Final answer:
Sir Walter Raleigh's concerns revolved around establishing a permanent English colony in North America and competing with Spain, both for religious reasons and for wealth gained through privateering. His personal decisions, such as marrying without the queen's permission, eventually led to his downfall, impacting his colonial ambitions.
Step-by-step explanation:
After reading the "Verse Exchange between Elizabeth and Sir Walter Raleigh," the center of Raleigh's concern seems to be the English colonization of North America and the rivalry with Spain. Sir Walter Raleigh was a devout Protestant and he viewed Spanish Catholicism as both a religious and political threat. His privateering activities enriched England and undermined Spanish influence. However, his personal life decisions, particularly his unauthorized marriage to one of Queen Elizabeth's ladies, led to his imprisonment and the loss of favor, which in turn affected his ability to sustain efforts toward colonization. Raleigh had dreams of creating a permanent English settlement in North America, and these efforts were manifested in the expeditions he funded to Roanoke Island, which ultimately faced numerous challenges and setbacks.
