instruction:
In this task, you're given an article, a question which often contains a blank and four options (associated with "A", "B", "C", "D"). Your task is to find the correct answer (from the given options) for the question from the given article and return one of the options from "A", "B", "C", and "D". Do not generate anything else apart from one of the following characters: "A", "B", "C", "D". There is only one correct answer for each question.

Article: Remember, from the moment they are born, our children have the ability to know when they are hungry - and they cry to let us know too! Of course, they also cry to let us know they are wet, hurt, or bored, but we soon learn to tell the difference and try to meet each need somehow. When we begin to feed them solid foods, they let us know when they have had enough by turning away from the spoon - or refusing the food back at us! Why is it that once children are old enough to sit at the table their parents are often heard bargaining with them or threatening them to finish all their dinner? When we make our children eat up the plate that we filled, we don't pay attention to their born ability to know how much, and what, their bodies need. Instead, we should allow them to use their own hunger feelings to determine how much they need, while we provide a balance of nutritious and "fun" foods. When we teach them about moderation and set a great example by living an active, healthy lifestyle, they will be less likely to develop weight problems later in life. Think of your slim friend who eats whatever she wants -but will refuse ice cream if she has had enough to eat! "Eat all your dinner if you want dessert" translates to "you must overeat so I will reward you by letting you overeat some more!" By using sweets as a reward for good behavior, kids begin to believe sweets are really special and they may want them even more. Instead, by making dessert just another (small) part of an enjoyable meal, kids learn to "save room for dessert" instead of becoming a member of the "clean plate club."

question:
Article: A scientist working at her lab bench and a six-old baby playing with his food might seem to have little in common.After all,the scientist is engaged in serious research to uncover the very nature of the physical world,and the baby is,well, just playing...right?Perhaps,but some developmental psychologists have argued that this"play"is more like a scientific investigation than one might think. Take a closer look at the baby playing at the table.Each time the bowl of rice is pushed over the table edge,it falls in the ground---and, in the process, it belongs out important evidence about how physical objects interact ; bowls of rice do not flood in mid-sit, but require support to remain stable. It is likely that babies are not born knowing the basic fact of the universe; nor are they ever clearly taught it. Instead, babies may form an understanding of object support through repeated experiments and then build on this knowledge to learn even more about how objects interact. Though their ranges and tools differ, the baby's investigation and the scientist's experiment appear to share the same aim(to learn about the natural world ), overall approach (gathering direct evidence from the world), and logic (are my observations what I expected?). Some psychologists suggest that young children learn about more than just the physical world in this way---that they investigate human psychology and the rules of language using similar means. For example, it may only be through repeated experiments, evidence gathering, and finally overturning a theory, that a baby will come to accept the idea that other people can have different views and desires from what he or she has, for example, unlike the child , Mommy actually doesn't like Dove chocolate. Viewing childhood development as a scientific investigation throws on how children learn ,but it also offers an inspiring look at science and scientists. Why do young children and scientists seem to be so much alike? Psychologists have suggested that science as an effort ---the desire to explore, explain, and understand our world---is simply something that comes from our babyhood. Perhaps evolution provided human babies with curiosity and a natural drive to explain their worlds, and adult scientists simply make use of the same drive that served them as children. The same cognitive systems that make young children feel good about feel good about figuring something out may have been adopted by adult scientists. As some psychologists put it, "It is not that children are little scientists but that scientists are big children."

answer:
D

question:
Article: Could cities that float on the sea solve the problems caused by floods and provide food for the world? Some scientists think so. The idea is already being tested and they believe that floating citied will provide more homes for a growing population, without having to use land needed to grow food. And they believe floating areas will allow more food to be grown, so that no one in the world is hungry. In some places, cities that float on the sea are already being planned, A company in the Netherlands called DeltaSync thinks that sea cities will save the world, with more than one in ten people living in them. They say sea cities solve many of the problems the world faces in the 21st century, like not having enough land , more and more people needing homes, fossil fuels running low and the increasingly serious problems caused by floods. DeltaSync says building in the desert is not possible because there is no enough water and that developing ways for people to live in space is still too expensive. So they believe the answer is our oceans, which cover over two thirds of the Earth's surface. Their plans for floating areas include using algae to produce fuel and food. More than a quarter of the land in the Netherlands already lies underwater and scientists there have spent years trying to find ways to deal with it. In the city of Rotterdam they already have floating homes. Bart Roeffen from DeltaSync says: "We have plans for neighbourhoods including roads and, in the end, I believe we can build floating cities on the sea."
