Final answer:
Low tax and interest rates are economic factors that contribute to the stability of a society because they encourage investment and growth, which lead to economic stability.
Step-by-step explanation:
The question asks which of the following is an economic factor that contributes to the stability of a society: fluctuating prices, low tax and interest rates, a strong sense of duty, or a strong military. The correct answer is low tax and interest rates. Economic stability is achieved when key factors such as consistent economic growth, low and consistent unemployment rates, and stable prices are maintained.
Governments play a significant role in stabilizing the economy by adjusting fiscal and monetary policies, like reducing taxes for businesses to encourage investment, which can lead to economic growth. The trade-offs that must be considered often involve determining which economic goals hold the highest value such as efficiency, freedom, security, equity, and growth. While a strong military can contribute to a country's overall security, it is not directly linked to economic factors contributing to stability.
