The correct answer is B: Immigration was based on the national origins quota system. The National Origins Act was a United States federal law that set the amount of immigrants from certain countries that were allowed to enter the U.S. Admission to the U.S was determined by ethnic identity and national origin. It reduced the number of southern and eastern Europeans and excluded Asians entering the country.
The Dutch East India Company was the first European that challenged the Portuguese domination of Asian trade. Different from Spanish and Portuguese traders, the Dutch expeditions were not controlled by the government, they had full sovereign powers. Because of that they had an enormous amount of power, they set up colonies and trading posts around the world, they captured Malacca from the Portuguese rule and opened trade with China.
