​A.) Why did the scientists describe the pools as a "lost world"? Please elaborate on your answer.

 Many years ago,  some novelists wrote books about expeditions for the unmapped areas of Central  South America and Amazon.

 The lagoon area scientists recently found in the Atacama plateau seems to be similar to the scene of novels.

So they might call it a lost world.  ✔️
