Which term refers to a zone in Europe where passport checks are not required for travel among many countries?

• A. Single Market
• B. Sovereignty
• C. Stakeholder
• D. Schengen Area

Answer: (D)

Passport-free travel within a defined European zone is what this item is about. The term describes an area where border checks between member countries are largely abolished, letting people move across internal borders without routine passport controls. The Schengen Area embodies this idea: most European Union countries participate, along with a few non-EU states, and you can usually travel from one member country to another without showing a passport at each border. External borders still have controls, and several European countries are not part of Schengen and maintain border checks. This contrasts with the other terms, which describe broader or different concepts: the single market covers free movement of goods, services, people, and capital but isn’t defined by passport-free travel; sovereignty refers to a state's supreme authority; a stakeholder is any party with an interest in a decision.
