Example Input: Article: Signs in Chinese will be set up in public areas such as airports, to benefit Chinese travelers, the Italian Government announced in late February. _ . Despite the different languages, travel across Europe has never been so simple. Just five years ago, if you wanted to visit Germany in the north and Spain in the south in one trip, you had to wait for weeks to apply for different visas from the two countries. You also needed a calculator because both countries had different money. Today, with a Schengen Visa issued by any member country, you can travel across 15 European countries without stopping. Since 2002, within most of the EU, there is now just one type of money called the Euro. The Euro was designed to be the only money in the EU, and already makes it easier to shop around. If you drive, your driving license and car insurance policy are valid in the other European countries. And you can use your mobile phone everywhere. All the countries in the continent are melting into a united Europe under the EU. For Europeans and visitors, the result is that it is more convenient to travel back and forth between the different countries.

Example Output: D

Example Input: Article: Christmas in Australia is often very hot. Whereas the northern hemisphere is in the middle of winter, Australians are baking in summer heat. It is not unusual to have Christmas Day well into the mid 30 degrees Celsius, or near 100 degrees Fahrenheit. A traditional meal includes a turkey dinner, with ham, and pork. A flaming Christmas plum pudding is added for dessert. In the Australian gold rushes, Christmas puddings often contained a gold nugget. Today a small favor is baked inside. Whoever finds this knows s/he will enjoy good luck. Another treat is Mince Pies. Some Australians and particularly tourists often have their Christmas dinner at midday on a local beach, Bondi Beach in Sydney's Eastern Suburbs attracts thousands of people on Christmas Day. Other families enjoy their day by having a picnic. If they are at home, the day is punctuated by swimming in a pool, playing Cricket out the backyard, and other outdoor activities. The warm weather allows Australians to enjoy a tradition which started in 1937. Carols by Candlelight is held every year on Christmas Eve, where tens of thousands of people gather in the city of Melbourne to sing their favorite Christmas songs. The evening is lit by as many candles singing under a clean cut night sky. The sky with its Southern Cross stars is like a mirror. Sydney and the other capital cities also enjoy Carols in the weeks leading up to Christmas. Australians surround themselves with Christmas Bush, a native plant which has little red flowered leaves.

Example Input: Article: The Haitian tsunami gave scientists a chance to find out how well vital and potentially life-saving warning systems were working. Noaa's Pacific Marine Environmental Laboratory has developed a warning system that picks up signals of tsunamis directly from the sea-floor. It is called Dart-the Deep-ocean Assessment and Reporting of Tsunamis. If seismometers detect an earthquake, the Dart buoys will determine what is happening to sea levels, and whether a big wave might be on the way. This information is then sent via satellite to a central location which can organize an alarm. Within 50 minutes of the Haiti earthquake, this system was able to issue an alarm to other countries in the Caribbean to say that a small tsunami had been caused to start, and that was unlikely to affect them. Dr Bernard said, "The first 30 minutes following the earthquake, we have to rely on education." The critical aspects of this are: do you feel the earthquake; do you see the ocean draw down; and do you hear that loud roar? If so, you should run for higher ground. "But after the first few minutes, it's crucial that we have the technology--the measurements to avoid unnecessary evacuation and tell people when it is safe to return." Right now, there are 50 of these Dart buoys all over the globe--four of which are in the Caribbean. Dr Bernard says that, with 75 to 100 buoys worldwide, this system could provide global tsunami warnings within one hour. "That's for everywhere we know that tsunamis have happened. If we wanted to go to half an hour detection, we could probably double or multiply by four times that number," he said. "In some countries, including Haiti, there may not be enough resources to support a specific tsunami warning centre for something that happens so infrequently." He said that this system was relatively inexpensive to fix and operate. "To get it down to an hour for everywhere affected would cost $50m initial investment and then 10% of that to maintain it," he said. "That's not a terribly expensive system considering the potential savings of lives."
