Article: In the atmosphere, carbon dioxide acts rather like a one-way mirror or the glass in the roof of a greenhouse which allows the sun's rays to enter but prevents the heat from escaping According to a weather expert's prediction , the atmosphere will be 3degC warmer in the year 2050 than it is today, if man continues to burn fuels at the present rate.If this warming up took place.the ice caps in the poles would begin to inch,thus raising sea level several meters and severely flooding coastal cities.Also.the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere ,possibly resulting in an alteration of the earth's chief food growing zones. In the past,concern about a man-made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet.But the weather experts are now paying more attention to West Antarctic.which may be affected by only a few degrees of warming,in other words,by a warming on the scale that will possibly take place in the next fifty years from the burning of fuels. Satellite pictures show that large areas of Antarctic ice are already disappearing.The evidence available suggests that a warming has taken place.This fits the theory that carbon dioxide warms the earth. However, most of the fuel is burnt in the northern hemisphere,where temperatures seem to be falling.Scientists conclude,therefore ,that up to now natural influences on the weather have gone beyond those caused by man.The question is:Which natural cause has most effect on the weather? One possibility is the variable behavior of the sun.Astronomers at one research station have studied the hot spots and 'cold' spots (that is, the ly less hot spots)on the sun.As the sun rotates ,every 27.5 days,it presents hotter or colder faces to the earth,and different aspects to different parts of the earth.This seems to have a considerable effect on the distribution of the earth atmospheric pressure,and consequently on wind... Question: Although the fuel consumption is greater in the northern hemisphere, temperatures there seem to be falling.This is_. Yes or no, is the answer "partly due to changes in the output of solar energy"?
No

Article: President Obama: I want to welcome Vice President Xi to the Oval Office and welcome him to the United States. This is obviously a great opportunity for us to build on the U. S.-China relationship, but also an opportunity to return the extraordinary hospitality that Vice President Xi showed Vice President Biden during his recent visit to China. As I indicated during my recent visit to APEC and the East Asia Summit, the United States is a Pacific nation. And we are very interested and very focused on continuing to strengthen our relationships, to enhance our trade and our commerce, and make sure that we are a strong and effective partner with the Asia Pacific region. And obviously, in order to do that, it is absolutely vital that we have a strong relationship with China. So, Mr. Vice President, I hope you have a wonderful visit while you're here. I'm sure the American people welcome you. I'm glad that you're going to get an opportunity to get out of Washington. I know you'll be visiting Lowa, which you visited many years ago when you were governor. And I understand you're also going to Los Angeles and maybe even taking in a Lakers basketball game. So I hope you enjoy that very much. I want to extend my deepest welcome to you, and look forward to a future of improved dialogue and increased cooperation in the years to come.

Q: Article: The Magic Kingdom was the first theme park at Walt Disney World, opening in 1971. All Disney World theme parks are open 365 days a year, although opening and closing times for each park are different. If you are traveling without kids, try to visit on a school day to avoid the largest crowds. If you need to visit during a school vacation, try to avoid the week between Christmas and New Year's and the Fourth of July. If you are not staying at a Disney World hotel, avoid visiting the Magic Kingdom on its Extra Magic Hours days, as Disney's hotel guests get into the park early on those days, _ wait times for visitors who arrive at the Magic Kingdom's normal opening time. Buy your Walt Disney World tickets online at Disney World's website. For advice on picking the right ticket, see our guide to Disney World tickets. You will also need to call in advance to make lunch and/or dinner reservations . Disney accepts reservations, through 1-407-WDW-DINE, up to 180 days in advance. Times do go quickly, so you should call six months before your trip to get a lunch reservation in the castle. We recommend you should have your lunch at Cinderella's Royal Table for your tour. Plan to arrive at the Magic Kingdom's front gate before the park opens in the morning. You can check the Magic Kingdom's opening time through Disney World's website. Keep in mind that to reach the Magic Kingdom, you must park at Disney World's Transportation and Ticket Center parking lot, ride at tram to the TTC, then take a boat across the Seven Seas Lagoon to the Magic Kingdom. It will take you extra time to get there. Give yourself an extra hour in the summer and half-hour during the school year. Question: We may infer from the passage that _ . Yes or no, is the answer "there are many students in Disney World theme parks during important festivals"?
A: No

*Question*
Article: President Coolidge's statement, "The business of America is business," still points to a very important truth today -- that business organizations have more prestige in American society than any other kind of organization, including the government. Why do business institutions still possess this great prestige? One reason is that Americans view business as being more firmly based on the idea of competition than other organizations in society. Since competition is seen as the main source of progress and development by most Americans, competitive business organizations are respected. Competition is not only good in itself; it is the means by which other basic American values, such as individual freedom, equality of opportunity, and hard work are protected. Competition protects the individual freedom by making sure that there is no monopoly of power. Compared with one and all-powerful government, many businesses compete against each other for benefit. If one business tries to take unfair advantage of its customers, it will lose to the competing business which treats its customers more fairly. Since there are many businesses competing for the customers' dollars, they cannot afford to treat them unfairly and the customers would lose nothing.A contrast is often made between business, which is competitive, and government, which is a monopoly. Because business is competitive, many Americans believe that it gives more support for freedom than government, even though government leaders are elected by the people while business leaders are not. Many Americans believe that competition is as important, or even more important, as democracy in protecting freedom. Competition in business is also believed to strengthen the idea of equal opportunities. Competition is seen as an open and fair race where success goes to any person regardless of his or her social class background. Competitive success is commonly seen as the American choice of the higher social position which is not based on one's family background. Business is...
