Question: What was the real name of the wrestler Buffalo defeated in order to win his first title in Osaka Pro? Passage:In April 1999, Yamada joined the Osaka Pro Wrestling promotion, where he began wrestling under a mask as Black Buffalo, a character inspired by the Osaka Kintetsu Buffaloes baseball team. He made his debut for the promotion at its first event on April 29, where he, Dick Togo and Violencia, forming the villainous alliance Legion of Violence (LOV), were defeated in a six-man tag team main event by Masato Yakushiji, Naohiro Hoshikawa and Super Delfin. Buffalo kept teaming with Togo for the rest of the year. On November 21, Buffalo won his first title in Osaka Pro, when he defeated Super Delfin for the UWF Super Welterweight Championship, only to lose it back to him seven days later. In early 2000, LOV was joined by Daio Quallt and Policeme~n, replacing Violencia. On May 1, Buffalo and Togo defeated Super Delfin and Super Demekin in the finals to win the 1st Anniversary Tag Tournament. In September, Buffalo took part in the inaugural Tenno-zan tournament, where he made it to the semifinals, before being eliminated by Super Delfin. After Dick Togo left Osaka Pro at the end of 2000, LOV was disbanded and replaced by the new group, FLUXxx, as a member of which Buffalo formed a new tag team named Infinity with Tsubasa. After reaching the semifinals of the 2001 Osaka Tag Festival, Buffalo and Tsubasa defeated Super Delfin and Takehiro Murahama on July 21 to win the vacant Osaka Pro Wrestling Tag Team Championship. They would lose the title to Murahama and Kaiju Zeta Mandora on August 24. The following October's Tenno-zan saw a repeat of the previous year's tournament as Buffalo was eliminated in the semifinals by Super Delfin. On January 27, 2002, Buffalo, Tsubasa and Gamma defeated Super Delfin, Super Demekin and Takehiro Murahama to win the Trios Cup Tournament. On August 25, Buffalo and Tsubasa regained the Osaka Pro Wrestling Tag Team Championship by defeating the Kishiwada Gurentai (Big Boss MA-G-MA and Daio Quallt). After a five-month reign, they would lose the title to Jyushin Thunder Liger and Takehiro Murahama on February 1, 2003.

Question: In what city and state did the music festival take place where DeVotchKa's performance was considered a breakout event? Passage:Originally a backing band for burlesque shows, in their early years DeVotchKa also toured with burlesque performer and model Dita Von Teese. Numerous nationwide tours in support of self-released records earned the band an underground following. Their song "How It Ends" introduced the band to a wider audience after being featured in the trailer for Everything Is Illuminated, in a Gears of War 2 trailer called "The Last Day", and in an episode of Everwood (Season 4). Their performance at the 2006 Bonnaroo music festival was considered a breakout event. In between tours, the band was picked by first time film directors Jonathan Dayton and Valerie Faris to score Little Miss Sunshine, a 2006 film that would go on to garner four Academy Award nominations. DeVotchKa, along with composer Mychael Danna, composed and performed the majority of the music for the film's soundtrack and were nominated for a 2006 Grammy Award for Best Compilation Soundtrack. The main song, "The Winner Is", was also used in a commercial by the French-based environment and energy company Suez and the Dutch pension fund PGGM.

Question: Who signed the Treaty of Sevres? Passage:The intention declared in the royal speech at the opening of the Chamber of resuming the war against Kemal was supported by an official report issued on January 10 of a renewal of the Greek offensive to the northeast of Smyrna and in the Brussa area, and the same day the Greeks occupied Belejik. On the following day the Greek Liberal organ Patris published a letter from Nice, where Venizelos was residing at the time, confirming the Greek statesman's final decision to retire from politics. This decision was naturally not displeasing to the supporters of King Constantine, who a little later found another cause for jubilation when the king of Italy received the newly appointed Greek minister to Rome (January 13). Thus Italy was the first among foreign Allied and neutral powers to recognize King Constantine. But the enthusiasm was soon damped by the joint representations made on the 20th to the Greek government by the British and French ministers in Athens on the transformation of the Chamber into a National Assembly. This action by the two Allied governments was declared to be based on the rights of the powers in question as guarantors of the constitution of Greece, rights which they considered as still existent, since the Treaty of Sèvres, in which they were surrendered, had not yet been ratified by all the signatories. Early in February the Allied Supreme Council invited the Greek and Turkish governments to attend a conference to be held in the latter part of the month in London with the object of bringing about peace between the two countries. The invitation was coldly received in Athens, and was the cause of a split in the Dimitrios Rallis cabinet on the score of wounded personal vanities. Dimitrios Gounaris, minister of war, the real leader of the Constantino faction, who, in deference to Allied public opinion, which had stigmatized him as a pro-German, had after the defeat of the Venizelists been compelled to renounce his claims to the premiership in favor of the less compromised Rallis, after being also refused the presidency of the Greek delegation to the London conference, resigned, bringing about a ministerial crisis.
