Question

Alvin Yakitori · Accepted Answer

Final Answer : A, Explanation :  Semantic memory refers to our general knowledge of facts and concepts about the world, including information that we did not personally experience or acquire through a specific event or episode. Therefore, Christopher's knowledge about the circumference of Earth falls under the category of semantic memory. Retrograde memory refers to the ability to recall events that occurred before the onset of amnesia or brain damage. Episodic memory refers to the memory of specific personal events or experiences. Implicit memory refers to the ability to remember information or skills without conscious awareness or intention.
