*Question*
I'm taking a test and have to guess the right answer to the question after the article. Article: During the next several weeks I went completely to the wolves. I took a tiny tent and set it up on the shore of bay. The big telescope was set up in the mouth of the tent in such a way that I could observe the wolves by day or night. Quite by accident I had pitched (set up) my tent within ten yards of one of the major paths used by the wolves. Shortly after I had taken up residence one of the wolves came back and discovered me and my tent, but he did not stop or hesitate in his pace. Later, one or more wolves used the track past my tent and never did they show the slightest interest in me. I felt uncomfortable at being so totally ignored. The next day I noticed a male wolf make boundary markers by passing water on the rounds of his family lands. Once I had become aware of the strong feeling of property rights which existed among the wolves, I decided to use this knowledge to make them at least recognize my existence. One evening, after they had gone off for their regular nightly hunt I staked out a property of my own, including a long section of the wolves' path. In order to ensure that my claim would not be overlooked, I made a property mark on stones, dumps of moss, and patches of vegetation with a lot of tea. Before the hunters came back, task was done, and I retired, somewhat exhausted, to observe results. A few minutes later, the leading male appeared. As usual he did not bother to glance at the tent, but when he reached the point where my property line intersected (cut across) the trail , he stopped as suddenly as if he had run into an invisible wall. Cautiously, he extended his nose and sniffed at one of my marked bushes. After a minute of hesitation he backed away a few yards and sat down. Then, he looked directly at the tent and at me. His glare seemed to become more fierce as I attempted to stare him down. The situation was becoming intolerable. To break the impasse I turned my back on the wolf. Then quickly and with an air of decision, he turned his attention away from me and began a... Question: Why did the wolves manage to ignore the author's presence? Options: A: Because his tent was out of the wolves' estate boundaries. B: Because the author and the wolves were already good friends. C: Because they did not know him at all. D: Because the wolves were afraid of strangers.

I'm taking a test and have to guess the right answer to the question after the article. Article: When a rare disease ALD threatened to kill the four-year-old boy Lorenzo, his parents refused to give up hope. Doctors explained that there was no cure for ALD, and that he would probably die within three years. But Lorenzo's parents set out to prove the doctors wrong. The parents devoted themselves to keeping their son alive and searching for a cure. But doctors and the families of other ALD patients often refused to take them seriously. They thought the efforts to find a cure were a waste of time, and drug companies weren't interested in supporting research into such a rare disease. However, the parents still refused to give up and spent every available hour in medical libraries and talking to anyone who would help. Through trial and error, they finally created a cure from ingredients commonly found in the kitchen. The cure, named "Lorenzo's Oil", saved the boy's life. Despite the good results, scientists and doctors remained unconvinced. They said there was no real evidence that the oil worked and that the treatment was just a theory. As a result, some families with ALD children were reluctant to try it. Finally, the boy's father organized an international study to test the oil. After ten years of trials, the answer is: the oil keeps ALD children healthy. Question: From the passage we can conclude that _ . Options: A: doctors remain doubtful of the effectiveness of the cure B: many ALD patients still refuse to use the oil C: various cures have been found for ALD D: the oil really works as a cure for ALD

I'm taking a test and have to guess the right answer to the question after the article. Article: Have you ever remembered something with your nose? Maybe the smell of hot dogs makes you think of being at a baseball game. Or the smell of barbequed meat reminds you of a night around a fire. Scientists know that smells can make people think of powerful memories. Wouldn't it be great to somehow save those memories? _ is exactly what Mark Crames, a businessman making perfumes , is trying to do. His company, Demeter Fragrance, makes more than 200 kinds of perfumes. "Imagine every smell in the world as a musical note," Crames said. "We try to join those notes to make a piece of beautiful music." He has made many perfumes and he got the idea from plays, storms and even animals. Everyday smells mean different things to different people. "A perfume called Poison Ivy might make you think of sadness or surprise," Crames says. "But it could make another person think of a great time at summer camp." Crames produces perfumes using a high-tech method called headspace technology. This month, Crames is making scent for Tootsie Roll and Junior Mints. Not every smell can be easily copied. "One of our most needed perfumes is a little dog's breath," he says. "But it is so chemically complicated that it's very hard to get." What scent would you like to bottle? A zoo? Or grandma's old house? Crames may be able to help you bring back your memories, so all you have to do is have a smell when you want to remember. Question: Which part of a website can this passage come from? Options: A: Fashion. B: Science. C: Business. D: Art.

I'm taking a test and have to guess the right answer to the question after the article. Article: Take control of your health by learning these four numbers. They'll help with everything from losing weight to protecting your heart. Your daily calorie needs This is not technically a measurement, but it can have a huge influence on your health. Most women need 2,000 calories a day for good health, and men generally need about 2,550. One way to work out your daily calorie needs is to multiply your weight in pounds by 13 to 15, depending on your activity level. But roughly, that's 300 to 400 calories for breakfast, 500 to 600 for lunch, and 600 to 700 for dinner. Trying to lose weight? Eat about 500 calories less. Your waist size Waist size is one of the best ways to measure whether your weight is affecting your heart health. When body fat is packed into your abdomen ,your risk of heart attack increases. For women, health risk begins to rise when your waist is more than 35 inches. For men, risk increases with a measurement when your waist is over 40 inches. Your blood pressure Blood pressure rises and falls normally during the day. When it remains high, you have high blood pressure and this carries a higher risk or heart disease and stroke. A reading of 140/90 mm Hg or more is considered high, and if it's between 120/80 and 139/89, you may still be at risk and should be taking steps to prevent the development of high blood pressure. Your morning pulse rate Your pulse rate is the number of times your heart beats in one minute. A normal resting pulse rate is 60 to 90 beats per minute. People who are fit tend to have lower resting pulse rates because their heart muscles are in good shape. But if you don't exercise regularly and your heart rate is lower than the normal range, tell your doctor--it could be a sign of heart disease. Question: What should you do if your blood pressure is 128/83 mm Hg? Options: A: Take measures to stop it going high. B: Leave it as it is as there was no risk. C: Measure the blood pressure regularly. D: Go to see a doctor for advice.
