Problem: Given the following context:  Since his death, Thomson's work has grown in value and popularity. Group of Seven member Arthur Lismer wrote that he "is the manifestation of the Canadian character". Another contemporaneous Canadian painter, David Milne, wrote to National Gallery of Canada Director H. O. McCurry in 1930, "Your Canadian art apparently, for now at least, went down in Canoe Lake. Tom Thomson still stands as the Canadian painter, harsh, brilliant, brittle, uncouth, not only most Canadian but most creative. How the few things of his stick in one's mind." For Canadian artists Roy Kiyooka and Dennis Lee, he is a "haunting presence" and "embodies the Canadian artistic identity".As of 2015, the highest price achieved by a Thomson sketch was Early Spring, Canoe Lake, which sold in 2009 for CAD$2,749,500. Few major canvases remain in private collections, making the record unlikely to be broken. One example of the demand his work has achieved is the previously lost Sketch for Lake in Algonquin Park. Discovered in an Edmonton basement in 2018, it sold for nearly half a million dollars at a Toronto auction. The increased value of his work has led to the discovery of numerous forgeries on the market.In 1967, the Tom Thomson Art Gallery opened in Owen Sound. In 1968, Thomson's shack from behind the Studio Building was moved to the McMichael Canadian Art Collection in Kleinburg. Many of his works are also on display at the National Gallery of Canada in Ottawa, the Art Gallery of Ontario, and the McMichael Canadian Art Collection in Kleinburg, Ontario. His influence can be seen in the work of later Canadian artists, including Joyce Wieland. In 2004, another historical marker honouring Thomson was moved from its previous location near the centre of Leith to the graveyard in which he is now buried. The grave site has become popular spot for visitors to the area with many fans of his work leaving pennies or art supplies behind as tribute.  answer the following question:  What is the last name of the person to whose work many fans leave pennies or art supplies behind as tribute at the grave site?

A: Thomson


Problem: Given the following context:  Two songs taken from the album ("Mandatory Suicide" and "South of Heaven") have become near constant fixtures in the band's live setlist, notching up appearances on the following: the live DVDs Live Intrusion, War at the Warfield, Still Reigning, Soundtrack to the Apocalypse's deluxe edition's bonus live disc, and the live double album Decade of Aggression.  Lombardo guested with Finnish cellist group Apocalyptica on a live medley of the two tracks at 1998's Headbanger's Heaven festival in the Netherlands. Adrien Begrand of PopMatters described "South of Heaven" as "an unorthodox set opener in theory", noting "the song went over like a megaton bomb detonating the place: dozens of inverted crosses projected behind the high drum riser, the sinewy opening notes kicked in, followed by an overture of bass, cymbal crashes, and tom fills, leading up to the slowly building crescendo" in a concert review. Lombardo remembers listening to a live rendition of "South of Heaven" and thinking, "'Man! There's just so much groove in that song.' To my kids I was saying, 'Listen to that! Listen to how groovy that is!' And it's heavy." A live version of the track featured on the JÄGERMUSIC Rarities 2004 promotional CD, given away to attendees at the Spring 2004 Jägermeister Music Tour. A live rendition of "South of Heaven" was also included on a bonus DVD which came with the group's 2007 re-release of ninth studio album Christ Illusion, shot in Vancouver, British Columbia during 2006's Unholy Alliance tour."Behind the Crooked Cross" is rarely played live as Hanneman hates the track, though King has always wanted to play it "because it's got a cool intro" despite it not being his favorite song. King said "that's fine" when speaking of the situation, noting "there are songs that he wants to play that I always shoot down". "Ghosts of War" isn't King's favorite song either, which he attests "everybody always wants to hear" performed live. He confessed; "I like the ending, you know, I like the big heavy part and I always say, 'Let's...  answer the following question:  What band released "Mandatory Suicide" and "South of Heaven?"

A: Slayer


Problem: Given the following context:  Saint Anthony Falls, the only waterfall of its height on the Mississippi, played an important part in the development of Minneapolis.  The power of the waterfall first fueled sawmills, but later it was tapped to serve flour mills.  In 1870, only a small number of flour mills were in the Minneapolis area, but by 1900 Minnesota mills were grinding 14.1% of the nation's grain.  Advances in transportation, milling technology, and water power combined to give Minneapolis a dominance in the milling industry.  Spring wheat could be sown in the spring and harvested in late summer, but it posed special problems for milling.  To get around these problems, Minneapolis millers made use of new technology.  They invented the middlings purifier, a device that used jets of air to remove the husks from the flour early in the milling process.  They also started using roller mills, as opposed to grindstones.  A series of rollers gradually broke down the kernels and integrated the gluten with the starch.  These improvements led to the production of "patent" flour, which commanded almost double the price of "bakers" or "clear" flour, which it replaced. Pillsbury and the Washburn-Crosby Company (a forerunner of General Mills) became the leaders in the Minneapolis milling industry.  This leadership in milling later declined as milling was no longer dependent on water power, but the dominance of the mills contributed greatly to the economy of Minneapolis and Minnesota, attracting people and money to the region.  answer the following question:  What type of mills were grinding 14.1% of the nation's grain in Minnesota?

A:
flour mills
