Caroline Edwin strolled around the classroom, then returned to her seat and picked up an extra test paper, browsing through it casually.
The front of the test paper was filled mostly with multiple-choice questions.
The first question: Within the atmosphere, what is the air density?
Four options were provided, and the correct one needed to be selected and filled in.
There were ten multiple-choice questions in total, each worth two points, making them relatively easy to score.
Caroline Edwin, resting her cheek on one hand, fixed her gaze on option C without any hesitation, which stated it decreased with increasing altitude.

After roughly browsing through the test paper, she put it down and continued to patrol the classroom.
Stopping by Rita Webster's side, she paused and scrutinized the answers on the test paper; Rita had answered all ten multiple-choice questions correctly.
