Question: Article: What is your earliest childhood memory? Can you remember learning to walk? Or talk? The first time you watched a television program? Adults seldom call back events much earlier than the year or so before entering school, just as children younger than three or four seldom remember any specific, personal experiences. A variety of explanations have been suggested by psychologists for this "childhood amnesia". Now Annette Simms, a psychologist of Riverdale University, offers a new explanation for childhood amnesia. According to Dr. Simms, children need to learn to use someone else's spoken description of their personal experiences in order to turn their own short-term, fast forgotten impressions of them into long-term memories. In other words, children have to talk about their experiences and hear others talk about them. Without this verbal reinforcement , children cannot form permanent memories of what they have experienced. So why should personal memories depend so heavily on hearing them described? Dr. Simms presents evidence that the human mind organizes memories in that way. Children whose mothers talk with them about the day's activities before bedtime tend to remember more of the day's special event than those whose mothers don't. Talking about an event in this way helps a child to remember it. And learning to organize memories as a continuous story is the key to a permanent mental "autobiography " of important life events. Dr. Simms suggests that we humans may be biologically programmed to turn our life experiences into a novel. The key to creating this mental life story is language, says Dr. Simms. "Children learn to talk about the past," she says. "Talking to others about their short-term memories of the past leads to the establishment of long-term memories." One way it does this is by helping a child to recognize that the retelling of an experience is just the experience itself, recreated in the form of words. The child learns that this "word-description" of an experience can then be stored in... Question: According to Dr. Simms, the reason why children don't form long-term memories before the age of three is that children _ . Yes or no, is the answer "haven't developed enough language skills"?
Answer: No

Question: Article: Robots make me nervous--especially the ones which seem to think for themselves. I was embarrassed to admit this till I heard that Bill Gates, the founder of Microsoft, felt the same way. Gates said in an interview with the social networking and news website Reddit: "I am in the camp that is concerned about super intelligence. First the machines will do a lot of jobs for us and not be super intelligent.That should be positive if we manage well. A few decades after that though the intelligence is strong enough to be a concern." Well, maybe I don't have to worry about my computer and kitchen equipment yet. After I use them I can always pull the plug. But in the future, machines might find a way to prevent us from switching them off. There's a terrible thought! Maybe the problem with computers too clever for us is not that they are evil like some we've seen in sci-fi movies. What could put us in danger is that they might be too efficient. That's what philosopher Nick Bostrom from Oxford University believes. He says that machines are indifferent to humans and in pursuit of their own goals,the destruction of people might be just additional damage. Bostrom gives us an example: A machine which might have as its only goal to produce as many paperclips as possible might look at human bodies as extra material for paperclips and go after you. Because it is, well, a machine, it would not take pity on you. It's a good thing that American writer Isaac Asimov thought about how far robots can go and left us his three rules of robotics. They state that a robot may not hurt a human being or allow the human being to come to harm. I'm glad my machines at home are "dumb". All my cleaner wants to take over is the carpet in my living room. Let's hope they don't create an appliance which wants to take over the world!. Question: What does the text mainly focus on? Yes or no, is the answer "The concern for super intelligence."?
Answer: No

Question: Article: I usually doubt about any research that concludes that people are either happier or unhappier or more or less certain of themselves than they were 50 years ago.While any of these statements might be true, they are practically impossible to prove scientifically. Still, 1 was struck by a report which concluded that today's children are significantly more anxious than children in the 1950s. In fact, the analysis showed, normal children between 9 and 17 have a higher level of anxiety today than children who were treated for mental illness 50 years ago. Why are America's kids so stressed? The report cites two main causes: increasing physical isolation brought on by high divorce rates and less involvement in community, and a growing perception that the world is a more dangerous place. Given that _ , adults can still do plenty to help the next generation to cope. At the top of the list,nurturing is a better appreciation of the limits of individualism. No child is an island. Strengthening social ties helps build communities and protect individuals against stress. To help kids build stronger connections with others, you can pull the plug on TVs and computers. Your family will thank you later.They will then have more time for face-to-face relationships, and they will get more sleep. Limit the amount of virtual violence your children are exposed to. It's not just video games and movies; children see a lot of murder and crime on the local news. Keep your expectations for your children reasonable. Many highly successful people never attended Harvard or Yale. Make exercise part of your daily routine. It will help you deal with your own anxieties and provide a good model for your kids. Sometimes anxiety is unavoidable,but it doesn't have to ruin your life. Question: What does the author thinks of the conclusion that people in America are unhappier than 50 years ago? Yes or no, is the answer "Questionable"?
Answer:
No
