Three basic ways may be described as the market system, the administered system, and the traditional system. 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, _ goods such as automobiles, shoes, 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. An alternative to the market system is administrative control by some agency over all transactions. This agency will issue 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. 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. An inactive society may result. Question: Which of the following is not mentioned by the author as a criterion for determining a person's position in a traditional society? Options: A: Family background B: Age C: Religious beliefs. D: Custom

The rules ban advertisements for unhealthy foods in schools. The ad ban includes sugary drinks that account for more than 90% of unhealthy ads. An ad for Coca-Cola, for example, will be removed from a scoreboard at a high school football game. However, ads for Diet Coke and Dasani water, owned by the same company, are allowed to display . The new rules are part of the First Lady's "Let's Move" campaign to fight childhood obesity . Her goal is to get kids to eat healthier food. The marketing limits came after new USDA regulations that put a limit on the calorie, fat and sugar in most school food items. "The idea is simple -- our classrooms should be healthy places," the First Lady Michelle Obama said. "Because when parents are working hard to teach their kids healthy habits at home, their work shouldn't be destroyed by unhealthy messages in schools." However, the healthier food rules are criticized by people who think the government should not control what kids eat and by some students who don't like the healthier foods. It is reported that food companies spend $149 million a year on marketing foods to kids, and many big companies are supporting the new rules. Coca-Cola and PepsiCo have started to advertise healthier products. For schools, junk food ads like the Coca-Cola scoreboard will be taken down. "The new limits ensure that schools remain safe places where kids can learn and eat healthy food," Agriculture Secretary Tom Vilsak said. The rules will help guide schools on ways to create standards for foods and physical activities. They will require parents and the community to be involved in the campaign. Question: Which of the following is TRUE according to the text? Options: A: All advertisements for Coca-Cola in schools will be removed. B: All people approve of banning advertisements for unhealthy food. C: Schools play an important role in forming children's healthy habits. D: The new limits will have a negative effect on all food companies.

Q: Read the article and select the best answer. Article: Most people are aware of what the adoption process is because it has become rather common in our society. Adoption is where a child is legally placed with guardians or parents (or perhaps a single parent) other than the birth mother or father. Once an adoption is finalized, all parental rights are turned over to the adoptive parents and there is no legal difference between adoptive parents and natural birth parents. There are generally two types of adoption, which are closed adoption and open adoption. When an adopted person has access to his or her adoption file and original records, it is referred to as an open adoption. The term is also used to describe any contact that may be between the adoptive family, the birth parents, and the adopted child. The level of openness can change greatly in such contact depending on each individual relationship. There can be indirect contact between the natural birth parents and the child through the form of letters and photographs, or there can be actual physical contact. A semi-open adoption is where the birth parents may have contact with the adoptive parents before the birth of the child, either once or several times. After the birth there is no more contact. A semi-open adoption may remain as it is or it can become either open or closed. A closed adoption is where only the medical and historical information about the biological parents is given to the adoptive family. Typically, the birth and adoptive parents do not know each other's identities. The record of the birth parents is kept sealed . A closed adoption is usually only effective in the adoption of babies. The adoption of an older child who already knows his or her birth parents cannot be kept closed. Question: Which of the following statements is TRUE about the closed adoption? Options: A: The birth parents may have indirect contact with the adoptive parents. B: The biological parents may often go to see their birth child. C: No information about the biological parents is given to the adoptive parents. D: Generally speaking, the adoptive parents do not know the birth parents' identities.
