Cynthia was a shy girl. She believed that she was plain and untalented. One day her teacher ordered the entire class to show up for audition for the school play. Cynthia nearly died of fright when she was told that she would have to stand on stage in front of the entire class and deliver dialogues. The mere thought of it made her feel sick. But a remarkable transformation occurred during the audition. A thin, shy girl, her knees quaking, her stomach churning in terror, began to stun everyone with her excellent performance. Her bored classmates suddenly stopped their noisy chat to stare at her slender figure on the stage. At the end of her audition, the entire room erupted in thunderous applause.
Cynthia's classmates were chatting because

Correct Option (B)

The passage explicitly states, "Her bored classmates suddenly stopped their noisy chat..." This phrase directly indicates that the classmates were experiencing boredom, which led to their chatting. The cessation of their noisy chat upon Cynthia's excellent performance further confirms their initial disinterest in the ongoing auditions.

Incorrect Options:

• Option (A): The passage provides no information to suggest that the classmates were chatting because it was their turn to perform next. This is an unsupported inference.
• Option (C): The classmates' chatting occurred prior to Cynthia's performance, as indicated by their sudden silence once she began to perform well. Therefore, their chatting could not have been a reaction to Cynthia's acting, which had not yet taken place.
• Option (D): The passage does not offer any details regarding the teacher's control over the students. This option introduces an external factor not supported or addressed by the given text.
