What were the economic, political, social, and scientific changes that brought
the world to the brink of a second world war? +

I'm not sure if this is what you are asking, but in Europe;

Explanation:

A lot of the causes of WWII were rooted in WWI and the peace process that followed.

Economic: The German economy was destroyed by end of WWI. Germany also went through many economic bad times after 1918.

When the Nazis came to power they began to make deals outside of the normal Economic System. This include Barter, the forced confiscation of assets of some companies operating in Germany, and the rejection of the terms of the Treaty of Versailles.

These and a massive military re-armament rebuilt the German Economy while the rest of Europe sat in economic doldrums.

Politically: Bad economic times and fear of another terrible war made European countries at the mercy of a political bully and opportunist like Hitler.

Socially: The losses of millions of men in WWI profoundly affected the survivors. Women had been given important home front roles during the War and then had them taken away when the men returned. Economic uncertainty and the military after shocks in Eastern Europe, Spain, and the middle east all created post war uncertainty. The rise of Communism and Fascism played on fears for the future. People desperately wanted security.

The result of this was the rise of powerful forces that created WWII.

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 !
