Which evidence from the text "Lake Titicaca" by Miguel Ángel Asturias supports the inference that Lake Titicaca's waters must have special powers?

"Water in which the armor of the Incan empire’s conquistadors has not rusted. And it has been entombed already for centuries in its profound vase."

"I saw, as the sun was setting, the conquistadors’ steel shadows sink in search of the city of gold, hidden by the waters of this Andean sweet-lake sea."

"Waves of gigantic, seamless mass from the Cretaceous that become, at the height of the American world, the fairest crown of water: Titicaca."

"Mineral water. Other American lakes have vegetable waters. The sun knows it. And it is not a heavenly body, but a foundry in the west."
