Question

one argument against animal research is that most animal studies are a waste of time because the results may not even apply to humans. this claim is contradicted by which of the following facts about animal research?

• relatively few studies require subjecting the animals to painful or harmful manipulations.
• only 7–8% of all psychological studies involve animals.
• strict regulations have been imposed that control nearly every detail of how laboratory animals must be treated.
• animal studies have led to advances in the treatment of mental disorders, neuromuscular disorders, as well as many other disorders.

Explanation:

The original argument claims animal research is a waste because results don't apply to humans. To contradict this, we need a fact showing animal research does benefit humans. The first three options address animal treatment or prevalence, not applicability to humans. The last option demonstrates direct, applicable benefits to human health via medical advances.

Answer:

Animal studies have led to advances in the treatment of mental disorders, neuromuscular disorders, as well as many other disorders.
