Article: Areas of Tokyo which had usually been packed with office workers like sushi restaurants and noodle shops were unusually quiet.Many schools were closed.Companies allowed workers to stay home.Long queues formed at airports. As Japanese authorities struggled to avoid disaster at an earthquake - battered nuclear plant 240 km to the north, parts of Tokyo resembled a ghost town.Many people stocked up on food and stayed indoors or simply left.transforming one of the world' s biggest and most populated cities into a shell of its usual self. "Look, it' s like Sunday --no cars in town," said Kazushi Arisawa, a 62 - year - old taxi driver, as he waited for more than an hour outside an office tower where he usually finds customers within minutes." I can' t make money today." Radiation in Tokyo has been _ , briefly touching three times the normal rate on Tuesday, smaller than a dental X -ray.On Wednesday, winds over the Fukushima nuclear-power plant blew out to sea, keeping levels close to normal.But that does little to relieve public anxiety about a 40-year-old nuclear plant with three reactors in partial meltdown and a fourth with spent atomic fuel exposed to the atmosphere after last Friday' s earthquake and tsunami. " Radiation moves faster than we do," said Steven Swanson, a 43-year-old American who moved to Tokyo in December with his Japanese wife to help with her family business.He is staying indoor but is tempted to leave."It's scary.It's a triple threat with the earthquake, tsunami and the nuclear radiation leaks.It makes you wonder what' s next." Question: Which of the following is true of Steven Swanson? - He moved to Japan with his wife last year. - He is now on way back to the United States. - He wanted to stay on to see what' s next. - He is quite confident about the future.
He moved to Japan with his wife last year.

Read the following article and select the best answer. Article: Is pricing a plane ticket based on the passenger's weight fair? If you're taking an international flight on Samoa Air today, your fare will be based on your weight, along with that of your luggage. The cost is 93 cents to $1.06 for each kilogram. The average American woman weighs 75.5 kilograms, far from the ideal weight for her average height. Her ticket on Samoa Air, at the $1 a kilogram rate, would cost $75.50. But let's be honest here. Since the average American woman is overweight, the ticket will cost her more. Samoa Air Chief Executive Chris Langton said, "Planes are run by weight and not by seat. The plane can only carry a certain amount of weight and that weight needs to be paid."He believes other airlines should adopt the policy. It' s not a new idea. I remember a newspaper columnist years ago who put forth the idea that the heavier among us should pay more for their seats on planes, trains and buses. Who hasn' t been squeezed into a middle seat between two plus-sized folks on a flight? It' s happened to me; one time my married seatmates had purposefully chosen their seats to have more space until a sold-out flight put me between them. Not one of my better flying experiences. What if such a policy is adopted by some airlines in the United States? Could such pricing provide a much-needed motivation for Americans to reduce body weight? I hope so. But, as we know, more than one-third of us are obese and another third are overweight. The high probability is that the heavy customers will not suddenly lose weight or stop flying, but will instead choose a different airline, simply moving the supposed problem elsewhere. There's no doubt that the heavier will suffer more discrimination . Discrimination against the overweight in the United States has increased by 66 percent over the last decade --"and is comparable to rates of racial discrimination, especially among women,"wrote Yale University researcher Rebecca M. Puhl. Your weight can affect your salary, your chances for employment, how others view you... Question: The author mentions Puhl's study to show _ . - women are less likely to suffer discrimination - racial discrimination is getting worse nowadays - the ticket policy will have little influence on the obese - the ticket policy will make body discrimination more serious
(Answer)
the ticket policy will make body discrimination more serious

Read the following article and select the best answer. Article: In face of global warming, much effort has been focused on reducing greenhouse gas emissions through a variety of strategies. But while much of the research and innovation has concentrated on finding less-polluting energy alternatives, it may be decades before clean technologies like wind and solar meet a significant portion of our energy needs. In the meantime, the amount of CO2 in the air is rapidly approaching the limits proposed by the Intergovernmental Panel on Climate Change (IPCC). "As long as we're consuming fossil fuels, we're putting out CO2," says Klaus Lackner, a geophysicist at Columbia University, "We cannot let the CO2 in the atmosphere rise indefinitely." That sense of urgency has increased interest in capturing and storing CO2, which the IPCC says could provide the more than 50% reduction in emissions needed to reduce global warming. "We see the potential for capture and storage to play an integral role in reducing emissions," says Kim Corley, Shell's senior advisor of CO2 and environmental affairs. That forward thinking strategy is gaining support. The U.S. Department of Energy recently proposed putting $1 billion into a new $2.4 billion coal-burning energy plant. The plant's carbon-capture technologies would serve as a pilot project for other new coal-burning plants. But what do you do with the gas once you've captured it? One option is to put it to new uses. Dakota Gasification of North Dakota captures CO2 at a plant that converts coal into synthetic natural gas. It then ships the gas 200 miles by pipeline to Canada, where it is pumped underground in oil recovery operations. In the Netherlands, Shell delivers CO2 to farmers who pipe it into their greenhouses, increasing their production of fruits and vegetables. However, scientists say that the scale of CO2 emissions will require vast amounts of long-term storage. Some propose storing the CO2 in coal mines or liquid storage in the ocean, Shell favors storing CO2 in deep geological structures such as saline formations and exhausted...
