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: Did TJ Maxx make a profit the year Famous-Barr was re-branded as Macy's? Passage:Northpark Mall opened in 1972, on Range Line Road on the east side of Joplin. At the time, the mall was anchored by Montgomery Ward to the north, JCPenney to the south, and local chain Newman's the middle. Other stores included Walgreens, McCrory's, Ramsay's department store, For All Bible (which is still in business), Wyatts cafeteria, as well as many other stores. Newman's became Heer's in 1987, the same year that a new wing was built, and the mall received its first renovation. The new wing extended easterly from the JCPenney store. This new wing included two new anchors, Famous-Barr and Venture. The renovation also brought a food court as well as a new 5 screen cinema. In 1994, Heer's closed, and Famous-Barr moved its men's wear and home goods to the former Heer's space. That same year Sears built a store adjacent to Montgomery Ward, moving from an older store near downtown Joplin. In 1998 the mall received a minor renovation, changing only the color scheme. After the closure of the Venture chain in 1998, its anchor at the mall was converted to Shopko, but it closed in the early 2000s following the closure of Montgomery Ward in 2001. Both Famous-Barr locations were re-branded as Macy's in 2006. Montgomery Ward remained vacant until mid-2007, when its space was split between TJ Maxx and Steve & Barry's, the latter of which closed in 2008 and was replaced by Vintage Stock. In 2006 the mall received its first major renovation in nearly 20 years, changing the color scheme, adding all new lighting and floor tiles, and renovating the food court to a route 66 theme.

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: Which of the publication where Pink Floyd gained important coverage due to Jenner and King's diverse array of social connections was published first? Passage:Pink Floyd, then an unknown band, began to receive paid bookings including at the Marquee Club in March 1966 where they were watched by Jenner. The band played mostly rhythm and blues songs, but Jenner was impressed with the strange acoustic effects that Barrett and Wright created during their performance. Jenner traced Waters and Mason to their flat, and with his business partner and friend Andrew King was subsequently invited to become their manager. Although the pair had little experience of the music industry, they shared an appreciation of music, as well as a childhood history. Using inherited money they set up Blackhill Enterprises and purchased new instruments for the band, as well as equipment which included a Selmer PA system. Under their guidance, Pink Floyd began performing on London's underground music scene, notably at a venue booked by the London Free School in Notting Hill, as well as the notorious "Games For May" concert at London's Queen Elizabeth Hall on 12 May 1967, an event set up by both Jenner and King. Jenner and King's diverse array of social connections were meritorious, gaining the band important coverage in The Financial Times and The Sunday Times. Jenner's voice can be heard at the start of Pink Floyd's 1967 "Astronomy Domine", the opening track on the album The Piper at the Gates of Dawn (UK edition).
