The answer is (C)- Theory of Evolution.
The basic unit of the society is the family and family living under roof is called a home. It is not of no doubt that everything happening under that roof is a simulation of bigger economic systems. The budgeting and allocation of the supplies and demands can be patterned on a much larger scale.
In my honest opinion, I think that the Chinese government has no right to block off the rights to social media and possibly the internet. The internet is how we all connect to each other, see friends, learn about the world, basically get smarter and more aware. If the Chinese government takes away the right to the internet, the literacy rate will drastically drop, and business will slow down. China won't be considered a world super-power anymore, and American companies will dominate the industry scene instead of Chinese owned businesses. To close, if there is no social media in China, China will face the consequences.
