1. 本句属于 A, B and C 三者并列，只需在最后两者之间加 and 即可——may prescribe..., sound... and distort。

2. than the facts warrant 是比较分句，warrant 为比较分句的谓语动词，因其主语 facts 为复数，故动词 warrant 用原形。

又如：

You are reading into the situation more than the facts warrant. 你对形势的估计比实际情况夸大了。

I think you are reading into the situation more than the facts warrant. 我认为你对局势所作的解释超越了事实的根据。
