How did geography shape civilizations in ancient india and china?
a) they built cities away from areas prone to flooding and dangerous weather
b) they grew along rivers and other bodies of water
c) they emerged where mountains and other natural barriers offered protection
d) they constructed towns and cities well-established trade routes

i believe the correct answer is b.

biological/genetic factors means they were born or predisposed to have something. nothing can really change it, and you can't really do much to "fix" it. it isn't something learned

these are the biological factors:

adrian is relatively tall and he is on the basketball team

(adrian can't ever stop being tall or force himself to be tall. likely one or both of his parents are tall as well and they passed on the tall gene. he probably does basketball because he is tall)

the rest are environmental/cultural factors. these are things that are taught to us. for example, cynthia wasn't born saving pocket money, her family most likely taught her this (environmental factor)

hope this !
