Problem: By 1921, the Bolsheviks were winning the Russian Civil War and foreign troops were beginning to withdraw, yet Bolshevik leaders continued to keep tight control of the economy through the policy of War Communism. After years of economic crises caused by World War I and the Russian Civil War, the Bolshevik economy started to collapse. Industrial output had fallen dramatically. It is estimated that the total output of mines and factories in 1921 was 20 percent of the pre-World War I level, with many crucial items suffering an even more drastic decline. Production of cotton, for example, had fallen to 5 percent and iron to 2 percent of the pre-war level, and this coincided with droughts in 1920 and 1921 and the Russian famine of 1921. Discontent grew among the Russian populace, particularly the peasantry, who felt disadvantaged by Communist grain requisitioning . They resisted by refusing to till their land. In February 1921, more than 100 peasant uprisings took place. The workers in Petrograd were also involved in a series of strikes, caused by the reduction of bread rations by one third over a ten-day period.

Problem: Early in 1277, before the main royal army had been mustered, Edward deployed, in south and mid-Wales, a mixture of forces comprising paid troops, some of the marcher lords' retainers and knights of the royal household. They met with considerable success as many of the native Welsh rulers, resentful of Llywelyn's overlordship, surrendered and joined the English. In July 1277, Edward launched a punitive expedition into North Wales with his own army of 15,500 — of whom 9,000 were Welshmen from the south — raised through a traditional feudal summons. From Chester the army marched into Gwynedd, camping first at Flint and then Rhuddlan and Deganwy, most likely causing significant damage to the areas it advanced through. A fleet from the Cinque ports provided naval support. Llywelyn soon realised his position was hopeless and quickly surrendered. The campaign never came to a major battle. However, Edward decided to negotiate a settlement rather than attempt total conquest. It may be that he was running short of men and supplies by November 1277 and, in any case, complete conquest of Llywelyn's territories had not been his objective.

A: 6500

Problem: On 24 August, Charles X Gustav joined Wittenberg's forces. The Polish king John II Casimir left Warsaw the same month to confront the Swedish army in the west, but after some skirmishes with the Swedish vanguard retreated southwards to Kraków. On 8 September Charles X Gustav occupied Warsaw, then turned south to confront the retreating Polish king. The kings met at the Battle of Żarnów on 16 September, which like the next encounter at the Battle of Wojnicz on 3 October was decided for Sweden. John II Casimir was exiled to Silesia while Kraków surrendered to Charles X Gustav on 19 October. On 20 October, a second treaty was ratified at Kėdainiai in the north. The Union of Kėdainiai unified Lithuania with Sweden, with Radziwiłł recognizing Charles X Gustav as Grand Duke of Lithuania. Over the following days, most of the Polish army surrendered to Sweden: on 26 October Koniecpolski surrendered with 5,385 men near Kraków, on 28 October Field Crown Hetman Stanisław Lanckoroński and Great Crown Hetman Stanisław "Rewera" Potocki surrendered with 10,000 men, and on 31 October the levy of Mazovia surrendered after the Battle of Nowy Dwór.
