Q1. Which pair best matches a major hydel dam with the river it mainly impounds in Pakistan?
Answer: Tarbela on Indus
Explanation: Tarbela Dam, completed in 1976, is built on the Indus River in Khyber Pakhtunkhwa and remains one of the world's largest earth-filled dams by structural volume. Mangla Dam is on the Jhelum River, not the Chenab, making the Tarbela–Indus pairing the only correct match among the options.
