I have a question about a prepositional phrase.
-Don't throw the cigarette butts away in the trash bin.
-Make sure to throw away all the paper on the floor.
Both of two sentences have the same verb and the same prepositional phrase.
However, the latter prepositional phrase is an adjectival one - paper which is on the floor, while the former one is an adverbial one - put them in the trash bin, not in the other places. Right?
What made this difference? I wonder if there is any possibility that the second sentence could be understood by the meaning of "Be sure to discard all the paper on the floor(not on any other places)"?
Thanks in advance.
