Answer: Prohibition period from the early 1920s.
Explanation:
Many examples throughout history have had both positive and negative effects on society. Prohibition is one of the better examples. If alcohol were banned in the United States today, for example, there would be a "boom" of the country's black market. Alcohol would be made illegally and distributed on the black market. A positive response would be a reduction in the rate of violence and crime, given that a certain percentage of crime is linked to alcohol.
The Prohibition Period, however, proved to be a failed experiment in American history. The black market has risen sharply, and certain criminal groups have profited greatly. That profit is at the expense of the state since it is not legal. The ban creates a grey economy which badly affects the regular economy of the state.
It changed by everything going cruel and alarmed.
Correct answer: Russia's withdrawal from the war (World War I).
Russia withdrew from The Great War (which we now call World War I) after the Bolshevik Revolution brought Vladimir Lenin and the communists to power. Revolutionary activity broke out in Russia in February, 1917 -- during the time of World War I. Germany and Russia were on opposite sides in that war, and the German authorities helped Lenin, in exile, return to Russia in order to foment further revolution there and hurt the Russian government's ability to wage war in Europe. The major revolution in Russia, known as the Bolshevik Revolution, occurred in the fall of 1917. In March 1918, the new Soviet Russia government under Lenin ended its participation in the war, signing the Treaty of Brest-Litovsk.
