Which name for the period between world war 2 and the present best emphasize the social changes that took place a the cold war b the post war era c the civil rights era d the mid centuary

The mid century is the design movement for interior things and such, so that's not it.

The cold war was a completely separate war, so that's not it, either.

The post war era is a time after a war, so it could be mourning, celebration, and rebuilding.

This leaves the civil rights era, which is the correct answer. After all the big wars, Americans started fighting for what they deserved inside their home.

1) union forces launched a surprise attack.

2) more confederate troops arrived by train.

3) union forces retreated.

i think it is true i hope this is
