Hey there!
Let's start out with one thing at a time.
The word <em>modifier </em> means when a adjective or even a noun make's it impossible to add a sense or even a head of subject.
So, in the sentence above, this would be known as a (misplaced) and not a dangling modifier because it is clear that the sentence used the phrase
"three fire flying" which in this case would be known as a modifier.
Your correct answer would be
. . . .
Hope this helps.

A) To make each stanza in the poem slightly longer.
I don't completely understand the point of this, but it has something to do with the way the poem sounds and is read. The rhyme scheme of a poem can impact the audience's feelings towards that poem, and that's what I assume the poet was going for.
