Answer 1

Most Americans were attracted to the Oregon Country by the rich soil of the Willamette River Valley, especially during the period of 'Oregon Fever' which contributed to the idea of Manifest Destiny. The correct answer is option: rich soil of the willamette river valley.

Step-by-step explanation:

Most Americans who migrated to the Oregon Country in the early 1840s were primarily attracted by the rich soil of the Willamette River Valley. During this period, known as "Oregon Fever," the United States was characterized by a widespread belief in Manifest Destiny, the idea that Americans were destined to expand across the continent. Oregon's fertile soil promised an opportunity for prosperous farming, attracting settlers to undertake the challenging journey along the Oregon Trail.

The migration was a part of the greater westward expansion of the United States, involving a variety of motivations, including economic opportunities and the possibility of a new start in life, rather than the pursuit of gold or the expectation of conflict with British troops.
