Question: Who won championship in the year that Unai Emery named Rakitic captain? Passage:At the beginning of the 2013–14 La Liga season, coach Unai Emery named Rakitić as the new Sevilla captain. Since the beginning of the season, he was one of the most prominent players of the league, scoring the first goal and assisting for the second in a 3–2 away loss against Barcelona on 14 September. In the two last games of September, he scored two goals in a 1–4 away win over Rayo Vallecano, and assisted for the draw 1–1 goal against Real Sociedad. In the final three games of October, Rakitić scored a goal in a 2–0 home win against SC Freiburg, a 2–1 home win over Almería and two goals in a 7–3 loss at the Santiago Bernabéu Stadium against Real Madrid. In the third and fourth games of November, he contributed an assist in away 1–3 win against Espanyol, and two more respectively in a 4–0 home win against Sevilla rivals Betis. In the last game of December, he assisted in a 1–2 away win against Villarreal, helping Sevilla reach a top ten position after a disappointing start of the season, as well attracting attention from other international clubs. In the first game of the 2014 calendar year, he scored in a 3–0 home win against Getafe. In January, he scored two more La Liga goals for Sevilla against Atlético Madrid and Levante, respectively, while also missing a penalty kick in the latter fixture. These performances earned him a La Liga Player of the Month award.

Question: Where was the person born who plays Ernst Stavro Blofeld ? Passage:The story sees Bond pitted against the global criminal organisation Spectre and their leader Ernst Stavro Blofeld (Christoph Waltz). Bond attempts to thwart Blofeld's plan to launch a global surveillance network, and discovers Spectre and Blofeld were behind the events of the previous three films. The film marks Spectre and Blofeld's first appearance in an Eon Productions film since 1971's Diamonds Are Forever; a character resembling Blofeld had previously appeared in the 1981 film, For Your Eyes Only, but, because of the Thunderball controversy, he is not named, nor is his face shown. Several James Bond characters, including M, Q and Eve Moneypenny return, with new additions Léa Seydoux as Dr. Madeleine Swann, Dave Bautista as Mr. Hinx, Andrew Scott as Max Denbigh and Monica Bellucci as Lucia Sciarra.

Question: What is the birthplace of the man who launched the Kharkov counter-strike on February 19th? Passage:As the German Sixth Army was encircled in Stalingrad, the Red Army undertook a series of wider attacks against the rest of Army Group South. These culminated on 2 January 1943 when the Red Army launched Operation Star and Operation Gallop, which between January and early February broke German defenses and led to the Soviet recapture of Kharkov, Belgorod, Kursk, as well as Voroshilovgrad and Izium. The Soviet victories caused participating Soviet units to over-extend themselves, though this was largely due to Manstein's strategy of controlled retreat towards the Dneiper. Freed on 2 February by the surrender of the German Sixth Army, the Red Army's Central Front turned its attention west and on 25 February expanded its offensive against both Army Group South and Army Group Center. Months of continuous operations had taken a heavy toll on the Soviet forces and some divisions were reduced to 1,000–2,000 combat effective soldiers. On 19 February, Field Marshal Erich von Manstein launched his Kharkov counterstrike, using the fresh II SS Panzer Corps and two panzer armies. Manstein benefited greatly from the massive air support of Field Marshal Wolfram von Richthofen's Luftflotte 4, whose 1,214 aircraft flew over 1,000 sorties per day from 20 February to 15 March to support the German Army, a level of airpower equal to that during the Case Blue strategic offensive a year earlier.
