Paleo-Indians, Paleoindians or Paleoamericans is a classification term given to the first peoples who entered, and subsequently inhabited, the Americas during the final glacial episodes of the late Pleistocene period. The prefix "paleo-" comes from the Greek adjective palaios (παλαιός), meaning "old" or "ancient". The term "Paleo-Indians" applies specifically to the lithic period in the Western Hemisphere and is distinct from the term "Paleolithic".[1]
Evidence suggests big-animal hunters crossed the Bering Strait from Eurasia into North America over a land and ice bridge (Beringia), that existed between 45,000-12,000 BCE (47,000-14,000 BP).[2] Small isolated groups of hunter-gatherers migrated alongside herds of large herbivores far into Alaska. From 16,500-13,500 BCE (18,500-15,500 BP), ice-free corridors developed along the Pacific coast and valleys of North America.[3] This allowed animals, followed by humans, to migrate south into the interior. The people went on foot or used primitive boats along the coastline. The precise dates and routes of the peopling of the New World are subject to ongoing debate.[4]
Stone tools, particularly projectile points and scrapers, are the primary evidence of the earliest human activity in the Americas. Crafted lithic flaked tools are used by archaeologists and anthropologists to classify cultural periods.[5] Scientific evidence links Indigenous Americans to Asian peoples, specifically eastern Siberian populations. Indigenous peoples of the Americas have been linked to Siberian populations by linguistic factors, the distribution of blood types, and in genetic composition as reflected by molecular data, such as DNA.[6] There is evidence for at least two separate migrations.[7] Between 8000-7000 BCE (10,000-9,000 years BP) the climate stabilized, leading to a rise in population and lithic technology advances, resulting in more sedentary lifestyle.
The correct answer is A. The October Revolution in Russia.
Explanation
The First World War was a warlike confrontation that occurred in Europe between the years 1914 - 1918, in which most of the European power countries were involved, aligned on two sides, on the one hand, there was the Triple Alliance formed by the Central Powers: the German Empire, Ottoman Empire, Bulgaria, and Austria-Hungary. And on the other side was the Triple Entente, made up of the United Kingdom, France, Italy, the Japanese Empire, the United States, and the Russian Empire. On the other hand, the internal situation of Russia had been deteriorated by internal factors such as the weakness of the Russian army, the growing proletarian class that had aligned itself with socialist ideas, the loss of territory due to the war, the misery in some areas of the country, and the discontent of the population against the Tsar. Therefore, the revolution occurred at the hands of the soviets, a proletarian group that demanded that power be placed under their power to turn Russia into a Socialist State and get out of the war that had used a large part of the economic resources with those that the country counted and that had caused scarcity and poverty to many Russians. Finally, on November 7, 1917, the so-called "October Revolution" broke out, led by Leon Trotsky and Lenin, who formed the first Soviet government, the Council of People's Commissars, made up of characters called to play an important role in the future. like Trotsky, Stalin, and Rykov. Therefore, the correct answer is A. The October Revolution in Russia.

The abbasid dynasty tried to make an empire founded on the equal
opportunity of all Muslims. The new rulers stopped the large military subjugations,
finishing the supremacy of the Arab military class. Under the early
