Answer:
1- The correct answer is B. For most settlers, the MAIN attraction of the western territories of the United States in the early-1800s was that plentiful, cheap, and fertile land was there.
2- The correct answer is C. Based on this excerpt from the Dawes Severalty Act, United States domestic policy toward Native Americans in the late 1800s made an attempt to force Native American Indians to give up their traditional cultures.
3- The correct answer is A. This excerpt is often referred to as the "equal protection clause" of the Constitution and is directly tied to the Constitutional principle of judicial review.
Step-by-step explanation:
1- The march of settlers to the West had a lot to do with the discovery of wealth, as evidenced by the famous California Gold Rush, or the need for spaces for livestock or agriculture. The speed of colonization is also due to the expansion of the railroad.
2- The Dawes Act of 1887 was a US law passed by Congress in 1887, deciding to register the lands of Indian tribes and divide them into individual plots. Indians who agreee to live separately from a tribe on a registered site could receive US citizenship. The main purpose of the law was to improve the living conditions of Native Americans, and their assimilation.
3- The Fourteenth Amendment states that states may not violate the precepts of the Equal Protection Clause. In that sense, the Supreme Court may dictate the unconstitutionality of the laws that the states sanction violating this clause, through the judicial review.
