Article: Hong Kong is one of the most densely populated cities in the world, but with night skies around 1,000 times brighter than globally accepted levels, it gains a bad reputation for its light pollution. A study by Hong Kong University found that brightness levels in the southern Chinese city's popular shopping district of Tsim Sha Tsui were 1,200 times greater than the international dark sky standard. The crowded city of 7 million residents , full or residential high-rises, towering office blocks and neon advertisements, has no laws to control outdoor lightning. The result is that light pollution is thought to be much worse than in other large cities, including London, Sydney, Tokyo and Shanghai. "In Hong Kong , you can't go anywhere outdoor in the evening without your eyes being blinded by this really disturbing outdoor lightning," the light pollution survey's head Jason Pum told AFP. "The fact that we have all this light in the sky means energy is wasted," he said, adding that too much artificial lightning also affects nightly wildlife. Research has suggested that light pollution can cause a number of harmful health effects in humans, including sleeplessness and headaches and can also interrupt body clocks and hormones . The university survey, the result of five million measurements taken from points across the city, was released just days before the start of the annual Earth Hour event, organized by the World Wildlife Fund. People around the world will be encouraged to turn off the lights for an hour on Saturday night to raise awareness of climate change. Last year, a number of Hong Kong's major buildings along Victoria Harbour went dark to mark Earth Hour. "Anyway, we should do our best to reduce the amount of lightning and adjust it for the benefit of the environment." Question: .which of the following statements about too much lightning is NOT true? - Too much lightning means a waste of energy. - It can make the sky and the city more beautiful. - It may have a bad effect on nightly wildlife. - It can lead to some health problems.
It can make the sky and the city more beautiful.

Read the following article and select the best answer. Article: Very old people do raise moral problems for almost everyone who comes in contact with them. Their values--this can't be repeated too often--are not necessarily our values. Physical comfort, cleanness and order are not necessarily the most important things. The social services from time to time find themselves faced with a flat with decaying food covered by small worms , and an old person lying alone in bed, taking no notice of the worms. But is it interfering with personal freedom to insist that they go to live with some of their relatives so that they might be taken better care of? Some social workers, the ones who clear up the worms, think we are in danger of carrying this concept of personal freedom to the point where serious risks are being taken with the health and safety of the old. Indeed, the old can be easily hurt or harmed. The body is like a car, it needs more mechanical maintenance as it gets older. You can carry this comparison right through to the provision of spare parts. But never forget that such operations are painful experiences, however good the results. And at what point should you stop treating the old body? Is it morally right to try to push off death by pursuing the development of drugs to excite the forgetful old mind and to activate the old body, knowing that it is designed to die? You cannot ask doctors or scientists to decide, because so long as they can see the technical opportunities, they will feel bound to give them a try, on the principle that while there's life, there's hope. When you talk to the old people, however, you are forced to the conclusion that whether age is happy or unpleasant depends less on money or on health than it does on your ability to have fun. Question: In the author's opinion, _ . - the human body can't be compared to a car - the older a person, the more care he needs - too much emphasis has been put on old people's values - it is easy to provide spare parts for old people
the older a person, the more care he needs

Read the following article and select the best answer. Article: WASHINGTON--More than one in 10 of the nation's airline pilots are cleared to carry a handgun while flying, and the number will continue to grow, according to a Transportation Security Administration projection. The Federal Air Marshal Service, a TSA agency that runs the armed-pilots program, reports that 85,000 to 90,000 pilots and crewmembers flying domestic passengers and cargo planes are eligible to carry a gun. That puts the number of armed pilots at about 9,500. The TSA projects the program to grow to 16.5% of eligible pilots by the year 2011. Aviation experts were surprised and alarmed that so many pilots are toting guns in the sky. "That's a big number compared to what I thought it would be," said aviation-security consultant Rich Roth, who said he had predicted there would be fewer than 1,000 armed pilots. The 5-year-old program trains pilots for one week and arms them with 40-caliber semiautomatic pistols. "That's a scary number," said Joseph Gutheinz, a former Transportation Department special agent and aviation attorney in Houston. "By allowing so many pilots the opportunity to fly armed, we're giving terrorists opportunity to identify somebody who has a gun and overpower him." Capt. Bob Hesselbein, head of security for the Air Line Pilots Association, said the number of armed pilots is "a tremendous deterrent " to hijackings. "The challenge of an organized terrorist team is to take control of the cabin, then the flight deck." Armed pilots have come under scrutiny since March 22 when the gun of a US Airways pilot fired in the cockpit of Flight 1536 as it approached Charlotte from Denver. No one was hurt, and the plane landed safely after the bullet pierced the fuselage. Question: The best title for this passage is " _ ". - More than 10% of pilots allowed to fly armed - Less than 10% of pilots allowed to fly armed - More than 16.5% of pilots allowed to fly armed - No chances for terrorists to hurt pilots
More than 10% of pilots allowed to fly armed
