The most widely accepted theory on how early humans migrated to North America is the one that raises that the first settlers of North America crossed from Siberia through the Bering Strait.
For 19,000 years there was the possibility that the primitive tribes of Asia could cross the Beringia bridge. The first one to compose a possible migratory model of Asians to America through Beringia was Caleb Vance Haynes in an article published in the journal Science in 1964.
The most important data to establish a migratory theory during the last glaciation is the fact that Canada was completely covered with ice during the last glaciation, invaded by two gigantic plates: the laurentine ice plate and the ice plate of the mountain range. This made it impossible to enter the continent beyond Beringia.
A theory was then developed: shortly before the end of the last glaciation and the Beringia bridge was flooded, the edges in contact of the two large ice sheets covering Canada began to melt, opening an ice-free corridor of about 25 km wide, which followed, first the valley of the Yukon River and then the eastern edge of the Rocky Mountains along the Mackenzie River corridor. Scientists who hold the theory estimate that this occurred in 14,000 BC, although others question the date and claim that it could not have happened until 11,000 BC. At that time the human beings who were in Beringia could move towards the interior of America although there is still no physical evidence to prove the fact itself.
This theory was articulated with the discoveries of the Clovis culture that dated from the year 13,500 BC to conclude that it had been integrated by the first migrants that entered by the bridge of Beringia, which in turn would have descended all the other cultures indoamericanas.

Answer:
German submarine attacks on American ships
Explanation:
When the WWI began, the U.S. decided to maintain its isolationist policy, however, the continuous use of submarine warfare by Germany in the North Atlantic and the Mediterranean that put American ships and citizens at risk and caused the sinking of several ships caused tension to increase between both nations and brought the U.S. closer into the war.
On January 31, 1917, when Germany formally announced its unrestricted submarine warfare policy, the U.S. finally determined to end diplomatic relations with Germany and entered into World War I on the side of the Allies in April.

You have not included "the following," but it is possible to answer this question by saying that Europeans relied primarily on Africans rather than on American indigenous peoples for labor because the former were significantly more resilient and immune to the microbes conveyed by the Europeans than the latter. It must be added, nevertheless, that the American Indians were also slaved in large numbers and sent to work in areas like the West Indies or Mexico.
