Question: Read the following article and select the best answer. Article: Bamboo flooring is a growing trend in home flooring and is also a great improvement to traditional hardwood floors.It is the most environmentally friendly kind of natural flooring that you can select for your home.It is also a renewable resource,is stronger than steel,and does not suffer from problems as a result of temperature changes. Bamboo is one of the fastest growing plants on earth,and only takes five years to grow to adult form.Bamboo is harvested every five years,and starts to re-grow immediately after being harvested.For this reason,bamboo is a kind of grass,not a tree.Bamboo is hollow but very hard and can stand up to 50,000 pounds of pressure per square inch. Bamboo flooring has become very popular with its rich and beautiful golden earth colors.But it is important to shop around for a good-quality bamboo flooring product that contains no formaldehydes ,which is said to be the best kind of bamboo flooring.Many brands use cheaper bamboo that may contain formaldehydes,and this can cause indoor air pollution problems as certain chemical materials in the bamboo slowly release their pollutants into the air. So,why should we turn to bamboo to save the enviroment?In fact,bamboo cannot save the environment directly,but it is an excellent replacement product for much of the hardwood species of trees that are being harvested in rainforests.Once harvested,if these hardwood trees do grow back,it can take up to 200 years!Rainforests are the lungs of our planet and they make a significant contribution to global oxygen production. By selecting bamoo flooring,you can reduce the demand for hardwood materials and help save the environment for future generations.Of course,everyone wants to buy good-quality bamboo flooring.The brands from our shop are very high in quality and have received a lot of public praise. Question: The author wrote this passage in order to _ . - explain the importance of bamboo flooring - tell us his or her own bamboo flooring brands are good - tell people to care more about the environment - discuss the history of hardwood flooring

Question: Read the following article and select the best answer. Article: Recently a friend of mine wrote to me about her experience in Holland: A very old man asked me to come to his apartment, and he would donate a bike to the project. I went over to get it, and it was half a bike, which was locked to a pole and had obviously been there for years. The temperature was well below zero. It became clear that he was in fact super-lonely, and torn between usual Dutch distrust of strangers and desperation for human contact. He finally begged me to come up to his apartment (where he obviously lived alone). You may know that Dutch people are the tallest in the world, reflecting a very high standard of living. But -- if this old man is not unusual -- reducing the loneliness of old people isn't part of the Dutch social contact, admirable as _ may be. I recently watched the Frontline program Sick Around the World. It suggested that the old man isn't unusual. In England, where doctor visits are free, a doctor said he has several patients who come weekly, purely because they're lonely. In Japan, some patients have their blood pressure measured very often -- most probably for the same reason. In Taiwan, if you see a doctor 20 times in one month, someone from the government will come to talk to you. Not about loneliness -- about overuse of medical care. The Frontline program made nothing of any of these facts, which were included to show that access was easy. Really the idea that everyone needs human contact isn't mysterious or controversial. My explanation is there's a double blow: Not only do lonely old people have little power, it's also clear that their problem (loneliness) isn't caused by a "chemical imbalance". So no drugs can be sold to treat it. And there's no diagnostic category. When these lonely old people use what little power they have by visiting their doctor, the doctor -- I'm assuming -- doesn't do anything to get rid of the loneliness. Even if you visit 20 times in a month. Question: The story of the Dutch old man at the beginning of the passage serves as _ . - an example of the lonely people - an important reminder of her friend - an introduction to Dutch social problems - an example of Dutch suspicion of strangers
Answer: an example of the lonely people

Question: Read the following article and select the best answer. Article: It was only a few weeks after my surgery, and I went to Dr. Belt's office for a checkup. It was just after my first chemotherapy treatment. My scar was still very tender. My arm was numb underneath. As usual, I was taken to an examination room to have my blood drawn, again --a terrifying process for me, since I'm so frightened of needles. I lay down on the examining table. Ramona entered the room. Her warm smile was familiar, and stood out in contrast to my fears. She knew about my fear of needles, and she kindly hid the equipment under a magazine. As we opened the blouse, the fresh scar on my chest could be seen. She said, "How is your scar healing?" I said, "I think pretty well. I wash around it gently each day." The memory of the shower water hitting my numb chest flashed across my face. She gently reached over and ran her hand across the scar, examining the smoothness of the healing skin and looking for any irregularities. I began to cry gently and quietly. She brought her warm eyes to mine and said, "You haven't touched it yet, have you?" And I said, "No." So this wonderful, warm woman laid the hand on my chest and she gently held it there. For a long time, I continued to cry quietly. In soft tones she said, "This is part of your body. This is you. It's okay to touch it." But I couldn't. So she touched it for me. The scar. The healing wound. And beneath it, she touched my heart. Then Ramona said, "I'll hold your hand while you touch it." So she placed her hand next to mine, and we both were quiet. That was the gift that Ramona gave me. Question: I began to have the courage to touch the scar _ . - because of Ramona's encouragement - because I could face the fact - because of Ramona's gentleness - because Ramona and I became friends
Answer:
because of Ramona's encouragement
