[Q]: Question: How long was Patasse leader of the MLPC? Passage:On 3 March 1982, opposition politician and leader of the MLPC party, Ange-Félix Patassé, returned from exile to the Central African Republic and staged an unsuccessful coup against General André Kolingba (who himself took power in the 1981 coup d'état) with the help of a few military officers, such as General François Bozizé, who accused Kolingba of treason and proclaimed the change of power on Radio Bangui. Four days later, having failed to gain the support of the Central African Armed Forces, Patassé went in disguise to the French Embassy in the Central African Republic to seek refuge. After heated negotiations between the Kolingba government and France, Patassé was allowed to leave for exile in Togo. Bozizé fled to the north of the country with 100 soldiers, before obtaining refuge in France.

[Q]: 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.

[Q]: Question: Which of the singles from Twilight Sad's second studio album charted the highest? Passage:The discography of Scottish rock band The Twilight Sad consists of five studio albums, four compilation albums, fifteen singles, and five extended plays (EPs). The band currently consists of James Graham (vocals, lyrics), Andy MacFarlane (guitar, production), Johnny Docherty (bass), Brendan Smith (keyboards) and Sebastien Schultz (drums). The Kilsyth-based band formed in 2003 and were signed to Fat Cat Records when Alex Knight, co-founder of the label, went to Glasgow to watch the band perform their third gig and signed them on the spot. The band released their debut EP The Twilight Sad in November 2006 in the United States only, followed by their debut album Fourteen Autumns & Fifteen Winters in April 2007, which garnered widespread critical acclaim. The album spawned two singles, "That Summer, at Home I Had Become the Invisible Boy" in April, and "And She Would Darken the Memory" in July. The following year, the band released Here, It Never Snowed. Afterwards It Did, a mini-album of reworked versions of songs from Fourteen Autumns & Fifteen Winters and two non-album tracks, inspired by stripped-down live performances. A collection of live versions and previously unreleased tracks entitled Killed My Parents and Hit the Road was released in December 2008. The Twilight Sad's second studio album, Forget the Night Ahead, was released in September 2009 to further acclaim and marked a shift in the band's direction towards a darker and more streamlined sound. The album produced three singles: "I Became a Prostitute" in August 2009, "Seven Years of Letters" in October 2009, and "The Room" in April 2010. Founding bassist Craig Orzel left the band in February 2010, and the band released The Wrong Car EP in September of that year.
