Which of the following is true of European-American migrants trekking West along the Oregon and California trails?

A) Death rates from disease were significantly higher than in society at large.
B) For most adults, trail life was not particularly dangerous.
C) They only killed bison or other animals for food.
D) They were constantly subjected to Indian attacks.

For most adults, the journey along the Oregon and California trails was not particularly dangerous. While there were risks, including disease and accidents, the overall death rate among migrants was not significantly higher than the general population of the time. The perception of constant danger from Native American attacks and the idea that all wildlife was killed solely for food are exaggerated. Many migrants hunted for sport or to protect livestock, and while conflicts with Native Americans did occur, they were not as constant as often portrayed.
