Sonia is adapting the following scene into a sketch for her school’s drama club. Compare her version to the original:

Original: Rory stood pensively before the wall, which towered many dozens of feet high and had, so far as he could tell, no doors, no notches, no features of any kind. How frustrating, and yet, it was certainly a challenge.

Staged: (RORY and BELINDA stare up at a wall—it is high enough that its top cannot be seen on stage.) BELINDA: How many feet high is it, do you think? RORY: (excitedly) Dozens, I should think! No less than 60. BELINDA: There must be some kind of door! Or notches, or dents, something to climb . . . RORY: (gleeful) No, nothing of the sort. No features of any kind—look! BELINDA (pouting): How tremendously frustrating! RORY: Ah, but what a delicious challenge!

Which of the following best describes how adding a second character affects the scene?
A. The second character helps to resolve the conflict.
B. The second character helps to develop the setting by describing it aloud. C. The second character helps develop Rory’s character by acting as a contrast to him.
D. The second character helps to develop the plot by introducing important background information.
