Q: Question: Which player that Schüttler beat in the 2009 Chennai Open had won the most tournaments that year? Passage 1:Born in Tacoma, Washington to an attorney and his wife who were active New Deal Democrats, Elizabeth Binns wanted to be a lawyer from a young age. Her father sometimes allowed her to skip classes in order to watch him try cases; she graduated from the local public high school at age 16. She then attended Stanford University and graduated with a Bachelor of Arts degree in 1942 at the age of 19. Because so many men were away during World War II, Binns was admitted to the Stanford Law School, and completed one year before marrying Robert L. Fletcher, who was soon assigned to fly anti-aircraft blimps out of Lakehurst, New Jersey. They started a family, and moved back to Lakewood, Washington, after the war. With her parents' assistance in caring for their four young children (and renting out their own house to live in Lakewood), Fletcher resumed her legal education after a decade, now commuting to Seattle to study at the University of Washington School of Law. In 1956 she graduated at the top of her law school class, with a Bachelor of Laws.
 Passage 2:His 2009 season Schüttler started off at the Chennai Open, beating Prakash Amritraj 6–2, 4–6, 6–1. In the second round, he beat Simon Greul 6–4, 6–2, and in the quarterfinals Björn Phau, 6–2, 7–5. Unfortunately Schuettler had to withdraw from his semifinal match against Somdev Devvarman because of a wrist injury. He also withdrew from the tournament in Sydney. At the Australian Open, he was seeded 30th but lost in the first round to Israeli Dudi Sela 1–6, 6–2, 6–4, 6–4. He also participated in the doubles with Lu Yen-hsun, but they were defeated by Łukasz Kubot and Oliver Marach. In the first round in Rotterdam, he lost to Mario Ančić. He played the Open 13 in Marseille, defeating Laurent Recouderc in the first round 6–1, 6–4.
 Passage 3:Timur's first appearance in the Caucasus was a response to Khan Tokhtamysh's marauding inroad into Northern Iran through the Caucasian lands in 1385. This marked an outbreak of outright hostility between the two Islamic monarchs. Timur responded by launching a full-scale invasion of the small frontier countries, which lay between the western border of his emerging empire and Tokhtamysh's khanate. After having overrun Azerbaijan and Kars, Timur marched into Georgia. The official history of his reign, Zafarnama, represents this campaign in Georgia as a jihad. Timur set out from Kars and assailed Samtskhe, the southernmost principality within the Kingdom of Georgia later in 1386. From there, he marched against Tbilisi which the Georgian king Bagrat V had fortified. The city fell on November 21, 1386, and King Bagrat V was captured and converted to Islam at sword point. The Georgian Chronicle and Thomas of Metsoph mention the apostasy of the king but represent it as a clever ruse which enabled him to earn a degree of trust of Timur. Bagrat was given some 12,000 troops to reestablish himself in Georgia whose government was run by Bagrat's son and co-ruler George VII during his father's absence at Timur's court. The old king, however, entered in secret negotiations with George who ambushed Bagrat's Islamic escort, and freed his father.
