Example Input: 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.

Example Input: Question: Which of these organizations was founded first? Passage:On March 19, 2018, the children's picture book Marlon Bundo's A Day in the Life of the Vice President was released. It was written by Charlotte and illustrated by Karen. The picture book tells the story of Bundo observing the Vice President's daily activities. Pence said that they'd "love to do something for a sequel". As a "jab" at Mike Pence's opposition to LGBT rights in the United States, a parody of the picture book titled A Day in the Life of Marlon Bundo, authored by Last Week Tonight with John Oliver comedy writer Jill Twiss and illustrated by Gerald Kelley, was published by Chronicle Books a day before. In the parody book, Bundo falls in love with a rabbit named Wesley, but a character resembling Mike Pence decrees that male rabbits cannot marry each other. Proceeds from the picture book go to benefit art therapy programs, and The A21 Campaign, which works to combat human trafficking; Charlotte Pence picked the latter charity because of her prior experience with the organization. Proceeds from the parody book go to benefit The Trevor Project, which runs a crisis hotline for members of the LGBTQ community, and AIDS United. The picture book and the parody book reached the fourth and the first spot, respectively, on Amazon's best-selling books list. As of late March 2018, Pence's book and Twiss's book sold approximately 100,000 and 400,000 copies, respectively, and were respectively No. 5 and No. 6 Children's Picture Books on The New York Times Best Seller list. Pence reacted positively to the parody book, saying:
