which of these fits best in the empty box?\n○a. higher interest rates\n○b. lower economic efficiency\n○c. lower physical capital\n○d. higher standard of living
Answer
Brief Explanations:
Investment can lead to increased productivity. Higher productivity generally results in a higher standard of living as more goods and services can be produced and consumed. Higher interest rates are not a direct result of increased productivity. Lower economic efficiency is contrary to what increased productivity implies. Lower physical - capital is also not a logical follow - up to increased productivity.
Answer:
D. higher standard of living
