What must Mr. Jones do to allow parents to see the new calendar?

To enable parents to view the new calendar, Mr. Jones must make it public. A public calendar allows anyone with the link or access to the calendar to view the events and updates without needing specific permissions. This approach is especially useful for sharing information with a broader audience, such as parents, who may not all have direct access to the calendar if it were set to private or shared individually.

Making it private would restrict access to only those individuals Mr. Jones chooses to share it with, thereby preventing parents from viewing the calendar. Sharing it individually would entail managing each parent's access separately, which can be cumbersome and less efficient, especially for a larger group. Printing out the calendar, while providing a physical copy, would not facilitate real-time updates or online access for parents. Therefore, making the calendar public is the most effective way to ensure that all parents can see and stay informed about the events.
