Answer 2

direct object

Answer 3

I- personal pronoun serving as the subject of the sentence.
ate- verb
a- article indicating number
snack- noun serving as the direct object
of- preposition starting the prepositional phrase
almonds- noun serving as object of the preposition
of almonds- prepositional phrase modifying snack
which- relative pronoun, referring to snack in the independent clause.
satisfied- verb of the adjective clause
my- pronoun indicating possession
hunger- noun, the object of the adjective clause

"which" is the only relative pronoun in the sentence. It renames "snack", the direct object.
Your questioner is probably expecting the answer "direct object."
