Example Input: Question: What year was the character that Sweed patterned his character after created? Passage:Other programming on WKBF included a late-night weekend horror movie showcase hosted by Ron Sweed, whose on-air character was named The Ghoul. The Ghoul character was essentially a beatnik vampire, outfitted in a fright wig, goatee, lab coat, and a pair of sunglasses with one lens missing. It was patterned after the Ghoulardi character that was created by Ernie Anderson (with his permission), who was later to become the voice of the ABC network in the 1970s. While Anderson had no interest in doing so, he granted Sweed permission to don the costume. As WJW owned the rights to the name "Ghoulardi", the younger performer adopted the name "The Ghoul." Although WKBF has long since passed into broadcasting history, Sweed continued to make personal appearances on a fee-for-service basis in this guise until very late in life. WKBF also featured sports programming such as game telecasts from the World Football League and Cincinnati Royals NBA basketball, and harness racing.

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.
