Mice given anti-oxidants with their food can live 30% longer than mice given a normal diet. Such results

B) are difficult to interpret because the long lived mice also eat less
C) provide good evidence for garbage accumulation theories of senescence
D) argue against garbage accumulation theories of senescence

Question

Quizplus · Accepted Answer

The fact that the long lived mice also eat less makes it difficult to interpret whether the increased lifespan is due to the anti-oxidants or the reduced caloric intake. Therefore, option B is the best choice. Option A is incorrect because the study only shows that anti-oxidants can increase lifespan, but it does not necessarily support free radical theory. Option C is incorrect because the study does not provide evidence for garbage accumulation theories. Option D is also incorrect because the study does not argue against garbage accumulation theories.
