Final answer:
To learn if an author has bias when background information is unavailable, consult their work history, other works, or date of birth.
Step-by-step explanation:
If you couldn't find information about an author's background to learn if they have a bias, there are other reasonable sources you could consult:
- The author's work history: Examining the author's previous works can provide insights into their perspectives and biases.
- Another work by the author: Exploring additional works by the author can help identify recurring themes or viewpoints.
- The author's date of birth: Knowing the author's birth date can provide context about the historical, social, and cultural influences that may shape their writing.
