The rebirth of knowledge in the Renaissance changed the way that artists created their work and the way people saw the world. One of the earliest examples of this was the use of perspective in oil paintings. This was a way of showing space, depth, and distance in the picture. It made the painting look more realistic. The Renaissance began in Italy, the birthplace of the Roman Empire. It is nearly impossible to identify all of the reasons why the Renaissance began in Italy, but three important causes were money, disease, and historic architecture.
I believe the answer is: D. There are three economic classes: the rich, the poor, and the middle class.
The separation between these classes is based on their ownership of wealth&resources. The poor are those who barely have enough resources to keep living,
The middle class are those who can comfortably fulfil their basic needs while having a little bit of surplus that they can put into saving , while the Rich are those who had abundance of wealth & resources, to the point where they would not able to spend it in their lifetime.
What is the question here??
