Write a multi-choice question for the following article, with the given choices and answer: Article: When does music in public places become noise pollution? You may like at least some kind of music. But the problem is that, in lots of places, you're made to hear somebody else's choice in music. Say you've just landed at an airport. At the airport, the "background" music may be played loudly. When you are on the way to your hotel, there may be another kind of music played by the taxi driver. Then you finally reach your hotel. But when you are taking the elevator ,there is elevator music. You go out to dinner and end up in a place where the owner of the restaurant thinks music will help make you eat more and spend more. Then a person playing the violin comes around. This is called the "music wallpaper". It is to make you buy more and eat a lot. Even the government thinks this is "noise pollution," especially when the music is too loud. Noise pollution may be bad for our hearing. It's also bad for some of our daily activities, such as sleeping, conversations and so on. The fact that you can't see, taste or smell it may help explain why it has not received as much attention as other kinds of pollution, such as air pollution or water pollution. The air around us is always filled with sounds, but most of us would not think we are surrounded by noise. This can be bad for our health. So many people like soft and quiet music in their house. Options: A music that is too loud is bad for our health B people pay as much attention to noise pollution as they do to air pollution C people like loud music in their house D most people think that there's lots of noise around us Answer: A music that is too loud is bad for our health Question:

Write a multi-choice question for the following article, with the given choices and answer: Article: American nutrition expert Professor Barry Popkin says that the number of overweight people in the world is now bigger than the number of people who don't have enough to eat. A billion people worldwide now weigh too much and the number of obese people is now more than 300 million. "Obese" means at least 15 kilos heavier than you should be. However, there are also 800 million people in the world who don't have enough to eat. Professor Popkin says that the number of hungry people is falling slowly but the number of overweight people is rising fast. The main reasons for this are: * People are doing less hard physical work * More people worldwide now eat too much fatty food * Too many people are driving cars instead of walking * People spend too much time in front of a television The United States has the highest rate of obesity in the developed world and Japan has the lowest. Professor Benjamin Senauer is absolutely certain of the reasons for this. "Japanese people are fit. They use public transport and walk," he said.

"The effects of this are clear," said London doctor Elena Power. "We have more illnesses related to weight and fewer fit people. China used to be one of the slimmest nations in the world.
