The timeline is a sequentially-ordered view of events. It's generally a graphic design that displays a long bar labeled in dates that are in conjunction with this and often historical events. It includes the "CE/BCE", in which CE implies the traditional era, while BCE implies the current era, and the incorrect choices can be defined as follows:
It doesn't define the causes of incidents
It doesn't connect to the events to each other
It can't describe actions and their impact on a site.
