Wondering if we can provide a more specific example for clarity

Suggested change

	When you are using a screen reader,
	you will know the common purpose of the select option (eg., date, time, state).
	When you are using a screen reader,
	you will hear the common purpose of the select option (eg., "Select your state").

I like that revision especially since select elements are often used for a variety of common lists. I think state, day, time are all good options.

Updated to "eg., "Select your state"" in ef4aa40

Committed a change to add a missing period. Have a question for a11y team about whether we're referencing the correct WCAG criterion on the test "Content doesn’t change until the user takes an action to change it."

I believe I have addressed all your comments. This is ready for your re-review.

[mahoneycm]

A couple small changes for consistency with recent test pages.

Potentially non-blocker as these are changing over time. We discussed doing an audit in the future to catch inconsistencies but it'd be nice to get ahead of it

I think everything has been resolved that I was asked to look at, so I give the all clear!
