Why is the trip by raft so difficult for the Spaniards?

They did not know how to navigate.

Explanation:

In the context of 'A Desperate Trek Across America,' the Spaniards went on a trip to explore the American culture.

This leads them to struggle for even their survival for which they have to further shift to new resources in order to survive. Thus, option B is the correct answer.

each year on this day, i make it a point to listen to dr. martin luther king jr.’s great “i have a dream” speech. it’s electrifying every single time.
