Thank You, Ms. Sue.

You're welcome.

The meanings of the terms used to construct this sentence are:

B. conquistadors; nomads; indigenous; Mesoamerica

To arrive at this answer, let's analyze each set of terms:

A. Mound Builders; Maya; inhabited; South America
- "Mound Builders" refers to a group of indigenous cultures in North America who built mounds for religious, ceremonial, and burial purposes. However, the sentence does not mention mounds or South America, so this option is incorrect.
- "Maya" is a correct term from the sentence as it refers to the ancient civilization that developed in Mexico and parts of Central America.
- "Inhabited" is a generic term that doesn't specifically point to Mesoamerica, so this option is incorrect.
- "South America" is incorrect because the sentence specifically mentions Mexico and parts of Central America, not South America.

C. friars; spiritual warriors; resided; North America
- "Friars" refer to members of certain religious orders in Christianity. However, the sentence does not mention friars, so this option is incorrect.
- "Spiritual warriors" is not mentioned in the sentence, so this option is incorrect.
- "Resided" is a generic term that doesn't specifically point to Mesoamerica, so this option is incorrect.
- "North America" is incorrect because the sentence specifically mentions the Americas, including Mexico and parts of Central America.

D. Buffalo Soldiers; migrants; existed; West Indies
- "Buffalo Soldiers" refers to African American troops who served in the Western frontier after the Civil War. However, they are not relevant to the sentence, so this option is incorrect.
- "Migrants" is not the most accurate term for the group of people mentioned in the sentence, so this option is incorrect.
- "Existed" is a generic term, and the sentence does not mention it, so this option is incorrect.
- "West Indies" does not align with the land that covered Mexico and parts of Central America, so this option is incorrect.

B. conquistadors; nomads; indigenous; Mesoamerica
- "Conquistadors" were Spanish conquerors during the Age of Exploration, which is relevant to the explorers and soldiers mentioned in the sentence.
- "Nomads" refers to people who have no fixed home and move from place to place, which is relevant to the group encountered by the explorers and soldiers.
- "Indigenous" refers to the original inhabitants of a region, which the group encountered by the explorers and soldiers are.
- "Mesoamerica" accurately describes the region that covered Mexico and parts of Central America where the ancient civilizations of the Aztec and the Maya developed.

Therefore, the correct answer is B. conquistadors; nomads; indigenous; Mesoamerica.
