Example 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.

Example Input: Question: Who was older the year Dane appeared on Jackie Gleason's show, Otis Spann or Willie Dixon? Passage:By 1959, Louis Armstrong had asked Time magazine readers: "Did you get that chick? She's a gasser!" and invited her to appear with him on national television. She appeared with Armstrong on the Timex All-Star Jazz Show hosted by Jackie Gleason on January 7, 1959. She toured the East Coast with Jack Teagarden, appeared in Chicago with Art Hodes, Roosevelt Sykes, Little Brother Montgomery, Memphis Slim, Otis Spann, Willie Dixon and others, played New York with Wilbur De Paris and his band, and appeared on The Tonight Show Starring Johnny Carson as a solo guest artist. Other national TV work included The Steve Allen Show, Bobby Troup's Stars of Jazz, and Alfred Hitchcock Presents. In 1961, the singer opened her own club, Sugar Hill: Home of the Blues, on San Francisco's Broadway in the North Beach district, with the idea of creating a venue for the blues in a tourist district where a wider audience could hear it. There Dane performed regularly with her two most constant musical companions: Kenny "Good News" Whitson on piano and cornet and Wellman Braud, former Ellington bassist.

Example Input: Question: How long is the road that intersects with PA 528 in Jackson Township? Passage:PA 528 begins at an intersection with US 19 in Jackson Township, heading northeast on two-lane undivided Lindsay Road. A short distance past US 19, the route comes to a partial interchange with Interstate 79 (I-79), with access to the southbound direction, and from the northbound direction of I-79. After this interchange, the road passes east of a park and ride lot and heads northeast through wooded areas with some rural homes. PA 528 comes to an intersection with PA 68, at which point the route turns southeast to form a concurrency with PA 68 on Evans City Road. The road passes through woods before heading into the borough of Evans City, where it becomes West Main Street and runs past homes and businesses. The two routes curve to the east and cross the P&W Subdivision railroad line, which is owned by CSX and operated by the Buffalo and Pittsburgh Railroad, and the Breakneck Creek into the commercial downtown of Evans City, becoming East Main Street. PA 528 splits from PA 68 by turning north onto Franklin Street and passing residences before heading into woods. The route leaves Evans City for Jackson Township again and becomes Prospect Road. The road curves northeast and enters Forward Township, coming into a mix of farmland and woodland with a few rural homes. PA 528 continues north and crosses over a Buffalo and Pittsburgh Railroad line before reaching the community of Wahlville.
