I'm doing a take home exam, and this is a question :
The professor watched his student writing their exam.
This sentence demonstrate
a) a transitive pattern + object complement
b) a transitive pattern + indirect object
c) a transitive pattern with no other complement.
As i'm not sure as what is acting the grunf phrase here. Is it a object complement, as it does complement the object (student).
Thanks all for your hepl!
