Passage: Harry Glicken (March 7, 1958 – June 3, 1991) was an American volcanologist. He researched Mount St. Helens in the United States before and after its 1980 eruption, and was very distraught about the death of fellow volcanologist David A. Johnston, who had switched shifts with Glicken so that the latter could attend an interview. In 1991, while conducting avalanche research on Mount Unzen in Japan, Glicken and fellow volcanologists Katia and Maurice Krafft were killed by a pyroclastic flow. His remains were found four days later, and were cremated in accordance with his parents' request. Glicken and Johnston remain the only American volcanologists known to have died in volcanic eruptions.
Despite a long-term interest in working for the United States Geological Survey, Glicken never received a permanent post there because employees found him eccentric. Conducting independent research from sponsorships granted by the National Science Foundation and other organizations, Glicken accrued expertise in the field of volcanic debris avalanches. He also wrote several major publications on the topic, including his doctoral dissertation based on his research at St. Helens titled "Rockslide-debris Avalanche of May 18, 1980, Mount St. Helens Volcano, Washington" that initiated widespread interest in the phenomenon. Since being published posthumously by Glicken's colleagues in 1996, the report has been acknowledged by many other publications on debris avalanches. Following his death, Glicken was praised by associates for his love of volcanoes and commitment to his field. 
Question: What is the last name of the person who was regarded as eccentric?
Glicken.

Passage: "Halo" was composed by Ryan Tedder, lead vocalist of OneRepublic, together with Evan "Kidd" Bogart and Beyoncé. In an interview for HitQuarters, Kidd narrated the events that led to writing the song. OneRepublic canceled their tour after Tedder had broken his Achilles tendon and had undergone surgery. The following day, the band sent Tedder to Los Angeles. There, he and Kidd were socializing when Tedder expressed his desire to write a song. Kidd was initially opposed to the idea because Tedder was supposed to be recuperating, but the pair went to Tedder's studio. During the writing sessions, singer Ray LaMontagne was the primary inspiration for "Halo". Kidd suggested they create a song in the style of LaMontagne's "Shelter" for Beyoncé and her husband Jay-Z, and proposed the title "Halo" after hearing Tedder play "angelic" chords. They wrote the song in three hours.According to Simon Cowell, owner of the music production company Syco Entertainment, Bogart and Tedder intended "Halo" for his client, singer Leona Lewis, who could not record the song because of her tight schedule. Cowell was upset that Beyoncé chose to record the song. David Balls, editor of the British media website Digital Spy, asked Tedder during an interview whether "Halo" had initially been written for Lewis. Tedder answered that he had only tentatively offered the track to Lewis, after Beyoncé waited a long time before recording it. He commented:
There was this huge scandal that originally "Halo" was meant to go to Leona. That was never the case ... That song was written for Beyoncé. What happened was that Beyoncé waited long enough to record that song ... I thought this would be a brilliant first single for Leona, which it would have ... What I did was foolishly say to Leona's camp, "I have it on hold for another A-list artist and I'm pretty sure they'll take it, but if they don't, I just want to know if you like it enough to consider it". I sent it to them and they flipped on it. They loved it and instantly said they wanted to do it. I was like, "Wait, wait, wait, no, it's not free yet!". 
Question: What is the first name of the person who broke his Achilles tendon?
Ryan.

Passage: John Chisum, a virtuous, patriarchal land baron, locks horns with greedy Lawrence Murphy, who will stop at nothing to get control of the trade and even the law in Lincoln County, New Mexico Territory.
Chisum is an aging rancher with an eventful past and a paternalistic nature towards his companions and community. Murphy, a malevolent land developer, plans to take control of the county for his own personal gain.
The story begins with Murphy's men tipping off Mexican rustlers who plan to steal Chisum's horses. Chisum and his sidekick James Pepper stop the bandits with help from a newcomer to the area, William H. Bonney, also known as "Billy the Kid". A notorious killer, Billy has been given a chance to reform by Chisum's philanthropic British neighbor, rancher Henry Tunstall. Billy also falls for Chisum's newly arrived niece, Sallie.
Murphy is buying up all the stores in town and using his monopoly to push up the prices. He appoints his own county sheriff and deputies. He also brings in a lawyer, Alexander McSween, whose principles lead him to switch sides and seek work with Chisum and Tunstall. The two ranchers set up their own bank and general store in town under McSween's control.
Chisum's land and cattle remain targets. Murphy's men attempt to steal Chisum's cattle before he can sell them to the United States Army. Chisum's ranch hands are warned by Pat Garrett, a passing buffalo hunter. Garrett agrees to help Chisum and soon befriends Bonney. Together they foil an attack by Murphy's men on the wagons bringing in provisions for the new store. 
Question: What is the nickname of the person who helps Chisum and his sidekick stop the bandits?

Billy the Kid.
