input: Please answer the following: Write a multi-choice question for the following article: Article: Wind is the great maker of waves. There are exceptions , such as the tidal waves sometimes caused by earthquakes under the sea. But the waves most of us know are caused by winds blowing over the sea . Now let's learn some physical things about it. A wave has height, from low point to high point . It has length --the distance from this high point to that of the following wave. The period of the wave means the time it takes for succeeding high points to pass a fixed point. None of these things stays the same--for all depend upon the wind, upon the depth of the water and many other matters. The water that makes up a wave does not advance with it across the sea. Each drop of water turns around in a little circle with the passing of the wave, but returns very nearly to its original position . And it is lucky that this is so. For if the huge groups of water that make up a wave really moved across the sea, sailing would be impossible. If we want to find the speed of a wave, we may use the following way : Speed =" wavelength" x frequency . Here, wavelength is the distance between two high points , frequency means the number of cycles per second

output: Question: The speed of Wave 1 is 100 cm/s, frequency 10. The frequency of Wave 2 is 300, while its speed is twice that of Wave 1. Which of the following is right?Options:A The wavelengths of the two are equal.B The wavelength of Wave 1 is 10 times longer than that of Wave 2.C The wavelength of Wave 2 is longer than that of Wave 1.D The wavelength of Wave 1 is longer than that of Wave 2.Answer:D

Problem: Given the question: Write a multi-choice question for the following article: Article: Pearl and June were good friends and spent most of their time together. They were both very old and they worried about their health. Most of the time they talked about nothing else. They worried about their food. Was it clean? Would it give them pains in the stomach? They worried about the weather. Was it too cold and wet? Would it give them pains in their bones? They worried about pollution in the air. would it give them pains in their chests and throats? They worried about being hurt in a car accident, killed in a plane crash, getting sick, and so on. All they could think about was being ill or hurt. One day they went on a train journey together. "We'll need some food," Pearl said. "We'll buy some bananas," June said. "They are good to eat and always clean." And so they bought two bananas to eat on the train. It was not long before they were hungry. Pearl took out the bananas and gave one to June. Then she peeled the skin of her banana and took a large bite of it. At that moment the train went into a tunnel. Everything went black. "Don't eat your banana," Pearl shouted at June. "Mine has made me go blind!"

input question: Write a multi-choice question for the following article: Article: Some people have a very poor sense of direction. Unluckily, I am one of them. I have visited a place many times but I may still get lost there the next time. When I was a little girl, I never dared to ask strangers the way. And so I used to walk around in circles and hope that by chance I would get to the place I was going to. Now, I am no longer too shy to ask people for directions, but I often receive helpless or even wrong information. So I try to avoid giving people wrong directions. If anyone ever asks me the way somewhere, I would say, "Sorry, I am a stranger here." Once on my way to work I was stopped by a man. He asked me if I could tell him the way to the Friendship Building. I gave him my usual reply. But just as I walked on only a few steps. I realized that he had asked the way to my office building. However, I had no time to turn back and look for him. I was rushing to meet with someone at my office and I didn't want to keep him waiting. When I just got to my office, the secretary showed in the man who had asked me for directions. Imagine how _ I was and how surprised he was when we saw each other at the first sight.???
