Q: Passage: When Ella Finch and her sister Kate inherit $30,000 each just after the end of World War I, Ella becomes dissatisfied with her dull life in South Bend, Indiana, and with Kate's butcher boyfriend Willis. She is convinced she can rectify both problems by taking Kate to New York City. Her wisecracking cigar salesman husband Ernie is unable to change her mind, so he reluctantly goes along, postponing a promotion at work by claiming to his boss, A. J. Gluskoter, that his wife is sick and needs a stay at a sanitarium. On the train, they meet New Yorker Francis Griffin. Ernie is less impressed with him than his wife and sister-in-law.
In New York, Ella helps Katie try to win over Francis, but it turns out that he is actually infatuated with Ella. She has to punch him to fend off his unexpected advances. Ernie shows up later and knocks him down too.
Ella then rents an apartment. Ella meets their wealthy neighbor, Lucius Trumball, who invites them all over for drinks. Ella is delighted, but Kate is not pleased when she discovers that Trumball is much older than her. Later she finds out he is also married when his wife returns unexpectedly from Timbuktu.
They return to the hotel they stayed at before, where they meet Herbert Daley, who owns race horses. At the track, Daley persuades them to bet on his horse. It wins, but then Daley's jockey, Sid Mercer, shows interest in Kate, much to Daley's annoyance. Kate secretly sees Sid while also going to the track with Daley with Ella and Ernie. Daley returns early from a trip and catches Sid kissing Kate, but Kate assures him there is nothing serious going on, and they become engaged. 
Question: What is the last name of the person that Ella tries to help Katie win over?

A: Griffin.

Q: Passage: Increasing tourist and commercial interest in petrified wood during the late 19th century began to alarm residents of the region. In 1895, the Arizona Territorial Legislature asked the U.S. Congress to create a petrified forest national park. Although this first attempt failed, in 1906 the Antiquities Act signed by President Theodore Roosevelt was used to create the Petrified Forest National Monument. Between 1934 and 1942, the federal Civilian Conservation Corps built road, trails, and structures in the monument, and the government acquired additional land in the Painted Desert section. The monument became a national park in 1962. Six years after the signing of the Wilderness Act in 1964 by President Lyndon B. Johnson, wilderness areas (where human activity is limited), were designated in the park. In 2004, President George W. Bush signed a bill authorizing the eventual expansion of the park from 93,353 acres (about 146 mi2 or 378 km2) to 218,533 acres (about 341 mi2 or 884 km2). Theft of petrified wood is still a problem. Despite a guard force of seven National Park Service rangers, fences, warning signs, and the threat of a $325 fine, an estimated 12 short tons (11,000 kg) of the fossil wood is stolen from the Petrified Forest every year.Jessee Walter Fewkes, the first archeologist to visit Puerco Ruin, predicted in the late 19th century that it would yield many artifacts. Conservationist John Muir conducted the first excavations of the ruin in 1905–06. Although he did not publish his findings, he urged the federal government to preserve Petrified Forest. Professional archeological work in the park began in the early 20th century when Walter Hough conducted excavations at Puerco Ruin and other sites.  In 1919, a phytosaur skull was discovered near Blue Mesa in the Petrified Forest and sent to the Museum of Paleontology in Berkeley, California.  In 1921, Annie Alexander, founder of the museum, visited Blue Mesa to collect more of the phytosaur and other specimens; this led to further excavations by paleontologist Charles Camp.  Since then, more than 250 fossil sites have been documented in the park. In the 1930s, the Civil Works Administration funded research in the park by archeologists H.P. Mera and C.B. Cosgrove. A National Park Service resurvey of the Petrified Forest in the early 1940s identified most of the large sites with stone ruins, and subsequent surveys since 1978 have identified a total of more than 600 artifact sites, many of them small. Research in paleontology and archeology continues at the park in the 21st century. 
Question: Who urged the federal government to preserve Petrified Forest?

A: John Muir.

Q: Passage: In the 1980s, a young guitarist called Euronymous forms a black metal band called Mayhem, the first of the genre in their country of Norway, with Necrobutcher on bass, and  Manheim on drums. Manhein leaves and is soon replaced by new drummer Hellhammer and they recruit a new vocalist from Sweden called Dead, who exhibits self-destructive behavior, which he portrays during their live shows by cutting himself and bleeding on the audience, and throwing pig heads at the "posers". At a show filmed by their friend Metalion, the band meets a fan named Kristian, whom Euronymous initially looks down on.
While home alone, Dead uses his personal knife to cut his arms and throat, and then uses Euronymous' shotgun to shoot himself in the forehead, leaving behind a suicide note. Euronymous returns home and finds the body but instead of calling the police, he takes photos of the body and moves the knife and shotgun around. After Dead's body is taken away, Euronymous gives necklaces to the other band members which he claims are pieces of Dead's skull; this disgusts Necrobutcher, prompting him to leave the band.
Soon after, Euronymous starts his own black metal record label and opens a record shop called Helvete, which becomes a social hub for black-metallers like Metalion, Fenriz of Darkthrone, Faust of Emperor, and Kristian (who is now calling himself Varg Vikernes) of Burzum. They become known as the "Black Circle". After being mocked by an ego-driven Euronymous, Varg uses his anti-Christian beliefs as motivation to burn down a local church. When approached by Varg concerning his status as the leader of the Black Circle, Euronymous burns down a church with Faust and Varg accompanying.
Euronymous recruits Varg as bassist, a guitarist called Blackthorn and a Hungarian vocalist, Attila Csihar, to record Mayhem's first album, De Mysteriis Dom Sathanas. A power dispute between Varg and Euronymous arises. 
Question: Whose shotgun did Dead use to shoot himself in the forehead?

A:
Euronymous.
