Answer :
According to the TED-Ed video, Lord of the Flies begins with dark and ominous black, bat-like shadowy imagery from Jack and his choir.
In the novel "Lord of the Flies" by William Golding, the opening scene describes a group of boys who find themselves stranded on a deserted island after a plane crash. Among these boys are Ralph, who becomes the elected leader, and Jack, who leads a choir group.
The imagery of dark and ominous black, bat-like shadows is associated with Jack and his choir. In the story, Jack and his choir are initially depicted as disciplined and orderly, wearing their choir uniforms. However, as the narrative progresses, Jack's group becomes increasingly associated with savagery and violence.
