Question :

In the question given below, a passage is given followed by three statements. Read the passage and answer the question that follows.

It's possible there's a giant, deadly serpent hanging out at the bottom of Fosse Dionne spring in the Burgundy region of France. It's also possible there's not a serpent - it's a legend concocted by ancient inhabitants of the village of Tonnerre where the spring is located - but nobody's ever been able to get to conclude definitely because nobody's ever been able to get to the bottom of it.

I. Fosse Dionne is a karst spring that spews an average of 311 litres of water each second, which is an unusually high discharge rate for this type of spring, whose velocity varies from season to season.

II. There's certainly a lot of water coursing out of it, and like other karst springs, the water emerges from a network of subterranean limestone caves.

III. Two divers undertook navigation in the maze of chambers and narrow tunnels of the spring. Neither of those divers came back to tell what they had seen.

Which of the above statements strengthen the argument in the given passage?
