Article: Three men were travelling across the desert when their car broke down. There were no other traffics, so their only hope was to walk. Before they set off, they looked around in the car for useful things to take with them. One of the men took a bottle of whisky. Another took an umbrella. The third unscrewed a door from the car and carried that. After they had been walking for almost a day, they came across a camel caravan travelling towards them. "Let's try to join the caravan," one of the men said. "It's going the wrong way but we'll be safer than if we keep on alone across the desert." The other s agreed, so they asked the leader of the caravan for permission to join it. "You can join the caravan only if you answer three questions," he said. He pointed to the first man's bottle. "What is that and why are you carrying it?" he asked. "It's a bottle of whisky. I decided to carry it with me so that if I feel miserable and want to give up, I can get drunk, cheer myself up and then keep on walking." "Very sensible," the leader of the caravan said. Then he pointed to the next man and his umbrella. "It hasn't rained in the desert for many years," he said. "Why are you carrying an umbrella?" "I don't want to get heat exhaustion," he replied. "The umbrella will give me shade from the sun." "Very sensible," the leader of the caravan said. He pointed to the third man and his car door. "And why are you carrying a car door?" he asked him. "I thought that if I got too hot I could open the window and let some air in," he explained.
Answer: They exchanged it for another one.
What happened to the three men's car?

Article: Among a group of middle-aged men and women,who were discussing bringing about quality education ,was a young man dressed in a white shirt.Within minutes, he was called onto the dais .Twenty-two-year-old Babar Ali was surrounded by educators from across India.He was popularly known as the world's youngest head teacher. The school that Babar started in poor Bhabta village has completely changed.When he was nine years old, he had only eight students in his school.Now the school has 300 students and 10 teachers. The school is called Ananda Siksha Niketan. It is recognized by the West Bengal government. Today Babar is a student in the morning.He is learning English literature at Berhampore Krishanath College.But he comes home in the afternoon to teach his students. Baber was discussing education at the National Summit on Quality in Education(NSQE).The meeting was held in Bangalore,capital of Karnataka State in southern India. "It all started as a game when I used to teach my sister, my first student, in my backyard.Later, some children from the village often came to my classes and that was how the school was born," he said. His biggest achievement is that six of his students have now started teaching in his school after their college hours. In another month, Babar's dream of a school building will soon come true.Many people, a large part of whom are from Karnataka,have helped him realize the dream.They have given his school a lot of money. Although he has received so much attention and recognition ,he is still not _ ."There are people in my village who do not go to schoo1.And there is a long way to go as so many children still need to receive an education,"he says.
Answer: At an important meeting.
Where were Babar and a group of middle-aged people?

Article: It is 7 o'clock in the morning. You check yourself in the mirror, adjust your collar, and consider the busy day ahead. But at least you know that the stress won't damage your health, for this is no ordinary set of clothes you are wearing. Set within the fabric are numerous sensors, constantly monitoring your vital signs. If danger signs are detected, the garment is programmed to contact your doctor and send a text message telling you to take it easy. Garments that can measure a wearer's body temperature or trace their heart activity are just entering the market, but the European project BIOTEX weaves new functions into smart textiles. _ biosensors in a textile patch can now analyse body fluids, even a tiny drop of sweat, and provide a much better assessment of someone's health. Jean Luprano, a researcher at the Swiss Centre for Electronics and Microtechnology (CSEM), coordinates the BIOTEX project. "One of the most obvious applications for smart fabrics is in the medical field," he says. "There has been a good deal of progress with physiological measurements, body temperature or electrocardiograms . But no one has yet developed biochemical sensing techniques that can take measurements from fluids like sweat and blood. We are developing a suite of sensors that can be integrated into a textile patch. The patch is a sensing and processing unit, adaptable to target different body fluids and biochemical species. At the very least, some basic biochemical analyses could complement the physiological measurements that can already be monitored. In some circumstances, fluidic analysis may be the only way to get information on a patient's health status."
Answer: New advancement in the medical field.
