[EX Q]: Question: How long has Nakayama been president of Sega when he was looking for a flagship series to compete with Mario? Passage:In 1990, Sega president Hayao Nakayama sought a flagship series to compete with Nintendo's Mario franchise along with a character to serve as a company mascot. Several character designs were submitted as part of a contest. Among the designs was an egg-shaped man wearing pajamas who resembled Theodore Roosevelt, drawn by Naoto Ohshima. According to Ohshima, the resemblance to Roosevelt was unintentional, saying he was influenced by a variety of characters. Retrospective sources have indicated Ohshima based the character on Humpty Dumpty and Mario. The Roosevelt lookalike did not win the contest; rather, another Ohshima character, a hedgehog named Mr. Needlemouse—later renamed Sonic—prevailed. As development of the Sega Genesis game Sonic the Hedgehog progressed, however, programmer Yuji Naka and the rest of Sonic Team thought the rejected design was excellent and deserved inclusion in the game. Since the character could not be the protagonist, the team retooled him into the game's main antagonist.

[EX 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.

[EX Q]: Question: Which of the two teams that played in the Bodyline series has the best record overall? Passage:George Alfred Hele (16 July 1891 – 28 August 1982) was an Australian cricket umpire who umpired 16 Test matches between 1928 and 1933. He was most famous for his role in the infamous Bodyline series, played between Australia and England during the latter team's 1932–33 tour of Australia. From Adelaide, South Australia, Hele played club cricket, but retired at an early age after an injury. He also played Australian rules football for the West Torrens Football Club in the South Australian Football League (SAFL). He took up umpiring at club level in 1918, and progressed to first-class level shortly after, debuting as an umpire during the 1920–21 Australian cricket season. As South Australia's primary umpire, Hele served in almost every first-class match in the state during the 1920s, both in Sheffield Shield matches involving the South Australian cricket team and in state matches against touring international sides.
