Final answer:
The two main destructive patterns of conflict are competition and avoidance, where competition involves an aggressive pursuit of goals at the expense of others, and avoidance leads to unresolved issues due to ignoring the conflict.
Step-by-step explanation:
The question relates to the patterns of conflict, specifically the ones that are destructive. The two main destructive patterns of conflict are competition and avoidance. In competition, parties aggressively strive to achieve their goals, disregarding the interests of others, which can lead to heightened tensions and unresolved issues. Avoidance occurs when individuals or groups deliberately ignore or refuse to address the conflict, which can lead to issues festering over time and a lack of resolution. Both of these patterns contrast with collaboration and compromise, which involve working together to find mutually beneficial solutions.
