Question

What does a journal written by frontier settlers most likely tell you about Manifest Destiny?

what conditions were like during travels



what settlers thought about “Manifest Destiny”



when Manifest Destiny occurred



where Manifest Destiny took place



where American Indians fought for their lands

Answer 1

Depending of course slightly on the journal in question, the best option would be "what conditions were like during travels," since these accounts would be far more personal in nature than other writings on the idea of Manifest Destiny itself.
