Final answer:
John White was sent to Roanoke to try again to start a colony for a second time, but the colony was eventually abandoned.
Step-by-step explanation:
The person who was sent to Roanoke to try again to start a colony for the second time was John White. In 1587, he led a group of about 150 settlers to establish a colony on Roanoke Island. However, due to supply shortages, White had to return to England for additional support and was stranded there for several years. When he finally returned to Roanoke, the colony was abandoned.
