Question

the good dog
1 today i met a new patient. he was a retriever and shepherd mix with reddish fur and big brown eyes. he reminded me of my rex. ive met a lot of great pets through my practice, and i try to help them. my first dog, rex, is the reason i do what i do.
2 when i was twelve, i was fed up with school. i was tired of getting in trouble. i remember one day my mother went to speak to my teachers. when she came home, she had this look on her face, and i could tell she had been crying.
how does taking care of rex help john with his problems at school?
taking care of rex shows john how to get along with his teachers.
taking care of rex gets john to solve problems in new ways.
taking care of rex helps john become more responsible.
taking care of rex teaches john how to be a leader.

Explanation:

To determine the answer, we analyze the context. John was having school problems (getting in trouble, mother crying after teacher meeting). Taking care of a pet like Rex typically fosters responsibility. The other options: getting along with teachers isn't directly linked to pet care, solving problems in new ways isn't implied, and being a leader isn't related to pet care for school issues. So the most logical is that caring for Rex builds responsibility to help with school problems.

Answer:

Taking care of Rex helps John become more responsible.
