Read the sample student claim and the reasons listed for making this claim. Claim: Although many people argue that medical testing on animals is a violation of animal rights, the benefits it yields for society far outweigh any argument that can be made.

Reason #1: Animal research has yielded both pain-relieving and life-saving drugs for humans.

Reason #2: Laws prohibit scientists from using animal-based research in cases where non-animal testing would produce equally clear and valid results.

Which piece of evidence would best support reason #2?

*Animal research is extremely costly, so it is in the best financial interest of scientists to pursue other means of testing before deciding to utilize animals in their research.
*With just 115 inspectors and over 7,500 facilities involved with the research, breeding, or handling of animals in some way, regulation of the Animal Welfare Act is virtually impossible.
*Enacted in 1966, the Animal Welfare Act is a US federal law that regulates the care and use of animals in a variety of circumstances, including medical research and testing.
*People will not tolerate the suffering of animals, so it is only logical that scientists will only use animal testing as a last resort when all other measures have failed.
