- The public board meeting begins at 7:00 p.m. in the county courthouse to discuss the change in regulations regarding the use of county equipment.

Examples of question tags:

- won’t we?
- can’t they?

Exclamation marks should be used sparingly in fiction, mostly in dialogue. They are not appropriate for non-fiction.
