There was _____ much static on the radio that we couldn’t hear the broadcast.
如果是考试或学生做练习，显然宜选 so，即网友说的构成 so…that句式：
There was so much static on the radio that we couldn’t hear the broadcast.
英语一般不用 too…that 这样的搭配；用 too 的相关搭配是 too...(for sb/sth) to：
There was too much static on the radio for us to hear the broadcast.
There was too much snow for us to go walking. 雪太厚，我们无法出去散步。
There was too much data for the computer to process. 这台计算机要处理的数据太多了。
