Which statement about the journey across the American continent in a covered wagon in the early 1800s is accurate?

A covered-wagon journey across the continent was hazardous, and travelers could face disease as well as shortages of clean water. The trip usually took several months, often around four to six months, so it generally lasted longer than the month or two described in choice C. Therefore, the accurate statement is that the trip included the threat of disease and lack of water.
