Final answer:
Nancy and Don's wedding decisions are influenced by cultural expectations, gender roles, and religious beliefs, reflecting a mix of traditional norms and personal choices.
Step-by-step explanation:
Nancy and Don's wedding decisions are most influenced by cultural expectations and personal preferences. The desire to have a traditional church wedding with a Roman Catholic priest, as wished by Nancy's mother, reflects traditional gender roles and cultural norms prevalent in many societies.
In contrast, Nancy's interest in an informal beach wedding aligns with contemporary trends among her peers, indicating a shift towards more modern, personalized ceremonies.
Meanwhile, Don's wish to have a Thai monk officiate highlights the diversity of cultural influences and the importance of incorporating personal and familial religious beliefs in wedding planning.
