[EX Q]: Question: How long did the war in which Massey joined the Canadian Army last? Passage 1:The Morris Brothers were born in Old Fort, North Carolina. Originally, they began performing as a trio together with a third brother, George Morris. In 1933, Zeke moved to Concord and joined J. E. Mainer's Crazy Mountaineers He made his first recordings with the Mountaineers in August 1935 för Bluebird Records. Four years later, in 1937, Wiley and Zeke along with banjo player Wade Mainer did some radio work in the North Carolina towns of Asheville and Raleigh. In April 1938, The Morris Brothers, fiddler Homer Sherrill and banjo player Joel Martin, calling themselves the Smilin' Rangers, performed at radio station WBTM in Danville, Virginia. In September 1938, Zeke recorded with Charlie Monroe as a replacement for Bill Monroe just after the Monroe Brothers had disbanded. The same year, Zeke's musical career came to a halt when he went to work in a cotton mill in Gastonia. In 1939, the brothers moved to Asheville and WWNC radio, where they resumed their career. After World War II they retired and opened an auto repair business. Between 1938 and 1939, the Morris Brothers made 36 recordings for RCA Victor.
 Passage 2:After leaving Union Station and crossing the Los Angeles River, the line follows the San Bernardino Freeway and El Monte Busway until just after the Cal State L.A. station; it then runs in the median of the San Bernardino Freeway to the El Monte Station along the former route of the Pacific Electric Railway's San Bernardino Line. Starting at El Monte, the line parallels the Union Pacific's Sunset Route (ex-Southern Pacific) for a few miles before turning northeast at Bassett onto a Southern Pacific branch. At (a former Southern Pacific/Pacific Electric-Santa Fe crossing), it switches to the Santa Fe; from Claremont to just west of San Bernardino it follows what was the Santa Fe's Pasadena Subdivision (and before that the Second District of the LA Division, the Santa Fe passenger main line). The San Bernardino Line is mostly single track with 6 passing sidings and short sections of double track near Covina, between Pomona and Montclair, and west of Fontana.
 Passage 3:Massey joined the Canadian Army at the outbreak of World War I, and served on the Western Front in the Royal Regiment of Canadian Artillery. Lieutenant Massey returned to Canada after being wounded at Zillebeke in Belgium during the Battle of Mont Sorrel in 1916 and was engaged as an army instructor for American officers at Yale University. In 1918, he was recalled to active service and joined the Canadian Siberian Expeditionary Force that went to Siberia during the Allied intervention in the Russian Civil War. On the orders of his commanding general, he organized a minstrel troop with himself as end man to bolster morale of allied troops on occupation duty in Vladivostok.

[EX Q]: Question: How many phleboviruses are transmitted by ticks? Passage 1:The virus was discovered in 2014 by Olga Kosoy, Amy Lambert and colleagues from the Centers for Disease Control and Prevention (CDC) in Fort Collins, Colorado, in a sample of blood from the case patient. Tests had previously ruled out a wide range of tick-borne diseases including anaplasmosis, babesiosis, ehrlichiosis, Q fever, Rocky Mountain spotted fever and tularemia. During tests for Heartland virus, a recently discovered Phlebovirus known to be transmitted by ticks, prominent plaques, or areas where the cells were affected by virus infection, were observed on one-cell-thick cultures of African green monkey kidney cells. The plaques did not resemble the effects of Heartland virus, and the researchers hypothesized that they were the work of another virus. Recently developed "next-generation" sequencing techniques were employed to find novel viral RNA sequences in cell culture supernatants, similar to viruses of the genus Thogotovirus, family Orthomyxoviridae. Lambert, who worked on the sequencing, explained that these "state-of-the-art" techniques could be used to identify pathogens that older technologies could not detect.
