In fugard’s "master harold"…and the boys, hally’s mother’s repeated phone calls contribute to what structural element of the play?

Climax, falling action. resolution, and rising action are the choices. If so then i would say RISING ACTION because it shows that when Hally's mother calls, the plot seems to be going somewhere is if it is LEADING to something significant in the story such as his father coming home. It cant be climax because she calls multiple times through the story. It cant be resolution because she calls WAY before the climax is resolved. So based off of process and elimination alone I am almost certain that rising action is correct.

Hope my thinking process helped.
