Question: Read the following article and select the best answer. Article: Space is where our future is -- trips to the Moon, Mars and beyond. Most people would think that aside from comets  and stars, there is little else out there. But, since our space journey started we have left so much trash  there that scientists are now concerned that if we don't clean it up, we may all be in mortal  danger. The first piece of space junk was created in 1964, when the American satellite Vanguard I stopped operating and lost its connection with the ground center. However, since it kept orbiting around the Earth without any consequences, scientists became increasingly comfortable abandoning  things that no longer served any useful purpose in space. It is estimated  that there are now over 500,000 pieces of man-made trash orbiting the Earth at speeds of up to 17,500 miles per hour. The junk varies from tiny pieces of paint chipped off rockets to cameras, huge fuel tanks, and even odd items like the million-dollar tool kit that astronaut Heidemarie Stefanyshyn Piper lost during a spacewalk. The major problem with the space trash is that it may hit working satellites and damage traveling spacecraft . Moreover, pieces of junk may collide  with each other and break into pieces which fall back to the Earth. To avoid this, scientists have invented several ways for clearing the sky. Ground stations have been built to monitor larger pieces of space trash to prevent them from crashing into working satellites or space shuttles. Future plans include a cooperative effort among many nations to stop littering in space and to clean up the trash already there. Question: What was the first piece of man-made space trash? - A camera. - A tool kit. - A fuel tank. - A broken satellite.
A broken satellite.
Read the following article and select the best answer. Article: Trying to recover from a devastating economic crisis, Spain is considering moving the country's clock back by one hour. Many people regard long afternoon naps and late dinners as perfect aspects of the Spanish way of life. Until the 1940s, Spain was on the same time as Britain and Portugal. In World War II, Spain and Portugal moved the clocks forward to align them with Nazi Germany. The same happened in Portugal. After the defeat of Hitler, Portugal returned to Greenwich Mean Time, but Spain did not. "The fact that for more than 71 years Spain has not been in its proper time zone means we sleep almost an hour less than the World Health Organization recommends," lawmakers in the Spanish Parliament wrote in a proposal."This has a negative effect on productivity, absenteeism, stress, accidents and school drop-out rates." Last September, a parliamentary commission recommended that the government turn back the clocks by one hour and introduce a regular eight-hour workday. For the time being, the Spanish government is treating the campaign seriously but it hasn't taken any action yet. Spain's time zone issue explains why everything in Spain happens later, from meal times to broadcast entertainment (primetime doesn't start until 10 pm). Many urban Spaniards complain of a never-ending workday that begins in the morning but is interrupted by a traditional late-morning break and then again by the midday siesta--a two-hour long lunch and nap that usually start at 2 pm. If workers return to their desks at 4 pm, they end up working late into the evening. Under the proposed new schedule, the lunchtime break would be cut to an hour or less. The interruption-filled Spanish workday would be replaced by something closer to a 9-to-5 schedule. Ignacio Buqueras, president of the Association for the Rationalization of Spanish Working Hours, told The New York Times that changing the Spanish schedule would be good news for working mothers. It would also allow families more free time together and boost Spain's economic... Question: Which of the following is the best title for the passage? - Lifestyle changes in Spain - Time for Spain to turn back - Spain's time zone issues - Spain's work hour regulation
Time for Spain to turn back
Q: Read the following article and select the best answer. Article: They found that young people who often use social media are more likely to suffer from sleep disorders than those who use social media less. The researchers set out to examine the connection between social media use and sleep among young adults. Levenson, who led the study, noticed that these young adults are possibly the first "generation to grow up with social media." The researchers wanted to find out how often young people used social media sites like Facebook, Twitter, Histogram, etc. For the study, they gave questionnaires to nearly 1,800 adults, aged 19 to 32. On average, members of the study group used social media sites one hour a day. They also "visited various social media accounts 30 times per week." Thirty percent of the study's participants  reported having serious problems with sleeping. Those people who used social media a lot were three times more likely to have a sleep disorder. And those who spent the most time on social media were two times as likely to suffer from sleep disorders. Levenson said the number of times a person visits social media is a better predictor  of sleep problems than overall time spent on social media. If this is true, she adds, then practices that stop such behaviors may be most effective. Question: What is the passage mainly about? - How should young adults use social media correctly? - Social media is keeping young adults awake. - Social media have great effects on young adults. - How should young adults have a good sleep?
A: Social media is keeping young adults awake.

Read the following article and select the best answer. Article: The Goldman Environmental Foundation recently recognized a group of individuals   for their efforts to protect the environment. Each year, the American-based group honors environmental activists from six different areas. The first three winners of the 2012 Goldman Prize are from Kenya, the Philippines and China.  The Goldman Environmental Foundation says Ikal Angelei is a hero to those who live around Lake Turkana. The Kenyan woman received the award because of her efforts to stop a dam project on a river in Ethiopia. Critics say the dam will harm the lake and restrict   the flow of water for people who live nearby.  The Philippine island of Mindoro is home to those who depend on the area's natural resources for food and jobs. Edwin Gariguez became concerned when a European company announced plans to mine for nickel   on the island. The Roman Catholic minister said waste materials from the mining project would pollute the water and destroy the forests. So he started a campaign to stop the project. In China, Ma June is working with businesses to clean up their pollution. He formed a group that collects information about pollution, and publishes it on the Internet.  The Goldman Prize was also awarded to activists from Argentina, Russia and the United States.  Sofia Gatica of Argentina is from a town where farmers commonly use pesticide   products to protect soybean crops from insects. The town also has a high rate of cancer. Miz Gatica believed that pesticide use was responsible for the death of her baby. She worked with other mothers to get government officials to ban the use of chemicals near populated areas. Evgenia Chirikova objects to the plans to build a road through a protected forest just outside Moscow. She has demanded that Russian officials redirect the road away from the forest. She and her followers have been arrested for their activities. However, their campaign has gained widespread public support. The sixth winner is American Caroline Cannon -- a community leader in Point Hope, Alaska. Miz...
