Compare and contrast the hominids Australopithecus and homo erectus.
Because in order to do anything that's fun, like hanging out with friends,
learning math, going to the beach, reading a book, playing with a dog,
going for a bike ride, going to school, and like a whole bunch of other
things like those, you like have to be living, or else like none of it works.
If you can exercise without fatigue you are fit and healthy :)
I would think b! Hope that helps
