It is possible that the damages could cause more firefighters to be called to the scene, or that the number of firefighters could cause more damages to the property in the course of fighting the fire. However, the relationship between the two could also be influenced by a lurking variable, such as the size of the blaze. Therefore, option E is the best choice as it acknowledges the possibility of multiple cause-and-effect relationships, as well as a lurking variable.
