The huge amount of people in China that migrating internally towards the cities is because of two main reasons:
1. The cities in China have developed immensely and offer lots of opportunities; the Chinese cities have developed significantly from all aspects, they offer lots of opportunities, bigger wages, better life, and the chance for prosper.
2. The rural areas of China had not experienced any significant development and mostly stagnate; the rural areas of China have remained mostly poor, the opportunities are limited mostly to working in agriculture, they have stagnated in time unlike the urban areas of the country, the income is very low, and prospering into this environment is extremely difficult and usually limited to only certain individuals.

Let's look at all the claims:
.
A. He was a professor of mathematics at Cambridge University.
- yes, this it true! (his position was called Lucasian Professor of Mathematics)
B. In his book, Mathematical Principles of Natural Philosophy, Newton laid
out three laws of motion that are still the basis for studying how
things move.
- this is correct! those laws are known as Newton's laws of motion.
C.As Newton went on developing his ideas
in astronomy, mathematics, and physics, he became very unpopular and was
often ridiculed for his works.
-this is a complicated question: Newton's work was accepted, but he had a difficult personality, which made him rather unpopular- so I would mark the whole statement as also true.
