Input: Consider Input: Question: What country did McGillivray return to before taking a trip to Scotland and England? Passage:McGillivray returned to Montreal in 1793 and then took a trip to Scotland and England. He was now a partner in McTavish, Frobisher & Co., who controlled the NWC. With John Gregory, he was sent to manage the company's huge depot at Grand Portage, stirring jealousy among some of the other partners. When Joseph Frobisher retired in 1798, McGillivray took his place. He set up an agency at New York City to get around the East India Company's monopoly enabling them to trade with China. He was closely involved too with the firm of McTavish, Fraser & Co., at London, managed by another relation of his uncle's, John Fraser. In 1803, he helped organize the move of the NWC's main depot from Grand Portage to Thunder Bay. All this time he was dealing with relations with the Hudson's Bay Company and the splinter XY Company that had broken away from the NWC, led by John Richardson.

Input: Consider Input: Question: What is the oldest city that was chosen for filming Aeon Flux? Passage:The screenplay was written by Phil Hay and Matt Manfredi, and directed by Karyn Kusama. It was based on the animated TV series by Peter Chung, who had a minor role in this film version of his work. In the early stages of production, actress Michelle Rodriguez was considered for the part of Æon. She had previously worked with Kusama in Girlfight. Kusama had originally suggested filming in Brasília, the capital of Brazil, because the 20th-century modern architecture of that city fit with her vision of Bregna. The producers rejected the idea because Brasília lacked the infrastructure and technical expertise to support a major film production. After several cities were scouted, Berlin and Potsdam in Germany were chosen for filming. Berlin had several locations that fit into the organic yet structured world of Æon Flux. The crew gained permission to film in several locations that had never allowed such access before, including the Treptow Crematorium, the Adlershof Trudelturm and Windkanal wind tunnel facility, and the Haus der Kulturen der Welt ("House of the World's Cultures"). Additional locations included the Bauhaus Archive and a dissection theatre built in 1790 to train veterinarians, part of the Berlin animal shelter. It was used as the Handler space. Filming was temporarily suspended for a month during September 2004 while Theron recovered from a neck injury she sustained during stunt-work on the tenth day of shooting. She was hospitalized in Berlin for five days and required about six weeks of physiotherapy to recover.

Input: Consider Input: Question: How old were Norman Tindale and Joseph Birdsell when they published their paper about the 12 Negrito tribes? Passage:In a publication of 1941, Norman Tindale, together with the American anthropologist Joseph Birdsell, published a paper suggesting that there were 12 Negrito tribes living on the coastal and rainforest areas around Cairns. The idea had been developed by Birdsell during field work in 1937-8. They were characterized by very short stature, curly hair, and yellowy-brown skin. Six of them were Dyirbal speakers, such as the Jirrbal, Girramay, Gulngai and Djiru within the Murray Upper/Tully Area. Of the others, located further north beyond Cairns, two spoke varieties of Djabugay, and three spoke dialects of Yidin. The remaining tribe were the Mbabaram, whom Tindale took to be strong evidence for his hypothesis because their language, in so far as it had been reported, diverged substantially from the surrounding tongues, and appeared to be wholly atypical, compared to the standard Australian aboriginal languages.
