Practical examples
Introduce the location
- Before

The revision lets an unfamiliar reader identify the location without recognizing a regional abbreviation.
Name a destination
- Before

The illustrative address becomes more specific; check the real office address before using it.
Identify the actor

The sentence now identifies an institution as the actor; the policy statement itself still needs verification.
