Article: Imagine sailing through the sky, high above buildings and trees, in perfect peace and quiet. No noisy engines. No window with dirty marks in your way. No strong wind blowing in your face. You can't feel or hear the wind because you're traveling in the exact same direction and at the exact same speed it is. A hot-air balloon has three main parts: the balloon, called an envelope; a basket, where passengers ride; and a burner system, which supplies the hot air. Most balloon envelopes are made of strong, lightweight nylon. They vary in size and shape, but they have to be really, really big to lift even a single person. Most weigh more than an adult man and use more fabric than you'd need to cover a baseball diamond . The basket is usually made of wicker ,which is strong but not too stiff . It needs to bend a bit for a soft landing, just like a good jumper bends her legs instead of keeping them stiff and straight when she lands. When the burner system blasts flames, it makes a noisy sound, but once the balloon is flying , the burner can be turned off. The air in the envelope will then slowly cool, and the balloon will gradually sink unless the pilot starts the burner again. To operate, a pilot adds hot air to the balloon to go up or deflates it to go down, until he finds a breeze blowing in the direction he wants to fly. But no matter which way the wind blows them, balloonists have an amazing bird's-eye view of the world. Question: The text is probably from _ . Yes or no, is the answer "an article on hot-air balloons in an airplane magazine"?

Article: Imagine being bald and walking into class at school. You escape to the back row but see other students pointing at you and talking about you. You feel embarrassed. After school, you run home to avoid talking to anyone. Some medical problems cause people to lose their hair. This can be embarrassing for adults, but for children it is even worse. They often feel bad about themselves, and other children laugh at them. In her 20s, Madonna Coffman developed alopecia, a skin disease that causes hair loss. She recovered after a few years, but 15 years later, her 4-year-old daughter developed alopecia. Her daughter's feelings encouraged Coffman to make Locks of Love a non-profit organization. Locks of Love provides hairpieces for children who lose their hair for medical reasons. Children from poor families receive hairpieces for free or at prices their families can afford. The organization hopes to increase the children's confidence and help them enjoy a more normal life. The hairpieces are made of hair donated by ordinary people. They grow their hair long, cut off at least 10 inches of it and mail it to Locks of Love. Locks of Love then sends the hair to the company that makes hairpieces. The organization says that 80% of those who give their hair are children who want to help other children. The hairpieces are easy to wear and fit the wearer's head very well. No one except the children who wear the hairpieces can take them off. This lets the children run, play and swim without worrying about the hairpiece falling off. And other children won't be able to pull the hairpiece off either. These hairpieces do more than change how the children look. They help kids to enjoy their childhood. The children can join in activities, make friends and face each day with confidence. Locks of Love allows kids to be kids again. Question: According to the text, the hairpieces are _ . Yes or no, is the answer "comfortable and safe"?
No

Article: There is no doubt that music plays a powerful role in our lives. It can calm our tired nerves after a busy day of work. Music even has the power to move us to tears when it stirs an emotional reaction. How then, does music play a role in special education? If music has the ability to touch those hidden places we all carry inside, it proves an important tool for the special education teacher. For students with emotional problems, music can help soothe sadness. Consider the child that arrives in class depressed and upset. If music can indeed relax and calm him, he is more likely to focus and participate in class. Dr. R. Joseph, author of Behavioral Neurology, writes, "It is well recorded that patients with left hemisphere damage, who may be unable to speak or recognize words, can sing a melody ." For this reason, some special education teachers have found it helpful to set their lessons to music. When students cannot understand or remember certain things, singing them helps make it easier. Nature magazine reported "Music training helps underachievers. In Rhode Island, researchers studied eight public school first grade classes. Half of the classes became 'text-arts'groups, receiving ongoing music training. After seven months, the students were given a test. The tested group had caught up with their fellow students in reading and surpassed their classmates in math by 22 percent. In the second year of the project, the tested students widened this even further. Students were also tested on attitude and behavior. Classroom teachers also noted improvement in these areas." It seems music does, indeed, play an important role in education. For the special education teacher, this is especially encouraging. Question: What is the text mainly about? Yes or no, is the answer "The role of music in special education"?
