Answer to what? I’ll try my best to assist you on whatever you need help with.
Answer:
The health of some people might improve
Explanation:
What I mean is that if the school previously didn't have a specific health program some students might not be aware of certain things which damage their body.
If they implement the health program the students will have a wider array of knowledge about things that might damage their body. It also will improve the average health of students since they will start ( at least some of them) to pay more attention to their health and eat less junk food and will start doing sports etc.
Well that might not be completely correct answer so I advise you to compare with different answers.
