Read the poem. The Courage That My Mother Had

by Edna St. Vincent Millay.

The courage that my mother had

Went with her, and is with her still:

Rock from New England quarried;

Now granite in a granite hill.

The golden brooch my mother wore

She left behind for me to wear;

I have no thing I treasure more:

Yet, it is something I could spare.

Oh, if instead she’d left to me

The thing she took into the grave!—

That courage like a rock, which she

Has no more need of, and I have.

In "The Courage That My Mother Had," what does the phrase That courage like a rock tell readers about the speaker's mother?

She protects the speaker from harm.

Her bravery and strength is unwavering.

She is strict and inflexible.

Her personality is difficult to relate to.
