Answer:
three attempts
Step-by-step explanation:
Modern-day Carolina, particularly North Carolina was famously known as Roanoke Colony or Lost Colony.
At first attempt, in 1584, led by Phillip Amadas and Arthur Barlowe, the voyage report led to Sir Walter Raleigh to establish a colony in the Roanoke Island by 1585. However, due to an inadequate supply of food and bad relationships with the natives, the colony left the island.
At the second attempt, the expected ship that was supposed to be addendum settlers to the first settlers met the island empty. This led them to leave some men on the island, in the hope they will come back with more settlers within a short period. However, when they failed to come, those few men also left the island.
At the third attempt, in 1857, another group of settlers went there led by John White, and after a few periods of stay on the island. John White left for England to have resupply of foods and materials. However, he came back three years after finding the location empty with nobody there.
