Question: Article: The European Union on Monday prohibited the use of X-ray body scanners in European airports, parting ways with the U. S. Transportation Security Administration, which has used hundreds of the scanners as a way to screen millions of airline passengers for explosives hidden under clothing. The European Commission, which enforces common policies of the EU's 27 member countries, adopted the rule "in order not to risk doing harm to citizens' health and safety." As a ProPublica/PBS NewsHour investigation detailed earlier this month, X-ray body scanners use ionizing radiation ,a form of energy that has been shown to damage DMA and cause cancer. Although the amount of radiation is extremely low, equal to the radiation a person would receive in a few minutes of flying, several research studies have concluded that a small number of cancer cases would result from scanning hundreds of millions of passengers a year. European countries will be allowed to use an alternative body scanner relying on radio frequency waves, which have not been linked to cancer. The U. S. Transportation Security Administration (TSA) has also used hundreds of those machines --known as millimeter-wave scanners --in U. S. airports. But unlike Europe, it has decided to use both types of scanners. The TSA would not comment specifically on the EU 's decision. But in a statement, TSA spokesman Mike McCarthy said, "As one of our many layers of security, TSA uses the most advanced technology available to provide the best opportunity to detect dangerous items, such as explosives. " We strictly test our technology to ensure it meets our high detection and safety standards before it is placed in airports," he continued. "Since January 2010, advanced imaging technology has detected more than 300 dangerous or illegal items on passengers in U. S. airports nationwide." Body scanners have been controversial in the United States since they were first used in prisons in the late 1990s and then in airports for tests after 9/11.
Answer: They won't risk causing cancer.

Answer: Which of the following is true about the new body scanners to be used in Europe?.

Question: Article: Global warming happens when greenhouse gases trap heat and light from the sun in the earth's atmosphere, which increases the temperature. This is like when heat is trapped in a car. On a hot day, the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car, by going through the windows,but it can't get back out. This is what the greenhouse effect does to the earth .The heat and light can get through the atmosphere, but it can't get out As a result,the temperature rises. Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on Without _ ,the earth would be freezing,or it would be burning hot. It would be freezing at night because we would not get the sun's heat and light .During the day, especially during the summer, it would be burning because the sun would be up with no atmosphere to filter it,so people,plants,and animals would be exposed to all the light and heat. Although the greenhouse effect makes the earth able to have people living on it,if there gets to be too many gases,the each can get unusually warmer, and many plants,animals.and people will die. Plants would die because they would not be able to take the heat .This would cause us to have less food to eat, and it would also limit the food that animals have. With less food for the animals that we need to survive we would even have less food. Gradually, people,plants,and animals would all die of hunger. People are doing many things to try to stop global warming .One thing is carpooling--driving with someone to a place that you are both going to. Another thing is being more careful about leaving electrical devices turned on. Now, more people are even riding buses or bikes to lower the amount of greenhouse gases in the air .Although adults do many things to help stop global warming, kids call do just as much.
Answer: It prevents all the light from the sun shining on the earth.

Answer: What is the effect of atmosphere?

Question: Article: I was thirteen when my father got hurt.Looking back over the years, I sometimes wonder what I could have done differently that day.Spit twice over my shoulder when I saw the single magpie , maybe.But that's the thing about superstitions .You don't know how much power they have until you break them. We lived in a dark shabby house in Bucks.Wood blocks laid over dirt on the floor.That part of England was full of cherry trees.Chalky soil. The rice had caught in the bottom of the pot that morning at breakfast and all I could smell was burned rice.Even now when I think of that day I have the taste of burned rice in my mouth. "I'm going to cut down the old cherry tree," my father announced. "You've been saying that for years," said my mother lightly touching the end of her nose.Her nose ran all year long.Her arms rested on the table, a cup of tea placed between her hands, steam rising into the air."You'll never get round to it." My stomach, balled into a tight little knot relaxed itself. "Millie's going to cry if you cut it down," said my younger brother, Simon, his eyes bright as a fox."Silly Millie, silly Millie." "Hold your noise," said my father patting Simon on the head."And put back that butter.That's a week's ration you've got on your plate." "The war's over," said Simon in a low voice."We haven't had rationing for ages." Simon was right.Even sugar had come off points.However, we still occasionally received food parcels from distant cousins in Canada. My father glared at him and then went on. "Pigs.Burt says he'll come and help me take the tree down if he can have some of the wood." "No," I said springing to my feet."You can't do it.That's my tree.Always has been.Always will be.I won't let you." Tom, took a piece of toast, watching my reaction.My older brother, he knew what the tree meant to me. "Now then, Millie," said my father softening his face."That tree's wild.It's in the way."
