Final answer:
External events and internal events are different types of occurrences. External events happen in the physical world, while internal events happen within a person's mind.
Step-by-step explanation:
External events and internal events are two different types of occurrences. External events refer to situations or incidents that happen outside of a person's mind, while internal events happen within a person's mind or thoughts.
An example of an external event could be a thunderstorm or a car accident. These are events that occur in the physical world and are observable by others.
On the other hand, an internal event could be a person having a dream or feeling happy. These events are subjective and can only be experienced or known by the individual.
