Please answer this: Write a multi-choice question for the following article: Article: Rivers are one of our most important natural resources . Many of the world's great cities are located on rivers, and almost every country has at least one river running through it that plays an important part in the lives of its people. Since the beginning of history, people have used rivers for transportation. The longest one in the United States is the Mississippi. The lifeline of Egypt is the Nile. To the people of India, the Ganges is great, but it is also important for transportation; ships can travel along it for a thousand miles. Other great rivers are the Congo in Africa and the Mekong in southeastern Asia. The greatest of all for navigation , however, is the Amazon in Brazil . It is so wide and so deep that large ships can go about two thousand miles up it. Besides transportation, rivers give food to eat, water to drink, water for crops, and chances for fun. In order to increase the supply of water for crops, engineers sometimes build a dam across a river and let a lake form behind the dam. Then people can use the water not only to irrigate their fields but also to make electricity for their homes and industries. However, large cities and industries that are located on rivers often cause problems. As the cities grow in size and industries increase in number, the water in the rivers becomes polluted with chemicals and other materials. People are learning the importance, however, of doing more to keep their rivers clean if they want to enjoy the benefits of these natural resources.

Problem: Write a multi-choice question for the following article: Article: BEING an astronaut sounds cool, doesn't it? In space, they get to do some pretty amazing things, like floating in zero gravity . However, there are also plenty of things that astronauts can't do because of their weightless environment, and that's very sad. What's worse, they can't even let their sadness show, because it's impossible to cry in zero gravity. Of course, astronauts can still produce tears . But crying is much more difficult in space, according to The Atlantic in January. Without gravity, tears don't flow down out of the eyes like they do here on Earth. This means that when you cry in space, your tears have nowhere to go -- they just stick to your eyes. In May 2011, astronaut Andrew Feustel experienced this during one of his spacewalks. "Tears," he said, "don't fall off of your eyes. They just stay there." Besides making your vision unclear, this can also cause physical pain. Back on Earth, tears are supposed to bring comfort to the eyes. But that's not the case in space. The space environment dries out astronauts' eyes, and when tears suddenly wet the eyes, it can cause pain rather than comfort. "My right eye is stinging like crazy," Feustel told his teammate during the walk. Since gravity doesn't work in space, astronauts need some extra help to get rid of the tears. Feustel chose to rub his eyes against his helmet to wipe the tears away. Another choice is to just wait -- "When the tears get big enough, they simply break free of the eyes and float around," astronaut Ron Parise told The Atlantic. There are lots of small things -- things like crying -- that we are so used to on Earth. We usually _ until they become a problem in a totally different environment, like space. There, astronauts can't talk to each other directly. They also can't eat or drink in normal ways. They can't even burp , because there is no gravity to hold the food down in their stomach. If they do burp, they just end up throwing up everything in their stomach, according to the UK National Space Center. Therefore,...

input question: Write a multi-choice question for the following article: Article: To: manager@tastytreat.com Date: Monday, 7th October, 3:34 p.m. From: raymondyuen@canada.net Subject: Complaint Dear Mr. Price, I have eaten in your restaurant many times and have always been happy with the food and service. This makes what happened last Saturday even more disappointing . It was my son's birthday so we booked a non-smoking table at your restaurant for 7:30 p.m. We arrived on time but were told that our table was not yet ready. At 8:00 p.m., we were given a table in the smoking area. I asked to move but I was told that there were no other tables. A lot of people were smoking so it was uncomfortable and unhealthy. Our first waitress, Janet, was very polite and helpful. She gave us free drinks for waiting so long. Our food also came quickly and looked fresh and tasty. When my wife had eaten most of her meal, she found a dead cockroach in her vegetables. She was shocked and wanted to leave. At first, the waitress told us it was a piece of garlic .When we told her it had legs, she apologized (="said" sorry) and took the food away. We asked for the pay for my wife's meal bill, expecting not to pay for my wife's meal. Nobody came. After 15 minutes, I asked to see the manager. The headwaiter told us that you were on holiday. I complained again about the horrible cockroach. He told me Janet had finished work. He didn't believe my story and gave me a bill for three meals. I argued with him but was forced to pay. The waitress, Janet, was always friendly, but I would like an apology from your impolite headwaiter and a full refund for our meal. It cost $68. Until then, I will not be eating at your restaurant or recommending it to anyone. You can contact me at 742-3254 or through e-mail if you want more information. Thank you for your attention. Yours sincerely, Raymond Yuen???
