1 point
a. inform the reader about the uncontacted peoples of brazil.
b. persuade the reader to take action in order to protect uncontacted peoples.
c. describe to the reader how uncontacted peoples live.
d. inform the reader about government programs to protect uncontacted tribes in brazil.

Explanation:

To determine the author's main purpose, we analyze each option:

• Option a: If the article's focus is on providing information about uncontacted peoples of Brazil (e.g., their existence, context), this fits "inform".
• Option b: "Persuade to take action" implies a call to action, but the question doesn't suggest advocacy.
• Option c: "Describe how they live" would focus on lifestyle details, not just informing about their existence.
• Option d: Focuses on government programs, but the question is about the author's main purpose regarding the article, and "inform about uncontacted peoples" is broader if the article introduces them. Assuming the article's core is to inform readers about these groups, option a is correct.

Answer:

a. inform the reader about the uncontacted peoples of Brazil
