Read this passage, noting the connotations of words. Scoliosis curves your spine into an S, a biological scarlet letter glaringly visible by X-
ray but also perceptible to the naked eye. The upper half of my spine had bowed to
the right as I hit puberty while the lower half curved left. Scoliosis was a threat
never knew to anticipate.
What purpose do these words serve in the passage: scarlet letter,
glaringly, and threat?

Their only purpose is to make the reader feel sorry for the writer.

They are meant to draw attention away from the facts about scoliosis.

Their purpose is to make scoliosis seem a lot worse than it is.

They suggest the painful feelings associated with having scoliosis.
