Answer:
The rising action of a story builds the reader's interest in the characters, their problems, and the plot itself, culminating in a climax. Your climax will be less engaging and exciting if there is no increasing action, and your story's end will have less emotional weight. A short story's growing action propels the plot toward the climax.
Exertion maybe?
I think it might be exertion because it seems to fit... tell me if I'm wrong.
