PROBLEM: 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.

PROBLEM: Question: What team did Matt Geiger play for before the 76ers? Passage:The 1998–99 NBA season was the 76ers 50th season in the National Basketball Association, and 36th season in Philadelphia. After a four-month lockout wiped out half the season, the Sixers signed free agents Matt Geiger and George Lynch, while re-signing former 76ers forward Rick Mahorn. At midseason, they traded second-year forward Tim Thomas and Scott Williams to the Milwaukee Bucks for Tyrone Hill. The Sixers recorded their first winning month in five years winning 8 of 13 games in February, on their way to making the playoffs for the first time in eight years with a 28–22 record, third in the Atlantic Division. Allen Iverson led the league in scoring averaging 26.8 points per game, and was selected to the All-NBA First Team. In the first round of the playoffs, the Sixers defeated the 3rd–seeded Orlando Magic in four games, but were swept in the semifinals by the Indiana Pacers in four straight games. Following the season, Mahorn retired after making his second stint with the Sixers.
