Answer: B. The US government exempted the Amish, who do not believe in government assistance, from paying Social Security taxes.
Alexis de Tocqueville's concern for liberty had to do with personal liberties -- with freedom of conscience and belief being protected in a constitutional republic. By respecting the rights of the Amish to exempt themselves from the Social Security system, the government of the United States is allowing them to have liberty of their beliefs. They don't pay into the Social Security system, and also do not receive benefits from it. They choose to care for themselves and one another in the Amish community.
Alexis de Tocqueville's famous work was published in the 1830s. Based on his travels in the early United States, he wrote <em>Democracy in America, </em>in which he detailed how a democratic society functions.
Earliest human migrations and expansions of archaic and modern humans across continents began 2 million years ago with the migration out of Africa of Homo erectus. This was followed by the migrations of other pre-modern humans including H. heidelbergensis, the likely ancestor of both modern humans and Neanderthals. Finally, Homo sapiens ventured out of Africa around 100,000 years ago, spread across Asia around 60,000 years ago and arrived on new continents and islands since then.
Knowledge of early human migrations, a major topic of archeology, has been achieved by the study of human fossils, occasionally by stone-age artifacts and more recently has been assisted by archaeogenetics. Cultural and ethnic migrations are estimated by combining archaeogenetics and comparative linguistics.
