Answer:
a description of the event as Arnetta experienced it.
Step-by-step explanation:
The fact that the statements were in quotes is a reflection of the fact that they were the words of Arnetta and they were expressions of her feelings. The first statement in quotes- "It's here, it's about to happen!", were thoughts going through her head. The second statement in quotes- "seeing all those children coming out to participate in the Movement", was what she saw.
The last statement, "running around like a chicken with his head cut off", was a description of how she saw the principal running around. So, all of these were descriptions of the event as Arnetta experienced them.
