10. The plan of the class, to go to the museum, was approved by their adviser.

I can identify the infinitives, but to classify them, am not pretty sure if I can.

Answer 1

In sentences 1 and 2, the main verbs are linking verbs (was, is). Since the infinitives in those sentences come after those verbs and are "re-naming" the subjects, they must be predicate nouns.
