What is the main focus of the AWA amendments made in 1985?

The main focus of the AWA amendments made in 1985 was to enhance the protection of animals used in research. These amendments sought to improve the welfare of animals by introducing various measures, such as requiring researchers to consider alternatives to animal testing, improve housing conditions, and ensure proper veterinary care. The emphasis was on establishing standards that would help mitigate pain and distress for animals involved in research and testing.

This focus on enhancing protection reflects a growing awareness of animal welfare issues and a commitment to promoting humane treatment within the scientific community. The other choices, while related to animal welfare, do not capture the specific intent of the 1985 amendments. For instance, while reducing the number of animals used in research is a goal of animal welfare advocates, the amendments did not directly target this aim. Clarifying regulations and increasing funding for welfare organizations are also important, but they were not the primary focus of these particular amendments.
