Which change would likely lead to the building of a new road in a developing country?

The construction of a new road in a developing country is often prompted by increased economic activity, such as the establishment of new industries or agricultural projects that require improved transportation. Additionally, population growth in a region may create a demand for better infrastructure to connect communities and facilitate access to markets. Government investment in infrastructure development, often spurred by international aid or loans, can also lead to the construction of new roads to support economic growth and improve accessibility.
