Input: Consider Input: Article: If you want to see climate change, head north and keep going until you run out of globe. That is easier said than done. The Arctic is home to few people and covered in ice much of the year. But those who make their way to the icy seas of the Arctic Ocean will see a part of the planet that is warming and changing faster than anywhere else. In September, scientists announced at the National Snow and Ice Data Center that Arctic summer sea ice had fallen to its second lowest level since 1979, and probably long before that. The Arctic has lost an area of ice greater than the area of all U.S. states east of the Mississippi River. And what ice remains appears to be getting thinner and weaker. Nick Toberg and Till Wagner are polar ice scientists who are doing sea ice fieldwork. "There is plenty of data to suggest that the ice is becoming thinner as well as smaller in area," they say. The changes happening in the Arctic are a warning for the entire world . As polar expert Walt Meier puts it, " _ Some scientists worry that Arctic sea ice may be going from a downward spiral to a "death spiral", one from which there is no escape. As more ice melts , more dark open water appears. The darkness absorbs more heat, which speeds up the pace of melting. Until recently, many scientists thought it might take until the end of the century for the North Pole to become completely ice free during the summer. Now some believe it could happen by 2030 or even earlier. "The melting is happening faster in the real world than it has in the models," says Nick Toberg.
Question: Nick Toberg may agree that _ .
Options: (A) the ice in the North Pole will stop melting (B) the ice in the North Pole is melting faster than expected (C) the ice in the North Pole will melt before 2030 or even earlier (D) the ice in the North Pole will not disappear until the end of the century

Output: B

Input: Consider Input: Article: For new countries joining the European Union, and older ones getting used to their dark red passports, becoming "Europeans" is a bit like marrying into a large, eccentric family. Europeans have a lot in common but it is their differences, not their similarities, that attract the attention of sociologists and market researchers, and are more interesting. * 35% of Germans live alone, but only 9% of Spaniards. Perhaps this explains why Spaniards lead Europe in the habit of going out for a drink. * The British attend more adult evening classes than anyone else in Europe, and the Belgians least. So it can't just be the dark evenings. There are no figures on how many Britons go for a drink afterwards. If there were, they might be up at the top with Spain! * The British think black cats are lucky. Every other European country regards them unlucky. * The Dutch and Germans are the greatest caravaners , but the Germans like bigger beds in their caravans. * The French are the most athletic Europeans. Next come the Dutch. But the Belgians, just over the border, play fewest sports. * The Germans spend twice as much on heating as the Spaniards. Well, of course they do, it's colder. * Dutch husbands do the household shopping a lot more often than Italians or Spaniards. * The French are the champion public transport commuters of Europe. If you hate commuting, go and live in the Netherlands, where journeys to work are shorter than anywhere else. * The amount of direct eye-contact between strangers is three times greater among Spaniards than it is among the British or Swedes. Sharing a lift is torture for both the British and the Swedish. * No European countries really agree with any other about how to make good coffee. All of them are different. There are exceptions to all these rules. Deal with them in the spirit of my 8-year-old daughter. "If you don't understand each other's language, you just laugh a lot, and eat, and point at things."

Options: (A) sociologists are most interested in the idea of the European Union (B) all the European countries are not willing to join the European Union (C) Europeans have a lot more differences than similarities (D) trade opportunities exist in the cultural differences in the European Union

Output: A
