Question

university of pennsylvania neurocriminologist adrian raine has studied the link between nutrition and aggressive behavior. research shows that aggression has a neurobiological basis, and omega - 3 fatty acids play a critical role in brain function by enhancing neuron growth and regulating neurotransmitters. in a 2024 meta - analysis, raine and colleague lia brodrick examined 29 randomized controlled trials with nearly 4,000 participants and found that omega - 3 supplementation produced a 30% reduction in aggression. the effects were consistent across participants age, gender, clinical diagnosis, treatment duration, and dosage. raine concludes that ______
which choice most logically completes the text?
a larger doses of omega - 3 supplements produce greater reductions in aggression
b omega - 3 supplementation may be useful for reducing aggression in a variety of populations and settings
c omega - 3 supplementation can eliminate aggressive behavior entirely
d omega - 3 supplementation reduces aggression only in participants with clinical diagnoses

Explanation:

The text states that the effects of omega - 3 supplementation on reducing aggression were consistent across participants' age, gender, clinical diagnosis, treatment duration, and dosage. Option A: The text doesn't compare different doses to show that larger doses give greater reduction, so A is wrong. Option B: Since the effects were consistent across various factors (age, gender, diagnosis, etc.), it implies that omega - 3 supplementation could be useful in different populations and settings, which matches. Option C: The text says there was a 30% reduction, not elimination, so C is wrong. Option D: The effects were consistent across clinical diagnosis, meaning it's not only for those with clinical diagnoses, so D is wrong.

Answer:

B. omega - 3 supplementation may be useful for reducing aggression in a variety of populations and settings
