A;B
They asked the government to make ______ clear to the public _____ they did was right.
A. it; that what B.it; what
选A what they did was right是从句中真正的宾语。这里是由that引导的宾语从句。that在后面宾语比较短时是可以省略的。但是这里由于真正的宾语是what they did was right,宾语过长,所以that最好不要省略。
It is not clear ____we find the way to that house.
A. that how B. how
选A 这里是由that 引导的主语从句,that在主语比较短时是可以省略的。但是这里由于真正的主语是how we find the way to that house,主语过长,所以that最好不要省略。
第二个貌似是强调句型it is ...that...
