Passage: Richie Donovan works as a professional thief for Groznyi, a wealthy businessman, to pay off his debt for being smuggled into the U.S. as a child. He pulls off an initially successful diamond heist, but it is botched when he is involved in two separate car accidents. He is given one last chance to pay off his debt by going to Russia to steal a priceless antique cross, locked in a safe in a Moscow penthouse apartment. Richie and his Russian accomplices, brothers Peter and Yuri, recover the cross; but their elevator becomes stuck on the uncompleted 13th floor. Believing the police have stopped the elevator, the thieves take their fellow passengers hostage to negotiate an escape. They agree to send one hostage down; but, when the elevator doors open on the ground floor, the hostage has mysteriously been beheaded. 
The remaining hostages quickly divide into two groups: a Christian group consisting of Sonya, Helena and Katerina, who are later joined by Yuri, and another group consisting of nerdy Dmitry, beautiful Anna, and incompetent security guard Boris.
In the confusion, the Christian group seizes firearms and takes control, shooting Peter. Katerina is sent to stand guard over Richie and the remainder of the hostages, while Sonya takes Yuri to a chamber where he is to sacrificed by a wild man in armor named Alex. Yuri escapes, but he is impaled by one of Alex's traps, complete with disco music and lighting. In his rage, Alex kills Katerina, allowing Richie and the hostages to escape. They discover Alex's lair, where he has been watching everyone using security cameras. A photo reveals that Alex is the twin brother of Sonya, and they both believe themselves to be descendants of Ivan the Terrible. The group splits when Richie and Anna decide to chase after Alex, while Boris and Dmitry prefer to rig the room with various traps they have constructed and wait for Alex to come to them. 
Question: Who are the people who think the authorities are responsible for the elevator stopping, leading them to take hostages?
answer:
Richie.


question:
Passage: As Harvey's interests shifted to the Pyramid, Monte Ne's resort days effectively ended and the number of visitors slowly dwindled. Activities and events at Monte Ne continued, supported by locals who still visited in large numbers. Harvey sold the Hotel Monte Ne. The hotel went through several name changes and owners, becoming the White Hotel circa 1912, the Randola Inn in 1918, the Hotel Frances in 1925, and in 1930 the Sleepy Valley Hotel. Monte Ne's larger hotels continued to be active after they, along with the dance pavilion and Elixir Spring, were foreclosed and sold at public auction. From 1927 to 1932, Missouri Row and Oklahoma Row (often called the Club House Hotels at this point) were home to the Ozark Industrial College and School of Theology, a nonsectarian school run by Dan W. Evans. The hotels housed pupils—Missouri Row for boys, Oklahoma Row for girls—and Oklahoma Row also provided classroom and dining spaces. Evans and his family lived in the tower. The dance pavilion was enclosed and served as the school chapel. In May 1932, following a mortgage foreclosure against the school, school officials were evicted and the property was sold.After he announced the building of the Pyramid, at age 69, Harvey began suffering a series of serious health problems, but continued to work tirelessly. In 1926, blood poisoning in his foot put him in a coma that lasted several days resulting in surgery, and three months of recuperation. In 1929 he and Anna were finally divorced. Three days later Harvey married his long-time personal secretary May Leake. In 1930, he came down with double pneumonia. He was also going blind and needed younger people to read his letters and the newspaper to him. 
Question: What was the original name of the place that was named Randola Inn in 1918?
answer:
Hotel Monte Ne.


question:
Passage: 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. 
Question: What type of mills were grinding 14.1% of the nation's grain in Minnesota?
answer:

flour mills.
