Please answer this: Write a multi-choice question for the following article: Article: Winter is a great time to experiment with new sports. The key is to find one that matches your interests and natural abilities. If you like to walk, keep walking -- on snowshoes. If you want to try an endurance sport, go for cross-country skiing. Besides, snowboarding is just great fun.  Not satisfied with these? Try downhill skiing, then. Downhill skiing is not as hard as it used to be -- shorter, lightweight, curved skis make any beginner feel like an Olympic winner. These newer skis -- along with another type of equipment called skiboards, which are even shorter than skis -- help you control your speed and body movements.  Consider testing the latest high-tech skis or snowboards?Check with your local sports shops or the rental places at the ski mountains about sample programs.  You could also try sledding. Use a wood-framed sled with steel runners or a plastic sled to head down a snowy hill. If you prefer ice to snow, think hockey or figure skating.  Runners can also train during the winter in spite of wet or slippery roads. One of the easiest sports around, snowshoeing can be excellent cold-weather cross-training for runners and cyclists -- or anyone wanting to take a wintry walk in the woods. Snowshoes are smaller, lighter, and better than ever. If you want to try them out, you may be able to rent a pair for a day at many of the larger outdoor or sporting goods stores.  Whatever sport you choose, don't rely on a friend for instruction. You wouldn't let an inexperienced doctor perform a brain operation on you, but why let one teach you to ski or skate? That's what instructors are for -- to help newcomers start out right. Instructors can give you advice about equipment, techniques, safety, and dealing with injuries if they do happen to you.  Above all, if you want to progress, invest your time in learning the basic skills thoroughly. Everything else you do as a skier, boarder, or skater will be built on these first skills.

Please answer this: Write a multi-choice question for the following article: Article: Many scientists today are convinced that life exists elsewhere in the universe---life probably much like that on our own planet. They reason in the following way.   As far as astronomers can determine, the entire universe is built of the same matter. They have no reason to doubt that matter obeys the same laws in every part of the universe. Therefore, it is reasonable to guess that other stars, with their own planets, were born in the same way as our own solar system. What we know of life on earth suggests that life will arise wherever the proper conditions exist.   Life requires the right amount and kind of atmosphere. This eliminates  all those planets in the universe that are not about the same size and weight as the earth. A smaller planet would lose its atmosphere; a larger one would hold too much of it.   Life also requires a steady supply of heat and light. This eliminates double stars, or stars that flare up suddenly. Only single stars that are steady sources of heat and light like our sun would qualify.   Finally, life could evolve  only if the planet is just the right distance from its sun. With a weaker sun than our own, the planet would have to be closer to it. With a stronger sun, it would have to be farther away.   If we suppose that every star in the universe has a family of planets, then how many planets might support life? First, eliminate those stars that are not like our sun. Next eliminate most of their planets; they are either too far from or too close to their suns. Then eliminate all those planets which are not the same size and weight as the earth. Finally, remember that the proper conditions do not necessarily mean that life actually does exist on a planet. It may not have begun yet, or it may have already died out.   This process of elimination seems to leave very few planets on which earthlike life might be found. However, even if life could exist on only one planet in a million, there are so many billions of planets that this would still leave a vast number on which life could exist.

Please answer this: Write a multi-choice question for the following article: Article: The Atacama Desert is located just west of the Andes, a 1000-km strip  of land next to the Pacific Ocean. In spite of its location beside the sea, several studies have shown that this region is the driest place in the world. In the Antofagasta Region of the desert, the average annual rainfall is just 1 mm and some weather stations have never received rain at all. Atacama is so  _ that the surrounding mountains that reach up to 6885 m, have  ly no glaciers! In the region, the river beds have been dry for over 120,000 years. However, unlike the Sahara Desert,Atacama is surprisingly not that hot. It has an average daily temperature between 0'C and 25degC! If you find that surprising, you'd be shocked to find out that this desert has lakes!  When there was rainfall in the region (many year ago), this accumulated water created what we now know as the Salt Lakes. The name of these lakes was given as a result of the effect of the Atacama environment: the long dry period makes the water evaporate ,resulting in the higher concentrations of salt in the remaining water. This region has been tested by scientists to see if life is present in the Atacama soil with the same instruments that would be used to detect life in the soil on Mars! As a result of the soil's similarites to that of Mars,the Atacama land is used to test instruments for future Mars missions. In addition, the region has been used in movies as a set for filming Mars scenes, most famously in the television show Space Odyssey: Voyage to the Planets.  The Atacama Desert is truly a unique place, due to its lack of rain as well as its similarities to Mars. You would think that this place would be a bare ghost town  , but think again! Many people have lived here for centuries, giving this desert its own culture and economic significance.
