Task: Question Answering
Input (English): Passage: The revolt was led by the Left Socialist-Revolutionaries in Moscow. Previously, the Socialist Revolutionary Party had supported the continuation of the war by the Provisional Government after the February Revolution of 1917. The Bolshevik Party came to power in November 1917 through the simultaneous election in the soviets and an organized uprising supported by military mutiny. Several of the main reasons the population supported the Bolsheviks were to end the war and have a social revolution, exemplified by the slogan "Peace, Land, Bread". The Bolsheviks invited left SRs and Martov's Menshevik Internationalists to join the government. Left SRs split from the main SR party and joined the Bolshevik coalition government, supporting the Bolsheviks immediate enactment of the Socialist Revolutionary Party's land redistribution program. The Left SRs were given four Commissar positions and held high posts within the Cheka. The Left SRs still diverged with the Bolsheviks on the issue of the war and were dismayed that the Treaty of Brest-Litovsk gave up large amounts of territory. They left the Council of the People's Commissars in protest in March 1918. The Left SRs agreed with extrajudicial execution of political opponents to stop the counterrevolution but opposed having the government legally pronouncing death sentences, an unusual position that is best understood within the context of the group's terrorist past. The Left SRs strongly opposed the Treaty of Brest-Litovsk and opposed Trotsky's insistence that nobody was allowed to attack German troops in Ukraine. At the 5th All-Russia Congress of Soviets of July 4, 1918, the Left Socialist-Revolutionaries had 352 delegates compared to 745 Bolsheviks out of 1132 total. The Left SRs raised disagreements on the suppression of rival parties, the death penalty, and mainly, the Treaty of Brest-Litovsk.
