Which framework was established most recently?

Which framework was established most recently?

• A. 5 domains
• B. 3 Rs
• C. 5 freedoms
• D. 3 orientations

Answer: (A)

This item is about which animal-welfare framework was introduced most recently. The three Rs—replacement, reduction, and refinement—originated in 1959 and shaped how research uses animals. The five freedoms were published in 1965 to describe fundamental welfare conditions like freedom from hunger, discomfort, pain, fear, and the ability to express normal behavior. A newer framework, the five domains, was developed later to provide a more comprehensive assessment by separating welfare into four physical/functional areas—nutrition, environment, health, and behavior—and a fifth domain that captures the animal’s mental state. This integration of physical factors with affective experience makes it the most recent of the frameworks. Thus, the five domains is the correct choice.
