Question: Who did Alberto Del Rio win the eponymous match against? Passage 1:After shakedown in the Caribbean Sea, Saint Paul departed Boston, Massachusetts, on 15 May 1945 and headed for the Pacific. From 8–30 June, she underwent training out of Pearl Harbor and sailed on 2 July to join Task Force 38 (TF 38). This fast carrier striking force completed replenishment at sea on 23 July and then proceeded to launching points for strikes against Honshū, Japan's largest island. From 24 July to 10 August, Saint Paul screened the carriers as they delivered heavy air strikes on Kure, Kobe, and the Tokyo area in southern Honshū, then at Maizuru and various airfields in northern Honshū. During this period, Saint Paul also bombarded industrial targets: first on textile mills at Hamamatsu during the night of 29 July, and then on 9 August at iron and steel works in Kamaishi, firing the war's last hostile salvo from a major ship. Typhoon warnings canceled air operations from 11–14 August. Then, those launched that morning were recalled, after peace negotiations gave promise of Japan's surrender. On 15 August, all offensive operations against Japan were stopped.
 Passage 2:With the outbreak of the Russo-Turkish War in August 1787, Russian Empress Catherine the Great laid out her plans to incite revolts across Ottoman Greece. Proclamations calling the Greek clergy to lead a war of liberation against the Ottomans were printed in September 1787 and February 1788. In March, Admiral Samuel Greig and Major-General Ivan Zaborovsky were tasked with signing alliances and facilitating revolts among the Christian populations in Dalmatia, Albania and Greece. The Russian consulate in the Heptanese activated its network of sleeper agents who had originally been recruited before the Orlov revolt. Louitzis Sotiris and Himariot Panos Bitsilis begin recruiting soldiers in the area of Epirus, while Antonis Psaros and Lambros Katsonis built a small naval force in Italy. For the most part Russian plans did not materialize as the Baltic Fleet failed to reach the Mediterranean Sea. Without its assistance most of Russia's local allies refused to take part in the rising.
 Passage 3:At the Royal Rumble, Alberto Del Rio won the eponymous match to earn himself a World Championship match at WrestleMania. He subsequently announced he would wrestle for the World Heavyweight Championship, held at the time by Edge. Edge was then embroiled in a feud with Dolph Ziggler and his on-screen ex-wife Vickie Guerrero, who was also scripted to be dating Ziggler. The week before the Elimination Chamber Edge and Kelly Kelly defeated Ziggler and LayCool, causing Guerrero to fire Kelly Kelly. Kelly Kelly was rehired by Teddy Long, Vickie was attacked by Kelly, who was only to be stopped by Laycool, in turn was stopped by Trish Stratus. On the final episode of SmackDown before the pay-per-view, acting general manager Guerrero stripped Edge of the championship and awarded it to Ziggler, only for Theodore Long, the real general manager, to give Edge a return match which he won. After this, Long fictitiously and Kayfabe Ziggler leaving an open spot in the Elimination Chamber match (which was subsequently filled by Big Show). The other participants were Kane, Rey Mysterio, Wade Barrett and Drew McIntyre. After that event, Edge and Kelly Kelly defeated Drew McIntyre and Vickie Guerrero thus making Theodore Long fire Vickie Guerrero as the official consultant of SmackDown.
