Explanation:
Do you have personal experience I can use for this
In a history book it can be in the review too :)
The sentence that contains a misplaced or dangling modifier is the one that follows:
B. Being from a small town in Wisconsin, the subway was a new experience for Matt.
All the information which appears before the comma (being from a small town in Wisconsin) seems to be related to the subway, and not to Matt, since "the subway" appears right after it. Obviously, the purpose was to use a modifier (the whole clause, in this particular case) in order to give information about Matt, and not about the subway. A better way to convey the idea originally intended would be:
Being from a small town in Wisconsin, Matt experienced the subway as something new.
In Why, You Reckon the narrator and the other man don't hold Edward for ransom because they just were interested in the money he had.
I would say the motivation for not doing so was external since they were hungry and taking the time for holding Edward would have taken a lot of time.
