Question: Article: There is a growing problem of what to do with electronic waste such as old televisions, computers, radios, cellular telephones and other electronic equipment. Electronic trash, or e-waste, is piling up faster than ever in American homes and businesses. People do not know what to do with old televisions or computers, so they throw them in the trash. National Solid Wastes Management Association (NSWMA) state programs director Chaz Miller says the large amount of electronic waste Americans produce is not unexpected. The US Environmental Protection Agency (EPA) estimates more than 400 million consumer electronic items are dumped each year, and there is a push by more states to ban the waste from landfills and create recycling programs. They can be torn apart and sorted for useable parts. Mike Fannon who runs the plant in Baltimore, says, "There are a lot of valuable metals that can be recovered and reused instead of just putting them in the landfill, and in certain components, there are some materials that should not really be in the landfill," Fannon explains. Fannon says nearly 20 percent of electronic waste is recycled nationwide. Thirteen years ago, it was only about 6 percent. Recycling rates continue to rise as more communities have banned electronics from landfills in an effort to keep e-waste poisons like lead and mercury out of garbage dumps. This year, several states like Vermont imposed a ban on electronic waste in landfills. More than 25 other states have also adopted landfill bans, e-waste recycling programs or both. Chaz Miller says more can be done to boost electronic waste recycling. "We can do much better," noted Miller. "I think clearly our goal should be to do as well as we do recycling newspapers."
Answer: Old newspapers.

Answer: Which of the following does NOT belong to e-waste?

Question: Article: Below is a selection from a popular science book. If blood is red, why are veins blue? Actually, veins are not blue at all. They are more of a clear, yellowish colour. Although blood looks red when it's outside the body, when it's sitting in a vein near the surface of the skin, it's more of a dark reddish purple colour. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison. Which works harder, your heart or your brain? This question depends on whether you're busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But, in the long run, your brain probably tips it, because even when you're sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it. Do old people shrink as they age? Yes and no. Many people do get shorter as they age. But, when they do, it isn't because they're shrinking all over. They simply lose height as their spine becomes shorter and more curved due to disuse and the effects of gravity . Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again?No, because old people don't really shrink!It is not that they are growing backwards--their legs, arms and backbones getting shorter. When they do get shorter, it's because the spine has shortened a little. Or, more often, become more bent and curved. Why does spinning make you dizzy ? Because your brain gets confused between what you're seeing and what you're feeling. The brain senses that you're spinning using special gravity and motion sensing organs in your inner ear, which work together with your eyes to keep your vision and balance stable. But when you suddenly stop spinning , the system goes out of control, and your brain thinks you're moving while you're not! Where do feelings and emotions come from? Mostly from an ancient part of the brain called the limbic system. All mammals have this brain area--from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other newer bits of the brain, we feel more complex emotions than any other animal on the planet.
Answer: Dark reddish purple.

Answer: What is the colour of blood in a vein near the surface of the skin?

Question: Article: During the week days, they are luckily busy office people; but on weekends, they are just a brood of stay-home animals. A recent survey shows that office workers in China prefer quiet and easy ways to spend their weekends. In the survey, conducted by job seeking and offering website Zhaopin.com, 32.8 percent of the 6,000 respondents choose to stay home at weekends and have a good rest, the Beijing Morning Post reported. Twenty percent use their days-off to do housework. And only 19.3 percent are willing to have fun during the break time from work. Their first choice of fun is shopping. Other choices, though practiced by few, include meeting friends, accompanying the children, trips to the suburbs, and lessons for more skills. When they. go shopping, 54.5 percent of the white-collars actually shop in supermarkets, while 27.9. percent attend other stores, especially when discounts are offered. These activities don't seem to cost much, as 60 percent spend average less than 200 yuan (US$26) during weekends, and 30 percent no more than 500 yuan. When asked whom they would spend the weekends with, about 40 percent mention their partners, and 30 percent prefer a weekend all by themselves. Less than 20 percent hang out with friends. Only 5.8 percent would kill the time with their colleagues. This is because we tend to avoid too many personal contacts with our co-workers when we don't have to work with them, according to some experts.
Answer: 1,674.
