The success in this context can be measured by the position of the box - and - whisker plot values. The lower quartile of Mr. Roland's class is the same as the upper quartile of Mrs. Cai's class. This indicates that at least 25% of Mr. Roland's class results are as good as or better than 75% of Mrs. Cai's class results, showing greater overall success.

Answer:

Mr. Roland's class was more successful because his class's lower quartile was the same as Mrs. Cai's class's upper quartile.
