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)

"The argument over tax cuts should be seen [1] for what it is : a fiscal culture war [2] waged along ideological lines [3]the first shot of which was fired by Roger Douglas in 1984."

[2] : (a war) <that has been> waged along ... in 1984. :-> reduced non-finite clause

[3] : the first shot of which (=a war) was fired by ...in 1984. :-> relative clause [adjectival]

As for [1] (=for what it is), it is tough to parse. It can be somehow taken as a manner adverbial phrase modifying the verb 'see', but it can be taken also as the complement of "the argument". But anyway, it may belong to complement clauses according to your classification.
