Final answer:
Information on the first European ships sailing the upper Atlantic would best be placed in the "Swarms of Settlers Arrive" section, discussing colonization and settlement in the New World.
Step-by-step explanation:
The section of the article that would best fit information about the first European ships sailing the upper Atlantic coast would most likely be "Swarms of Settlers Arrive." This section would cover the arrival of European settlers in the New World, their impact, and the expansion of settlements as a direct result of exploration and colonization. The reference to European ships, such as those under the command of Captain Christopher Newport, heading towards the New World with colonists onboard, fits well within this theme of settlement expansion and the associated movements of people and cultures.
