Easy

a) Maths rated the BEST - most students gave score 4-5 (you need to imagine the box-plot as histogram or area under the graph to understand this better). English is the second best as they have median value higher than Science. English is not the best because the number of students who like/dislikes the subject is spread out more than maths.

b) Both median and upper quartile is 5 whilst the lower quartile is 4. This means 50% of the students choose score of 4 and 5. From that group more than 50% of them chose score of 5 (or more than 25% overall).
