What do the following lines reveal about the structure of the Italian (or 'Petrarchan') sonnet?

The Italian sonnet is often called the Petrarchan sonnet after Francesco Petrarch, the
poet who made it famous. Many of Petrarch's sonnets are about unrequited love, a
common topic for sonnets that follow this form.

In an Italian sonnet, the first eight lines (called an octave) present a problem or
situation. The last six lines (called a sestet) provide an answer or resolution to the
problem. The switch from problem to resolution is called the turn. The octave of a
typical Italian sonnet has the rhyme scheme abbaabba, and the sestet follows either
cdecde or cdcdcd.
