Which best describes the suspense technique of flashback? an image, color, object, or similar is shown early in the film. it later reappears in a pivotal scene or plot point. details of the story outside of the chronological storyline are provided to the audience, often as a memory. illusions of explosions and other events are presented, often using computer-generated imagery to seem realistic. the screenwriter lets the audience know something the main character does not, usually something important to the plot.
