Ques: Electronic waste, or e-waste, refers to electronic products that are no longer usable. This can include TVs, cell phones and computers and other office electronics, electronic toys and videos machines. Today, the average turnover rate for a computer in the United States is every two years, according to the environmental group, Greenpeace. The group's Dai Yun says e-waste is a global problem. "The electronic industry is one of the fastest growing industries in the world. The high speed of growth in this industry means more and more electronic products are being wasted and thrown away. If no one decides to retrieve the old products and process them properly, the electronic waste will sweep over the earth like the huge wave behind me and pollute the Earth seriously." Greenpeace works out that 20 to 50 million tons of e-waste are produced globally each year. The components in many electronic products contain harmful chemicals that pollute ground water and the environment. At present , the U.S. has no federal law for the disposal   of e-waste although a few states have e-waste recycling programs in place, but there is no law. The U.S. exports much of its e-waste to third world countries, such as India and China, where workers took apart computers for valuable parts, hoping to sell them for money. But harmful wastes expert, Dr. Bakul Rao, says that's a dangerous practice. "From now on, the recyclers are not very educated. All they know is they can retrieve copper or gold out of it. So, the easiest way to do that is leach   it out in an acid or burn it off to retrieve it. So, that's where they don't know how to deal with it, neither do they have any health systems in place. So, their exposure is more." Which of the following is most likely not to be a form of e-waste? A) A mobile phone B) A radio C) An e-bike D) A table
Ans: D

Ques: Do's and Don'ts in Whale Watching The Department of  Fisheries and Oceans has developed guidelines for whale watching in Johnstone Strait,where killer whales are found on a daily basis each summer. It is strongly recommended that vessel operators follow these guidelines for all kinds of whales. * Approach whales from the side, not from the front or the back. * Approach no closer than 100 metres, then stop the boat but keep the engine on. * Keep noise levels down-no horns, whistles or racing of engines. * Start your boat only after the whales are more than 100 metres from your vessel. * Leave the area slowly, gradually moving faster when you are more than 300 metres from the whales. * Approach and leave slowly, avoiding sudden changes in speed or direction. * Avoid disturbing groups of resting whales. * Keep at low speeds and remain in the same direction if travelling side by side with whales. * When whales are travelling close to shore, avoid crowding them near the shore or coming between the whales and the shore. * Limit the time spent with any group of whales to less than 30 minutes at a time when within 100 to 200 metres of whales. * If there is more than one vessel at the same observation spot, be sure to avoid any boat position that would result in surrounding the whales. * Work together by communicating with other vessels, and make sure that all operators are aware of the whale watching guidelines. When leaving the observation areas, the vessel should   _  . A) move close to the beach B) increase speed gradually C) keep its engine running slowly D) remain at the back of the whales
Ans: B

Ques: One day,a poor boy who was trying to pay his way through school by sending news-papers door to door,was so hungry that he decided to beg for a meal at the next house. However, he lost his courage when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly,and then asked, "how much should I pay you?" "You don't owe me anything," she replied. "Then I thank you from the bottom of my heart." With these words,the boy left that house. Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly,now famous,was called in. When he heard the name of the town she came from, a strange light filled his eyes.Dressed in his doctor's clothes,Dr.Kelly went into her room and recognized her at once.

Ques: No woman can be too rich or too thin. This saying often attributed to(...) the late Duchess   of Windsor represents much of the strange spirit of our times. Being thin is assumed as such a virtue. The problem with such a view is that some people actually attempt to live by it. I myself have fantasies of slipping into narrow designer clothes. Consequently, I have been on a diet for the better --or worse-- part of my life. Being rich wouldn't be bad either, but that won't happen unless an unknown   dies suddenly in some distant land, leaving me millions of dollars. Where did we go off the track? When did eating butter become a sin , and a little bit of extra flesh unappealing, if not unpleasant? All religions have certain days when people stop from eating and overeating is one of Christianity's seven deadly sins. However, until quite recently, most people had a problem getting enough to eat. In some religious groups, wealth was a symbol of probable high morals, and fatness a sign of wealth and well-being. Today the opposite is true. We have shifted to thinness as our new mark of virtue. The result is that being fat -- or even only somewhat overweight -- is bad because it implies a lack of moral strength. Our obsession with thinness is also fueled by health concerns. It is true that in this country we have more overweight people than ever before, and that in many cases, being overweight correlates with an increased risk of heart and blood vessel disease. These diseases, however, may have as much to do with our way of life and our high-fat diets as with excess weight. And the associated risk of cancer in the digestive system may be more of a dietary problem -- too much fat and a lack of fiber -- than a weight problem. The real concern, then, is not that we weigh too much, but that we neither exercise enough nor eat well. Exercise is necessary for strong bones and both heart and lung health. A balanced diet without a lot of fat can also help the body avoid many diseases. We should surely stop paying so much... Swept by the current trend, the author  _  . A) could still prevent herself from going off the track B) had to go on a diet for the greater part of her life C) had to seek help from rich distant  s D) had to wear highly fashionable clothes
