USA HISTORY

Detailed explanation-1: -Stream and river crossings, steep descents and ascents, violent storms, and the persistent threat of disease among large groups of travelers were the most common challenges. Disease was the greatest threat on the trail, especially cholera, which struck wagon trains in years of heavy travel.

Detailed explanation-2: -Disease. Emigrants feared death from a variety of causes along the trail: lack of food or water; Indian attacks; accidents, or rattlesnake bites were a few. However, the number one killer, by a wide margin, was disease.

Detailed explanation-3: -The Oregon Trail was a roughly 2, 000-mile route from Independence, Missouri, to Oregon City, Oregon, that was used by hundreds of thousands of American pioneers in the mid-1800s to emigrate west. The trail was arduous and snaked through Missouri and present-day Kansas, Nebraska, Wyoming, Idaho and finally into Oregon.

Detailed explanation-4: -The game ends when the player reaches Oregon, or if they die along the trail; death can occur as a result of such things as disease, starvation, lack of clothing in cold weather, snakebites and hunting accidents.
