Humanity's early fire-starting tools may have been dangerous because in the text is says,<span> "It could be lighted only by hard rubbing, and it sputtered and threw fire in all directions." This is dangerous because it would spew fire in all directions and if you think about it, the fire would hit something and then that thing would catch on fire. Lets say you were using the match inside your house. When you strike the match, a spark flies onto the wood floor and your house goes up in flames and you are stuck inside the house with no exit or escape. This may or may not happen, but because of the fire not being contained, there was a chance that you would be harmed.</span>

A plot in a story refers to the events which are connected by cause and effort.
Whereas, subplots exist within the main plot as a side story. It never overpowers the main plot but is connected with the main plot. Events that take place outside the main story are described in subplots. Therefore, the purpose of the subplot is to strengthen the main story line.
Therefore, one reason why subplots are used in novels is to develop the novel's theme in more depth.
