1 There are various ways in which individual economic units can interact with one another. Three basic ways may be described as the market system, the administered system, and the traditional system.
2 In a market system individual economic units are free to interact among each other in the marketplace. It is possible to buy commodities from other economic units or sell commodities to them. In a market, transactions may take place via barter or money exchange. In a barter economy, real goods such as automobiles, shorts, and pizzas are traded against each other. Obviously, finding somebody who wants to trade my old car in exchange for a sailboat may not always be an easy task. Hence the introduction of money as a medium of exchange eases transactions considerably. In the modern market economy, goods and services are bought or sold for money.
3 An alternative to the market system is administrative control by some agency over all transactions. This agency will issue edicts or commands as to how much of each good and service should be produced, exchanged, and consumed by each economic unit. Central planning may be one way of administering such an economy. The central plan, drawn up by the government, shows the amounts of each commodity produced by the various firms and allocated to different households for consumption. This is an example of complete planning of production consumption, and exchange for the whole economy.
4 In a traditional society, production and consumption patterns are governed by tradition; every person’s place within the economic system is fixed by parentage, religion, and custom. Transactions take place on the basis of tradition, too. People belonging to a certain group or caste may have an obligation to care for other persons, provide them with food and shelter, care for their health, and provide for their education. Clearly, in a system where every decision is made on the basis of tradition alone, progress may be difficult to achieve. A stagnant society may result.
According to the passage, ______ has the greatest degree of control in an administered system.

A. every two days.
B. every other day.
C. together with fruits.
D. in small amounts.

As a student, Du Bois was considered something of a prodigy who excelled beyond the capabilities of his white peers. He found work as a correspondent for New York newspapers, and slowly began to realize the inhibitions of social boundaries he was expected to observe every step of the way. When racism tried to take his pride and dignity, he became more determined to make sure society ’recognized his achievements.
Clearly, Du Bois showed great promise, and although he dreamt of attending Harvard, some influential members Of his community arranged for his education at Fisk University in Nashville. His experiences at Fisk changed his life, and he discovered his fate as a leader of the black struggle to free his people from oppression. At Fisk, Du Bois became acquainted with many sons and daughters of former slaves, who felt the pain of oppression and shared his sense of cultural and spiritual tradition. In the South, he saw his people being driven to a status of little difference from slavery, and saw them terrorized at the polls. He taught school during the summers in the eastern portion of Tennessee, and saw the suffering firsthand. He then resolved to dedicate his life to fighting the terrible racial oppression that held the black people down, both economically and politically.
Du Bois’s determination was rewarded with a scholarship to Harvard, where he began the first scientific sociological studies in the United States. He felt that through science, he could dispel the irrational prejudices and ignorance that prevented racial equality. He went on to create great advancements in the study of race relations, but oppression continued with segregation laws, lynching, and terror tactics on the rise. Du Bois then formed the Niagara Movement, and in 1909, was a vital part in establishing the National Association for the Advancement of Colored People. He was also the editor of the NAACP magazine The Crisis from 1910 to 1934. In this stage of his life, he encouraged direct assaults on the legal, political, and economic system, which he felt blossomed out of the exploitation of the poor and powerless black community.
He became the most important black protest leader of the first half of the 20th century. His views clashed with Booker T. Washington, who felt that the black people of America had to simply accept discrimination, and hope to eventually earn respect and equality through hard work and success. Du Bois wrote The Souls of Black Folk in 1903, criticizing Booker, claiming that his ideas would lead to a perpetuation of oppression instead of freeing the black people from it. Du Bois’s criticism lead to a branching out of the black civil rights movement, Booker% conservative followers, and a radical following of his critics.
Du Bois had established the Black .Nationalism that was the inspiration for all black empowerment throughout the civil rights movement, but had begun during the progressive era. Although the movement that germinated from his ideas may have taken on a more violent form, Web Du Bois felt strongly that every human being could shape their own destinies with determination and hard work. He inspired hope by declaring that progress would come with the success of the small struggles for a better life.
