[Q]: 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.

[Q]: Article: Controlling traffic is a complex and high cost problem in many developed countries. It becomes more difficult and costly with the ever- increasing number of cars on the roads. But scientists and students at the CATT, at the University of Maryland are working to solve this problem. They are using simulation technologies to help government and private business control and react to changing traffic conditions. The online economics magazineForbes.comsays traffic congestion cost Americans $ 124 billion in 2014 and that number could rise to $ 186 billion by 2030. Bui scientists at the CATT lab are trying to reduce those costs. They are developing a system that helps traffic managers. planners, emergency workers and businesses plan and react better. Michael Pack is CATT director. He says the system is important to help emergency workers, or first responders,reach an accident area faster. The CATT Lab collects information from many sources, including roadside devices, GPS (global positioning system) equipment and wireless phones. About 60 students and 30 software developers observe traffic flow and manage the computer servers at all times. They also work to develop software and applications that can help traffic run smoother and safer, Some of them turn the information gathered into so-called "visualizations". These visual representations help emergency workers better understand what is happening. The center shares its findings with firefighters, police,Transportation departments and the military. They also share information with universities and transportation company. The technology company Google uses the data for its traffic-related websites. Michael Pack says, the information is then shared with anyone who wants to help traffic run more smoothly. Mr. Pack says the goal is to help develop an intelligent system of road signals that will communicate with each other and with vehicles on the road.
