UNIDAD 9 VARIABILIDAD Y SESGO

Conflict is present everywhere in the world around us. We experience conflict on a daily basis, and it can be minor or major.

Conflict in a story is a struggle between opposing forces. Characters must act to confront those forces and there is where conflict is born. If there is nothing to overcome, there is no story. Conflict in a story creates and drives the plot forward.

3.- VARIABILIDAD DEPENDIENTE DE LOS INSTRUMENTOS (INTER E INTRA)

2.-VARIABILIDAD DEPENDIENTE DE LOS OBSERVADORES (INTER E INTRA)

In this type of conflict, a character must take on society itself, and not a single person. The character stands at odds with societal norms and realizes the necessity to work against these norms. This is an external conflict.

1.-VARIABILIDAD DE LOS SUJETOS (INTER E INTRA)

This situation results from a protagonist working against what has been foretold for that person. While this conflict was more prevalent in stories where gods could control fate, such as in ancient Greek dramas, there are still examples of this type of conflict in more contemporary literature.
