What was the biggest problem Giovanni Verrazano faced on his voyage?

The biggest problem Giovanni Verrazano faced on his voyage in 1524 was navigating the treacherous waters of the North American coast, which were largely uncharted at the time. Additionally, he encountered resistance from Indigenous peoples, who were often wary of European explorers. Verrazano also struggled with limited supplies and the challenges of maintaining the morale and health of his crew during the lengthy expedition. These factors combined posed significant threats to the success of his mission.
