Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Millions of people visit Yosemite National Park every year to see the tall waterfalls and mountains. These mountains are a splendid sight when viewed from the valley floor. Lots of stores, hotels, and restaurants are needed to handle the crowds. Also, water, roads, and other service systems are part of the infrastructure( )that must be maintained. Unfortunately, these systems are starting to break down. It is not just in Yosemite but in national parks around the nation. Yosemite is thirty years old according to Dennis Galvin, a National Park Service worker. The park is not only old but worn out. Two or three times as many visitors come every year. That is too many visitors for the park to deal with. Four years ago a storm washed out a water pipeline in the Grand Canyon. The National Park Service had to send water trucks to provide water for the visitors. Last month pipe almost broke again and roads had to be closed for a while. Why hasn't the National Park Service kept up the park repairs? There is lack of money. The United States has 378 mountains, parks, and wilderness areas. Between three and four billion dollars are needed for repairs. Yosemite is one national park that does have money fro repairs. It has two hundred million dollars but cannot spend it any way it chooses. When the park workers started widening the road, they were forced to stop by the Sierra Club. The club claimed that the road work was damaging the Merced River that runs through the park. A Sierra Club lawyer, Julia Olson, feels that the infrastructure needs to be moved out of Yosemite. That way less pressure will be put on the already crowed park. Options: A modern water pipes B overcrowdedness C lack of water D narrow roads Answer: B overcrowdedness Question:

A: The main problem of Yosemite Park is its _ .

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: You might not want a holiday in your hometown, but there is probably someone who does. And, in exchange, you could have a cheap vacation anywhere in the world. Just picture the scene: you're watching the sunset from the balcony of a Caribbean island house. It's large. And it's free as long as you don't mind the owners living in your home at the same time. All you need to be a home-swapper is the Internet and a rough idea of when and where you want to go on holiday. When you find someone whose dates match yours, and who wants to visit your area, you're all set to swap. The advantages are numerous: you can save a fortune in accommodation cost. You could get to use the owners' car, boat, bikes, pool or gym. You might even be able to come to an arrangement about looking after each other's pets! You also get to live like a local, and you might be invited around to neighbors' homes for tea, barbecues and tips on the area. People say that these cultural experiences are the memories that last. Plus, instead of one tiny hotel room, you have an entire house where you can make yourself at home. And it's not cold and impersonal like a hotel room. Of course, there are disadvantages. A lot of effort and communication are needed before the arrangements are finalized. Nobody wants a stranger living in their house, sleeping in their bed and using their bathroom, so you have to get to know each other well beforehand. Some people are concerned about theft or property damage, but in reality this is very rare. Most home-exchangers have the view that "If they can trust me with their house, I can trust them with mine." The worse complaint people have is the difference in standards of cleanness. If you're interested in home-exchange for your next holiday, start by contacting a famous agency like homelink.org and intervac,co.uk. These agencies will also have advice about preparing for a home-exchange.
