The event that does not occur during exhalation in human beings is "The volume of thoracic cavity increases".

Here's why:

1. The inter-costal muscles pull the ribs inwardly: This is true. During exhalation, the intercostal muscles relax, causing the ribs to move inwardly and downward, reducing the space in the chest cavity.

2. The volume of thoracic cavity increases: This is false. During exhalation, the volume of the thoracic cavity decreases as the air is pushed out of the lungs.

3. High pressure area is created inside the thoracic cavity: This is true. As the volume of the thoracic cavity decreases, the pressure inside increases, which helps to push the air out of the lungs.

4. Diaphragm becomes dome-shaped: This is true. During exhalation, the diaphragm relaxes and returns to its dome-shaped position, reducing the space in the chest cavity.
