Not sure but o captain my captain was written by walt whitman about abe Lincoln and since Lincoln is considered an important figure in us history because he wanted to abolish slavery and considered to have ended slavery maybe the poem is famous because it was written about such an important historical figure. may not be the right answer but it is just my guess
Answer: Them is an indirect object
It is a noun, because you are talking about Mr. Mann.
The last sentence makes the most sense in this context because it is talking about dead and uncared for plants. The first and second sentences metion that the flowers are fresh,lush,well-watered, and nurtured, but the orginal sentence contradicts this.
