Question

To what degree, if any, did WWI solve the problems that caused it?

Answer 1

WWI helped in "Medical Advances". As many soldiers and individuals were injured during the war, some educated individuals [ Doctors ] tried and worked hard for preparing medicines for their communities. It was an advantage for whole world forever, like still we are using same antidots/antibiotic for certain diseases. It solved up to an extent that every country saved their a lot of soldiers by their medicines.

There was a lot of hazardous diseases during the WWI [ created by humans 'cause of roughness, lack of cleanness due to the War ], which can lead to death but WWI solved it, in the form of some educated people

Hope this helps!
