Q: Write a multi-choice question for the following article, with the given choices and answer: Article: 66-year-old Dai once worked as a boat tracker along the Yangtze River. "It was something that required brute strength,but not that alone, "Dai said at his home in Xialong village, which sits at the entrance to Wuxia Gorge, one of the famous Three Gorges in Southwest China. "You needed a lot of skills to do what we did." When outboard motors became available in the 1980's,boat trackers became a thing of the past. Today, they are seen only occasionally along the river during festivals and cultural events. However, Dai can still remember a time when being pulled by tracker along the Yangtze was the only way for people to travel from village to village in the mountainous Wushan county. Due to the area's rich mining resources,his services were vital for companies that wanted to ship their goods. "I was 15 or 16 when I started", said the retiree,explaining that his father also worked as a tracker. "He died in 1964, when I was a teenager. I can't even remember us tracking together, but we did. It was so long ago." Dai said that boats crews worked in teams with a first, second and third master. The first master was the most essential because he sat in the boat and steered it along the safest route. "It was a key role. He had to guide the boat past jagged rocks and whirlpools," he said, adding that first masters were often the most experienced boatmen and the most familiar with the Yangtzer River. "My tracker days were dangerous," Dai said. "If the boat got caught in a whirlpool, it could have swallowed the boat and all the trackers down with it. The same thing would have happened if the halter broke." Dai's days as a tracker finally came to an end when his family invested in a motorboat in the early 1980s. He successfully applied for a license from Wushan shortly after. Options: A 66-year-old Dai is a boat tracker along the Yangtze River B being a tracker required more than brute strength C Dai lives at the entrance to Xialong village D Dai is still often seen along the river as a tracker Answer: B being a tracker required more than brute strength Question:

Write a multi-choice question for the following article, with the given choices and answer: Article: Keeping our water pure is by no means an easy task but it is something that must be done. Hong Kong once prided herself on being the "Fragrant Harbour". However, these days, it is not certain if Hong Kong's harbour could still be called "fragrant". For, like many other places, Hong Kong has not been spared water pollution. A visit to Tolo and Victoria Harbour, or any of the beaches in Hong Kong is enough to make one aware of the ugly truth that Hong Kong waters are indeed polluted. The great threat to our water is bacteria pollution. Another great source of water pollution is poisonous chemicals. These substances, which are found in industrial waste and agricultural pesticides, make up unseen dangers that enter biological food chains. Pollution control is a continuing problem for the government. It is believed that the most effective form of control is legislation . Most importantly, the present laws on pollution should be given more force. On the other hand, no amount of legislation can effectively control pollution unless those concerned are properly educated about the danger posed by pollution. While a great majority of Hong Kong citizens and residents seem to be greatly concerned about ways to control water pollution, it is discouraging to note that there are, in our midst, some people who remain apathetic about the problem. In a recent radio programme conducted on what people in the streets thought about the water pollution problem, one apparently unconcerned person said, "What do I care about water pollution? I don't drink polluted water. As long as the water I drink is not polluted, I'm not bothered. Water pollution is too big a problem and let's leave it to the government." If all residents in Hong Kong will take such an indifferent attitude, all the government's attempts to control pollution, let alone the anti-pollution legislation, will prove useless. The best form of pollution control each citizen can employ is to be aware of his surroundings. We hope that someday, the problem of water pollution...
