Dangling modifiers occur when it is unclear to which word a descriptive part of sentence applies. A classic example would be "She left the room fuming" -- is it "she" or the room that's fuming?
But how about this sentence:
I found her in the library, studying history.
Could the intended meaning -- it was her who was studying history -- be misinterpreted to mean that I found her while I was studying in the library? Likewise, could the sentence be parsed to lead to the absurd interpretation that the library was doing the studying?
