Two conceptual physics questions?

[JC Denton]

I need some help on these questions:
1) "In 2004 when Mercury passed between the sun and Earth, light was not appreciably bent as it passed Mercury. Why?"

2) "During the first second of its flight, a bullet fired horizontally drops a vertical distance of 4.9m from its otherwise straight-line path in a gravitation field of 1 g. By what distance would a beam of light drop from its otherwise straight-line path if it traveled in a uniform field of 1 g for 1 s? For 2 s?"
