    Three of those produce light. Which one does not?

    Sun produces light. So does flashlight and lightning.
    Rule out those, and you've got your answer!

  • Science - ,

    if you can take to away and you are left with lightning and flash light think about it think what one reflects off something

  • Science - ,

    It is cloud probably because the sun produces it's own light, the flashlight has batteries and produces light, and lightning is light! Because of the way the clouds fall on a certain day you may only see them at a certain time of day or when the light reflects off it from another light source. At first I thought it was flashlight because in the book it does not say if the flashlight is on or off and that could change the whole answer!
