the switch is open
the switch is closed
the switch is black
the switch is not there

A student placed a pencil in a cup of water. The pencil appears broken because light
always travels in a straight line.
bends when it passes through water.
makes the water in the glass evaporate.
reflects the pencil on the water's surface.

it is bent towards the normal.
it always lies along the normal.
it is unaffected.
it is bent away from the normal.
