Step-by-step explanation:
The statement that happiness derived from helping your grandmother learn to use her new iPad can boost your health more than happiness derived from other sources such as material gains (unstated but implied) is true based on the context provided. This taps into the concept that there are different types of happiness, and the ones tied to social connections and altruism can have a more profound impact on our health. In studying the correlation between types of happiness and health, a positive correlation suggests that as one variable increases, so does the other, indicating potential health benefits to the variable under investigation such as prosocial behavior.
