Answer:
The first people migrated to America at the end of the last ice age because sea levels decreased from the massive glaciers providing a temporary bridge (Bering Land Bridge) connecting the old world and the new world. Scientists and Anthropologists predict this event occurred after 12,600 BP approximately 20,000 years ago
Explanation:
Over time this answer could change as newer technology and innovations are seen yearly.
I think its A. I'm not entirely sure but it does seem most logical.
<u>Anyways a big reason that these powers are limited is to keep society in a stable place. Tyranny brought onto any civilization over the years has led to its downfall. This balance helps keep both the government and its people under equal terms. </u>
Its not B. because this would allow tyrant rulers to keep their position putting everyone else at a disadvantage to please themselves. This simply doesn't make sense if you were to limit the government.
C. isn't a possibility either because each government only governs over said region.
D. can also be justified under my response to B. since it has the same meaning yet is worded differently/ or relates to more modern leaders I suppose.
Anyways, I hope I was helpful and good luck :D
Answer: B. US troops would gradually withdraw from Vietnam.
Context/detail:
Richard Nixon came into office as President in January, 1969. By that time the war in Vietnam involved hundreds of thousands of American troops and over 30,000 American lives had already been lost in the war. The war had become increasingly unpopular with the American people. In November, 1969, President Nixon gave a speech which announced his Vietnamization policy, which emphasized that the United States must empower South Vietnamese forces to assume more combat duties.
By the time the US was shifting emphasis to this sort of policy, it was too late to stave off the victory of the North Vietnamese and Viet Cong forces. The US eventually withdrew its forces from Vietnam in 1973, and by 1975, Saigon (in South Vietnam) fell to the North Vietnamese communist forces.
