Question: What country did Runyon take photos in initially? Passage:Runyon opened a commercial photography studio in 1910. He initially photographed urban life Brownsville and Matamoros, Tamaulipas and the surrounding terrain of the Rio Grande Valley. In 1913, Runyon began recording the events of the Mexican Revolution, starting with the takeover of the Matamoros garrison by the Constitutional Army under General Lucio Blanco on June 3. He traveled with Blanco's forces to Ciudad Victoria and later Monterrey. In 1915, Runyon was the only professional to photograph two skirmishes by Mexican bandits on American soil, the Norias Ranch Raid and a train derailment near Olmito, Texas. He took more than 2,000 pictures of Fort Brown, which captured troop buildup and mechanization in preparation for World War I. Runyon returned to more traditional subjects in the border region, as well as portraits and postcards, following the end of the war.

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.

Question: What year did the 50th anniversary documentary come out? Passage:Chibnall suggested including a "bonkers" gang of characters picked from around time and space. He felt that Doctor Who could have "collisions of characters that no other show in the world can do", and that it was about finding a "disparate" group of characters who would "bounce" off each other. Nefertiti's decision not to return to her own time fits in with the historical record, as the date and cause of her death are unknown. Chibnall asked to introduce Rory's father, as Amy and Rory would be leaving in four episodes and Rory's family life had not been explored yet. Mark Williams who played Rory's father previously appeared in the Fifth Doctor audio adventure The Eternal Summer. Rupert Graves, who played an Edwardian hunter in this episode, previously worked with Moffat on the BBC series Sherlock. David Bradley's character, Solomon, was modelled on a "well-known nightclub owner with long hair". Chibnall described him as "half businessman, half Somali pirate". Bradley and Williams had previously worked together on the Harry Potter film franchise. Bradley was later cast as the First Doctor William Hartnell for the 50th anniversary documentary drama An Adventure in Space and Time. Comedy duo Mitchell and Webb provided the voices of Solomon's two robots; executive producer Caroline Skinner called the casting choice "perfect". Richard Hope, who played the Silurian Bleytal, previously appeared as Malohkeh in the episodes "The Hungry Earth", "Cold Blood" and "The Wedding of River Song".
