Write a multi-choice question for the following article, with the given choices and answer: Article: Who would win in a competition to memorize numbers, a chimp or a teenager? The teenager? Think again. Scientists have proved that chimps perform better than human beings when it comes to this kind of problem. We may have to rethink what we believe about human memory. Memory is our ability to learn something, save it and recall it when needed. Our memories are important to our sense of self, our personalities, and our ability to understand the world. Scientists say that there are different types of memory. There is short-term memory and long-term memory. Your short-term memory saves information for a few seconds or a few minutes. For example, the time it takes to compare the prices of a few items in a store. Long-term memory involves the information you try hard to keep, because it's meaningful to you (an example is data about family and friends. ) And then there is visual memory and sound memory. But these are not hard and fast: scientists argue a lot about the nature of memory. Scientists have also found that people memorize things in different ways. Some memorize better with the help of pictures. Others are helped more by sounds. One thing's for sure. If you can combine different kinds of memory together, you will remember a lot! So why not try pictures with English words? At the same time listen to recordings of the same group of words. It may help when it comes to memorizing it. Imagination and association can be useful too. By imagination scientists mean picturing a word in your mind. Association means relating the word to something you already know. Options: A By watching TV. B By listening to music. C By writing them out many times. D By listening and watching pictures. Answer: D By listening and watching pictures. Question:

Write a multi-choice question for the following article, with the given choices and answer: Article: As we all know, the ocean moves. But waves breaking on the beach make the ocean fun. When you stand on the shore and look at the waves, it seems like the water is moving towards you. But the water is not really moving forward. The moving you see is wave energy. And wave energy comes from the wind. Let's think about how this works. As wave energy passes through the water, the energy makes particles of water move up and down. Just give you an example of a wave passing under a basketball. We put a basketball on the sea. When the wind blows, a wave comes from behind the basketball. The basketball moves up to the top with the wave. Then the wave continues and leaves the basketball behind. The basketball looks lower, but it doesn't move forward. That's because the wave energy just moves the water which is under the basketball. So why can you see a wave knock you down on the shore?When a wave moves toward the shore, the bottom of the wave slows down because _ meets the ocean floor. But the top, which is called crest , keeps moving. The different action causes the wave to fall over or break onto the shore. If a wave is very large, it carries a lot of energy when it hits the land. As time goes by, waves can break up and carry away the rocks and other things on the shore. Shorelines are changing all the time because of wave action. Options: A Water B The basketball C Water and wave energy D Wave energy Answer: D Wave energy Question:
