For muscular endurance Dynamic Repetition is always advised, where you repeat a particular test more than 12 repetition, where as for strength it is expected to do repetition one to three times. 
 
        
             
        
        
        
The answer for this question would be B) Say that you are not ready and hope that he or she will respect that because well first lets do process of elimination.
Not A) because sexual intercourse can be private so no one has to know or it can be public if u share it with others by telling them or posting it online, not C) because well this could be a good choice but if u want to tell your partner to not pressure u, than just tell them and they could stop or find someone else who respects u, not D) because that's a bit dramatic and overboard, in a relationship its not all about sex, that's why people be virgins- people who don't have sex or lose their virginity, so u can still be in the relationship just without the intercourse, so its B) because its true and is more gentle.

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.
