In 1992, the people of the town decided to restart some long-forgotten traditions. Back in the late 1800s, there was a robber called Rosvo-Ronkainen in that area. He was said to only accept men as members of his gang who proved their worth in challenges. At that time, it was also a common practice to steal women from neighboring villages. This event is becoming increasingly popular. A large number of competitors, people, and journalists from Finland to Canada attend the Wife-carrying World Championship every year. The event is famous for its warm and humorous atmosphere. The Wife-carrying World Championship is held on a 253.3 meters long official track. The track has two dry obstacles and a water obstacle, about a meter deep. There are a few basic rules and the winner is the couple who complete the course in the shortest time. The wife to be carried may be your own, or your neighbor's. The minimum weight of the wife to be carried is 49 kg. If she is less than 49kg, the wife will be given a heavy bag to carry. Each time a competitor drops his wife, that couple will be fined 15 seconds. Alongside with the Wife-carrying World Championship, there is also a team competition. The distance is the same but three men in the team carry the wife in turns. At the exchange point the carrier has to drink official "wife-carrying drink". Then he may continue the race. A special prize is awarded to the team with the best costumes. While the Wife-carrying World Championship is being held, there are bands playing music, a wife-carrying dance and other forms of entertainment. Question: If a husband drops his wife 3 times in the competition, he will be fined _ . Options: A: 15 seconds B: 30 seconds C: 45 seconds D: 60 seconds

Read the article and select the best answer. Article: Global warming happens when greenhouse gases trap heat and light from the sun in the earth's atmosphere, which increases the temperature. This is like when heat is trapped in a car. On a hot day, the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car, by going through the windows,but it can't get back out. This is what the greenhouse effect does to the earth .The heat and light can get through the atmosphere, but it can't get out As a result,the temperature rises. Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on Without _ ,the earth would be freezing,or it would be burning hot. It would be freezing at night because we would not get the sun's heat and light .During the day, especially during the summer, it would be burning because the sun would be up with no atmosphere to filter it,so people,plants,and animals would be exposed to all the light and heat. Although the greenhouse effect makes the earth able to have people living on it,if there gets to be too many gases,the each can get unusually warmer, and many plants,animals.and people will die. Plants would die because they would not be able to take the heat .This would cause us to have less food to eat, and it would also limit the food that animals have. With less food for the animals that we need to survive we would even have less food. Gradually, people,plants,and animals would all die of hunger. People are doing many things to try to stop global warming .One thing is carpooling--driving with someone to a place that you are both going to. Another thing is being more careful about leaving electrical devices turned on. Now, more people are even riding buses or bikes to lower the amount of greenhouse gases in the air .Although adults do many things to help stop global warming, kids call do just as much. Question: What is the effect of atmosphere? Options: A: IT only traps the heat of the sun. B: It does great harm to humans. C: It makes the earth neither to hot nor too cold.
