What did the Animal Welfare Act govern when it was passed in 1966?

• A. The sale of animals as pets
• B. The use of animals in research, testing, and teaching
• C. The regulation of animal farms
• D. The care of zoo animals

Answer: (B)

The key idea here is how the law defined its reach in 1966. The Animal Welfare Act was enacted to ensure humane treatment of animals used in biomedical contexts, which means it set standards for the care, housing, handling, and transport of animals in research facilities and other settings. It also created licensing and inspection requirements for entities that deal with or exhibit animals. This focus on how animals are used in research, testing, and teaching is why this option is the best fit. While the act does touch on aspects like dealing with certain animals and exhibitors, its primary purpose at the time was to govern the use and welfare of animals in research, testing, and teaching, not general pet sales, farming, or zoo care.
