Example Input: Question: Which son was born first? Passage:Darius was the son of Hystaspes and the grandson of Arsames. Both men belonged to the Achaemenid tribe and were still alive when Darius ascended the throne. Darius justifies his ascension to the throne with his lineage. He claimed he could trace his ancestors back to Achaemenes, even though he was only distantly related. With this in mind, Darius married Atossa, daughter of Cyrus, with whom he had four sons: Xerxes, Achaemenes, Masistes and Hystaspes. He also married Artystone, another daughter of Cyrus, with whom he had two sons, Arsames and Gobryas. Darius married Parmys, the daughter of Bardiya, with whom he had a son, Ariomardus. Furthermore, Darius married Phratagune, with whom he had two sons, Abrokomas and Hyperantes. He also married another woman of the nobility, Phaidyme, the daughter of Otanes. It is unknown if he had any children with her. Before these royal marriages, Darius had married an unknown daughter of his good friend and lance carrier Gobryas from an early marriage, with whom he had three sons, Artobazanes, Ariabignes and Arsamenes. Any daughters he had with her are not known. Although Artobazanes was Darius's first-born, Xerxes became heir and the next king through the influence of Atossa; she had great authority in the kingdom as Darius loved her the most of all his wives.

Example Input: Question: Who was the president of Uptown Records when Mary J. Blige worked for the label as a backing vocalist? Passage:American singer and songwriter Mary J. Blige began her career as a backing vocalist for Uptown Records in the early 1990s. She has released 13 studio albums, eight of which have individually achieved worldwide multi-platinum status. The Queen of Hip-Hop Soul and Queen of R&B (publications often refer to her as both honorific titles), Mary J. Blige is uniquely credited as the first singer to release an album singing over hip-hop beats, which created the genre "hip hop soul" which fuses elements of soul, R&B and gospel style vocals over hip hop beats. Blige's genre-changing sound, in many ways, changed and shaped the sound for modern day R&B and blue-eyed soul artists. In September 1999, Rolling Stone bestowed her first album, What's the 411? (1992), as "genre-creating". Her discography consists of 14 top 10 Billboard 200 studio albums, two live albums, two remix albums and over eighty singles—including more than 20 as a featured artist. In 2009, Billboard magazine ranked Blige as the most successful female R&B/hip-hop artist of the past 25 years. In March 2017, Billboard magazine ranked her 2006 song "Be Without You" as the most successful R&B/hip-hop song of all time, as it spent an unparalleled 75 weeks on the Hot R&B/Hip-Hop Songs chart, 15 of those weeks at number one. In 2011, VH1 ranked Blige as the 80th greatest artist of all time. Moreover, she was ranked 100th on the list of "100 Greatest Singers of All Time" by Rolling Stone magazine. In 2012, VH1 ranked Blige ninth among "The 100 Greatest Woman in Music" listing.
