T3W5 TS Q08 – Selective High School

In the award ceremony, the principal's award was given to anyone who ranked first in a subject or ranked top three overall.

Billy: "Well, since there are eight subjects in our school, at least eight students received the principal's award as students that ranked top three overall can be one of them."

Which one of the following sentences shows the mistake Billy has made?

Some students might rank first in multiple subjects. Students that ranked top three overall could not be the student that ranked first in a subject. There should be at least eleven students that received the principal's award. Ranked first in a subject did not guarantee ranked top three overall.

Are you sure you want to leave?
