How does Trollope address (or not address) her principal reasons for going to America in the book? Would her reasons for visiting in the first place influence her perception of Americans?

What are Trollope’s various reasons for writing the book, and how do they relate to or contrast with her reasons for going to America?

The book does not record Trollope’s impressions in real time (as in a diary) but rather as colored by hindsight, after she had made up her mind about America. Do you think it is possible to accurately reconstruct one’s travel experience after the fact? Why or why not?
