Question: Question: When did the pitcher who Bay hit a grand slam off of in September retire? Passage:Bay got off to a slow start to the 2012 season, finishing spring training with no home runs or RBI, and his regular season, which was derailed further by a broken rib suffered while making a diving catch in the April 23 game against the San Francisco Giants. When Bay returned from the DL on June 8, 2012 against the New York Yankees, he went 0-for-3 with one strikeout. He continued to go 0-for-16 in his return from the DL through June 12, before hitting a single on June 13 against the Tampa Bay Rays. In a home game against the Cincinnati Reds on June 15, Bay left the game in the second inning after crashing into the left field wall and suffering a concussion while attempting to catch a fly ball by Jay Bruce that became an inside-the-park home run. He was subsequently placed on the DL again, and returned again on July 17 against the Washington Nationals. On September 2, Bay hit a grand slam off of Miami Marlins pitcher Mark Buehrle in the first inning of a 5–2 Mets win. Bay also hit a home run off of Buehrle on September 22 in a 4–3 Mets win. Bay finished the 2012 season with a .165 batting average, 8 home runs and 20 RBI.

Question: Question: How many soldiers did Britain send to World War I the year Roebuck arrived on the Western Front? Passage:As a boy, Roebuck worked as a trammer and after being sentenced to one month's imprisonment for stealing a watch in 1904, he enlisted in the York and Lancaster Regiment. Over the next seven years, he was stationed in India and Ireland and was promoted to lance corporal, but was demoted back to private in 1910 for "misconduct". He married in 1908 and had two children. Roebuck was discharged into the reserves in 1912 and likely returned to work as a miner prior to becoming a professional footballer in 1913. After Britain's entry into the First World War in August 1914, he was called up by the York and Lancaster Regiment and arrived on the Western Front in September 1914. On 18 October 1914, Roebuck recorded as "presumed dead" after an attack near Beaucamps-Ligny during the Race to the Sea. His death was confirmed by two comrades in January 1915. Roebuck is commemorated on the Ploegsteert Memorial to the Missing.

Question: Question: How many viruses are recognized as the type of virus that poliovirus is? Passage:Poliovirus is an enterovirus. Infection occurs via the fecal–oral route, meaning that one ingests the virus and viral replication occurs in the alimentary tract. Virus is shed in the feces of infected individuals. In 95% of cases only a primary, transient presence of viremia (virus in the bloodstream) occurs, and the poliovirus infection is asymptomatic. In about 5% of cases, the virus spreads and replicates in other sites such as brown fat, reticuloendothelial tissue, and muscle. The sustained viral replication causes secondary viremia and leads to the development of minor symptoms such as fever, headache, and sore throat. Paralytic poliomyelitis occurs in less than 1% of poliovirus infections. Paralytic disease occurs when the virus enters the central nervous system (CNS) and replicates in motor neurons within the spinal cord, brain stem, or motor cortex, resulting in the selective destruction of motor neurons leading to temporary or permanent paralysis. In rare cases, paralytic poliomyelitis leads to respiratory arrest and death. In cases of paralytic disease, muscle pain and spasms are frequently observed prior to onset of weakness and paralysis. Paralysis typically persists from days to weeks prior to recovery.
