[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: Many years ago, when I was fresh out of school and working in Denver, I was driving to my parents' home in Missouri for Christmas. I stopped at a gas station about 50 miles from Oklahoma City, where I was planning to stop and visit a friend. While I was standing in line at the cash register , I said hello to an older couple who were also paying for gas. I took off, but had gone only a few miles when black smoke poured from the back of my car. I stopped and wondered what I should do. A car pulled up behind me. It was the couple I had spoken to at the gas station. They said they would take me to my friend's We chatted on the way into the city, and when I got out of the car, the husband gave me his business card. I wrote him and his wife a thank-you note for helping me. Soon afterward, I received a Christmas present from them. Their note that came with it said that helping me had made their holidays meaningful. Years later, I drove to a meeting in a nearby town in the morning. In late afternoon I returned to my car and found that I'd left the lights on all day, and the battery was dead. Then I noticed that the Friendly Ford dealership - a shop selling cars - was right next door. I walked over and found two salesmen in the showroom. "Just how friendly is Friendly Ford?" I asked and explained my trouble. They quickly drove a pickup truck to my car and started it. They would accept no payment, so when I got home, I wrote them a note to say thanks. I received a letter back from one of the salesmen. No one had ever taken the time to write him and say thank you, and it meant a lot, he said. "Thank you" - two powerful words. They're easy to say and mean so much.
