Verified step by step guidance

Identify the only freely moving bone in the skull. In human anatomy, this bone is the mandible, which is the lower jawbone.

Understand the function of the mandible. It is primarily involved in movements such as opening and closing the mouth, which are essential for chewing.

Consider the activities listed in the problem: humming, chewing, crying, and sneezing. Determine which activity involves significant movement of the mandible.

Recognize that chewing involves the movement of the mandible as it allows the mouth to open and close, facilitating the grinding and breaking down of food.

Conclude that the activity associated with moving the only freely moving bone in the skull, the mandible, is chewing.
