When was genocide officially labeled a crime? in 1941 when Lemkin moved to the United States from Poland
in 1943 when Lemkin used genocide in a quote
in 1945 shortly after the end of WWII
in 1948 as defined by the UN

after ww2 given what happened in nanking and the holocaust

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 !
