Answer:
a. Lack of food, supplies and conflict with Native Americans
Explanation:
The major challenges facing early settlements in the New World were the unavailability of food because it was a new place for it and they obtained their food due to hunting of animals which is a hard way. The other problem the people faced was the conflict with the Native Americans which attack on there settlers because they thought that these people were here to captured their lands.
The second Klan arose in 1920 with a broader agenda because anti-black racism was not an adequate motivator in the North, where few African Americans lived at the time, it targeted Catholics, Jews, and in the West, Japanese and Mexican Americans.
The archeological rests discovered at Caral (Supe Coastal Region, North-Central Peru) have been dated as the oldest ever found in America, from 5,000 years ago. These pertain to the Norte Chico or Cara-Supe civilization, a complex pre-Columbian society which developed between the fourth and second millenials BC, contemporary to the more widely known civilization in Ancient Egypt. These discoveries have shifted the focus of research from the Andean Regions of Peru to coastal regions.
It is surprising the small worlwide reknown reached by this complex and very ancient society if compared to others such as Egypt.
Answer: C. Trade regulation
Explanation: Adam Smith is considered the father of a modern liberal economy. The modern economy pulls its roots from the "Wealth of Nation," the capital work of this economic genius. According to Smith, economic relations should be free from any government oversight, and give full freedom to entrepreneurs. In such conditions of free market, the market itself is governed by the law of capital, i.e. invisible hand. In doing so, the division of labor should be done as the key to the success of the market economy, the epochs of a narrow specialization of jobs, and thus productivity increases and the economic systems themselves are far more efficient.
