a. Star A has a mass of 1 solar mass and star B has a mass of 6 solar masses.
b. Star A has a mass of 20 solar mass and star B has a mass of 6 solar masses.
c. Star A has a mass of 31.2 solar mass and star B has a mass of 5.2 solar masses.
d. Star A has a mass of 22.3 solar mass and star B has a mass of 3.7 solar masses.

Which is Saturn's largest satellite?
a. Ganymede b. Enceladus c. Phoebe d. Titan e. Callisto
Even though Titan has liquid methane on its surface, some internal heat, and plenty of carbon-containing compounds, it is not a suitable place for life because
A) Titan orbits within Saturn's radiation belt so its surface is completely sterilized by high-energy particles B) there is too much volcanic activity on the surface C) it has no ozone layer to protect the surface from harmful UV rays from the Sun D) it is far too cold, and methane is not a very good biological solvent
