Question 9

Some people line up. The source says: “There are 3 people standing in front of 3 people, 3 people standing behind 3 people and 3 people standing between 3 people.” How many people are there?

The final source phrase is ambiguous. For this question, count exactly the two disjoint consecutive groups of three described at the front and back, with no extra people; treat the final phrase as an imprecise repeated description, not an additional condition.
