[Q]: Question: How big is the National Park that the Yellowstone River flows northward through? Passage:The river rises in northwestern Wyoming in the Absaroka Range, on the Continental Divide in southwestern Park County. The river starts where the North Fork and the South Fork of the Yellowstone River converge. The North Fork, the larger of the two forks, flows from Younts Peak. The South Fork flows from the southern slopes of Thorofare Mountain. The Yellowstone River flows northward through Yellowstone National Park, feeding and draining Yellowstone Lake, then dropping over the Upper and Lower Yellowstone Falls at the head of the Grand Canyon of the Yellowstone within the confines of the park. After passing through the Black Canyon of the Yellowstone downstream of the Grand Canyon, the river flows northward into Montana between the northern Absaroka Range and the Gallatin Range in Paradise Valley. The river emerges from the mountains near the town of Livingston, where it turns eastward and northeastward, flowing across the northern Great Plains past the city of Billings.

[Q]: Question: How long did the person serving as Malyan Prime Minister during 1958 serve in office? Passage:Relations with the former state of South Vietnam were established when South Vietnam recognised the Federation of Malaya's independence on 1957. From that point, Malaya provided aid to the South Vietnamese regime in its fight against the Viet Cong and North Vietnamese army. Malayan Prime Minister Tunku Abdul Rahman made a first visit on 1958 which was reciprocated twice by the South Vietnamese President Ngô Đình Diệm on 28–31 January 1958 and in October 1961. By 1963, when Malaya transformed into Malaysia (with an additional territory in the island of Borneo), the main government in Kuala Lumpur worried the influence of North Vietnamese communists would threaten its existence in accordance to the Domino theory, thus changing its position to become very supportive of the American involvement in the Vietnam War as Malaysia had also experienced a communist insurgency of its own. Tunku Abdul Rahman then expressed these concerns in December 1966 and called on the United States and the United Kingdom to provide increased logistical support to war efforts in Vietnam. Malaysia hosted training courses in public administration and jungle warfare for government officials, and provided motorcycles to bolster the South Vietnamese police and military logistical capabilities. Towards the end of the Vietnam War in 1975, Malaysia closed its embassy in Saigon in two stages; first it withdrew the embassy dependants on 12 April 1975, before a complete closure 16 days later—two days before the fall of Saigon. Malaysia had also extended recognition to the short-lived Provisional Revolutionary Government of the Republic of South Vietnam within days of its formation in May 1975, citing Malaysia's impartial position on political ideology and social system.

[Q]: Question: When did the vote on Norick's plan occur? Passage:By 1992, the city was in such dire need of improvement that it was losing jobs, population, and even air carriers to more attractive cities. With this in mind, Mayor Ron Norick pushed through a massive plan for capital improvements throughout downtown called the Metropolitan Area Projects Plan, or MAPS. MAPS called for a five-year, one-cent sales tax to fund a new ballpark, a canal through Bricktown, a new central library, a large indoor arena, renovations to the fairgrounds and the civic center, and a series of low water dams on the North Canadian River to make it attractive and accessible to small boats. Though still stinging from the failure of "urban renewal", the people of Oklahoma City passed the measure, eventually raising over 1 billion dollars for improvements to the city and bringing life back to the central city.
