(A)

Brian really wanted a new bike like his friends had. His bike was old and was too small for him. A new bike would cost $110. But all he had was $33. Where could he get the rest of the money?

Brian did a lot of thinking, His birthday was still five months away. He couldn't wait that long. What could he do to get the money? Maybe he could clean the house for his mom.Maybe his sister would lend him the money. While he was thinking, the phone rang. Mrs.Wilson's dog had gotten out again. She asked Brian if he could find it for her. Brian was glad to help Mrs. Wilson. She was getting so old and couldn't run after the dog anymore.

After catching the dog, Brian returned it to Mrs. Wilson. She was so thankful that she gave two dollars to him. Brian thanked Mrs. Wilson, and suddenly he had an idea. He would set up a pet service. He could take care of his neighbors' pets when they were away. In his neighborhood, there were at least 12 dogs he could look after, a few cats, and even some fish.Brian would have a new bike soon.
