Each of the many people who participated in the town' s annual spring cleanup received a community recognition certificate. Because the spring cleanup took place at the same time as the downtown arts fair, we know that there are at least some spring cleanup participants who are not active in the town' s artistic circles. If the statements above are true, which one of the following must be true? ["Some of the persons who are active in the town's artistic circles received community recognition certificates.", 'No person who received a community recognition certificate has not participated in the spring cleanup.', "Not all of those who received community recognition certificates are active in the town's artistic circles.", 'No participants in the downtown arts fair received community recognition certificates.']
