The best example of visualizing a sequence of events among the given options is:
b. “Early in the morning, shortly after dawn, while Tito was still dreaming, Bimbo would disappear.”
This statement clearly lays out a time frame (early in the morning, shortly after dawn) and indicates a sequence of events (Tito dreaming and Bimbo disappearing), which helps to visualize the progression of time and events.
While options a and c do describe actions, they are more focused on individual moments rather than a clear sequence. Therefore, the correct answer, specifically exemplifying a sequence of events, is option b.
If you're looking for visualizing sequences among all statements, "d. all of the above" could be a consideration since all examples describe actions occurring. However, "b" provides a more explicit sense of temporal progression.
