Hi there,
1. Its C. because it shows that it is a lot of work to take care of a puppy but it does, bring Joy to the family. Its not A. because it does not talk about the puppy chewing on everything in the house. Its not B. because it does not talk about the father being allergic to cats, and its the sentence it does not talk about have a puppy instead of a cat, Its not D. because it does not even talk about anyone begging for a puppy.
2. For the second question it can not be A because there is a , in the middle of brown and paper. Its not D because it has a ; in the middle of Friend and star. um... I don't know about B and C but, the best answer would have to be C.
Hope this helped! Good Luck! :)
