Video Summary
Nora is playing a cup game involving flipping and repositioning three cups. After the first three moves, all cups are flipped upside down. Moves four through six reset them to right side up. In moves seven through nine, they become upside down again. The 10th move flips the leftmost cup, resulting in two cups upside down and one right side up. Therefore, after 10 moves, the configuration matches answer B: two upside down cups and one right side up.
