Video Summary
Chloe uses two machines, R and S, to transform a square sheet of paper. Machine R rotates the paper 90 degrees clockwise, while machine S stamps a club symbol on it. To determine the sequence used to obtain a final image with a club symbol noticeably rotated, we work backwards. Initially, the paper appears rotated, indicating the last machine used was R. Before this, the club symbol was stamped by machine S. The initial paper orientation was achieved by first using machine R. Thus, the sequence of machine usage is R, S, R, corresponding to answer B.
