Final answer:
José de Escandón significantly influenced the expansion of New Spain by leading the colonization of territories in present-day northeastern Mexico and southern Texas, extending Spain's colonial empire.
Step-by-step explanation:
José de Escandón played a significant role in the expansion of New Spain by being actively involved in the colonization efforts. Escandón is recognized for spearheading the settlement of large areas in what is now known as northeastern Mexico and southern Texas. This expansion led to increased colonial empire growth for Spain in the New World.
During his time, Escandón was known as the 'Father of the Lower Rio Grande Valley.' Under his leadership, the Spanish were able to establish new settlements, which extended Spain's control further into the Americas. His efforts helped reinforce Spanish claims to territory in the New World despite challenges from both indigenous populations and rival European powers. Escandón's influence contributed to the creation of a far-reaching Spanish empire, driven by the objectives of finding wealth and converting native peoples to Catholicism.
Therefore, the correct answer to how José de Escandón affected the expansion of New Spain is: a. Spain colonized most of the New World. This choice aligns with his role in the colonization and expansion of Spanish territories in the Americas.
