[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. The San Juan joins the Colorado in San Juan County, Utah at a point about to the north of Navajo Mountain and northeast of Page, Arizona.

[Q]: Question: How many players recorded a Gordie Howe hat trick the year Lucic signed with the Bruins? Passage:In the 2007 off-season, Lucic signed an entry-level contract with the Bruins on August 2. He had been chosen as the Giants' next team captain, but made the Bruins' 2007–08 opening roster out of training camp. He played in his first career NHL game on October 5, 2007, a 4–1 loss to the Dallas Stars, in which he fought opposing forward Brad Winchester. His first goal came a week later on October 12 against Jonathan Bernier, a game winner, in an 8–6 win against the Los Angeles Kings. By also fighting Kings forward Raitis Ivanāns and notching an assist, he recorded a Gordie Howe hat trick (an unofficial statistic constituting a goal, an assist and a fight in one game). Unsure of whether the Bruins would keep him or return him to junior, he stayed in a downtown hotel in Boston to start the season. However, Lucic made enough of an impression during his first set of games with the Bruins, showing grit and consistent willingness to fight (he recorded 13 fighting majors in his rookie season), that they decided to keep him in the lineup. Bruins management informed the Giants prior to Lucic's tenth game, accounting for the NHL's nine-game maximum for junior-eligible players to stay with their NHL club without initiating their contract. He was chosen to participate in the 2008 NHL YoungStars Game and finished his rookie campaign with eight goals and 27 points. Towards the end of the season, he was voted by Bruins fans for the team's Seventh Player Award for exceeding expectations. Matched up against the first-seeded Montreal Canadiens in the opening round, Lucic scored his first Stanley Cup playoff goal in Game 3 on April 13, 2008. He finished his first NHL post-season with two goals as the Bruins were eliminated by the Canadiens in seven games.

[Q]: Question: What year did the revolt take place that was masterminded by someone that Maqrizi studied theology under? Passage:Al-Maqrīzī was born in Fatimid Cairo and spent most of his life in Egypt, When he presents himself in his books he usually stops at the 10th forefather although he confessed to some of his close friends that he can trace his ancestry to Al-Mu‘izz li-Dīn Allāh -first Fatimid caliph in Egypt and the founder of al-Qahirah- and even to Ali ibn Abi Talib. He was trained in the Hanafite school of law. Later, he switched to the Shafi'ite school and finally to the Zahirite school. Maqrizi studied theology under one of the primary masterminds behind the Zahiri Revolt, and his vocal support and sympathy with that revolt against the Mamluks likely cost him higher administrative and clerical positions with the Mamluk regime. The name Maqrizi was an attribution to a quarter of the city of Baalbek, from where his paternal grandparents hailed. Maqrizi confessed to his contemporaries that he believed that he was related to the Fatimids through the son of al-Muizz. Ibn Hajar preserves the most memorable account: his father, as they entered the al-Hakim Mosque one day, told him "My son, you are entering the mosque of your ancestor." However, his father also instructed al-Maqrizi not to reveal this information to anyone he could not trust; Walker concludes:
