PROBLEM: Passage: Biographer Hannah Fink estimated that Oliver produced 290 works over a career of 22 years. Of these, public art works are Oliver's best known sculptures. These include Eyrie, created for Adelaide's Hyatt Hotel in 1993, and Magnolia and Palm, commissioned in 1999 by the Sydney Botanical Gardens, as part of the Sydney Sculpture Walk. That same year, Big Feathers was commissioned for the Queen Street Mall in Brisbane. It comprises two large feather-shaped forms suspended above the pedestrian precinct, representing "Queen Street's history of parades as well as the mall's connection between earth and sky".In 2000, Oliver's piece Entwine was a finalist in the inaugural Helen Lempriere National Sculpture Award, while in the following year, Oliver won the University of New South Wales inaugural sculpture commission competition, with her three-metre-high Globe. Other success followed, when Trace was selected for the National Gallery of Australia's 2002 National Sculpture Prize exhibition.In August 2002 she was one of five artists shortlisted by the Australian Government for a project to produce a public artwork celebrating the centenary of women's suffrage in Australia.By the 2000s most of Oliver's output constituted commissioned pieces, whether public or private. The most substantial of these is Vine, a 16.5 metre high sculpture installed as part of the $400 million refurbishment of the Sydney Hilton. Taking twelve months to create and requiring a budget of up to half million dollars, the work was completed in 2005. The sculpture was fabricated from 380 kilograms of aluminium, and assembled by a team of eight Croatian welders.By 2006, Oliver had held 18 solo exhibitions of her work, half of them at Roslyn Oxley9 Gallery, which represented her throughout her career as a sculptor. Only one of those solo exhibitions was held outside Australia: a 1992 exhibition at Auckland City Gallery. However, Oliver was represented in numerous international group shows, including five during the period 1983 to 1984, around the time she completed her master's degree in London. Four of the group shows at that time were in the United Kingdom; the fifth was at the Museum of Traditional Industries in Kyoto. Subsequent international group shows included 'Five Australian Artists' at Brest's Centre Culturale in 1988, the year she undertook an artist's residency in that city. Later group shows of which Oliver was part included 'Prospect '93' at the Frankfurter Kunstverein, 'Systems End: Contemporary Art in Australia', which exhibited in several east Asian galleries in 1996, and the Beijing International Biennale in 2003. 
Question: What is the name of the sculpture that was fabricated from 380 kilograms of aluminium, and assembled by a team of eight Croatian welders?

SOLUTION: Vine.

PROBLEM: Passage: Both Surfer Rosa and Steve Albini's production of the album have been influential on alternative rock, and on grunge in particular. Nirvana's Kurt Cobain cited Surfer Rosa as the basis for Nevermind's songwriting. When he first heard the album, Cobain discovered a template for the mix of heavy noise and pop he was aiming to achieve. He remarked in 1992 that he "heard songs off of Surfer Rosa that I'd written but threw out because I was too afraid to play them for anybody." Cobain hired Albini to produce Nirvana's 1993 album In Utero, primarily due to his contribution to Surfer Rosa. The Smashing Pumpkins' Billy Corgan described Surfer Rosa as "the one that made me go, 'holy shit'. It was so fresh. It rocked without being lame." Corgan was impressed by the album's drum sound, and acknowledged that The Smashing Pumpkins used to study the record for its technical elements. Musician PJ Harvey said that Surfer Rosa "blew my mind," and that she "immediately went to track down Steve Albini." Cobain listed Surfer Rosa as number 2 of the top 50 albums he thought were most influential to Nirvana's sound in his journal in 1993.People connected with the band were impressed by the record. Ivo Watts-Russell recalled: "I remember when I first heard Surfer Rosa thinking, 'I didn't know the Pixies could sound like The Fall.' That was my immediate reaction, in other words, incredibly raw." Gary Smith, who at the time was in a disagreement with the band, admitted he "was really happy that they had made such a forceful, aggressive, record." Dinosaur Jr.'s J Mascis, comparing the record to the later Pixies albums Bossanova and Trompe le Monde, said he thought that Steve Albini's production "sounded way better than the other ones."In 1991, as Pixies were recording Trompe le Monde, Albini described his impressions of Pixies during the recording of Surfer Rosa to the fan magazine Forced Exposure: "A patchwork pinch loaf from a band who at their top dollar best are blandly entertaining college rock. Their willingness to be 'guided' by their manager, their record company and their producers is unparalleled. Never have I seen four cows more anxious to be led around by their nose rings." Albini later apologized for his remarks, saying, "to this day I regret having done it. I don't think that I regarded the band as significantly as I should have.". 
Question: What is the first name of the person who was hired for their work with Surfer Rosa?

SOLUTION: Steve.

PROBLEM: Passage: In Guazacapán, now a municipality in Santa Rosa, Pedro de Alvardo described his encounter with people who were neither Maya nor Pipil, speaking a different language altogether; these people were probably Xinca. At this point Alvarado's force consisted of 250 Spanish infantry accompanied by 6,000 indigenous allies, mostly Kaqchikel and Cholutec. Alvarado and his army defeated and occupied the most important Xinca city, named as Atiquipaque, usually considered to be in the Taxisco area. The defending warriors were described by Alvarado as engaging in fierce hand-to-hand combat using spears, stakes and poisoned arrows. The battle took place on 26 May 1524 and resulted in a significant reduction of the Xinca population. Alvarado's army continued eastwards from Atiquipaque, seizing several more Xinca cities. Tacuilula feigned a peaceful reception only to unsuccessfully raise arms against the conquistadors within an hour of their arrival. Taxisco and Nancintla fell soon afterwards. Because Alvarado and his allies could not understand the Xinca language, Alvarado took extra precautions on the march eastward by strengthening his vanguard and rearguard with ten cavalry apiece. In spite of these precautions the baggage train was ambushed by a Xinca army soon after leaving Taxisco. Many indigenous allies were killed and most of the baggage was lost, including all the crossbows and ironwork for the horses. This was a serious setback and Alvarado camped his army in Nancintla for eight days, during which time he sent two expeditions against the attacking army. Jorge de Alvarado led the first attempt with thirty to forty cavalry and although they routed the enemy they were unable to retrieve any of the lost baggage, much of which had been destroyed by the Xinca for use as trophies. Pedro de Portocarrero led the second attempt with a large infantry detachment but was unable to engage with the enemy due to the difficult mountain terrain, so returned to Nancintla. Alvarado sent out Xinca messengers to make contact with the enemy but they failed to return. Messengers from the city of Pazaco, in the modern department of Jutiapa, offered peace to the conquistadors but when Alvarado arrived there the next day the inhabitants were preparing for war. Alvarado's troops encountered a sizeable quantity of gathered warriors and quickly routed them through the city's streets. From Pazaco Alvarado crossed the Río Paz and entered what is now El Salvador.After the conquest of the Pacific plain, the inhabitants paid tribute to the Spanish in the form of valuable products such as cacao, cotton, salt and vanilla, with an emphasis on cacao. 
Question: What three things did the Xinca use to fight the conquistadors?

SOLUTION:
spears.
