Answer to Question 1

Craters are the rule...everybody was a target in the early days of accretion. The longer the surface has sat without internal deformation, the more impacts have cratered the surface. If craters are absent, it is because other processes, such as lava flows or erosion, have replaced the older cratering.

Answer to Question 2

B
