The correct answer is B. it does not follow a formal structure.
Let us first go through all of these options in order to determine the structural characteristics of <em>Forgetfulness, </em>by Billy Collins.
Option A is incorrect - if you count the syllables in each line, you will see that the first one has 11, the second one 13, and so on - so, not 10.
Option C is also incorrect - there are actually 8 stanzas, and they are not of equal length.
Option D is also incorrect - there are no rhymes in this poem.
So, by the process of elimination, the correct answer is B - this poem doesn't follow a formal structure - it is rather a free verse poem containing stanzas of varying lengths.
I'm pretty sure the answer is the third one!
I'm gonna say that the answer is C. They valued perseverance, bravery, and strength. and D. They believed the gods were active in peoples lives.
I hope this helps!
