Why do you think it's important to Lewis to stretch the movement across continents?

The accomplishments of the Lewis and Clark Expedition were extensive. It altered the imperial struggle for the control of North America, particularity in the Pacific Northwest. It strengthened the U.S. claim to the areas now known as the states of Oregon and Washington.

Explanation:

the neutrality acts were passed by the united states congress in the 1930s, in response to the growing turmoil in europe and asia that eventually led to world war ii. they were spurred by the growth in isolationism and non-interventionism in the us following its costly involvement in world war i, and sought to ensure that the us would not become entangled again in foreign conflicts.

the legacy of the neutrality acts is widely regarded as having been generally negative: they made no distinction between aggressor and victim, treating both equally as "belligerents"; and they limited the us government's ability to aid britain and france against nazi germany. the acts were largely repealed in 1941, in the face of german submarine attacks on u.s. vessels and the japanese attack on pearl harbor.
