Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: 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 Options: A The water of a wave moves away across the sea. B The water of a wave remains almost at the same place. C The water of a wave goes with the passing of the wave. D The length of a wave means the distance from the top of a wave to the bottom. Answer: B The water of a wave remains almost at the same place. Question:
