While reading a magazine, a drop of water from a drinking glass falls onto the page and lands on the print appears bigger underneath the drop of water, because...

• The water refracts the light from the room causing the print to appear bigger.

• The water reflects the light form the room causing the print to appear bigger.

• The water absorbs the light from the room causing the print to appear bigger.

• the water repels the light from the room causing the print to appear bigger.
