Final answer:
The coastguard's initial reaction to the Geats landing is not explicitly described in the excerpts; rather, the narrative focuses on the anticipation and actions of the shipwrecked seafarers seeking rescue.
Step-by-step explanation:
The coastguard who first sees the Geats land in the literary context provided appears to be cautious and observant. The excerpts, drawn from a narrative, depict seafarers in a dire situation seeking assistance from the coast. Repeated references to the lighthouse and life-saving efforts indicate that the characters are in search of rescue. The coastguard presumably would have played a key role in orchestrating the rescue efforts and in being vigilant to spot any incoming vessels or people in distress. However, the actual attitude of the coastguard is not specified in these excerpts, reflecting more on the anticipation and actions of the shipwrecked individuals and less on the coastguard's initial reaction to their landing.
