The groups that were disqualified then started to leave, and after they all left the attendant said, "Well, now that only the qualified groups are left, let's go towards the lucky test."
He then went towards another building, with all the groups that passed behind him, and when he arrived he said, "Well, come with me. Let's go inside.", and then he entered the building along with all the other groups.
As they entered, they all looked around, and then started talking to each other about what the place.
The attendant then said, "I'm going to explain the rules of the Luck Test. Everyone be quiet please."
Everyone was silent, and the attendant then said, "The lucky test is very simple. One person from each group will be chosen at random, and then everyone will be presented with two choices. The choices will be made in secret, and you will have a minute and a half to make each one. Any questions?"
