5. It is effective support for the claim.
The claim states that animals would be extinct if not for zoos. The evidence gives an example of two species who would have been extinct if not for zoos providing the opportunity for them to breed.
6. Television is a bad influence on children.
The paragraph uses evidence from a survey to show that parents have been embarrassed by behaviors they believe their children have learned through watching television. This would indicate that television is a bad influence.
7. Facts from a documentary about mechanical and artificial hearts.
This evidence would be ineffective because the claim is about organ donors. Mechanical and artificial hearts do not require organ donors.
8. The claim is effective.
It clearly gives the position that the author supports uniforms. It also doesn't use any "I" statements. It also does not suggest the essay will inform rather than argue.
