Final answer:
Without specific details on Marsha's behaviors or the situation at hand, it's challenging to ascertain her conflict management style or its impact on events. Marsha's methodical use of evidence suggests a collaborative approach, but more information is required for a precise assessment.
Step-by-step explanation:
To assess Marsha's conflict management style, it is necessary to identify her approach among the common conflict resolution strategies. These strategies include avoidance, accommodation, competition, compromise, and collaboration. Without direct information about Marsha's actions, we cannot categorically identify her conflict management style. Considerations can be made based on the context provided Marsha uses evidence and comparison in her analysis, suggesting a methodical and possibly collaborative approach. However, due to the lacking specific context about her conflict management behaviors, we cannot determine how her style has influenced events definitively. It is crucial in conflict resolution to be adaptable and evolve one's approach based on the circumstances, which could alter how one's style influences situations.
