The coming "demographic cliff" will see vast numbers of skilled workers disappear from the labor force. The workforce is ageing across the rich world. Within the EU the number of workers aged between 50 and 64 will increase by 25% over the next two decades, while those aged 20 -29 will decrease by 20%. Given that most societies have a tendency to retirement at around 65, companies have a problem of knowledge management, of making sure that the boomers do not leave before they have handed over their expertise along with the office keys and their e-mail address. If you look hard enough, you can find companies that have begun to adapt the workplace to older workers. The tools they use to achieve are flexible working, telecommuting, and so forth. Some companies spend "a lot of time" on the ergonomics its factories, making jobs there less tiring.

" Why are firms not working harder to keep old employees? Mostly they are not hanging on to older workers the only way to cope with a falling supply of labor.

Article: Cooking is an important skill with an interesting history. Every culture has their own types of foods and methods of cooking. Most cities and towns have local specialties and dishes. Families often have special recipes and meals that nobody else knows how to cook. Food comes in almost as many shapes, sizes, and varieties as people do. And behind every meal and every dish there is a cook. In many cultures, especially in the West, cooking has traditionally been a task more often performed by women than by men. Today, however, it would be foolish to say cooking is only for females. Even though people are becoming busier and busier with their jobs, more and more people are cooking, including men. People cook to relax, to save money, to eat healthier foods, or just to eat tastier foods. This activity has become so popular that in the United States there is a television channel that does nothing but teach you how to cook. The internet has made it easier and easier to get all kinds of recipes. Because of globalization more types of spices and ingredients are available to more people at cheaper prices. This has helped contribute to new types of foods, dishes, and styles of cooking. Simply put, cooking is on the rise. In most places you can survive without knowing how to cook. But in my opinion if you don't know how to cook, you had better know somebody else that can cook, or life just won't be as enjoyable. Question: Why is cooking becoming more popular? Yes or no, is the answer "There are many reasons for the increase in popularity."?

Article: As long as you have broadband service in your home, you can turn on your desktop computer and connect to the Internet. If you have a wireless router , a device that spreads the broadband connection to other devices, you can set up a Wi-Fi network, which enables your cellphones and tablets go online too. And when you are outdoors where is no Wi-Fi, such as in the park or at the beach, having 3G service allows you to stay connected. It seems that lots of us have Internet coverage everywhere we go. So why have mobile companies around the world lately been so enthusiastic about a new term, "4G"? First, you need to know that the letter :G" stands for "generation". Even if you have no idea what 4G is, at least you can figure out that it is a step up from 3G since it's the latest generation of mobile internet service. Unlike broadband, mobile Internet uses the same signal towers that provide voice service to your cellphone, which means wherever you can make phone calls with your cellphone you also have an Internet connection. But mobile connections have their _ : they don't carry as much information as broadband does, making opening websites and downloading music slower than they are on a Wi-Fi connection. This is why mobile connections have been constantly upgraded since the first generation was launched back in the 1980s. According to BBC, 4G is five to seven times faster than current 3G network speeds, almost as fast as home broadband. Because of this, 4G is widely suited for services like video downloading, mapping, online shopping and even video conferencing. To achieve the high speeds, network companies have to spend a lot of money on building new signal towers, which will eventually lead to a higher phone bill if you switch to 4G, and you will also have to get a new phone with 4G capacity. Question: What does the author think of 4G service? Yes or no, is the answer "It provides good service at a higher price."?

Article: When I was a boy,I belonged to the Boy Scouts ,so I used to go camping every summer,and once something happened which I have never been able to explain. We were camping in a place above a river. After arriving,we all rushed down to the river and had a swim. Standing by the river,we noticed that it was surrounded by cliffs . If someone wanted to reach the river at this point,he had to walk past our camp. Several days later,the scoutmaster had to he away for a day. That afternoon,we had supper early. We were sitting round the fire,eating and talking,when a man walked past and went down towards the river. We all felt that this man looked very strange,but,because each of us was afraid of looking very stupid,no one said anything. We ate rather slowly,taking as long as possible. After finishing,we collected our plates together so that we could take them to the river where we always washed them. But no one moved towards the river-- we stood looking at each other ashamed. Then all shouting at once, we began talking about the man who had walked past us. We agreed how strange he looked and we wondered what he could be doing by the river. We knew that he could only return by passing through our camp. An hour passed. Then one of the boys suggested we should creep down by the river so that we could see what the man was doing. Moving very slowly and keeping in the shadow, we crept down towards the bank. One boy climbed a tree so that he could see everything clearly. He called to us that there was no one there,so we ran down to the bank, looking every-where carefully. We could not understand where the man had gone. When it got dark,we went back to our camp feeling bewildered. We told the scoutmaster what had happened in the evening. Smiling,he doubted that we had seen the man,but finally suggested we go and look again. We did,but there was no one there. Many years have passed,but I still remember it as if it were yesterday. What did we see?I do not know. Question: The word "bewildered" in the text probably means _ . Yes or no, is the answer "unable to understand"?
