Answer: Purchasing construction equipment

## Explanation **Purchasing construction equipment (Option C)** is least likely to create a sustainable increase in economic growth because: - **Building a new university (Option A)** represents investment in human capital, which enhances labor productivity and creates long-term sustainable growth through education and innovation. - **Improving the electrical grid (Option B)** represents infrastructure investment that enhances productivity across multiple sectors of the economy, creating sustainable growth through improved efficiency. - **Purchasing construction equipment (Option C)** is primarily a capital investment that may boost short-term construction activity but doesn't fundamentally enhance the economy's productive capacity in a sustainable way. It represents investment in physical capital without necessarily improving technology, human capital, or infrastructure that drives long-term growth. Sustainable economic growth typically comes from investments in human capital, technology, and infrastructure that increase the economy's productive capacity over the long term.
