Answer:
1. "I dropped my cookie on the ground."
2."Mr.Peanutbutter was ready for bed"
3. First person
4. Confusion
5.His life experiences make him what he is, and that will come out in his writing****
Explanation:
1. It could be "My cookie fell on the ground" or "I dropped my cookie on the ground" but I would most likely go with "I dropped my cookie on the ground." Because I would say that more often.
2. You chose "having run around with the dogs for an hour" which is a sentence fragment. "Bed sounded like a great idea" is technically right but I think they want you to put the other option.
3. First person because he keeps saying I - which would not be said in either of the Third persons
4.Confusion because he doesn't sound angry or certain he says," It's not easy to know what is true for you or me"
5. Its the most logical answer.
