Read the passage and answer the question.

In 218 B.C., Romans ruled most of the world that they knew about. They felt protected by the Alps – high, snow-covered mountains to the east and north of them that enemies would find very difficult to cross. Then Hannibal came from Carthage, in what is now North Africa, with 9000 infantrymen – soldiers on foot – and something even more surprising: elephants. Hannibal had crossed the Alps with 37 elephants – creatures so terrifying that the Romans, who had never seen such animals, were thrown into a panic.
