Competitors must meet at least one of the three conditions to qualify for the cross-country championship:

Crossed the finish line either first or second during the qualifiers
Crossed the finish line within 15 minutes during the qualifiers
Finished in the top 5 of the previous year’s championship

Cerci is part of the planning group for this year’s championship.

Cerci: “There were 20 people who finished within the 15-minute timeframe during the qualifiers, so I must plan for 27 people in the championship race.”

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

Some competitors may have met more than one condition, so there should be fewer than 27 people. Cerci hasn’t accounted for the competitors who may drop in on the day, unannounced. There may be a lot more competitors this year due to the event's popularity last year. Some competitors may have met more than one condition, so more than 27 people should be there.

Are you sure you want to leave?
