Question

What evidence would most weaken the counterclaim

Answer 1

Answer:

The physiologies of humans and some animals are very similar, so the reactions of these creatures to certain medications are the most reliable guide to the possible reactions of human patients.

Scientists are more easily able to control an animal's environment, such as diet and temperature, than they are that of humans, which makes the tests far more reliable than alternative methods.

Explanation:

According to a different source, these are the claim and the counterclaim that come with this question:

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.

Counterclaim: There are safer and more accurate ways to test medications without using animals.

This is the evidence that would most weaken the counterclaim. In this example, the counterclaim states that there are other safer and more accurate ways of testing medications besides the use of animals. However, this evidence shows that these tests are the most accurate because of the similar physiologies of some animals and some humans. It also shows that these tests are safer because it is easier to control an animal's environment than that of a human.