 Passage 2:The People's Party (PP) is a conservative centre-right party that took its current name in 1989, replacing the previous People's Alliance, a more conservative party founded in 1976 by seven former Franco's ministers. In its refoundation it incorporated the Liberal Party and the majority of the Christian democrats. In 2005 it integrated the Democratic and Social Center Party. It governed Spain under the prime ministership of José María Aznar from 1996 to 2004, and again from December 2011, and after much uncertainty caused by the inconclusive results of the 2015 general election and the 2016 election when the People's Party formed a minority government with confidence and supply support from conservative Ciudadanos (Cs) and the Canarian Coalition (CC), which passed due to the Spanish Socialist Workers' Party (PSOE) abstaining. A motion of no confidence in the Spanish government of Mariano Rajoy was held between 31 May and 1 June 2018, registered by the Spanish Socialist Workers' Party (PSOE) after the People's Party(PP) was found to have profited from the illegal kickbacks-for-contracts scheme of the Gürtel case. The motion was successful and resulted in the PSOE leader Pedro Sánchez becoming the new Prime Minister of Spain until his 2019 state budget was rejected requiring him to call a snap election for April 28 of the same year.
 Passage 3:In July 1994, two students of Taipei First Girls' High School committed suicide by charcoal-burning in a hotel in Su'ao, Yilan with a note that didn't state the reason clearly, even though that it was suspected in some mass media that they were a lesbian couple. In November 1998, a middle-aged woman in Hong Kong died by suicide using this method inside her small, sealed bedroom. She had a chemical engineering background. Hong Kong was suffering from an economic depression at the time, and suicide in general was increasing. After the details of this suicide were highly publicised by local mass media, many others killed themselves in this way (an example of the Werther effect). Within two months, charcoal-burning had become the third major suicide killer in Hong Kong. Charcoal-burning suicide accounted for 1.7% of Hong Kong suicides in 1998 and 10.1% in 1999. By 2001, it had surpassed hanging as the second most-common method of suicide in Hong Kong (second only to jumping), accounting for about 25% of all suicide deaths. The method has since spread to mainland China, Taiwan and Japan.

[EX Q]: Question: Did Richard Moody travel alone when he landed on Falkland Islands? Passage 1:The Falkland Islands have been claimed and occupied by several nations throughout its history, who generally used their national flags on the islands. It wasn't until 1876 that the islands were given a flag of their own, which consisted of a Blue Ensign defaced with the seal of the islands - an image of HMS Hebe (which brought many of the early British settlers to the islands, including Richard Moody, in the 1840s) in Falkland Sound, overlooked by a bullock (representing feral cattle which once roamed the islands). A new coat-of-arms for the islands was introduced on 16 October 1925, consisting of the Desire (which was captained by John Davis who is reputed to have discovered the islands in 1592) and a sea lion in a shield surrounded by the motto of the islands, Desire the Right. This coat-of-arms later replaced the image of the bullock and ship on the flag.
 Passage 2:He then transferred to India, traveling initially to Hamburg where, though both were in disguise and had no political principles in common, he was warned by Napper Tandy to flee to Danish territory in Altona. He continued overland through Germany, Austria, and Serbia, to the Euxine where he felt obliged to force his ship's captain at gunpoint to take him to Constantinople as agreed, rather than a corsair port for murder or slavery. He passed through Greece without recorded incidents, and took ship for Aleppo. He narrowly saved his own life, and his servant's, in the desert by curing the chief of a band of Arabs, who were planning to murder and rob him. He stayed for some time in Baghdad, where he was presented with a valuable Arabian horse by the Ottoman governor. From Basra he took ship for Bombay, then travelled overland to Madras. He was soon appointed to the command of the 19th Dragoons at Arcot, some 16 miles from Vellore.
 Passage 3:Hamilton followed his mother as a Christian Scientist, and attended Claremont Fan Court School and then Eton College. He did National Service in the Coldstream Guards from 1955 to 1958. His father had been wounded while serving with the same regiment in the Second World War. Hamilton then worked in the City of London as a gilts broker. He was a member of the London Stock Exchange from 1967 to 1980. He remained in the City for only a short period, leaving when he inherited two estates from his father's cousin. He married his wife, Corinna Dixon, in 1967, and they had four sons together. He succeeded his father as Baron Hamilton of Dalzell in 1990, inheriting land near and properties in the village of Betchworth in Surrey, and a Regency mansion.
