Problem: Given the question: Question: "In the early 20th century, what were used defined the time in a youth's life when they were allowed to start working" Context: "In Brazil, the minimum working age has been identified as fourteen due to continuous constitutional amendments that occurred in 1934, 1937, and 1946. Yet due to a change in the dictatorship by the military in the 80's, the minimum age restriction was reduced to the age of twelve but was reviewed due to reports of dangerous and hazardous working conditions in 1988. This led to the minimum age being raised once again to 14. Another set of restrictions was passed in 1998 that restricted the kinds of work youth could partake in, such as work that was considered hazardous like running construction equipment, or certain kinds of factory work. Although many steps were taken to reduce the risk and occurrence of child labour, there is still a high number of children and adolescents working under the age of fourteen in Brazil. It was not until recently in the 80's that it was discovered that almost nine million children in Brazil were working illegally and not partaking in traditional childhood activities that help to develop important life experiences."

Other nationalist and regional political groups also participated in the war, including the Ukrainian nationalist Green Army, the Ukrainian anarchist Black Army and Black Guards, and warlords such as Ungern von Sternberg. The most intense fighting took place from 1918 to 1920. Major military operations ended on 25 October 1922 when the Red Army occupied Vladivostok, previously held by the Provisional Priamur Government. The last enclave of the White Forces was the Ayano-Maysky District on the Pacific coast. The majority of the fighting ended in 1920 with the defeat of General Pyotr Wrangel in the Crimea, but a notable resistance in certain areas continued until 1923 (e.g., Kronstadt Uprising, Tambov Rebellion, Basmachi Revolt, and the final resistance of the White movement in the Far East)."
