Explanation
Statement 1 is incorrect: The Mekong River originates in the icy headwaters of the Tibetan highlands.

It empties into the South China Sea through the Mekong Delta in southern Vietnam.
Statement 2 is incorrect: The Thames flows into the North Sea, not the Irish Sea. It is a major river in England, flowing through London. The Thames flows into the North Sea via the Thames Estuary.

It flows into to the Indian Ocean. The river is known for the Victoria Falls, one of the largest and most famous waterfalls in the world.
