Example Input: Question: When was the paper started that the Lt. Commander of the Jack Miller in 1944 worked for as a correspondent for before the war? Passage:After shakedown along the U.S. East Coast and in the Gulf of Mexico, Jack Miller sailed from Norfolk, Virginia, 13 June 1944, arriving Pearl Harbor 12 July via the Panama Canal Zone and San Diego, California. After more intensive training out of Pearl Harbor, she departed on 24 July screening a convoy to Eniwetok, where she arrived on 2 August. The remainder of the month was spent on patrol and convoy duty. Jack Miller sailed from Eniwetok on 2 September and, after escorting a convoy to Saipan, took up harbor patrol duty there. Antisubmarine patrols, convoy screening, and escort duty kept Jack Miller busy for the next nine months. During this period she sank five mines. In late 1944 Jack Miller came under the command of Lt. Commander Vermont C. Royster; he had served as the White House correspondent of The Wall Street Journal before the war. After the war ended, Lt. Commander Royster would leave the Navy and resume his journalism career at the Wall Street Journal; he would eventually become the paper's editor-in-chief in 1958.

Example Input: Question: Which team was ranked the highest at the 2009 Pacific Nations Cup? Passage:The 2009 Pacific Nations Cup is a rugby union tournament held between five national sides on the Pacific Rim: Fiji, Japan, Samoa, Tonga and the Junior All Blacks. The New Zealand Māori team that won the tournament last year will no longer take part in this competition because of a decision taken by the New Zealand Rugby Union. Australia A has also decided to pull out due to a similar decision. The inaugural competition was held in 2006. This year the tournament will begin on June 12 and ends on July 3, 2009 and most of the matches will be hosted by Fiji. The awarding of the key international tournament to the Fiji Rugby Union represents a further boost to the continued development of rugby in the region. The two opening round matches will be played outside of Fiji with Samoa hosting the Junior All Blacks in Apia and Tonga entertaining the Fijians in Nukuʻalofa the following day before the tournament moves to Fiji for a 17-day festival of international rugby spread across three match venues: the ANZ National Stadium (Suva), Churchill Park (Lautoka) and Lawaqa Park (Sigatoka).

Example Input: Question: Which school Hodes started teaching at after WWII has a higher enrollment? Passage:Hodes worked as an intern and resident at the Children's Hospital of Philadelphia until 1935, when he moved to Baltimore to take up a position at the Harriet Lane Home of Johns Hopkins Hospital as the dispensary director. In 1936, he developed a method that used ultraviolet light to reduce the infectiousness of viruses, a technique that later was used to create commercial vaccines against rabies and influenza. He became a pediatrician at Johns Hopkins in 1938 while also serving as the medical director of Sydenham Hospital for Communicable Diseases. During an outbreak of diarrhea in 1942, he isolated the first virus known to cause diarrhea, later identified as rotavirus. The same year, he became the first to isolate the measles virus from the brain of a child who had died from measles encephalitis. While stationed in Guam with the U.S. Navy in World War II, he discovered that the Japanese encephalitis virus was spread by mosquitoes. Hodes continued working in Baltimore after World War II, and started teaching at the Johns Hopkins School of Medicine and School of Hygiene, as well as the University of Maryland School of Medicine.
