a hot and important topic nowadays.

感谢
