Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings. The noise that affects sea animals comes from a number of human activities. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves. Decibels measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land caused pain to human ears. In water, a decibel level of one hundred and ninety-five would have the same effect. Some scientists have planned to set a noise limit of one hundred and twenty decibels in oceans. They have found that noises at that level can frighten and confuse whales. A team of American and Canadian scientists discovered that loud noises can seriously hurt some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales' ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected. Many researchers whose work depends on ocean sounds disagree to a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research. Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists suspect that noise is a greater danger than they believed. They want to stop noises from harming creatures in the ocean. Options: A They are deaf because of noises. B Noises at a certain level may hurt them. C They are easily confused by noises. D Noises will limit their ability to reproduce. Answer: B Noises at a certain level may hurt them. Question:

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Are you a gourmand ? Do you want to eat every delicious food in the world? Then do you watch the popular program?"A Bite of China " is a documentary on Chinese delicious food which has been broadcasted by Chinese central television. Is there any holiday that isn't celebrated with a special festival food? Here are several traditional Chinese foods: Eggs hold a special meaning in many cultures, and China is no exception . The Chinese believe eggs mean producing something new. After a baby is born, parents may hold a "red egg and ginger party," where they pass out eggs to announce the birth. In some areas of China the number of eggs represents the sex of the child, for example, an even number(1,3,5,---) for a girl, and an odd number(2,4,6---) if a boy has been born. Noodles are a symbol of longlife in Chinese culture. They are as much a part of a Chinese birthday celebration as a birthday cake with lit candles is in many countries. Since noodles represent long life, it is considered very unlucky to cut it off. Although westerners sometimes may be very sorry to see fish lying on a plate, in China a whole fish is a symbol of richness. In fact, at a party it is traditional to serve the whole fish last, pointed toward the valued guest. Fish also has a special meaning because the Chinese word for fish, yu, sounds like the word for richness or plenty, and it is believed that eating fish will help your wishes come true in the year to come. A very popular dish during the Dragon Boat Festival is Zongzi. This tasty dish is made of rice dumplings with meat, peanut or other delicious food in bamboo leaves.
