Final answer:
Understanding something from a brain of reference means creating a mental prototype based on past experiences. An example is thinking of a dog based on the first breed one has encountered.
Step-by-step explanation:
When we talk about understanding something from a brain of reference, it means looking at a concept or idea based on our own previous experiences, knowledge, and beliefs. Our brain creates a kind of mental prototype or representation of a concept based on our past encounters with similar things. For example, if someone grew up with a pet dog, their prototype or mental image of a dog may be a Golden Retriever, because that was the first breed they encountered.
