The following activity will take you through a presentation that will explain the various rules changes that have occurred over the past six years. By default, the presentation is set to auto advance slides after one minute. You can also use the right and left arrows in the lower left corner to navigate back and forth between slides. Once you have reviewed the entire presentation, you will then be asked to answer four questions to receive credit. A link to the quiz will be provided at the end of the presentation. Please review all the slides carefully and then choose the best answers for the questions provided.
