Article: Humans have launched themselves into the outer space. They've landed on the moon. They've built habitable space stations that orbit the Earth. The next giant leap for mankind is to reach another planet - specifically, Mars. The problem is that it's no easy task. The planet is 586 times further away from the Earth than the moon, and it'll take around 180 to 220 days to reach Mars, depending on where each planet is in its orbit. Such long periods in space have suggested many potential health problems, including hormonal changes, skin conditions, and muscle and bone deterioration . Here's where some furry friends come in. A wide range of animals have been in space, from fruit flies and spiders to cats, and dogs. Such experiments began as far back as the late 1940s in first tests to see if living things could _ the extreme g-force of a rocket launch. Mice continue to play a very important part in space experiments, mainly because the animals make excellent test subjects. They're small, which makes them inexpensive and easy to care for. In addition, their size and short life span make it possible to do the equivalent of several human years of tests in a much shorter time. Finally, because mice are mammals, they share many common characteristics with humans in terms of genetics, biology and behavior. Astromice have hit the headlines recently, as a team of scientists led by Betty Nusgens, professor of biology at the University of Liege in Belgium, found that the mice suffered a 15 percent thinning of their skin after 91 days aboard the International Space Station (ISS). This experiment was part of a wider NASA mission called the Mice Drawer System (MDS). The Italian Space Agency developed the facility, which allows six mice to be housed, monitored, and automatically fed and watered aboard the ISS, among which three survived during the mission. The mice have participated in 20 separate experiments, to study such effects as osteoporosis , anemia and heart health. Results for the 20 experiments are coming in... Question: According to Betty Nusgens and her team, the mice aboard the ISS _ . Yes or no, is the answer "suffered the loss of part of their skin"?
No

Article: At first, the earth's surface layer was made up of huge blocks of hard, solid rocks. Then slowly, the rocks broke up into smaller and smaller pieces. Finally stones, pebbles and grains of sand were formed. Many sorts of plants and animals lived and died on the surface of the earth. Their remains mixed up with the stones, pebbles and formed soil. The outmost layer of the earth is soil. There are many ways in which large pieces of rock break into smaller ones. Wind, water, heat and cold help to break up rocks. When winds blow grains of sand against a large rock for a long time, the softer layers of the rock are slowly worn away. These leave holes and cracks in the rock, which become bigger and finally the rock breaks up into smaller pieces. The moving water of streams and rivers also helps to break up rocks. As the water moves along, it carries with it small pieces of rock. These rub the larger ones. Thus, the larger rocks are worn down to smaller pieces. The heat of the sun is also helpful to breaking up rocks. When the sun shines, the rocks become very hot. If these rocks are suddenly cooled, they may crack. Ice also plays a part in making soil. Water in the cracks can turn into ice in cold weather. As this happens, it becomes bigger and the cracks become wider, and finally break into smaller pieces. Question: Which of the following speeds up the breaks of rocks most? Yes or no, is the answer "Sharp changes in temperature."?
Yes

Q: Article: How to survive an earthquake prefix = st1 /Indonesia is located on the edge of the volcanic ring that circles the Pacific. This means volcanoes and earthquakes, which can cause serious loss of life. Many people there have heard suggestions of what to do in an earthquake. For instance, they are taught to stand in a doorway or, in a building, avoid the elevators and head for the stairs. Mr. Doug Copp is an expert on earthquakes and is the Rescue Chief and Disaster Manager of the American Rescue Team International. He has worked at every major disaster in the world since 1985. What his years of involvement have taught Doug is that when roofs and ceilings collapse they fall on objects and furniture, crushing them. Anyone hiding under a desk or a bed is always killed. However, Doug says the falling roofs and ceilings always end up forming triangle of space between the crushed object and the floor, what he refers to as Triangles Of Life. Instead of hiding under a solid object, lie on the floor next to it and you will likely have a space to survive. Doug says paper does not crush and usually where there are boxes of paper in an office building there will be a triangle space next to it. What about the old idea of standing in a doorway because the roof falls into the room? Dough says people who stand in doorways are usually killed, too. If the door falls forwards or backwards you will get crushed by the falling ceiling. If it falls sideways you will get cut in half by the doorway. What about stairs? Stairs have a different "moment of frequency " to the rest of the building and will swing back and forth until they collapse. Getting caught on a destroyed set of stairs means you will probably be injured or even killed by the different parts. Question: Who has the highest probability to survive an earthquake? Yes or no, is the answer "Betty, lying besides a pile of magazines."?
A: Yes

Article: On the wall in my mother's bedroom there was a photo, which showed a soldier with a gun. Below the photo was the word "Speaking". "Who's that soldier called Speaking?" I asked one day. "He was Harold." She said. "He was my only brother. When the Second World War began, Harold was eighteen. I was twelve then, and my sisters were ten and nine". "Harold liked to play with us, and we often quarreled. When we quarreled, we said:We're not speaking to you. But before long we were all happy again, and then we said: I'm speaking now. Are you speaking to me?" "When the war broke out, Harold joined the army. A month later, he came to see us. He brought the gun to show us. Then he went miles away to the war. We didn't see him for three years, three long, empty years. We didn't often hear from him. But one day in May there was a loud bang on the front door..." "I ran to open it. It was Harold! He was an old Harold, a thinner Harold. He looked at me with his two green eyes and smiled. That smile was just the same as before, then he said one word: 'speaking'". "I didn't...I couldn't...answer. I just fell into his arms and he dropped his gun. He stayed with us for a month. We played all our old games again. Then he went back to the war, and never came back again. So I wrote the word on the photo." Question: Harold never came back again because _ . Yes or no, is the answer "he died in the war"?
