Final answer:
Spielberg employs foreshadowing when Matt Hooper yells at Police Chief Brody about the compressed tanks, hinting at a later pivotal event in the film 'Jaws'.
Step-by-step explanation:
The term that best explains what Spielberg employs when Matt Hooper yells at Police Chief Brody for accidentally releasing the compressed tanks that could have exploded the boat in the movie Jaws is foreshadowing. Foreshadowing is a literary device that gives an advance hint of what is to come later in the story. In this case, the mention of the compressed tanks sets up the audience for a later event involving these tanks that is pivotal to the film's climax.
