Question from UPSC Prelims 2020 GS Paper


1. Mekong — Andaman Sea:

The Mekong River actually flows into the South China Sea, not the Andaman Sea. Therefore, this pair is incorrectly matched.

2. Thames — Irish Sea:

The Thames River flows through southern England, including London, and eventually empties into the North Sea, not the Irish Sea. This pair is also incorrect.

3. Volga — Caspian Sea:

The Volga River is the longest river in Europe and it does indeed flow into the Caspian Sea. This pair is correctly matched.

4. Zambezi — Indian Ocean:

The Zambezi River is one of Africa’s longest rivers and it flows into the Indian Ocean. This pair is correctly matched.

Given the analysis above, the pairs that are correctly matched are:

  • Volga — Caspian Sea
  • Zambezi — Indian Ocean

Therefore, the correct answer is:

c) 3 and 4 only
