What are the duties of a social prefect in a secondary school ​

(sorry for a late answer but hopefully this helps)

Explanation:

School prefects can serve as a liaison between students and teachers, helping both get their sides heard and understood, and speaking on behalf of students who are too shy, frightened or cynical to speak for themselves.

giant impact theory - the moon was formed from the collision between earth and another mars-sized body.

colliding planetesimals hypothesis - the moon was formed from the same cloud of material as earth.

capture hypothesis - the moon was locked into orbit by earths gravity as it was passing by it.

accretion hypothesis - the moon was formed from collisions and combining of planetesimals.

i think this is right, if not and you know better let me know.
