Answer:
The correct answer is D. All of the above.
Step-by-step explanation:
A sequence of events means that we are shown what events happened one after another. The examples should give us a clear picture of what happened, who did what and when, and even perhaps why.
As you can see in all examples above, that is exactly what happened:
A) Something was happening and then he started hearing sounds
B) He was doing something and then went to sleep
C) Tito was sleeping and then something disappeared
All examples show us a sequence of events.
