Which lines from the poem provide the best support for the answer to part a sonnet 5

There aren't any lines nor answers in this question.

Explanation:

However, it is possible to explain some things.

A sonnet is a poem of fourteen lines; it uses iambic pentameter, meaning that each line has 10 syllables. It has a specific rhyme scheme and a specific turn called volta. They are usually divided into different groups according to the rhyme pattern. There are different types of sonnet, such as Italian (or Petrarchan,) Shakespearian, Spenserian, and Miltonic, among  others. This is an example of an Italian sonnet by Elizabeth Barrett Browning, entitled "How I Love Thee"

How do I love thee? Let me count the ways.

I love thee to the depth and breadth and height

My soul can reach, when feeling out of sight

For the ends of being and ideal grace.

I love thee to the level of every day’s

Most quiet need, by sun and candle-light.

I love thee freely, as men strive for right;

I love thee purely, as they turn from praise.

I love thee with the passion put to use

In my old griefs, and with my childhood’s faith.

I love thee with a love I seemed to lose

With my lost saints. I love thee with the breath,

Smiles, tears, of all my life; and, if God choose,

I shall but love thee better after death.
