I love seeing Europeans line up in airports to applaud arriving refugees. But humanitarianism will not guide policy for long. We liberals need to argue from Europe's self-interest: our continent has the need, the space and the ability to accept people. Many European countries are gradually turning into old people's homes. Germany, Italy, Spain and others have some of the lowest birth rates in human history. It is predicted that about one-third of their populations will be aged over 65 in 2050. Germany needs to import at least 350,000 people a year to keep its workforce stable. Suddenly, young ambitious workers are pouring into the country as if called by a genie with a lamp. No wonder Angela Merkel, German Chancellor, has been more welcoming than David Cameron, British Prime Minister. But all over Europe, carers for old people are already in need. Norway found oil under the seabed but it would have been better off if it had discovered 50,000 nurses there instead. Many rightwingers think we have reached our limits. This feeling is widespread. And it's true that Western Europe is one of the most densely populated regions on earth. Indeed, density has long been Europe's unique selling point: with so many people of different nations closely packed together, we have always traded goods and exchanged ideas fast. That's why the scientific revolution of the 16th and 17th centuries happened here. But we have plenty more room. Many European cities aren't dense enough. Now east Germany, north-western Spain and gorgeous mountain villages in Italy are losing people. Lots of cities have unused industrial land. Humans inhabit a slice of the EU's territory. Only about 2.5 per cent of the EU's land is used for housing, estimates the European Commission. By contrast, a whopping 43 per cent was used for agriculture in 2009, it says. That's too much. We could turn more land into forest or into green landscapes where people can relax and play. Making that transition is feasible because we now use agricultural land... Which of the following statements is TRUE? A) No other region is more densely populated than Western Europe. B) Density has become Europe's most outstanding characteristic. C) All European cities are not crowded together in great numbers. D) Large quantities of unused industrial land will turn into forest.

There's nothing like a good night's sleep -- but what does that really mean? It turns out that the answer depends not only on your age, but also on your lifestyle. Some people are productive and happy with fewer hours of sleep, while others need more. Still, experts can determine guidelines that work for most people. The National Sleep Foundation researched the topic and gave new recommendations this week. The foundation acknowledges that sleep needs will vary -- lifestyle and stress should be taken into consideration -- but their recommendations offer a general guideline. For example, teenagers (14 --17 years old) need 8--10 hours' sleep every day. To create the recommendations, some sleep and medical experts reviewed 312 articles from journals published during the last decade. This is the first time that any professional organization has developed age-specific recommended sleep durations based on a systematic review of the world scientific literature. A lack of sleep can be linked to weight gain, because that causes an increase in appetite, according to the foundation. It can also have serious consequences on the brain. People who do not get enough sleep are at increased risk for depression, and can endanger others. Those that become sleepy while driving, for example, risk both their lives and the lives of those around them. Researchers also have found in the past that too much sleep can have negative effects. Low socioeconomic status and depression reportedly are significantly associated with longer sleep. However, experts nowadays find that research on oversleeping is still unconvincing and needs more attention. Currently, there is no strong evidence that sleeping too much has health consequences. There is, however, laboratory evidence that short sleep durations of four to five hours have negative consequences. We need similar laboratory studies to determine whether long sleep durations result in physiological changes that could lead to disease before we make any recommendations against sleep extension. The research shows that people without enough sleep will _ . A) lose some weight B) drive faster than usual C) dream during their sleep D) eat more food

The vast majority of fitness trackers count your steps and are worn around the wrist, but now there's a device that's designed to be worn like a necklace and monitors tiny movements to improve your posture. The Fineck device aims to address neck pain by tracking tiny movement, spotting bad habits and suggesting exercises via an accompanying app. Made from silicone and titanium , Fineck monitors a wearer's movement, balance, posture and movement thanks to sensors inside. The Mountain View California-based firm says that a high percentage of people suffer from neck pain and associated problems, probably caused by more individuals doing office jobs, which generally involve leaning over computer keyboard. The device contains sensors, several different types of instruments to monitor movement, plus a monitor to shake. It connects to an IOS app via Bluetooth so that wearers can see their bad habits and play "neck training" games. The app warns of health risks and records a user's activity to build up a customer personal health description. The necklace shakes to give smart advice, such as reminding wearers to sit up straight. The app also allows users to set goals, like many other wearables do. "Fineck is the first wearable device for your neck that tracks your neck activity and warn you when you are in a bad posture for too long. You can also exercise your neck with Fineck's interactive games." The company writes on Kickstarter. "No matter where you are and what you are doing at office, on the go, or simply just feeling bored, Fineck will bring you enriched exercise experience through motion sensing games and therapies." It also claims that it is "the world's first titanium wearable device". The metal is widely used in fashion stuff that you can wear or carry to match your clothes because it is lightweight, durable and does not tend to cause allergic reactions. It also offers additional features such as shaking to indicate alerts on a user's smartphone, but it is not currently clear whether it can also be used... Which of the following statements is true? A) The Fineck takes an hour to charge and is available at any time. B) Movie stars like to wear necklace made of silicone to match their clothes. C) The device count the steps to help wearers to see their bad habits. D) Neck-ache is something caused by using computers too much.
