Example Input: Passage: After thief Alex Cardo gets caught and betrayed by his partner in crime John while stealing an ancient Jian in Thailand, he soon finds himself imprisoned and beaten. One of the guards, Demon, is particularly upset by Alex's appearance and tortures him whenever he gets the opportunity. Alex finds one friend and mentor in the jailhouse, Master Sun, who teaches him a superior fighting style called "Iron Hand". When a "best of the best kumite" is to take place, Demon gets an invitation. Now Master Sun and Alex need to find a way to let Alex take part in the kumite, too.
The final fight pits Alex and Demon together.  At first, and for a long time, Demon has the upper hand in terms of strength and fighting ability.  When Alex is down, he takes one last look at Master Sun and uses the "Iron Hand" against his opponent, severely damaging and defeating Demon.  Alex is the winner, and as part of deals previously made, Master Sun is freed from prison, and so is Alex. 
Question: What is the full name of the person who learns the "Iron Hand" fighting style?
Example Output: Alex Cardo.

Example Input: 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?
Example Output: Vine.

Example Input: Passage: The pay-what-you-want release, the first for a major act, made headlines worldwide and sparked debate about the implications for the music industry. According to Mojo, the release was "hailed as a revolution in the way major bands sell their music", and the media's reaction was "almost overwhelmingly positive". Time called it "easily the most important release in the recent history of the music business" and Jon Pareles of The New York Times wrote that "for the beleaguered recording business Radiohead has put in motion the most audacious experiment in years". The NME wrote that "the music world seemed to judder several rimes off its axis", and praised the fact that everyone, from fans to critics, had access to the album at the same time on release day: "the kind of moment of togetherness you don’t get very often." Singer Bono of U2 praised Radiohead as "courageous and imaginative in trying to figure out some new relationship with their audience".The release also drew criticism. Trent Reznor of Nine Inch Nails thought it did not go far enough, calling it "very much a bait and switch, to get you to pay for a Myspace-quality stream as a way to promote a very traditional record sale". Reznor independently released his sixth album Ghosts I-IV under a Creative Commons licence the following year. Singer Lily Allen called the release "arrogant", saying: "[Radiohead have] millions of pounds. It sends a weird message to younger bands who haven't done as well. You don't choose how to pay for eggs. Why should it be different for music?" In the Guardian, journalist Will Hodgkinson wrote that Radiohead had made it impossible for less successful musicians to compete and make a living from their music. Kim Gordon of Sonic Youth told the Guardian the release "seemed really community-oriented, but it wasn't catered towards their musician brothers and sisters, who don’t sell as many records as them. It makes everyone else look bad for not offering their music for whatever."Radiohead's managers defended the release as "a solution for Radiohead, not the industry", and doubted "it would work the same way [for Radiohead] ever again". Radiohead have not used the pay-what-you-want system for subsequent releases. In February 2013, Yorke told the Guardian that though Radiohead had hoped to subvert the corporate music industry with In Rainbows, he feared they had instead played into the hands of content providers such as Apple and Google: "They have to keep commodifying things to keep the share price up, but in doing so they have made all content, including music and newspapers, worthless, in order to make their billions. And this is what we want?". 
Question: What companies possibly benefited from the band who was called "arrogant" by Lily Allen decision to subvert the corporate music industry?
Example Output:
Google.
