Question

1. a(n) ____ can cause the ppf to expand. natural disaster destroying factories and infrastructure improvement in production technology workforce that is shrinking due to an accelerating death rate decrease in the rate of inflation

Explanation:

The Production - Possibility Frontier (PPF) expands when there is an increase in resources or an improvement in technology. A natural disaster destroying factories and infrastructure reduces resources, a shrinking workforce due to a high death - rate reduces labor resources, and a decrease in inflation rate has no direct impact on production capacity. An improvement in production technology allows more output to be produced with the same amount of resources, causing the PPF to expand.

Answer:

improvement in production technology
