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."

Article: The struggle to "have it all" leaves many mothers giving up their health and hobbies. But dads have more time to spare according to a research, with just 55 per cent saying they lose sleep and regular exercise compared with 71 percent of mums. Twice as many mothers as fathers complained that they did not spend enough time relaxing, with almost half of mums spending less than two hours a week with friends. And more than a third miss out on hobbies and interests because they are too busy. In spite of changing roles in the family, women are still responsible for most of the child care. Nearly a third spend more than 10 hours a week caring for their children, compared with just one in ten fathers. More mums than dads also say housework and tiredness stop them achieving their goals. But the research also shows mums gain a sense of achievement from finishing the housework, getting their children to school on time or sitting down to a family dinner. The research underlines the fact that women feel under pressure to succeed in all areas of their lives. As Nick Booth, a marketing director put, "They are pushing themselves too hard and are in danger of burning out. We'd encourage anyone to take time out for themselves. Having your own interests and hobbies and ensuring you get enough sleep is hugely important. Other parts of your life, including work and family life, improve as a result." The Olympian and mother Jo Pavey admitted balancing career, family and personal time can be a struggle. Jo, 41, became the oldest female gold medalist at the European Championship last year - but regards her children as her biggest achievement. The mum of two said,"When I was younger,I'd have probably said it wasn't possible to have a sporting career and be mum. But actually it is all about striking a balance and looking after yourself."
Question: Which of the following prevents mums from achieving their goals?
Options: (A) Being tired with much housework. (B) Lacking their own interests and hobbies. (C) Looking after their children all the time. (D) Spending little time enjoying themselves.
A

Article: Today in schools, it's not unusual for students to sit in the same kind of desks in the same kind of classrooms as their parents did. Schools have made progress by making use of computers and PDAs in the classroom, yet one design company believes that changes are needed, so they describe what a future classroom may look like. "Kids are being taught to sit at these wooden desks that are basically designed for writing," said Mark Dziersk, the senior vice president of the design. "They're being lectured in a structured environment." The solution is a "customizable education system" called Gooru that reorganizes the classroom and replaces books, desks, pens, and so on. The three-part technology system consists of an interactive PDA called the GooBall, a backpack and a removable LCD screen for each student. Students can sit, stand or lie down when using the devices, and are not limited to desks. The idea was presented at last month's South by Southwest Interactive Conference. While some educators think the idea is interesting, they doubt whether schools will pay for the expensive and complicated system. The GooBall is an interactive communication device with six layers of learning software. The device monitors a student's heart rate and body temperature and uses GPS to track where they are. It includes instant messaging, a compass, a watch, and a topic-specific alert system that directs a student to related articles and books about whatever they are studying. Students can also choose an animal icon to show their personality. The backpack houses the main power supply for the system and holds some personal items. The pocket keeps items locked tight with a fingerprint security zipper. The portable screen functions like a laptop, providing wireless Internet access and streaming video. It also has a touch screen interface. "I think it's an excellent idea," said Gary Tankard, a sixth-grader who has seen the prototype . "I'm sure that 90 percent of kids would really like to have it."
