Final answer:
Studying the rings of Saturn would be most useful in helping us answer the question: Why do some jovian planets in our solar system have rings while others do not?

The study of Saturn's rings would be most useful in helping us answer the question: Why do some jovian planets in our solar system have rings while others do not?
By studying Saturn's rings, we can gain insights into the formation and composition of planetary ring systems. The rings of Saturn are made up of countless small bodies ranging in size from mountains to mere grains of dust. They are influenced by the pull of the moons that also orbit Saturn.
In contrast, other jovian planets like Uranus and Neptune also have ring systems, but their particles are black, unlike the bright particles in Saturn's rings. This difference in the color and composition of the ring particles can provide valuable information about the origin and evolution of ring systems in different planets.
