What led to the Spanish Portuguese becoming dominant languages in Latin America?

1. Indigenous languages did not have the necessary vocabulary to become a common language compared to Spanish and Portuguese.
2. Indigenous people adopted European languages because they were seen as a superior to their own.
3. Musicians wanted to entertain European audiences in their own language.
4. Missionaries use Portuguese languages as a part of their conversion of indigenous peoples.

The correct choices are:

1. Indigenous languages did not have the necessary vocabulary to become a common language compared to Spanish and Portuguese.
2. Indigenous people adopted European languages because they were seen as superior to their own.
4. Missionaries used Portuguese languages as part of their conversion of indigenous peoples.

These factors played a significant role in the dominance of Spanish and Portuguese in Latin America. Indigenous languages often lacked the vocabulary and structures necessary for widespread communication and administration, making it difficult for them to serve as common languages. Additionally, European languages were often perceived as superior and prestigious, leading indigenous people to adopt them for social and economic mobility. Missionaries also played a role in spreading Portuguese and Spanish, using these languages in their efforts to convert indigenous populations. The option concerning musicians wanting to entertain European audiences doesn't directly relate to the dominance of Spanish and Portuguese as languages in Latin America.
