Question

When the servers arrived, Zach gave them the information on today's specials
I am not sure of the direct object of the main clause

I think it is "information" and the indirest object is the specials

Answer 1

You're right about the direct object.

The indirect object answers "to whom" after the verb. Therefore, the indirect object is "them."

The object of the preposition "on" is "specials."
