Question

What is the function of the noun phrase the last slice of pizza in this sentence?

I gave the last slice of pizza to my best friend.

predicate nominative

subject

direct object

appositive

Answer 1

direct object

Answer 2

It would be the direct object.

Typically in Latin, the d.o. is between the subject and the verb. Of course, in this case it applies in English as well.

The only reason i know it's the d.o. is because in Latin we have to know this stuff lol.
Sorry for that useless info^
