Chattogram Board 2023

Mim goes to the Chattogram Hill Tracts with her family. There she sees fuel energy being produced by building a dam across the course of a main river. Which field of the river's role did Mim visit?

Think it through first, then pick an option.

  1. a trade
  2. b minerals
  3. c communication
  4. d hydroelectricity
Answer and explanation

Correct answer: d hydroelectricity

Producing power by a dam on a river's course with a turbine is hydroelectricity, which is done at Kaptai in the Hill Tracts.

Why the other options are wrong

  • a trade: Trade is carrying goods by waterway; making power with a dam is not trade.
  • b minerals: Minerals lie under the ground; they are not made with a river dam.
  • c communication: Communication is carrying people; making power with a dam is not communication.
