Question

students from high-income backgrounds have a higher volume of grey matter than students from low-income backgrounds. this boosts their:

physical health

memory capabilities

academic performance

Explanation:

Grey matter in the brain is closely linked to cognitive functions like memory, and research has established that greater grey matter volume in relevant brain regions supports enhanced memory capabilities. Physical health is not directly tied to grey matter volume differences here, while academic performance is a potential downstream outcome rather than the direct boost from grey matter itself.

Answer:

memory capabilities
