(20 10? Huishan District Simulation) On the right side of the cartoon "Go Left, Go Right", the shadow on the ground indicates that the light is _ _ _ _ _ _; This box is relatively _ _ _ _

Shadow means that light passes through an opaque object and forms a shadow behind the object, which shows that light travels along a straight line.

So the answer is: people who drive in a straight line, go left.
