Identify the direct and indirect object in the following sentences using D.O. for direct object and I.D. for indirect objects.

1. Mr. Brown asked the principal several questions.
2. Our neighbor told us stories about her life in china.
3. The assistant handed the plumber a wrench and a pail.
4. They always send us pears and apples for the holidays.
5. Our teacher gave John and me a special assignment.
6. He made his mother a solemn promise.
7. Everyone boarded the bus for the picnic ground.
8. Please pass the carrots.
9. He told my friend and me a funny joke.
10. We stored the old pots and pans in a labeled carton.

if the predicate contains two nouns, usually one will be a direct object, and other the indirect object.

The indirect one answers the question: to whom? or for whom?

so, what are your choices? Not all of the sentences contain both objects.
