[EX 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.

[EX Q]: Article: In the Arctic Ocean waters live the social animals---belugas, which is also known as white whales. Highly intelligent, these whales use different sounds to communicate and find their way. Belugas are also among the smallest kinds of whales. More than 210 belugas, including 31 in the United States, live in aquariums around the world. The Georgia Aquarium has asked for permission to bring 18 more belugas into the U.S. The whales were caught off the coast of Russia. The National Oceanic and Atmospheric Administration (NOAA) is considering the aquarium's request thoroughly. A law called the Marine Mammal Protection Act (MMPA) says the animals can only be brought into the country and put on display if they are caught without being hurt and there is an educational reason for doing so. Georgia Aquarium officials say the 18 belugas will help people learn more about the species and allow scientists to better understand how to protect it. The aquarium would also breed the whales so the U.S. aquariums can continue to display them. "When we can study and observe, we gain a better understanding of their biology and diseases that affect them, and learn how to aid populations in their natural habitats," says William Hurley, Georgia Aquarium's chief officer. "Much of this research would be impossible in the remote locations and extreme climates where the animals live." The Georgia Aquarium would own the 18 belugas and would rent some to aquariums across the country. Meanwhile, many scientists, including Lori Marino, a whale expert, feel strongly that the whales belong in the ocean, not in tanks. These scientists say the whales are being used for entertainment and not for education, and having them in aquariums is not necessary for the species to survive. Marino said, "Not only is it unfair to the belugas but there is no educational value in putting these whales on display."
Answer: They are the smallest in number.
