A flashlight is a human-made object, so this gives us evidence or proof that humans can make light sources. The Sun and lightning are both natural sources of light, so nature, not humans, created them.

The candles on the top illuminate this cake. From the picture, we can observe that the only source of light is coming from the candles, and without them, it would be dark. The background of the picture is dark, so there are no other sources of light.

The sentences that provide evidence of a light source are necessary are, "Once the cave was illuminated with the flashlight, she saw there were tons of snakes! The flashlight went out, and it was dark again.". These sentences explain that once the flashlight illuminated or light up the cave, she could see the snakes. It also states that it went dark again when the flashlight went out. This shows readers that the flashlight is where the light came from and was needed to see in the darkness.

Providing evidence is like giving proof of something or for something. In this short passage, two sentences show us how light is needed to illuminate and see objects in the dark. "When she gets outside, it is so dark she can't even see her feet! She turns on the lantern and can see all the bugs crawling on the roots of a tree." The first sentence lets us know it is dark, and she cannot see anything, not even her feet. In the second sentence, she illuminates the area around her with the lantern so she can see the bugs and roots. These sentences show that light is necessary to see.

Andrew should choose the flashlight if he wants to get an item to help him see. A lightbulb will not work without electricity, so holding it up outside will do nothing. A candle will give off light to reflect off objects but only for a short distance, and he is on the end of a very long sidewalk. A flashlight would help him see the long-distance that is needed. It will reflect light off of the objects in the dark so he can see what is around him and if his friend is coming.

Humans can only see objects when they are illuminated by something that gives off or produces light. Fireworks do both of these things, so they help to light up the night sky and other objects around them. While waiting for a firework show, you may notice it is dark and hard to see the people around you; when the fireworks explode, you can see the people around you more clearly.
