I'm not entirely sure but i think it was The Great Depression.
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 to this open question is the following.
As every single presidential term in the United States, Jimmy Carter had his ups and downs, positives and negatives.
Among the positive things, Carter opposed racial segregation, supported civil rights movements, established the Department of Education and the Department of Energy, supported legislation to conserve energy in the country, played a key role in the Camp David Accords to establish peace in the Middle East, and supported the signing of SALT II, as well as to give the operation of the Panama Canal to Panama´s government.
On the negative side, one of his first decisions that resulted controversially was to pardon the draft evaders of the Vietnam War. A decision that was questioned by many. He found it difficult to deal with stagflation, high unemployment rates, limited economic growth, he had to deal with the energy crisis at the end of his presidency, and also with the Iran hostage crisis. And one of the tensest moments, the Soviet Union invasion of Afghanistan.
87 years ago, the Founding Fathers created a brand new country here based on the idea that everyone is equal. Now, we are at war with ourselves, and this war is testing whether that kind of country can survive. A battle of this war was fought right here where we are standing. We are here today to dedicate a part of this battlefield as a cemetery for the soldiers that died here. This is the right thing to do. There is no way that we can ever bless this ground today more than the soldiers that died here already have. We can’t even come close. No one is going to care or remember the words we say here, but no one can ever forget what those soldiers did here. It’s up to the rest of us that are still alive to dedicate ourselves to finishing what these soldiers have started. It’s up to us to dedicate ourselves to saving the country, and remind ourselves that people have died for this cause. We have to promise that the soldiers here did not die for nothing. We have to promise that this country, under God, will be free again. We have to promise that a country that is made up of the people, was created by the people, and made to serve the people can exist in this world.
