[EX 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.

[EX Q]: Article: When Ann, a grade two student at a well-known school, was pestered by her classmates to join their group to steal from shops, she was shocked. She was a quiet, well-behaved girl and she did not understand why the girls had approached her. They showed her some of the things they had stolen and said that shop theft was great fun and very exciting. Then they threatened to beat Ann if she did not join them. Ann was deeply troubled. She did her best to avoid the group of the girls after classes, but they often waited for her outside the school and tried to persuade her to come with them. This problem is one which many school students in Hong Kong face. We asked the chairman of the local-fight-crime committee what Ann should do in these cases. "First of all, she could try to _ . Being caught stealing from shops could ruin their futures and it is simply not worth the risk," he said. "Young people may think that it is easy to get away with stealing from shops, but more and more stores now have plain clothes detectives who are dressed like customers. I would say shop thieves have a more than ninety percent possibility of being caught. "If they won't listen to her, Ann should turn to someone in charge in school, who can then decide if the matter can be dealt with by her."

[EX Q]: Article: The story of Graffiti is an interesting one. In the early 1970's, a New York City mailman used to travel across the city on the buses and subways to deliver his mail. He dreamt of riding on all the buses and subways in New York. His problem was that many buses and subways looked the same, so he would have to mark the buses and subways to know which one he had been on before. His name was Vic and his work ID was 156---so he left the mark VIC 156 on every journey he took. Soon people started to notice these sighs and wondered what they meant. When word got round what was happening, people would check the buses and subways to see if Vic had ridden on them. Other people decided they would take Vic's example and started leaving their own names. These marks became known as "Tags" . Tags became more color1ful and artistic and gangs of teenagers started leaving them on the walls in their neighborhood. This was to mark their area from other gangs.
