Answer:
The correct answer is b) longer life expectancy and a higher percentage of the population that is literate.
Step-by-step explanation:
Several studies confirm the correlation of a larger GDP per person with both higher levels of literacy and life expectancy, along with other indicators such as lower levels of poverty and better health conditions. This suggests that, the higher the income of a population is, the better life conditions are. Nevertheless, is worth mentioning that some studies have discovered that, after reaching a certain level, higher income does not translate into higher life expectancy.
