What questions does the speaker of the sonnet pose and answer?

it contributes us a main part of idea and delivers it more meaning to the make it believeable --- The structure of a traditional Italian, or Petrarchan, Sonnet, is one of problem and resolution, often a question and answer. This concept was later adopted into English sonnet-writing and can be found in some of of the works of Shakespeare ("Shall I compare thee to a summer's day?") and Dickinson ("How do I love thee?") for instance. However, it is by no mean an absolute rule ("Quand vous serez bien vielle" by Ronsard, and "My mistress' eyes are nothing like the sun" - again Shakespeare's).
