PROBLEM: Question: How old was the governor when Rosas was overthrown? Passage:The central figure in the overthrow of Rosas, Entre Ríos Governor Justo José de Urquiza, was granted the power of a head of state by the Palermo Protocols of April 6, 1852. This provoked resistance in Buenos Aires, however, which then refused to ratify the San Nicolás Agreement of May 31. The prospect of having the Argentine Congress headquartered in Santa Fe proved especially objectionable, and Urquiza's June 12 appointment of former President Vicente López y Planes failed to turn public opinion in Buenos Aires. Colonel Bartolomé Mitre rallied the Assembly against the San Nicolás Accords. The most contentious issue remained the Buenos Aires Customs, which remained under the control of the city government and was the chief source of public revenue. Nations with which the Confederation maintained foreign relations, moreover, kept all embassies in Buenos Aires (rather than in the capital, Paraná).

PROBLEM: Question: How many years did the Great Depression last? Passage:Originally from New Brunswick, Harrison graduated from Nova Scotia Agricultural College in 1922, and, in 1924, from the Ontario Agricultural College with a B.Sc. in agriculture. He earned an MSc in plant pathology from Macdonald Campus of McGill University a year later. A doctoral degree he started at the University of Toronto in 1929 was abandoned due to the Great Depression. He established a herbarium of mycological specimens where he was employed for many years at the Kentville Research Station (now the Atlantic Food and Horticulture Research Centre); most of his collections are now housed at the Canadian National Mycological Herbarium. His early research concerned the fungal infestation of plants, such as that of Colletotrichum lindemuthianum on beans (Phaseolus). Working with John Frederick DeWitt Hockey, they made many contributions to the control and prevention of diseases of horticultural crops. They were among the first to use the sticky slide spore trap to estimate the densities of fungal spores.

PROBLEM: Question: How long is the river where tension between the Syrian Army and Syrian Democratic Forces was high near Deir ez-Zor? Passage:Tensions between the Syrian Army and the Syrian Democratic Forces in the eastern bank of the Euphrates of Deir ez-Zor Governorate have always been high following the liberation of Deir ez-Zor city from ISIL and the SDF's capture of large parts of the area following its offensive against ISIL with CJTF–OIR support. On 16 September 2017, either Syrian or Russian aircraft bombed SDF positions on the eastern bank. On 25 September, Russian and Syrian forces shelled SDF forces in the nearby Conoco gas field. Between 7 February and 8 February 2018, clashes between the SDF and pro-Syrian government forces near Khasham resulted in US airstrikes on pro-government forces which killed dozens of pro-government militiamen, allegedly including contractors of the Russian private military company Wagner Group. Additional armed incidents took place in the following weeks.
