From George's perspective, how fast does a beam of light approach Gracie when she races away at speed $v$ relative to George? That is, from George's
perspective, how quickly does the distance between the light beam and Gracie decrease?

Note: This is a simple, but slightly tricky, exercise. The question is not asking about the speed of light itself. Rather, the question is asking about the speed at which the beam of light approaches Gracie, from George's perspective. While this might sound like an irrelevant distinction, it's not. So ponder this for a moment before selecting your answer.

From George's perspective, if Gracie runs toward him, how fast does the light approach Gracie? (Note: Again, this exercise is not asking about the speed of light itself, but rather the speed at which the light approaches Gracie from George's perspective.)
