Answer :
In relation to the religiosity of indigenous peoples during this period in Brazilian history, we can evaluate the statements provided:
a) (F) The Portuguese did impose their religious dominance with the aim of making the natives "submissive" or docile to their rule. This statement is false as the Portuguese often attempted to convert indigenous peoples to Christianity, which was a way to exert control over them rather than respecting their existing beliefs.
b) (V) Initially, the first Portuguese explorers acknowledged that the indigenous peoples had their own religious beliefs, and they believed in respecting them. This statement is true because there was an understanding that indigenous peoples had their own spirituality before European contact.
c) (V) Indigenous peoples did express their religiosity through mythical beliefs and rituals. This statement is true as many indigenous cultures had intricate belief systems and ceremonies that were central to their way of life.
By examining the provided statements, we can see that the Portuguese interactions with indigenous religious practices were complex, involving both attempts to impose Christianity and some initial respect for indigenous beliefs. Indigenous peoples did indeed exhibit their spiritual beliefs through myths and rituals, showcasing the diversity and depth of their religious traditions during this period in Brazilian history.
