Passag1?

Simulations indicate, and observations confirm, that the particles constituting Saturn's rings are giving up angular momentum to moons of the planet. The simulations predict that over just a few hundred million years, the related energy transfer will cause the rings' collapse. An analogous process occurs around young stars in the disks of matter from which planets emerge, and these protoplanetary disks do vanish that quickly, computer models show. Yet if Saturn's rings are so short-lived, a large comet or moon-the ring’s presumed sourse- must have broken apart in Saturn’s vicinity within the past several hundred million years. That is quite unlikely. It would have much more probable in the young solar system-4 billion years ago or more.?

It can be inferred that the author of the passage mentions protoplanetary disks because?

A. The computer modeling techniques used to study them were later applied to Saturn’s rings?

B. Conclusions about them might reasonably be applied to Saturn’s rings?

C. The accepted understanding of them is challenged by observations of Saturn’s rings?

D. The material of which Saturn’s rings are composed must at one time have been in a protoplanetary disk around the Sun

E. Observations of Saturn’s rings may serve as a substitute for observations of protoplanetary disks
