Thank u so much for all your helps~

Here is my another question :"The argument over tax cuts should be seen for what it is, a fiscal culture war waged along ideological lines the forst shot of which was fired by Roger Douglas in 1984." I am supposing to pick put all the finite and N-F clauses

These are the answers I worked out, would you please check them for me?

for what it is     complement clause (verb) modifying seen

waged along ideological lines the first shot of which was fired by Roger Douglas in 1984     relative clause

waged along ideological lines     reduced relative N-FC??

the first shot of which was fired by Roger Douglas in 1984     reduced relative N-FC??

of which was fired by Roger Douglas in 1984     complement clause (noun)
