Research Papers / Need to research evolution of govt, business, and familes from 1877 to 1945 [2]

1000-1500 words on the evolution of government, business, and families from 1877 to 1945. Was given these 3 sub topics - Which of the 3 had most say in development of culture, empire, and politics / interaction of the 3 positive, negative, or neutral / lenses of class, gender, and race provide any insight to discrepancies between groups

I am kind of struggling on this one if anyone has any help resources to help me out. Most of all if anyone has any insight on the 3rd sub topic. Really struggling with that one.

Thanks!
