In what way did high wages and worker safety regulations affect the war effort? a: they encouraged immigrants to become citizens so they could get jobs and join the war effort. b: they encouraged workers to apply for exemptions to the draft, reducing the size of the army. c: they forced industries to invest in their workforce at home rather than in the war effort overseas. d: they guard against the possibility of strikes that would slow wartime production.

The correct answer is D: They helped guard against the possibility of strikes that would slow wartime production.

In times of war, wartime production was essential for the continuity and success of projects overseas. This was regarding clothing, food, weapons, vehicles, etc. Everything was cheaper, safer and more patriotic if it was manufactured home. It was because of this reason that it was so important to keep wartime production fast and efficient.

To do this, employers and factory owners had to make sure that their factory workers wouldn't go on strikes. Raising wages and better worker safety regulations helped to maintain a good spirit between the workers, preventing revolts, strikes and boicots.

early human migrations are the earliest migrations and expansions of archaic and modern humans across continents and are believed to have begun approximately 2 million years ago with the out of africa migration of homo erectus. this initial migration was followed by other archaic humans including h. heidelbergensis, which lived around 500,000 years ago and was the likely ancestor of both denisovans and neanderthals. early hominids were said to have "crossed land bridges that were eventually covered in water" .

within africa, homo sapiens dispersed around the time of its speciation, roughly 300,000 years ago.the "recent african origin" paradigm suggests that the anatomically modern humans outside of africa descend from a population of homo sapiens migrating from east africa roughly 70,000 years ago and spreading along the southern coast of asia and to oceania before 50,000 years ago. modern humans spread across europe about 40,000 years ago.

the migrating modern human populations are known to have interbred with local varieties of archaic humans, so that contemporary human populations are descended in small part (below 10% contribution) from regional varieties of archaic humans.

after the last glacial maximum, north eurasian populations migrated to the americas about 20,000 years ago. northern eurasia was peopled after 12,000 years ago, in the beginning holocene. arctic canada and greenland were reached by the paleo-eskimo expansion around 4,000 years ago. finally, polynesia was peopled after 2,000 years ago, by the austronesian expansion.
