Question

Give Ben and his cousins a snack before bedtime which word in the sentence is an indirect object

Answer 1

Snack, because it is an object but not specified like ben, cousins (because people) or bedtime

Answer 2

So, yes it would be "snack". An indirect object answers the questions To or for whom? or To or For what? after an action verb. A direct object is a noun or a pronoun that receives the action of the verb.

Ex. Give Ben and his cousins a snack before bed. Give who a snack before bed? Ben and his cousins. This is a direct object example.
