Final answer:
Based on the information provided, the last section suggests that political polarization and differing interests make long-term planning difficult, and therefore none of the specific options about Chile's future political direction or support for indigenous rights is directly supported by the text.
Step-by-step explanation:
The last section suggests that there is no prospect for a long-term plan within a country due to political polarization, the interests of the powerful and wealthy, and the reluctance of people to embrace austerity.
This context does not directly provide information to denote that Millaray plans to run for political office, that Chile will keep its current constitution for a long time, or that there's a rise in support for indigenous rights in Chile.
Therefore, the most suitable answer, based on the information provided, would be none of the above.
This increased political freedom has allowed for the emergence of indigenous rights movements. The passage does not mention any plans for running for political office by Millaray or the long-term status of Chile's constitution.
