Answer

Event 1 occurred after event 2.

Work Step by Step

The light from event 2 takes longer to reach you than the light from event 1, because the light from event 2 travels a longer distance. Since the light from both events reaches you at the same time, the light from event 2 must have started at an earlier time than event 1. Therefore, event 1 occurred after event 2.
