Answer:
Explanation:
I think you want to know about her new job.
It's not an infinitive. to know is an infinitive. About her new job does not begin with to.
It's not an appositive. An appositive is something like Kris, the boy on the right, is my friend. Kris and boy are the same thing separated by commas.
