Your translation seems to hit on certain points but miss others.
Leaving aside factual matters (like character names and US geography), here are some misunderstandings that seem to be interfering with your interpretation:

Force a person smoothly painting the fence as a punishment.
まんまと is not modifying the painting of the fence but the verb 押しつける.
Maybe ask yourself these questions:
- Whose "punishment" is it?
- Who is the 人 who ends up painting the fence?
It's perhaps more complicated if you aren't familiar with the story of Tom Sawyer, but you should still be able to figure it out from context.
Think about that and then try to answer questions 50 and 51.
Related to that: if your implied translation of 51 ("Afterall, there is nothing as boring as this world.") were correct, would that be a positive message (エール) to the readers?

Understand the unreturned, the management party of the mansion of ex-Washington's residence supplied approximately 1 million yen the same edition of the old book.
This sentence doesn't make much sense in English, so it's hard to tell if you understand the original JP.
One hint: 調達 doesn't mean "supply".
Another hint: the estate of George Washington had to give back the overdue book to the library. What did they do after that?
Perhaps try giving your answers for all the questions.
That will make it easier for us to tell what you do understand, and help you with what you don't.
