Which of the following leaders tried to reform the Soviet Union to expand freedoms of the press, religion, and speech within the country?

"the attempts of the proletariat to rise above this abasement"

economic advantages.

first of all, the south suffered a lot more damage then the north.

second of all, because the south has better weather, they usually stuck to farming instead of building up industries. the north, on the other hand, built up their industries much quicker and had a lot more factories then the south. also, more people lived in the north then in the south, allowing the north to quickly build up their armies. 

hope this
