Question

Read "Sonnet 292” by Petrarch.

Answer 1

The correct answer is A) realizes the full impact the loss of the woman has on his life.
An octave consists of eight lines - in this example, it ends with Are now a little dust, all feeling gone; and the sestet (containing six lines) begins with And yet I live, grief and disdain to me. 
As you can see, the shift in ideas is quite obvious here - in the octave, the poem celebrated the woman's beauty, but in the sestet, we can see that she is gone and that he cannot get over that loss.

Answer 2

I think it is A) realizes the full impact the loss of the woman has on his life since it mostly talking in past tense. I hope this helps
