Besides, as a preposition, means except and in addition to. What does the sentence Besides Jack, no one voted for her. mean?
A: Except Jack, no no one voted for her = Only Jack voted for her!
B: Jack did not vote for her, and no one else voted for her either.
I think the answer is A. Can we say when "besides" comes with negative structures, it must be understood as "except"? Or, Is the sample sentence ambiguous and can mean both?
