各位老师们，请问:
Whether we can have cleandrinking water lies in what effective measures will be taken by thegovernment about water pollution.
句中的what成分怎么样剖析？what是可以做限定词修饰名词吗？和what time is it？类似，有没有关的语法点?
Whether we can have clean drinking water lies in what effective measures will be taken by the government about water pollution.
【翻译】大家能否拥有清洗的饮用水取决于政府将采取哪种有效手段来解决水污染问题。
what effective measures will be taken by the government about water pollution. ——这是 what 作为限定词引导的名词性从句，作 in 的宾语。
其中，what effective measures 跟 what time 都是一样的结构，what 限定用途而且带有疑问含义，意为“哪种；什么的”。
我举一个类似的例子：How much you know depends on what books you read. 你常识的多少在于你读哪种书。
