what are the two key factors that determine global population growth rates? temperature and weather…

Brief Explanations:

To determine global population growth rates, we analyze the options: Temperature and weather (first option) don't directly drive population growth. Education and economics (second option) are indirect factors. Pollution and other hazards (fourth option) impact health but aren't the key determinants. Birth rates (number of births per unit time) and death rates (number of deaths per unit time) directly calculate population growth (growth rate = birth rate - death rate), making them the key factors.

Answer:

C. birth rates and death rates
