Example Input: Question: What is the county seat of the county where the Blue Whale is located? Passage:I-44/SH-66 cut diagonally through the city of Tulsa. In West Tulsa, Interstate 244 branches off to serve the downtown area. I-44/SH-66 follow the Skelly Drive through midtown. The highways interchange with the Okmulgee Beeline, the US-75 freeway before crossing the Arkansas River. The next freeway interchange is with the Broken Arrow Expressway, carrying US-64 and SH-51, followed by the Mingo Valley Expressway, carrying US-169 I-244 then merges with I-44 at its eastern terminus. I-44/SH-66 cross into Rogers County and the suburb of Catoosa, serving as the southern terminus of SH-167. SH-66 then splits off from I-44, initially following an old alignment of the Interstate where it transitioned into the Will Rogers Turnpike. SH-66 then downgrades to an expressway as it passes through Catoosa, home of the Blue Whale. Northeast of Catoosa, near Verdigris, SH-66 intersects SH-266 at its eastern terminus.

Example Input: Question: Which band that Yokam released cover songs from has more members, The Clash or Queen? Passage:Johnny Cash once cited Yoakam as his favorite country singer. Chris Isaak called him as good a songwriter as ever put a pen to paper. Time dubbed him "A Renaissance Man" and Vanity Fair declared that "Yoakam strides the divide between rock's lust and country's lament." Along with his bluegrass and honky-tonk roots, he has written or covered many Elvis Presley-style rockabilly songs, including his covers of Queen's "Crazy Little Thing Called Love" in 1999 and Presley's "Suspicious Minds" in 1992. He recorded a cover of The Clash's "Train in Vain" in 1997, a cover of the Grateful Dead song "Truckin'", as well as Cheap Trick's "I Want You to Want Me". He has never been associated only with country music; on many early tours, he played with hardcore punk bands like Hüsker Dü, and played many shows around Los Angeles with roots/punk/rock & roll acts. His middle-period-to-later records saw him branching out to different styles, covering rock & roll, punk, 1960's, blues-based "boogie" like ZZ Top, and writing more adventurous songs like "A Thousand Miles From Nowhere". In 2003, he provided background vocals on Warren Zevon's last album The Wind.

Example Input: Question: Which European opera company presented by DGOS has been in operation for the greatest amount of years? Passage:The Dublin Grand Opera Society (DGOS) was founded in 1941 by Captain (later Colonel) William O'Kelly and a group of opera enthusiasts with John McCormack as its patron. The shows were cast with local singers and a volunteer chorus. Initially the music was provided by the orchestra of the Irish Army music school, and later by the Radio Eireann Symphony Orchestra. The Society put on two one-week seasons of opera throughout the years of World War II. After the war ended the DGOS presented performances by European opera companies such as the Opera-Comique, Hamburg Opera and the Netherlands Opera. From the mid 1950s to 1966, the Society, concentrated on Italian opera with the help of sponsorship from the Italian government. During that time numerous Italian stars and rising stars of the day appeared there, including Luciano Pavarotti who sang in Rigoletto, La traviata, and La bohème. The Italian sponsorship ended in 1966, but the Arts Council of Ireland and the Bord Fáilte (Ireland's tourist board) continued to provide guarantees for any financial losses. New opera companies were brought in, including the Romanian National Opera and the Prague National Theatre.
