Question 2

  D) continuing to shine as stable main-sequence stars.
  E) still on the zero-age main sequence.

Answer to Question 1

As the gas cloud contracts, it spins faster due to conservation of angular momentum. A bulge forms at the equator, which spreads out and eventually forms concentric rings. Each ring forms a planet. This theory explains the observed orbital properties of the planets. The rings formed at the equator and were rotating in the same direction as the gas cloud. This means the planets will all orbit near the plane of the Sun's equator and in the same direction as the Sun's rotation.

Answer to Question 2

E
