A teacher tries to help a student recall an event that took place during a field trip to the natural history museum by saying, "Remember, it was the time when you went off to see the skeletons." Which memory component was most directly involved?
A) Semantic memory
B) Short-term memory
C) Massed practice
D) Episodic memory

The answer is D) Episodic memory.

Explanation:

Episodic memory refers to the ability to remember certain events in a person's life. These memories may be general or specific. For example, when you remember your first day at school (the environment, your partners' attitudes, the face of your teacher) specific episodic memory is a work; on the other hand, general episodic memory would store your overall experiences at school, over the years.
