Example Input: Question: What was the primary focus of the paper Royster had worked for before the war? Passage:After shakedown along the U.S. East Coast and in the Gulf of Mexico, Jack Miller sailed from Norfolk, Virginia, 13 June 1944, arriving Pearl Harbor 12 July via the Panama Canal Zone and San Diego, California. After more intensive training out of Pearl Harbor, she departed on 24 July screening a convoy to Eniwetok, where she arrived on 2 August. The remainder of the month was spent on patrol and convoy duty. Jack Miller sailed from Eniwetok on 2 September and, after escorting a convoy to Saipan, took up harbor patrol duty there. Antisubmarine patrols, convoy screening, and escort duty kept Jack Miller busy for the next nine months. During this period she sank five mines. In late 1944 Jack Miller came under the command of Lt. Commander Vermont C. Royster; he had served as the White House correspondent of The Wall Street Journal before the war. After the war ended, Lt. Commander Royster would leave the Navy and resume his journalism career at the Wall Street Journal; he would eventually become the paper's editor-in-chief in 1958.

Example Input: Question: Which Robbins song was covered first, "El Paso" or "Big Iron"? Passage:Robbins has been honored by many bands, including the Grateful Dead who covered "El Paso" and Bob Weir & Kingfish who covered "Big Iron". The Who's 2006 album Endless Wire includes the song "God Speaks of Marty Robbins". The song's composer, Pete Townshend, explained that the song is about God deciding to create the universe just so he can hear some music, "and most of all, one of his best creations, Marty Robbins." The Beasts of Bourbon released a song called "The Day Marty Robbins Died" on their 1984 debut album The Axeman's Jazz. Both Frankie Laine and Elvis Presley, among others, recorded versions of Robbins' song "You Gave Me a Mountain", with Laine's recording reaching the pop and adult contemporary charts in 1969. Though Elvis never recorded any of Robbins' songs in the studio, he was a big fan and recorded "You Gave Me a Mountain" live in concert several times; it appeared on 15 Presley albums. Johnny Cash recorded a version of "Big Iron" as part of his American Recordings series, which is included in the Cash Unearthed box set. Cash also recorded other songs by Robbins, including "I Couldn't Keep From Crying", "Kate" and "Song Of The Patriot". He held Robbins in high esteem, having him guest several times on his network TV show. "Big Iron" was also covered by Mike Ness on his album Under the Influences, on which he paid homage to country music artists. The song, originally released on Robbins' 1959 album Gunfighter Ballads and Trail Songs, gained renewed popularity following its use in the video game .
