N what ways does South Africa's history of Apartheid remind you of our own history of Segregation and Racism in the U.S.A.?
Aloiza [94]

Answer:

Apartheid was an official policy of racial segregation in South Africa from 1948 to 1994. Although racial segregation and discrimination arose earlier, after the 1948 general election, people were divided into classes by law: black, white, colored, and Asian. People of different skin colors who had lived together so far were separated, and two infrastructures were set up in the country, one for whites and the other for blacks.

This situation was clearly similar to that of the racial segregation that took place in the southern United States from the end of the Civil War until the 1960s, through which the Democratic governments of the southern states segregated African-American populations from their territories, relegating them to a citizenship of inferior conditions, with worse public services and a general lack of rights compared to those of whites.

Las Vegas, Nevada, has seen a great increase in the demand for water since it is one of the fastest growing regions in the U.S.
klasskru [66]

Answer:

The statement is true. Las Vegas, Nevada, has seen a great increase in the demand for water since it is one of the fastest growing regions in the U.S.

Explanation:

Las Vegas is the most populous and most densely populated city in the state of Nevada. It is located in the south of the state, in Clark County.

According to the 2010 national census, the city itself has 583,756 inhabitants, and its metropolitan region has about 1.9 million inhabitants. It is the 30th most populous city in the United States and is considered to be the fastest growing city in all of North America.

Population growth was especially marked in the 1990s, when the population went from a little over 200,000 people to more than 500,000. This brought a consequent lack of resources due to the desert location of the city, which was solved only with investment in infrastructure by the state government.
