We propose that agents may use abductive reasoning to adopt a Cooperative Answering behavior. In the event of failure or inadequacy of answers to a query (question), the agent should provide related answers by employing Query Relaxation. These answers are to be related to the query and might be useful to the querying agent. In order to achieve that, we consider agents with knowledge bases consisting of Abductive Logic Programs. Such agents are able to explain failure and guide the search for related answers. A distinctive aspect of our proposal is that in order to avoid undesirable results, one can select the parts of the query that cannot be relaxed.
