Imagine that a group in the local community decides to launch a campaign to clean up a nearby park and enhance its facilities. They want to create a vibrant space for everyone to enjoy. The organizers attempt to gain a large turnout to ensure the success of the project. However, they are concerned about the possibility of free ridersindividuals who may not contribute but still benefit from the improved park. Choose the option that reflects the best strategy to control the number of free riders while also creating a positive atmosphere for the social movement to succeed. Ignore the issue, assuming that community members will naturally feel compelled to contribute to the common cause. Offer rewards and recognition to those who actively participate in the cleanup and enhancement efforts. Implement a mandatory participation rule, requiring every community member to contribute a certain number of hours to the project
