Concept:A settlement grows quickly when it is positioned where transport routes meet.
Explanation:IREWA is a nodal town because several routes converge at this place.
Roads from surrounding areas join together at IREWA.
This junction becomes an important centre for transport and communication.
It also acts as a market where people from nearby villages come to trade.
The movement of people and goods encourages business activities to develop.
New services such as shops, workshops, and transport facilities appear over time.
This attracts more people to settle there permanently.
The growing population and economic activities lead to further expansion of the town.
Although factors like good climate and agriculture may contribute, the map clearly shows route convergence as the main reason.
Therefore, IREWA's growth is best explained by its position as a nodal point.
