Final answer:
Detail B from the options provided seems to best support a point about increasing awareness and connection among indigenous peoples, which relates to themes of solidarity and identity.
Step-by-step explanation:
The question seems to ask which detail from a given text supports a previous answer, which was likely about the themes of solidarity, identity, and advocacy for indigenous peoples. Without additional context, it is challenging to definitely select the best supporting detail.
However, from the provided options, detail B "Another thing that I think has changed is that there's more awareness among tribes of their connections with the outside world with indigenous peoples." (Paragraph 18) seems to relate to the themes of global awareness and connection among indigenous tribes, which could support a point about increasing solidarity or identity amongst indigenous people.
