Q: I'm taking a test and have to guess the right answer to the question after the article. Article: They may be small, and unable to have an adult conversation, but babies are proving their collective cleverness. While your baby still might not be able to speak, he or she knows about you're feeling down. Babies as young as 5 months of age can distinguish an exciting tune from a sad one, according to a study published in 2014 in the journalNeuron. Speaking of music, it seems that babies can't resist it. Not only are their ears sensitive to the beats, babies can actually dance in time to them, according to a study published in 2010. To test their dancing ability, the researchers played recordings of classical music and speech to them, and videotaped the results. The babies moved their arms, hands, legs, feet, and heads much more in response to the music than to speech. The findings suggest this dancing ability is innate in humans. Babies can apparently learn even while asleep. As newborn babies spend most of their time sleeping, this newfound ability might be crucial for them to adapt rapidly to the world around them, and help ensure survival, the researchers say. The study was published in the journalProceedings of the National Academy of Sciences. Deciding whether another person is helpful or harmful is crucial in choosing friends -- and that ability starts being visible early. Kiley Hamlin of Yale University showed both 6- and 10-month-olds some anthropomorphized shapes, in which one shape helped another climb a hill, while a third shaped pushed the climber down. The little ones then got to choose which shape they preferred. For both age groups, most babies chose the helper shapes. This character-judging ability could be the first step in the formation of morals, Hamlin says. Question: Kiley Hamlin found that babies _ . Options: A: love to make friends B: learn nothing while asleep C: can tell right from wrong D: like watching anthropomorphized shows
A: C

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Why are we addicted to upgrades? According to Donald Norman, American author of the book The Design of Everyday Things, "planned obsolescence" is the trick behind the upgrading culture of today's consumer electronics industry. The New York Times cited Norman last month, saying that electronics manufactures strategically release new upgrades periodically, both for hardware and software, so that customers on every level feel the need to buy the newest version. "This is an old-time trick- they're not inventing anything new," he said. Thomas Wensma, a Dutch designer, despises the "planned obsolescence" of companies, as recently reported by UK-based The Guardian. Wensma said this is a wasteful system through which companies - many of them producing personal electronics - release shoddy products simply because "they know that, in six months or a year, they'll put out a new one". But the new psychology of consumers is part of this system, as Wensma said to the newspaper: "We now want something new, something pretty, the next shiny thing." _ "It's to the damage of the consumer and the environment," as the New York Times quoted Norman. "But perhaps to the betterment of the stockholder." In its most recent fiscal year, Apple's profit margin was more than 21 percent, reported the Los Angeles Times. At Hewlett-Packard, the world's biggest PC manufacturer, it was only 7 percent. "Steven Jobs pushed the principle of 'planned obsolescence' to new heights," the newspaper commented on the company's profits and marketing strategy. "Apple's annual upgrades of its products generate sales of millions of units as owners of one year's MacBook or iPhone line up to buy the newest version, even when the changes are incremental." Peer pressure As to Li Jijia, the need for upgrading his smart phone comes mainly from friends and classmates. When the majority of friends are switching to the latest devices, he worries about feeling left out. "Some apps and games require better hardware to run," said Li. "If you don't join in, you lose... Question: The writer takes the example of Li Jijia to show that _ . Options: A: the new psychology of consumers is also to blame for the wasteful system B: young people are always fond of something new, pretty and shiny C: if you don't upgrade your smart phone, you will lose contact with your friends D: needs of consumers help to promote the development of electronics industry
