Final answer:
The article's main purpose was likely to clarify that the Pilgrims were not the first European settlers in the New World and to recount the various interactions between earlier European explorers and Indigenous peoples.
Step-by-step explanation:
The author's purpose for writing this article was most likely to explain that the Pilgrims were not the first to settle in the New World and to describe the interactions and celebrations that occurred between European settlers and the Indigenous peoples prior to the Pilgrims' arrival.
This is best reflected in option B, as the article discusses various instances of early European interactions in the New World, such as the experiences of Álvar Núñez Cabeza de Vaca and his praise for the hospitality of the Indians of Florida, the founding of St. Augustine by Pedro Menéndez de Avilés, and mentions of the relationship between the Pilgrims and the Indigenous peoples they encountered.
The purpose is not to suggest serving historical Spanish foods at Thanksgiving, as indicated in option C, nor does it focus exclusively on the Timucua's welcoming or Menéndez de Avilés's childhood and military successes, which rules out options A and D.
