Which of the following statements best describes the link between poverty and brain development based on the material?

• A. Physiological differences exist in the brains of children raised in poverty.
• B. Poverty enhances cognitive abilities.
• C. Nutritional deficits are irrelevant to brain function.
• D. Safety concerns do not influence neural outcomes.

Answer: (A)

Poverty can shape brain development through physiological changes driven by chronic stress, inadequate nutrition, and fewer stimulating experiences. When children grow up in poverty, persistent stress activates the body's stress response, releasing hormones like cortisol that can affect brain circuits involved in attention, learning, and self-control—areas such as the prefrontal cortex and hippocampus. Nutritional deficits common in low-income settings influence myelination and neurotransmitter production, impacting how efficiently neural networks develop. A less enriched environment with fewer language-rich interactions also shapes neural connectivity and cognitive function. All these factors contribute to physiological differences in the brains of children raised in poverty, which is why this option best describes the link.

Phrases suggesting poverty enhances cognitive abilities aren’t supported by the material, and the idea that nutritional deficits don’t matter contradicts established evidence. Safety and stability do influence neural outcomes, so dismissing their impact wouldn’t fit the topic.
