Example Input: Question: Who was Carpenter's predecessor at the University of Louisiana before he was appointed dean? Passage:He went into medical practice at Jackson, East Feliciana Parish, Louisiana and continued to pursue an interest in the natural sciences. In 1838, he published a study of a submerged forest he discovered near Port Hudson, East Baton Rouge Parish, Louisiana. In 1842, he was a professor of "materia medica" at the University of Louisiana, where he was appointed dean in 1845. In 1844, he published a study on the habit of dirt eating among Negro slaves, and he published several other significant studies. He was a leading proponent of research into disease transportability and transmission as related to importation of disease and outbreak of epidemics. He joined the faculty of the Medical College of Louisiana as Professor of Botany and Geology, and from 1845-1846 he was Dean of the Tulane University School of Medicine. From 1846 through 1848, he was editor of the New Orleans Medical and Surgical Journal. In early 1846, he met Sir Charles Lyell, who said of him: "His knowledge of botany and geology, as well as his amiable manners, made him a most useful and agreeable companion". His botanical collections were published posthumously and several plants were named in his honor, including the rare flowering California Bush Anemone, Carpenteria californica, which was "named in honour of Professor William M. Carpenter (1811-48), a physician from Louisiana, by its discoverer, Major General John Charles Fremont, who collected it on one of his four journeys of exploration in the extreme west of the United States between 1842 and 1848." Carpenter's Groundcherry (Physalis carpenteri Riddell, 1853 ex Rydberg, 1896), a plant in the nightshade family indigenous to Louisiana, and Carpenter's Oak, Quercus carpenteri Riddell, 1853, also indigenous to Louisiana, were named in his honor by fellow naturalist John Leonard Riddell.

Example Output: In 1842, he was a professor of "materia medica" at the University of Louisiana, where he was appointed dean in 1845

Example Input: Question: How long had the prime minister served in that position at the time of the announcement of the anti-piracy measures? Passage:On 28 January 2009, Japan announced its intention of sending a naval task force to join international efforts to stop piracy off the coast of Somalia. The deployment would be highly unusual, as Japan's non-aggressive constitution means Japanese military forces can only be used for defensive purposes. The issue has been controversial in Japan, although the ruling party maintains this should be seen as fighting crime on the high seas, rather than a "military" operation. The process of the Prime Minister of Japan, Taro Aso, giving his approval is expected to take approximately one month. However, the Japanese Maritime Self-Defense Force (JMSDF) and the Japanese government face legal problems on how to handle attacks by pirates against ships that either have Japanese personnel, cargo or are under foreign control instead of being under Japanese control as current Article 9 regulations would hamper their actions when deployed to Somalia. It was reported on 4 February 2009, that the JMSDF was sending a fact-finding mission led by Gen Nakatani to the region prior to the deployment of the Murasame-class destroyer Samidare and the Takanami-class destroyer Sazanami to the coast of Somalia with a 13-man team composed of Japanese Ministry of Defense personnel, with members coming from the Ministry of Foreign Affairs and the JMSDF to visit Yemen, Djibouti, Oman, and Bahrain from 8 to 20 February. Both JMSDF vessels are units of the 8th Escort Division of the 4th Escort Flotilla based in Kure, Hiroshima Prefecture. The JMSDF's special forces unit, the Special Boarding Unit is also scheduled to potentially deploy to Somalia. The SBU has been deployed alongside the two destroyers to Somalia on 14 March 2009. According to JMSDF officials, the deployment would "regain the trust of the shipping industry, which was lost during the war." The JMSDF task force would be deployed off the coast of Somalia for 4 months. In its first mission, the Sazanami was able to ward off pirates attempting to hijack a Singaporean cargo ship. In addition, JMSDF P-3Cs are to be deployed in June from Djibouti to conduct surveillance on the Somali coast. The House of Representatives of Japan has passed an anti-piracy bill, calling for the JMSDF to protect non-Japanese ships and nationals, though there are some concerns that the pro-opposition House of Councillors may reject it. The Diet of Japan has passed an anti-piracy law that called for JMSDF forces to protect all foreign ships traveling off the coast of Somalia aside from protecting Japanese-owned/manned ships despite a veto from the House of Councillors, which the House of Representatives has overturned. In 2009, the Murasame-class destroyer Harusame and the Asagiri-class destroyer Amagiri left port from Yokusuka to replace the two destroyers that had been dispatched earlier in March 2009. Under current arrangements, Japan Coast Guard officers would be responsible for arresting pirates since SDF forces are not allowed to have powers of arrest.

Example Output: On 28 January 2009, Japan announced its intention of sending a naval task force to join international efforts to stop piracy off the coast of Somalia

Example Input: Question: Who did Steve Howe replace someone else as Yes's guitarist? Passage:Hot on the heels of the huge success of CSNY and Led Zeppelin, British band Yes rapidly established themselves as one of the leading groups in the burgeoning progressive rock genre, and their success also played a significant part in establishing the primacy of the long-playing album as the major sales format for rock music in the 1970s. After several lineup changes during 196970, the band settled into its "classic" incarnation, with guitarist Steve Howe and keyboard player Rick Wakeman, who both joined during 1971. Although the extended length of much of their material made it somewhat difficult to promote the band with single releases, their live prowess gained them an avid following and their albums were hugely successful their third LP The Yes Album (1971), which featured the debut of new guitarist Steve Howe, became their first big hit, reaching #4 in the UK and just scraping onto the chart in the US at #40. From this point, and notwithstanding the impact of the punk/new wave movement in the late 1970s, the band enjoyed an extraordinary run of successbeginning with their fourth album Fragile, each of the eleven albums they released between 1971 and 1991 (including the lavishly packaged live triple-album Yessongs) made the Top 20 in the US and the UK, and the double-LP Tales of Topographic Oceans (1973) and Going For The One (1977) both reached #1 in the UK.

Example Output:
