[EX Q]: Question: Which president saw the establishment of the recreation area that contains the lower of the San Juan River? Passage:From there it flows west through the Navajo Nation, turning northwest near Shiprock and its namesake monolith, crossing very briefly back into southwest Colorado (within half a mile (0.8 km) of the Four Corners quadripoint) before entering southeastern Utah. West of Bluff, Utah the river slices through the Comb Ridge and enters a series of rugged winding canyons, often over in depth. The lower of the San Juan River, in a remote portion of the Glen Canyon National Recreation Area, are flooded by Lake Powell, which is formed by Glen Canyon Dam on the Colorado River.

[EX Q]: Question: Which team that Buffalo Braves traded with during the 1976-1977 season was the first to play in the NBA? Passage:The 1976–77 NBA season was the Braves seventh season in the NBA. The Braves were purchased by John Y. Brown, Jr., the former owner of the Kentucky Colonels in the now defunct American Basketball Association for $6.2 million. As part of an agreement with the Braves' former owner, Paul Snyder, Brown would give Snyder money received in player deals to reduce the purchase price. The sell-off began shortly after the season, as the Braves sold newly acquired Moses Malone. Malone was acquired in a trade with the Portland Trail Blazers after the ABA dispersal draft. Malone was now off to the Houston Rockets. The selling of players continued into the season as Bob McAdoo was sold to the New York Knicks. While the deals helped Brown pay virtually nothing for the franchise, it turned a promising franchise into a rebuilding one. Attendance fell off as the Braves finished in 4th place with a 30-52 record. The only spotlight was rookie Adrian Dantley, who captured Rookie of the Year honors with 20.3 points per game. However Dantley himself was traded following the season to the Indiana Pacers for Billy Knight.
