Answer: 1. Three quatrains and one couplet.
3. abba, cddc, effe, gg rhyme scheme.
Explanation: Shakespearean sonnets typically consist of 14 lines with the abab cdcd efef gg rhyme scheme. This means that the first and third lines must rhyme, and the second and fourth lines must rhyme. In the next set of four lines, the same pattern is repeated with different rhymes. The poem ends with a rhyming couplet. And they often explore a theme or idea with a volta (shift in tone or argument) occurring between the third quatrain and the final couplet. The poem consists of three quatrains, which are four-line stanzas. Each quatrain explores a different aspect or idea.
