The main character, Phileas Fogg. He showed us that he was the most determined person in the novel is because that he would wager and had the utmost confidence he would be able to travel the world in 80 days. And what does this mean? It means that Fogg really had hopes or himself and was sure that he CAN fulfill his wish, his goal in life. Therefore, I proudly say t hat he is determined for he is an enthusiastic in completing life's toughest task.
Hope this helps.
