Nutritionist: Some diet advocates claim that avoiding all dietary fats is necessary for maintaining a healthy cardiovascular system. However, this claim is mistaken. Certain fats, such as omega-3 fatty acids found in flaxseeds and walnuts, actually lower the risk of arterial inflammation and promote heart health.
Which of the following most accurately describes the method of reasoning employed by the nutritionist?
- Aattacking the character and motivations of the diet advocates rather than addressing their claims
- Binferring that because dietary fats are sometimes beneficial, avoiding all dietary fats is always harmful to cardiovascular health
- rejecting a universal claim by providing a specific counterexample that demonstrates its falsityCevap
- Darguing that because arterial inflammation has several causes, dietary fat cannot be the primary factor
- Etreating a condition that is merely sufficient for cardiovascular health as though it were strictly necessary
Cevap
Rejecting a universal claim by providing a specific counterexample that demonstrates its falsity
The nutritionist's technique consists of disproving a universal rule ('avoiding all dietary fats is necessary') by presenting a concrete counterexample (omega-3 fatty acids) that contradicts the rule.
