question:
Question: How many viruses are recognized as the type of virus that poliovirus is? Passage:Poliovirus is an enterovirus. Infection occurs via the fecaloral 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.

question:
Question: How long did Franco rule Spain as dictator? Passage:The 1977 Atocha massacre, a part of neo-fascist terrorism in Spain, was an attack during the Spanish transition to democracy after the death of Franco in 1975, killing five and injuring four. It was committed on January 24, 1977, in an office located on 55 Atocha Street near the Atocha railway station in Madrid, where specialists in labour law, members of the Workers' Commissions (Comisiones Obreras, CCOO) trade union, and of the then-clandestine Communist Party of Spain (PCE) had gathered. The next day, the massacre was defended by a group calling itself Alianza Apostolica Anticomunista (literally Apostolic Anticommunist Alliance, abbreviated Triple A or AAA). The suspects arrested were close to Blas Pinar's Fuerza Nueva far-right party, the Falange-JONS and the Franco Guard. The indignation brought about by the killings accelerated the legalisation of the Communist party, which took place in Easter 1977. On March 24, 1984, the Italian daily Il Messaggero stated that, possibly, Italian neo-fascists had taken part in the shootings, pointing toward some kind of "Black International". This allegation was confirmed by a report from the Italian CESIS, which confirmed that Carlo Cicuttini, who was also involved in the Peteano massacre, took part in the Atocha massacre.
