Problem: Modern history:

The Russian Civil War was a multi-party war that occurred within the former Russian Empire after the Russian provisional government collapsed and the Soviets under the domination of the Bolshevik party assumed power, first in Petrograd (St. Petersburg) and then in other places. In the wake of the October Revolution, the old Russian Imperial Army had been demobilized; the volunteer-based Red Guard was the Bolsheviks' main military force, augmented by an armed military component of the Cheka, the Bolshevik state security apparatus. There was an instituted mandatory conscription of the rural peasantry into the Red Army. Opposition of rural Russians to Red Army conscription units was overcome by taking hostages and shooting them when necessary in order to force compliance. Former Tsarist officers were utilized as "military specialists" (voenspetsy), taking their families hostage in order to ensure loyalty. At the start of the war, three-fourths of the Red Army officer corps was composed of former Tsarist officers. By its end, 83% of all Red Army divisional and corps commanders were ex-Tsarist soldiers.

Where did Soviets under the rule of the  Bolshevik first assume power during the Russian Civil War?

A: Petrograd (St. Petersburg)


Problem: In Serbia, the Serbian language is the official one, while both Serbian and Croatian are official in the province of Vojvodina. A large Bosniak minority is present in the southwest region of Sandžak, but the "official recognition" of Bosnian language is moot. Bosnian is an optional course in 1st and 2nd grade of the elementary school, while it is also in official use in the municipality of Novi Pazar. However, its nomenclature is controversial, as there is incentive that it is referred to as "Bosniak" (bošnjački) rather than "Bosnian" (bosanski) (see Bosnian language for details).

After an initial loss to Labor at the 1946 election, Menzies led the Liberals to victory at the 1949 election, and the party stayed in office for a record 23 years—still the longest unbroken run in government at the federal level. Australia experienced prolonged economic growth during the post-war boom period of the Menzies Government (1949–1966) and Menzies fulfilled his promises at the 1949 election to end rationing of butter, tea and petrol and provided a five-shilling endowment for first-born children, as well as for others. While himself an unashamed anglophile, Menzies' government concluded a number of major defence and trade treaties that set Australia on its post-war trajectory out of Britain's orbit; opened Australia to multi-ethnic immigration; and instigated important legal reforms regarding Aboriginal Australians.
During what period did Australia experience long-term economic growth?
A: the post-war boom period of the Menzies Government (1949–1966)
