Text: Amazingly, from elephant-back at the jungle's edge you can see the snowcapped Himalayas, less than 160 km (100 miles) away and looming like a foam-crested wave.
Entailment: The Himalayas are less than 100 miles away from the jungle's edge.
Contradiction: To see the Himalayas you must demount your elephant as the high trees obscure your view.
