Answer:
Schools that have a uniform policy report lower rates of fighting and higher participation in after-school activities.
Step-by-step explanation:
Firstly, none of the others show pride. Secondly, fighting less indicates that a student is taking pride in themselves such as their health, their school relationships and their reputation at school. Higher participation in activities, especially since they are outside mandatory school time, indicates that a student is taking pride in their future career (activities can help a personal statement), their involvement in school (especially if this is an activity representing the school) and you could argue that the more time a student spends at school I.e the more effort they put in, indicates a higher amount of school pride.
