Cory is using the web below to organize his idea for his essay about the 1871 Chicago fire after reading The Great Fire by Jim Murphy. A circle is labeled Great Chicago Fire. 3 circles are connected to this main circle. The first is labeled What happened? The second is labeled What were the causes? The third is labeled What were the effects? Which detail belongs in the causes area of the web? Spectators watched as the blaze grew. Gusty winds made flames spread rapidly. Many people lost their businesses. People were scared and fled their homes.
