What is a couplet, in the context of a shakespearean sonnet?

In the context of a Shakespearean sonnet, a couplet represents the final two lines (A).

Explanation:

In poetry, a couplet is a pair of lines that typically rhyme and have the same length. Sometimes, poets write the whole poem in couplet form. However, Shakespeare often used rhyming couplets at the end of his sonnets, to make the ending more effective. One such example is a couplet from his Sonnet 81:

"You still shall live, such virtue hath my pen,

Where breath most breathes, even in the mouths of men."

faulty parallelism is a construction in which two or more parts of a sentence are equivalent in meaning but not grammatically similar in form.

the correct version of this faulty parallelism in the sentence is:

the hikers knew that the hike was six miles, that it usually required the entire day, and it would not be wise to start after 10: 00 a.m.

the problem is the last sentence, the first two have a basic subject+verb+object structure.

so, to give a proper balance to the structure, or better said, to give a parallel structure, we must write a basic s+v+o structure in all three sentences:

the hikers knew that the hike was six miles, that it usually required the entire day, and it would not be wise to start after 10: 00 a.m.

the whisper is the answer, hope this : )
