Why were the first two attacks in the movie jaws so close together?

The first two attacks in "Jaws" occur close together to establish a sense of urgency and danger in the narrative. These attacks quickly escalate the tension and highlight the shark's predatory nature, emphasizing the threat to the community. Additionally, the rapid succession of attacks serves to motivate the characters, particularly Chief Brody, to take action against the shark, setting the stage for the film's central conflict.
