1 C. The growing middle class demanded more democracy, so voting rights gradually expanded.
During the industrial revolution, many of the middle class was taken advantages of by business owners and given unfair salary and overly long work hours.
The growing middle class was seeking to change that situation, so the need to expanded voting rights started to increase. Until eventually , government start to pay attention and regulate how companies can give salaries and maximum working hours for the workers.
2 B. A classless society in which wealth and power were equally shared
In the utopian society built by Marx, social class shall not exist and people could live on equal status.
When this theory was implemented in soviet union, the idea failed completely because the communists disregard a couple of things.
For example, when wealth and power were equally shared without putting consideration on talents and working hours, there are very few people who are willing to work hours to be more productive. This cause a massive poverty on countries that were run on communist system and they eventualyl started to fail or choose to combine both communist and capitalist ideology into a mixed system.
