You "measure" or "observe" two events to occur at the same time, one nearby and one further away. which one did you actually see first?
a)both at the same time.
b)the closer one.
c)the farther-away one

The one further happened earlier (this is something about Einstein's relativity, a consequence of the limited light speed). If the distances are small enough ("earthly"), they are simultaneous.
If the events work simultaneously, the light from the closer one gets faster to the eye than that of the farther one. In this case, you see the closer one first. If you see them simultaneously, see the first case.

Sorry i don’t know what to do
