In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.

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: Where was the person who featured Kelly in his video "A Thousand Miles from Nowhere" born? Passage:MCA embarked on a big marketing campaign to tout Willis after she recorded her first album on the label, the 1990 album Well Travelled Love. MCA ensured that Willis was interviewed by several national magazines including unusual venues like Vogue and Mademoiselle. Her voice appeared in the 1991 Ridley Scott-produced movie Thelma and Louise, singing "Little Honey." Willis also had a small part in Tim Robbins’ 1992 film Bob Roberts. Willis appears as the young woman standing in a shallow stream in Dwight Yoakam's video of "A Thousand Miles from Nowhere," as well as a member of Vince Gill's "pickup band" in his Don't Let Our Love Start Slippin' Away video. She was also nominated for Top New Female Vocalist of the year at the 1993 ACM Awards along with Faith Hill and Lari White (Hill wound up winning the award). Despite of all the publicity and positive reviews from most reviewers, Well Travelled Love and Willis’s subsequent albums for MCA (Bang Bang in 1991 and Kelly Willis in 1993) sold modestly and received very little radio play. During this time, Willis felt uncomfortable with the way she was marketed by MCA. In 1994, MCA released Willis from her contract.

Example Input: Question: How many copies did "My Generation" sell the year it was released? Passage:A deliberate use of acoustic feedback was pioneered by Blues and Rock'n'Roll guitarists such as Willie Johnson, Johnny Watson and Link Wray. According to AllMusic's Richie Unterberger, the very first use of feedback on a commercial rock record is the introduction of the song "I Feel Fine" by the Beatles, recorded in 1964. Jay Hodgson agrees that it was the first chart-topper to showcase feedback distortion, created by John Lennon leaning a semi-acoustic guitar against an amplifier. The Who's 1965 hits "Anyway, Anyhow, Anywhere" and "My Generation" featured feedback manipulation by Pete Townshend, with an extended solo in the former and the shaking of his guitar in front of the amplifier to create a throbbing noise in the latter. Canned Heat's "Fried Hockey Boogie" (off of their 1968 album Boogie with Canned Heat) also featured guitar feedback produced by Henry Vestine during his solo to create a highly amplified distorted boogie style of feedback. In 1963, the teenage Brian May and his father custom-built his signature guitar Red Special, which was purposely designed to feed back.
