Example Input: Question: How deep is the body of water in Eagle Mountain? Passage:FM 1220 begins at an intersection with SH 183 in the Far Greater Northside area of Fort Worth. The highway travels in a northwestern direction along Azle Avenue through a residential area and runs along the northern edge of Sansom Park before entering Lake Worth. In Lake Worth, FM 1220 has a junction with I-820 and turns north onto Boat Club Road near Lake Worth High School. The highway travels in a northern direction near several subdivisions, running between Lake Worth and Marine Creek Reservoir, before re-entering Fort Worth near Saginaw. FM 1220 continues to run near several subdivisions in far northwest Fort Worth and turns west north of an intersection with Park Drive, then enters the town of Eagle Mountain. The highway runs through the town and runs close to Eagle Mountain Lake. West of Eagle Mountain, the Boat Club Road designation leaves the highway, with FM 1220's local designation becoming Morris Dido Newark Road. The highway runs in a northwestern direction near the eastern shore of Eagle Mountain Lake with state maintenance ending at Peden Road at the southern boundary of Pecan Acres; Morris Dido Newark Road continues past Peden Road for another to FM 718 near Newark.

Example Input: Question: What year did construction begin on the dam that the river passes through before Afterbay Dam? Passage:The Bighorn River begins as the Wind River in the Rocky Mountains at Wind River Lake, near Two Ocean Mountain and the summit of Togwotee Pass. The Wind River flows southeast receiving the east fork of the Wind River from the north, and enters the Wind River Basin, flowing past Dubois and Johnstown, to Riverton, where it receives the Little Wind River. The river then changes direction to the northeast and then the north, flowing into Boysen Reservoir, which is formed by Boysen Dam. Below the dam it enters the Wind River Canyon, where the river narrows and forms many rapids. At the end of the canyon the Wind River widens out in an area called the Wedding of the Waters where it becomes the Bighorn River and enters the Bighorn Basin. The Bighorn continues northward, passing through Thermopolis, Worland, and Basin. At Greybull it receives the Greybull River, and about north of that confluence it enters Bighorn Lake, where it is joined by the Shoshone River. North of the confluence with the Shoshone, the reservoir narrows as the river enters the Bighorn Canyon, where it crosses into Montana. At the end of the canyon, the river passes through Yellowtail Dam and Afterbay Dam. The river turns to the northeast and enters the Great Plains. At Hardin the river is joined by the Little Bighorn River. Approximately downriver from the Little Bighorn, in Big Horn County, the Bighorn empties into the Yellowstone.

Example Input: Question: In what year did the NFL lock its official out in June? Passage:The NFL locked out its officials in June. As a result, the first three weeks of the season were played with replacement officials. The lack of regular officials came to a head in the Week 3 Monday night game between Green Bay and Seattle. The game was a defensive affair as Packers led, 12–7, in the closing moments of the game. On the final play Seattle quarterback Russell Wilson threw a Hail Mary pass toward the end zone. Seattle receiver Golden Tate and Packers defender M. D. Jennings each grabbed hold of the ball. In the process, one official signaled touchdown while another signaled touchback. Simultaneous possession was the final ruling which gave Seattle the touchdown and the win. However, the nearby officials missed Tate pushing Cornerback Sam Shields with both hands and causing a pass interference penalty in the process. The game's aftermath included major discussion and focus on the play forcing the NFL to reach a settlement with the regular officials. The loss also hurt the Packers in the playoff race as the team finished 11–5 behind the 11–4–1 San Francisco 49ers. The loss mattered as Green Bay had to travel to San Francisco in the Divisional Round of the playoffs. A win would have assured a 1st round bye for Green Bay. The game was called the Fail Mary
