Question: Question: Who is in charge of the city Couceiro arrived in in 1889? Passage:Paiva Couceiro arrived in Luanda, Angola on September 1, 1889, and was immediately appointed commander of the Irregular Cavalry Squadron in the village of Humpata (which was originally created by Artur de Paiva to combat bands of guerrillas along the plain of Moçâmedes). He did not remain at this outpost for long; apparently he was unsatisfied with his subordinates, their methods and inferior level of discipline, but was able to utilize them in a campaign to retrieve missing cattle, instead of hiring local Boer mercenaries, which had been the custom. By January he was in the village of Belmonte, in Bié, on a mission that would take him along the Cuando River, to Cuito and then to the Lialui along the Zambezi River (a trek of thousands of kilometers across savannah), in order to negotiate with Lewanika, chief of the Barotze tribe. The growth of the Portuguese occupation force in the Angolan interior was part of the administration's attempted to implement their Pink Map to explore and expand their serfdom over the peoples of the central-African interior. After some resistance, the colonial administration began a military campaign to pacify groups that had resisted initial token gestures of friendship and gifts, a process that Paiva Couceiro participated in energetically. For the chief's recognition of Portuguese sovereignty over his territories, Paiva Couceiro brought with him a colonels tunic and sword, textiles, gold, velvet, boxes of Porto wine and arms, which were to be delivered in 300 crates when the Governor of Angola canceled the project.

Question: Question: Who is the wife of the Tigers pitcher who was name World Series MVP? Passage:The 2012 World Series was the championship series of Major League Baseball's (MLB) 2012 season. The 108th edition of the World Series, the series was a best-of-seven playoff between the National League (NL) champion San Francisco Giants and the American League (AL) champion Detroit Tigers; the Giants won in a four-game sweep. This marked the Giants' seventh World Series title in franchise history, their second in San Francisco (they won five in New York), and their second in a three-year period (2010–2012). Their World Series sweep was the first by an NL team since the Cincinnati Reds swept the Oakland Athletics in the 1990 series and the first NL sweep not by the Reds since 1963, when the Los Angeles Dodgers swept the New York Yankees. This was also the first World Series since 1988 to feature both of that year's League MVPs (Miguel Cabrera for the AL and Buster Posey for the NL). The Giants' Pablo Sandoval, who in Game 1 tied a record by hitting three home runs in one World Series game, two off Tigers' ace pitcher Justin Verlander, was named the World Series Most Valuable Player (MVP).
