The correct answer to this open question is the following
I think the Industrial Revolution led to the rapid growth of cities in the northeastern states because in this region were located the big factories and fabrics that introduced mass production as their form to produce goods.
Many people from the south. who lived in the rural areas of that region, decided to move to the larger cities of the northeast precisely to get a job in the fabrics. Many immigrants came to the United States to work in factories, They came from Europe and Asia. They went to New York or Chicago, and many other cities.
Of course, the population grew and these workers, as they were poor, they had to live in poor overcrowded spaces with no ventilation at all and where disease spread quickly and easily.
The correct answer is "C".
The Partition of India of 1947 marked the beginning of the end of the British Rule over India. It consisted of the separation of the Indian subcontinent into 2 separate administrative territories. One of them being Pakistan and the other India. The separation was mainly due to religious reasons, as the Pakistani people were Muslim and the Indians practiced Hinduism.
Leading European democracies in addition to the US were challenged by crippled economies and devastated landscapes from World War I. Governments were wanting a return to more isolation and policies which favored their own countries. In the case of Germany, they were struggling to reestablish nationalism and were unable to defend themselves as a country. As a result many people in those countries turned to alternate forms of economy and government to create solid nations once again. All countries saw a rise in socialist thinking and some countries began to move toward socialist ideology. In others especially, Italy and Germany a move toward fascism took place which put nationalism at the forefront and a build up of capitalism to secure their economic place in the world.
I believe the answer is A according to my calculations.
