Article: Being safe in your everyday life needs knowledge . If you remember the following information, your life will be much safer. l Always notice the environment around you. You shouldn't walk alone outside. Make sure where the public phones are. If anything dangerous happens, you can find them easily. l Your bag should be carried towards the front of your body instead of putting it on your back. When a bus is full of people, it is easy enough for a thief to take away the things in the bag on your back. l If you are followed by someone you don't know, cross the street and go to the other way, let the person understand that you know he or she is after you. Next, don't go home at once. You are safer in the street than you are alone in your home or in a lift . l If you have to take a bus to a place far away, try to get to the stop a few minutes earlier before the bus leaves. This stops other people from studying you. On the bus, don't sit alone. Sit behind the driver or with other people. Don't sleep. Question: When you are followed by someone on your way home, you should _ to make yourself safe. Yes or no, is the answer "cross the street and go to the other way"?
Yes

Article: Masses of floating ice are so large that they dwarfs your ship, making you question whether your ship still can be spotted among such floating mountains. They are so improbable looking that you simply look in wonder. It seems that nothing that large could be natural-- and then it strikes you that something so large could only be natural. Now, people realize that as climate change is raising global temperatures, more icebergs are being born. Antarctica creates far more of them than Greenland, the source of bergs in Arctic waters. Antarctica's are also much larger, sometimes reaching the size of small countries. Recent data show the average atmospheric temperature has increased about 4.5degF in the western Antarctic Peninsula since the 1940s, making the region, among the fastest warming on earth. This jump has been shown in the recent breaking of major ice shelves along the Antarctic Peninsula. As a result, thousands of new icebergs have broken off, from ice shelves into the Southern Ocean at an accelerated rate. Even as more icebergs are being created, scientists are learning that these beauties are far from inactive masses of ice. In fact, they strikingly alter their environments biologically, chemically, and physically, making them islands of life in the open sea. Observers at sea had long remarked that they attract seals, and seabirds, and divers had noticed that fish are more numerous near them than in the surrounding sea. Now scientists are learning just what the attraction is all about. Depending on their size, location, and the season, icebergs can be nurturers or destroyers. During their existence--typically years from breaking off from an Antarctic or Greenlandic glacier to their gradual melting as they float into lower altitudes, they support animals on, around, even inside their splendid ice castle. They fertilize the ocean with nutrients, increasing sea creature production. Grounded bergs can shelter areas of the seafloor, protecting bottom-living creatures from free-floating icebergs. However,... Question: What can we learn from the passage? Yes or no, is the answer "Global warming has kept bringing icebergs into being."?
No

Q: Article: I was driving home one evening at about 5, caught in traffic, and the car started to die-- I hardly managed to get into a gas station, glad only that I would have a warm spot to wait for the tow truck . Before I could make the call, I saw a woman walking out of the " Quickie Mart" building, then suddenly she slipped on some ice and fell down, so I got out to see if she was okay. When I got there, it looked like she had been overcome by weep than that she had fallen; she was a young woman who looked _ with dark circles under her eyes. She dropped something as I helped her up, and I picked it up and gave it to her. It was a coin. At that moment, everything came into focus for me: the crying woman, the ancient Suburban packed full of stuff and three kids in the back, and the gas pump reading $4.95. I asked her if she was okay and if she needed help, and she just kept saying "I don't want my kids to see me crying," so we stood at the other side of the pump from her car. She said she was driving to California for Christmas and that things were very hard for her right now. I took out my credit card and swiped it through the card reader on the pump so that she could fill up her car completely, and I bought two big bags of food for her kids in the car who attacked it like wolves. While it was fueling, she asked, "So, are you an angel or something?" I said, "At this time of year, angels are really busy, so sometimes God uses common people." It was unbelievable to be part of someone else's miracle. And of course, you guessed it, when I got in my car it started right away and got me home with no problem. Sometimes, angels fly close enough to you that you can hear the flutter of their wings. Question: It can be inferred from the passage that _ . Yes or no, is the answer "the kids were extremely hungry at that time"?
A: No

Article: British and American scientists are raising genetically modified pigs in the hope of providing organs for transplant to humans, the project leader wrote in a newspaper Sunday. Scientists in London and California have begun conducting the genetic experiments to find a solution to record-long waiting lists for organ transplants, Robert Winston said in an opinion piece written for Britain's Sunday Times. In Britain alone, around 8,000 patients are waiting for a transplant. "People needing a new heart or liver are waiting for someone else to die -usually a violent death in a traffic accident," Winston wrote in the newspaper. He said his team was "trying to modify pigs so their organs might save the lives of humans." The scientists are introducing human genes into the animals to reduce the chances of the organs being rejected by patients, as has been common in previous attempts to use animal tissues, said Winston, who heads the Institute of Reproductive and Developmental Biology at London's Hammersmith Hospital. Working with Dr. Carol Redhead of the California Institute of Technology, Winston's team has injected human genes directly into male piglets , adding them to the animal's sperm . He said that pigs involved in experiments had successfully produced transgenic sperm, but acknowledged that British and European laws had prevented the team from using the pigs to mate. The Sunday Times newspaper reported that the experiments would be moved to the United States following difficulties with funding and regulations in Britain. It said the pigs would be bred in Missouri. "Our U.S. friends will benefit from our technology and the income we might have produced for Britain will be lost," Winston wrote. Some scientists have previously blamed the idea of using animal organs for human transplant, saying the technique risks spreading animal viruses to humans. Winston said his research project is attempting to breed virus-free pigs. Question: It can be inferred from the passage that _ . Yes or no, is the answer "examples of the animal tissues being rejected have happened"?
No
