A scientist wants to use a model to help present the results of his detailed scientific investigation. Why would a model be useful?

A model can represent a complex idea or process in a simpler, more visual way, helping an audience understand the investigation’s results. The best choice is “because the model makes the concepts easier to understand.” A model does not prevent questions, and being easy to assemble or requiring full attention is not the main reason to use one.
