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  ... When a population is said to be aging,  _  . A) there are more people retiring than those entering the workforce B) the birth rate in the area must be lower than that of death there C) there should be an oversupply of the workforce members D) there are more people entering the workforce than those retiring

Every year, millions of Americans see their personal information leak into the wrong hands. Maybe there's spyware on the their computer, or a service they use suffered a security reach, leaving customers at the risk of exposure. Or perhaps their password is easy to guess. Don't fear: You can easily set up proper defenses. Here's how. * Clean Your Computer and Smartphone Before you put new security measures into place, make sure your devices are as spotless as possible. This means installing a good antivirus program and taking the time to clear out any spy -- or malware that may have already infected your system. These days, it's also worth it to make sure your phone is safe from viruses. Iphones are less likely to be targeted by spyware, but Android users should download the Lookout app to scan their devices and ensure everything is as it should be. * Secure Your WiFi. It's fairly easy for potential criminals to gain access to your information if they're able to share your connection -- that's why you want to be careful when using public WiFi. Even though you put security measures into place a couple of years ago, it's a good idea to refresh your settings. * Use passwords What you've heard is true: Passwords should use a variety of special characters, numerals, letters, and cases when possible. * Check the shopping security Take care when shopping online. Always check the security symbols when using an online site for shopping. If the lock icon encryption    is not there, do not give out credit details. Also, check that the site is legal -- never go to a site from a random email and start shopping online. Keep a separate credit card just for online shopping. This will make it easier to cancel if something bad does happen and your other credit card for "in real life" can still be used uninfluenced. Don't store information on any store's website. It may be convenient but it's also a possible loss to you if the site is hacked. Which of the following is an improper way to shop online? A) Adopting a unique password for every website. B) Shopping online at reliable websites. C) Keeping credit details safe by checking security symbols. D) Monitoring credit card by storing information online.

You've heard the saying: if you don't know where you're going, how will you know when you get there. Thousands of successful people attribute (......) most of their success to goal setting. Knowing this, why don't the majority of people set goals? Goal setting starts within you. You have to believe it's possible to do a thing before you have a strong desire to write it down on paper and take steps to make it happen. How do you possibly bring yourself to believe in your own success? After all, so many of you have been at this success thing for a while and it still hasn't happened to you. Companies that you believed in and worked hard for have failed, your family and friends are waiting for you to "be realistic", and life just keeps giving you one blow after another. But there is a small fire burning inside you. You keep at it because all you know is you can't continue to get up every morning, go to work for someone else and allow them to determine how much you're worth each week which is far below your true value. So where do you go from here? Where do you start today? The road to inner belief in your success begins with you telling yourself every day, throughout the day, that you can do what you set out to do, you can have what you set out to get, and you can be that successful person you know that lives inside you. Yes, obstacles will come, doubters will be around, but don't you be one of them. Treat yourself like the person you love and care about most. If you had children who had a paper route and they wanted to accomplish a goal but they kept running into obstacles, what would happen? They would soon become discouraged with so many people telling them no. I'm not interested in what you have to offer. What would you say to your child? I'm sure it won't be the same thing you've been saying to yourself. Turn your words around. Speak those same words of encouragement you would speak to your discouraged child, to yourself. If you would never put a loved one down, especially when they are feeling discouraged,... What does the author mean by saying "Turn your words around"? A) You should speak words of encouragement to your discouraged child. B) You shouldn't put a loved one down. C) You should encourage yourself. D) You should change the subject of the conversation.

My father' s response to the bank building at 43rd Street and Fifth Avenue in New York city was immediate and definite: "You won' t catch me putting my money in there!" he declared, "Not in that glass box. " Of course, my father is a gentleman of the old school, a member of the generation to whom a good deal of modern architecture is upsetting, but I believe that his negative response was not so much to the architecture as to a violation of his concept of the nature of money. In his generation money was thought of as a real commodity  that could be carried, or stolen. Therefore, to attract the custom of a sensible man, a bank had to have heavy walls, barred windows, and bronze doors, to make sure of the fact, however, untrue, that money would be safe inside. If a building' s design made it appear strong, the institution was necessarily reliable, and the meaning of the heavy wall as an architecture symbol showed the general attitude toward money. But the attitude toward money has, of course, changed. Except pocket money, cash of any kind is now rarely used; money as a tangible commodity has largely been replaced by credit. The banker no longer offers us a safe: he offers us a service in which the most valuable factor is the creativity for the invention of large numbers. It is in no way surprising, in view of this change in attitude, that we are witnessing the disappearance of the heavy-walled bank. Just as the older bank emphasized its strength, this bank by its architecture is proud of imaginative powers. According to this passage, a modern banker should be   _  . A) ambitious and friendly B) reliable and powerful C) sensible and strong D) imaginative and creative
