Step-by-step explanation:
A) Greater access to healthcare resources was not one of the reasons deary proposed to explain why those with higher intelligence tend to be healthier and live longer.
Deary proposed three reasons to explain the relationship between higher intelligence and better health and longer lifespan: cognitive reserve, better decision-making abilities, and the idea that illnesses in adolescence and early adulthood might have influenced both intelligence and health.
It is important to note that while there is a correlation between intelligence and health, it does not imply causation.
