Input: Consider Input: 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.

Input: Consider Input: Question: Which city had a greater population the year Gordon led his regiment to the Battle of Marks' Mills, Little Rock or Camden? Passage:In March and April 1864, Shelby's men harassed and skirmished with the Union Army force under the command of Major General Frederick Steele during his Camden Expedition, part of the Red River Campaign. Gordon led more than one charge against the Union forces during Steele's march from Little Rock to Camden, Arkansas. On April 25, 1864, Gordon led his regiment at the Battle of Marks' Mills where they captured two Union artillery pieces from the detachment of Union Lieutenant Colonel Francis M. Drake when Shelby's force attacked the Union left wing of the detachment which had been sent from Camden toward Pine Bluff, Arkansas to obtained supplies for Steele's force which was increasingly besieged by gathering Confederate forces at Camden. The Confederates outnumbered the Union force at Marks' Mills by more than 2 to 1 and overwhelmed it, taking about 1,300 prisoners and about 240 wagons. The overall commander of the Confederate cavalry force at Marks' Mills, Brigadier General James Fagan, led the Confederates, including Shelby's command, toward Pine Bluff in an effort to capture the Union supply depot. The Confederates did not make it to Pine Bluff due to flooding. They also did not return fast enough to cut off Steele's return march to Little Rock or to participate in the Battle of Jenkins' Ferry, the one big engagement during the retreat before the Union troops escaped across the swollen Saline River.

Input: Consider Input: Question: How many people have received the medal that Lance Corporal Donald Hogan was posthumously awarded for his actions on August 26th? Passage:In 2009 the Taliban began moving even more men into Nawa, possibly for additional attacks against Lashkar Gah. On May 13, they launched an attack against the Afghan National Police in the district, that overwhelmed several posts. By late spring they had established a solid foothold in the district. On July 2, 2009, Marines from the 1st Battalion, 5th Marines (1/5) occupied the district as part of Operation Strike of the Sword. They set up their headquarters in Forward Operating Base Geronimo. On August 26, Lance Corporal Donald Hogan, a Marine with 1/5, threw himself in front of an improvised explosive device (IED), saving the Marines in his squad. He was later posthumously awarded the Navy Cross for his actions. In December, 1/5 was replaced by 1st Battalion, 3rd Marines. In the late summer and early fall the Marines detained Haji Adam, one of Nawa's main drug lords, and turned his house into Combat Outpost (COP) Sullivan. In November two local officials were assassinated. On December 17, Admiral Mike Mullen, the Chairman of the Joint Chiefs of Staff, visited Patrol Base Jaker and touted the security gains by touring the Nawa district center without wearing body armor. Several weeks later Afghan President Hamid Karzai and ISAF commander General Stanley McChrystal also visited Nawa on January 2, 2010. On January 9 British journalist Rupert Hamer and two Marines were killed by an IED in the district.
