Answer to Question 1

C
When the chest wall moves, so do the lungs because the lungs are attached to the inner wall of the thoracic cavity by the outer layer of the pleura. Before inspiration, the pressure inside the chest cavity is negative. During expiration, the muscles relax, decreasing intrathoracic pressure to allow the air to escape into the atmosphere. During inspiration, the chest wall expands.

Answer to Question 2

C
A grand theory is composed of concepts representing global and extremely complex phenomena. Another name for a low middle-range theory is a practice theory that deals exclusively with one specific phenomena.
