[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: The hole in the earth's protective ozone layer won't repair itself until about two decades later than had been expected, scientists announced. The ozone layer blocks more than 90 percent of the sun's ultraviolet radiation , helping to make life on Earth possible. For many dacades, ozone was depleted by chlorine and bromine gas in the air. A hole in the ozone layer formed over the Southern Hemisphere. Computer models had forecast that the hole would fill back in by 2050. An improved computer model forecasts the recovery won't occur until 2068. The model, fed with fresh data from statellites and airplanes, was supported by the fact that it accurately reproduced ozone levels in the Antarctic stratosphere over the past 27 years. The ozone hole is actually more of a broad region with less ozone than ought to occur naturally. It is not limited to Antarctica, as is often believed. Over areas that are farther from the poles like Africa or the US, the levels of ozone are only three to six percent below natural levels. Over Antarctica, ozone levels are 70 percent lower in the spring. This new method allows us to more accurately estimate ozone-depleting gases over Antarctica, and how _ will decrease over time, reducing the ozone hole area. Paul Newman, a scientist,said that the ozone hole has not started to become smaller as quickly as expected. They figure it will not become much smaller until 2018, after which time the recovery should proceed more quickly. And the hole will not be filled in again until 2065. Options: A it was once proved by facts B it has been studied for 27 years C it was created by many scientists D it is related to satellites and airplanes Answer: A it was once proved by facts Question:

[A]: The improved computer model is believable because _

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Dana Cummings was in his thirties before he first went surfing. But, even more interesting is that Dana Cummings chose to learn the sport after losing a leg in a car accident. Now, nine years later, he helps other disabled people learn how to ride the waves in AmpSurf. On the coast of Maine, he is working with 27-year-old Matthew Fish, who is partly blind. Cummings takes hold of Fish and leads him into the ocean. The surfboard floats next to them. Fish lies on the surfboard. He tries to stand up on it. After a few attempts he is up and riding all the way back to land. "That was exciting," Fish says. A car accident in 2002 took Dana Cummings' leg. He says the crash changed him more than just physically. "Losing my leg made me realize how precious life is and get off the couch and start living. I do more things now than I ever did before. Next week I am going to compete in a contest in Hawaii," Dana says. One year later Dana Cummings formed AmpSurf. AmpSurf is a group that volunteers to hold surfing classes and events for people with all kinds of disabilities. Recently, AmpSurf took its training programs to the East Coast. Eleven students attended the class in Maine. They came from all over the northeastern United States. Dana Cummings thinks AmpSurf can change the way a disabled person thinks. "Most people with disabilities consider himself or herself unlucky and useless, but we want them to see what they can do. Who cares you lose your leg or you are blind, whatever? Have fun. Just enjoy life. Take the most advantage of _ you can," Dana says.

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Vacation is a time for refreshment. In work, we are often called to think. Sometimes, it's good to give our brains a rest. Without a break, we may not be able to perform up to our potential. This can be a problem, not only for the employee, but for the employer as well. "The main benefit of vacation is for the worker to come back energized," says Weaver. "If they haven't had a break, then they're not coming back with new energy. They haven't had a chance to step back and get perspective , and come back with renewed enthusiasm." Long working hours without a break, insecurity about one's job, and other work-related worries can lead to burnout and stress. Humans can usually adapt to pressure, but not for a limitless amount of time. "It is a problem of relating good workers and having them loyal to the firm while they're _ ," says David Maume, PhD, professor of sociology at the University of Cincinnati. He says burnout can also affect employees' productivity, creativity, and effectiveness. In addition, high levels of stress are likely to be precursors to depression, which can hit both the employer and employee's pocketbook. Even people who manage to remain productive at work can have problems. If they're always at work, then they're not with their family and friends. If they're working while on vacation, for the time that they're on the job, they're not really present. An unbalanced emphasis on work can strain family and social life. When you come up for air, you may see that you're alone, or that your relationships have gone on without you. Options: A dynamic B productive C skillful D absent-minded Answer: D absent-minded Question:
