Indicate your choice as `a` for Yes or `b` for No.

Example Input: Question: Who was the leader of the Porte in 1912? Passage:The modern Albanian-Serbian conflict has its roots in the expulsion of the Albanians in 1877-1878 from areas that became incorporated into the Principality of Serbia. Prior to the outbreak of the First Balkan War, the Albanian nation was fighting for a national state. At the end of 1912, the Porte recognised the autonomy of Albanian vilayet. These events for Albanian autonomy and Ottoman weakness were viewed at the time as directly threatening the Christian population of the region with extermination. The Balkan League (comprising Serbia, Montenegro, Greece and Bulgaria) jointly attacked the Ottoman Empire and during the next few months partitioned all Ottoman territory inhabited by Albanians. The Kingdom of Serbia and the Kingdom of Greece occupied most of the land of what is today Albania and other lands inhabited by Albanians on the Adriatic coast. Montenegro occupied a part of today's northern Albania around Shkodër. The Serbian army in the region viewed its role as protecting local Orthodox Christian communities and avenging the medieval battle of Kosovo, though it forced Catholic Albanians to convert to Orthodox Christianity.

Example Input: Question: Which of the cities where the cup matches have been held has a larger population? Passage:In 2002, the International Ice Hockey Federation (IIHF) announced that it would acknowledge the site of Victoria Rink with "a commemorative plaque or other historical site marker to remind the passers-by of the existence of the Victoria Skating Rink, the birthplace of organized hockey." The commemoration has been marked in two ways. On May 22, 2008, a commemorative plaque was dedicated at the nearby Centre Bell, along with a plaque honouring James Creighton. Further, the IIHF created the Victoria Cup, a trophy named for the arena, for which—along with 1 million Swiss francs—one National Hockey League team and the champion of the European Champions Hockey League play-off annually. The first Cup match was held in Berne, Switzerland on October 1, 2008 between the New York Rangers and the Metallurg Magnitogorsk. The next, and last, edition of the Victoria Cup was held in Zurich on September 29, 2009, between the ZSC Lions and the Chicago Blackhawks.

Example Input: Question: What year did the cable network Gasparino worked for first go on air? Passage:Gasparino was previously a senior writer for Newsweek, where he covered politics, Wall Street, and corporate America, and among other stories broke the news of the controversial pay package of former New York Stock Exchange chairman Richard Grasso, former New York City Police Commissioner Bernard Kerik's controversial (and eventually withdrawn) nomination to run the US Department of Homeland Security, and the dispute surrounding former New York Attorney General (and eventual Governor) Eliot Spitzer's crackdown on corporate crime.
