Below is how each will look. Let me know if you have any questions.

@dorothyyeager @kathycarothers @djgarr Can you take a look at the draft language and let me know if you have any edits?

One suggested edit - "across the spectrum" isn't really needed; would recommend just taking it out.

Looks good and I agree with Dorothy's comment.
