[EX Q]: Question: What other advertisements did Microsoft release the year it launched The Life? Passage:The Life, also known as We Are ODST is a television and cinema advertisement launched in 2009 by Microsoft to promote the first person shooter  in the United States. The 150-second piece follows a young soldier through enlistment, training, and battle as an Orbital Drop Shock Trooper (ODST), analogous to a paratrooper that drops from space to a battlefield. The Life was created by advertising agency T.A.G., an offshoot of McCann Erickson. Production of the commercial itself was handled by production company Morton/Jankel/Zander (MJZ). It was directed by Rupert Sanders, and post-production was conducted by Asylum. It was filmed in Hungary, just outside Budapest in a coal mine and abandoned factories to give the sequence an "Eastern Bloc" aesthetic. The commercial and its associated campaign proved hugely successful; on the week of its launch, Halo 3: ODST became the top-selling game for the Xbox 360 worldwide, and over 2.5 million copies were sold within the first few weeks of release. The Life went on to win a number of honours from the advertising and entertainment industries, including two Clio Awards, a London International Advertising Award and several honours from the Cannes Lions International Advertising Festival, the most prestigious awards ceremony in the advertising industry.

[EX Q]: 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.
