Final answer:
The tension from a betrothal like that of Richard and Alice could manifest in various forms, but historically, a threatened assault on a castle represents an example of tension arising from contested claims, similar to the military and economic conflicts seen during the Hundred Years' War.
Step-by-step explanation:
An example of the tension caused by the betrothal of Richard and Alice, without additional context, cannot be accurately pinpointed. However, if the question refers to historical instances of betrothal leading to tension, a similar scenario is seen during the events leading up to the Hundred Years' War. Military disputes, such as a threatened assault on a castle, are historically accurate examples of tension caused by political and territorial claims, comparable to a betrothal which might be contested or cause offense between noble families or rival nations. The Hundred Years' War, for instance, illustrates military tension and economic conflict due to contested claims to the throne, similar to how the betrothal of Richard and Alice might have escalated to a point where an assault on a castle was deemed a possible reaction.
