Problem: Safin was born in Moscow to Tatar parents, Mubin ("Mikhail") Safin and Rauza Islanova. He speaks Russian, English, and Spanish as well as his native Tatar. His parents are former tennis players and coaches. His younger sister, Dinara, is a former world number one professional tennis player and silver medalist at the 2008 Olympic Games in Beijing.

A succession of injuries hindered Safin's progress throughout his career.  In 2003, he missed the majority of the season due to a wrist injury.  During the 2005 clay-court season, Safin suffered a knee injury, which he played through all the way up to Wimbledon with the help of pain killers and anti-inflammatories. Safin was subsequently defeated in the early rounds of each of the seven tournaments he played between the Australian Open and the French Open, culminating in an early round defeat at the French Open. Safin made a surprise finals appearance at the Wimbledon tune-up tournament in Halle on grass. He lost the final narrowly to the defending champion, Federer. He only played one tournament in the summer hard-court season, in Cincinnati, where he lost in the quarterfinals to Robby Ginepri. He also missed the Tennis Masters Cup.  Injuries continued to bother Safin in 2006. Although Safin made appearances at the 2006 ATP Masters tournaments at Indian Wells, Miami, Monte Carlo, Rome and Hamburg, his ranking plummeted to as low as No. 104. He began to recover in time for the 2006 US Open, in which Safin defeated Argentine David Nalbandian, who was then world No. 4 in a riveting second-round match. Safin then lost in the fourth round to former world No. 2 German Tommy Haas, also in a fifth-set tiebreaker. Positive performances at the Thailand Open, where he was narrowly edged out by No. 7 seed, James Blake, and the Kremlin Cup in Moscow, the first all-Russian final at that event, losing to compatriot, Ukrainian-born Nikolay Davydenko, marked Safin's recovery. Despite the injury, Safin still posted 7 wins against top ten players in 2006, fourth-most on the ATP tour behind just Federer (19), Nadal (10), and Blake (8).

Has he needed surgery for any of his injuries?

Answer with quotes: 

Background: James Buchanan Jr. was born in a log cabin in Cove Gap, Pennsylvania (now Buchanan's Birthplace State Park), in Franklin County, on April 23, 1791, to James Buchanan, Sr. (1761-1821), a businessman, merchant, and farmer, and Elizabeth Speer, an educated woman (1767-1833). His parents were both of Ulster Scottish descent, the father having emigrated from Milford, County Donegal, Ireland, in 1783. One of eleven siblings, Buchanan was the oldest child in the family to survive infancy.
Context: In March 1860, the House created the Covode Committee to investigate the administration for evidence of offenses, some impeachable, such as bribery and extortion of representatives in exchange for their votes. The committee, with three Republicans and two Democrats, was accused by Buchanan's supporters of being nakedly partisan; they also charged its chairman, Republican Rep. John Covode, with acting on a personal grudge (since the president had vetoed a bill that was fashioned as a land grant for new agricultural colleges, but was designed to benefit Covode's railroad company). However, the Democratic committee members, as well as Democratic witnesses, were equally enthusiastic in their pursuit of Buchanan, and as pointed in their condemnations, as the Republicans.  The committee was unable to establish grounds for impeaching Buchanan; however, the majority report issued on June 17 exposed corruption and abuse of power among members of his cabinet, as well as allegations (if not impeachable evidence) from the Republican members of the Committee, that Buchanan had attempted to bribe members of Congress in connection with the Lecompton constitution. (The Democratic report, issued separately the same day, pointed out that evidence was scarce, but did not refute the allegations; one of the Democratic members, Rep. James Robinson, stated publicly that he agreed with the Republican report even though he did not sign it.)  Buchanan claimed to have "passed triumphantly through this ordeal" with complete vindication. Nonetheless, Republican operatives distributed thousands of copies of the Covode Committee report throughout the nation as campaign material in that year's presidential election.
Question: Who was the Covode Committee named after?
Answer: was designed to benefit Covode's railroad company

Question:
Judith Butler FBA (born February 24, 1956) is an American philosopher and gender theorist whose work has influenced political philosophy, ethics and the fields of third-wave feminist, queer and literary theory. Since 1993, she has taught at the University of California, Berkeley, where she is now Maxine Elliot Professor in the Department of Comparative Literature and the Program of Critical Theory. She is also the Hannah Arendt Chair at the European Graduate School. Butler is best known for her books Gender Trouble:
Judith Butler was born in Cleveland, Ohio, to a family of Hungarian-Jewish and Russian-Jewish descent. Most of her maternal grandmother's family perished in the Holocaust. As a child and teenager, she attended both Hebrew school and special classes on Jewish ethics, where she received her "first training in philosophy". Butler stated in a 2010 interview with Haaretz that she began the ethics classes at the age of 14 and that they were created as a form of punishment by her Hebrew school's Rabbi because she was "too talkative in class". Butler also stated that she was "thrilled" by the idea of these tutorials, and when asked what she wanted to study in these special sessions, she responded with three questions preoccupying her at the time: "Why was Spinoza excommunicated from the synagogue? Could German Idealism be held accountable for Nazism? And how was one to understand existential theology, including the work of Martin Buber?"  Butler attended Bennington College and then Yale University where she studied philosophy, receiving her B.A. in 1978 and her Ph.D. in 1984. She spent one academic year at Heidelberg University as a Fulbright-Scholar. She taught at Wesleyan University, George Washington University, and Johns Hopkins University before joining University of California, Berkeley, in 1993. In 2002 she held the Spinoza Chair of Philosophy at the University of Amsterdam. In addition, she joined the department of English and Comparative Literature at Columbia University as Wun Tsun Tam Mellon Visiting Professor of the Humanities in the spring semesters of 2012, 2013 and 2014 with the option of remaining as full-time faculty.  Butler serves on the editorial board or advisory board of academic journals including JAC: A Journal of Rhetoric, Culture, and Politics and Signs: Journal of Women in Culture and Society.
