Article: Music comes in many forms; most countries have a style of their own. The US is well known for jazz , which has gained world-wide popularity. In contrast to classical music, which follows formal European traditions, jazz is natural and free-form. It is full of energy, expressing the moods, interests, and feelings of the people. It has a modern sound that makes people very excited. In the 1920s jazz sounded like America. And So it does today. The origins of this music are as interesting as the music itself. Jazz was produced by American blacks, who were brought to the Southern States as slaves. They were sold to plantation owners and forced to work long hours in the cotton and tobacco fields. This work was hard and life was short. When a Negro died, his friends and relatives formed a group to carry the body to the cemetery. A band often went with them. On the way to the cemetery the band played slow and sad music. But on the way home the mood changed. _ Everybody was happy. Death had removed one of their members, but the living were glad to be alive. The band played happy music, which made everyone want to dance. It was an early form of jazz. Music has always been important in their lives. Coming mainly from West Africa, the black men who were brought to America already possessed a rich musical tradition. This music centered on religious ceremonies in which dancing, singing, clapping and stamping to the beat of a drum were important forms of musical expression. As these people settled in to their fields, they made up work songs. Singing made the hard work go faster. Another musical form that helped to develop jazz was the blues. Blues songs always describe something sad -- an unhappy love affair, a money problem, bad luck. To this day, the expression "feeling blue" means being sad. Question: Why did the band play happy music on the way home from the cemetery? Yes or no, is the answer "Because they were glad that they themselves were still alive."?

Article: Travel is exciting and summer is a busy period for holiday travel. Many people will travel great distances in airplanes, cars or other vehicles. Experts say people should know about other health problems that can strike when traveling by air. One of these is a condition called hypoxia . It results from a lack of oxygen to the brain. Experts say the body begins losing oxygen minutes after an airplane leaves the ground. The air pressure in a plane during flight is lower than at sea level. This makes it more difficult for the body to effectively use the same amount of oxygen as it would on the ground. Fewer oxygen molecules cross the tissues in the lungs and reach the bloodstream. The result is a five to twenty percent drop in the amount of oxygen in the blood. This reduces the amount of oxygen that reaches the organs of the body. One effect of this lack of oxygen to the brain is a headache. When this happens, the heart attempts to _ by beating harder and faster. This can make the traveler feel tired. These signs of hypoxia are not dangerous in a healthy person. But a drop in oxygen level can cause a health emergency in people with heart or lung problems. They might lose consciousness or even suffer a heart attack. Experts say that smoking cigarettes and drinking alcoholic liquids also reduce the body's ability to use oxygen. So they suggest that people not drink alcohol or smoke cigarettes either before or during a flight. They also say persons with heart or lung problems should seek advice from their doctors before flying. Question: The author writes the passage mainly to _ . Yes or no, is the answer "explain the causes and effects of hypoxia"?

No

Article: Many of us feel uneasy when someone stands too close to us, talks to us too loudly or makes eye contact with us for too long. But have you ever wondered why those things make you uncomfortable? It's all about personal peace, which means not only an imaginary space around the body, but also the space around all the senses. People feel that their space is being violated when they meet with an unwelcome sound, smell or look. This is probably why a man on a crowded bus shouting into his mobile phone or a woman next to you putting on strong perfume makes you feel angry. Whether people have had a stronger wish to protect their personal space in recent times is hard to say. Yet studies of airlines show that people have a strong desire to have space to themselves. In a survey by Trip Advisor, a travel website, people said that if they had to pay more for some extra service, they would rather have larger seats than extra food. Although people may need their personal space, some hardly realize it. For example, people on a bus who hold newspapers in front of their faces to read in fact keep a distance from strangers. Go and watch a library table. You will notice that one of the corner seats will usually be taken first, because they are the farthest way. What if someone sits opposite to you? Maybe you will pile up books as if to make a wall. Preference for personal space are different from culture to culture. Scientists have found that Americans generally prefer more personal space than people from other cultures. In Latin cultures, however, people are more comfortable standing close to each other. Question: Who might feel his personal space is safe according to the passage? Yes or no, is the answer "A Latin boy who is chatting with a friend sitting close to him."?

Article: A new system that scans customers' fingerprints and subtracts the grocery bill from their bank accounts has taken supermarkets in Germany to use the new system. "Almost a quarter of our customers pay with their fingers," said an employee at the headquarters. Edeka has tried the system at 70 of its supermarkets. It says it will introduce it at 200 others because customers like it. "At first we thought that only the young who really keep up with the latest technology would be interested, but we were wrong," said Stefan Sewoester from IT Werke. "Almost two-thirds of the people who use the system are 40 and older," he said. IT Werke, a computer company, is one of the pioneers of fingerprint payment software in Germany. It has helped about 150 shops, canteens and bars to put in the fingerprint scanning machines. Each costs about 2,000 euros. To sign up for the service, customers must have their fingerprints taken and leave their addresses and banking details with the shop. The shop then takes the cost of goods directly out of the customer's bank account. "It is especially a good thing for elderly people. Now they do not have to remember their pin to pay with their bank cards, or to scratch around for their glasses or cash." Sewoester said. The stores benefit from the system too. It saves more than time in the check-out line. It also cuts out the hidden costs of accepting electronic card payments. Question: According to the passage, the fingerprint system _ . Yes or no, is the answer "has caused payment revolution in Germany"?
