[Q]: Article: Labor force is defined as being the total number of people who are available to work and earn income. This definition includes everyone who is employed or seeking paid employment, so it includes employers and the self-employed. Labor is one of the country's resources which can be combined with other resources to produce the goods and services wanted by the community. Although the size of the workforce depends a great deal on the size of the total population, there are several other influences which also affect it. The age distribution of the total population has a very marked effect on the available workforce. If the population has a high proportion of very young people or of those too old to work, then the available workforce would be lower than if there were a balanced spread age distribution. If the population naturally grows rapidly, the number of births greatly exceeds the number of deaths then as a total population increases proportion of the workforce declines. Sometimes a population is described as aging which means that the birth rate is either falling or growing very slowly, and as people retire from the workforce there are insufficient numbers of young people entering it to replace those who are leaving it. In that situation the population is top-heavy with older people. So the percentage of the population in the workforce declines when there is either a rapid increase in births or a falling birth rate. The age distribution of the population has several important effects on the economy. If the population is aging and there is an increase in the number of people retiring without a corresponding increase in the number entering the workforce, this raises the problem of the ability of the economy to provide a reasonable level of social services to the retired group. If the aged are to be cared for in special homes, finance must be available for that purpose. If the size of the workforce is small to the total population, then the government tax revenue is ly low and either the government has less money available to it or workforce members have to be taxed more heavily.

[Q]: Article: For the first time in modem history, less than half of theprefix = st1 /U.S.adult population now reads literature, according to a recent survey. Reading at Risk: A Survey of Literary Reading inAmericapresents a detailed review of the decline of reading's role in the nation's culture. Readingat Risk is a survey of national fashion in adult literary reading. The data source for Reading at Risk is as reliable and objective as any such survey can be. The key results of the survey are presented in the "Summary", but the report can be further explained as: literary reading in Americais not only declining rapidly among all groups, but the rate of decline has been speeded up, especially among the young.Readingat Risk merely shows a great _ that most Americans have already noted - our society's great turn to electronic media for entertainment and information. Reading a book requires a degree of active attention and devotion. Indeed, reading itself is a progressive skill that depends on years of education and practice. On the contrary, most electronic media such as television, recordings, and radio make fewer demands on their audiences, and indeed often require no more than passive participation. While oral culture has a rich reality and electronic media offer the considerable advantages of variety, print culture affords irreplaceable forms of focused attention and thought that make various communications and views possible. The decline in reading, therefore, equals a larger retreat from participation in public and cultural life. What is to be done? There is surely no single solution to the present problem, just as there is no single cause. The important thing now is to understand thatAmericacan no longer take active and devoted reading for granted. Readingis not a timeless, common ability. As more Americans lose this ability, our nation becomes less informed, active, and independent minded. These are not qualities that a free, inventive, or productive society can afford to lose.

[A]: The main purpose of the survey is to _ .

[Q]: Article: On an elementary school playground, hundreds of children run and jump, smiling and laughing as they play. Watching sea otters playing in their own environment is like watching children at play. Sea otters, which are presently on the endangered species list, are experiencing an increase in population. Groups of sea otters live on the shores of the North Pacific Ocean. They are seldom found far from land but almost spend their entire lives at sea. The otter has been known to dive as deep as 180 feet and stay underwater as long as minutes. Each day the sea otter eats as much as one-fifth of its body weight in fish or shellfish. Not only are sea otters playful, they are also amazingly resourceful. Their favorite food, abalone , is protected by a thick shell that sea otters are unable to break with their teeth. Sea otters use stones from the ocean floor and break the abalone open on their bellies as they move slowly across the surface of the water on their backs, a behavior that makes them one of only a few animals on Earth, including human beings, to use tools! Their intelligence is also displayed while sleeping. In order not to move into dangerous waters, sea otters actually cover themselves with plants on the sea, which keep them in place before falling asleep. Because sea otters have a special means of keeping insulated , they can keep their body heat in their cold environment. They have unbelievably fine fur that traps tiny bubbles, and that keeps them comfortable when warmed by body heat. However, their fur loses this insulating quality if it becomes dirty. Sea otters have faced dangers from hunters in the past and from oil spills more recently. Fortunately, due to a 1911 agreement and to rescue and habitat protection efforts, the sea otter population has nearly recovered.
