Q1: Explain how the Dhola Sadiya Bridge has improved the lives of people in Assam and Arunachal Pradesh.

Ans: The Dhola Sadiya Bridge, also called Bhupen Hazarika Setu, connects Assam and Arunachal Pradesh across the Lohit River.

These living structures reflect local knowledge about nature, have cultural meaning, and connect generations.
