Example Input: Question: What is the singer that Hank mocks most famous song? Passage:Publicist Jolene (Denise Richards) has a tense relationship with rock musician Hank (James Stevenson), who is planning to marry journalist Rose (Lauren German). As the lead singer of the band Modern Apes, Hank performs "mocking [and] self-congratulatory" versions of Barry Manilow's music. According to Tatiana Morales of CBS News, people compared Jolene to Amanda Woodward from Melrose Place. Muir characterized Jolene as a maneater, and Phil Gallo of Variety viewed her as "a devilish character with a dark soul". On the other hand, Shandy Casteel of PopMatters described Rose as the girl next door. David Bianculli of the New York Daily News cited her as the show's lead character. In the pilot episode, Rose receives the ashes of her ex-boyfriend Billy (Dylan Bruno), but it is revealed he is alive when he re-enters the characters' lives. Jolene believes that Rose had ruined her relationship with Billy, and responds by plotting to take Hank as "a means to nasty retaliation". As part of the show's comedy, Rose imagines people singing pop music to her.

Example Input: Question: Of the 8 fraternities at the University of Alabama in the 1800s, which was the oldest on a national level? Passage:Greek letter organizations (GLOs) first appeared at the university in 1847 when two men visiting from Yale University installed a chapter of Delta Kappa Epsilon. When DKE members began holding secret meetings in the old state capitol building that year, the administration strongly voiced its disapproval. Over a few more decades, 7 other fraternities appeared at UA: Alpha Delta Phi in 1850, Phi Gamma Delta in 1855, Sigma Alpha Epsilon in 1856 (this was the founding chapter), Kappa Sigma in 1867, Sigma Nu in 1874, Sigma Chi in 1876, and Phi Delta Theta in 1877. Anti-fraternity laws were imposed that year, but were lifted in the 1890s. Women at the university founded the Zeta chapter of Kappa Delta sorority in 1903. Alpha Delta Pi soon followed.
