Step-by-step explanation:
The subject of this question is Social Studies.
In this scenario, the concern over Valerie's age and appearance relates to the concept of legal drinking age and age restrictions in establishments.
The establishment is likely a bar or club where the legal drinking age is 18 or 21, depending on the location. Scrutinizing her identification and double-checking if she is a minor is important to ensure compliance with legal requirements.
By addressing the importance of scrutinizing her identification, the establishment can avoid potential legal issues and maintain a safe environment for both Valerie and other patrons.
