I actually did this for an assignment awhile back. First of all I would use “following through WITH a promise” unless the assignment said on. I can’t remember exactly what I said but I think it was something about watering a plant bc I mean if you don’t water a plant constantly it will die and if you constantly break promises whatever relationship you have will also break or die. I got a good grade so I hope this helps if you decide to use it :)

The difference is that each particle which makes up the medium through which a longitudinal wave propagates oscillates along the axis of propagation. ... Matter in the medium is periodically displaced by a sound wave, and thus oscillates.
