Example Input: Question: What other commercials did Rupert Sanders direct the year he directed 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.

Example Input: Question: Which of the founders of the Achae was born first? Passage:Achaea was founded in 1205 by William of Champlitte and Geoffrey I of Villehardouin, who undertook to conquer the Peloponnese on behalf of Boniface of Montferrat, King of Thessalonica. With a force of no more than 100 knights and 500 foot soldiers, they took Achaea and Elis, and after defeating the local Greeks in the Battle of the Olive Grove of Koundouros, became masters of the Morea. The victory was decisive, and after the battle all resistance from the locals was limited to a few forts, that continued to hold out. The fort of Araklovon in Elis, was defended by Doxapatres Boutsaras and withstood the attacks until 1213, when the garrison finally surrendered. The fort of Monemvasia, and the castles of Argos, Nauplia and Corinth under Leo Sgouros held out until his suicide in 1208. By 1212, these too had been conquered, and organized as the lordship of Argos and Nauplia, and only Monemvasia continued to hold out until 1248. William of Champlitte ruled Achaea until he departed for France to assume an inheritance, but died on the way there in 1209. He was succeeded by Geoffrey I of Villehardouin, who ruled until his own death in 1219.
