The correct answer is C. To describe an event and the reasons the event may have happened
Explanation:
A cause and effect text structure refers to a type of organization and text that has the purpose to describe and explain a specific event or situation and then explores the triggers or causes of the event and the consequences or effects the event has. For example, an author can first describe a fire that occurred in his city, then explore the causes or triggers of it such as weather changes, human activities, etc and finally the effects or consequences including the buildings or area that was affected and whether there was any victim. Therefore, the main purpose of using a cause and effect text structure is to describe an event and the reasons the event may have happened.
