Ira turned to see what the sharp whistle was all about. It looked like Professor Hadley had enough of the game and had decided to end it. Finally!

Ira wasn't too tired from the game,to say the truth. because the actual; case was, she was the one who got to tag others, but rarely got tagged herself! So nope, she didn't have had a lot of calculations to do!

Then came the questions. Pattern among the calculations? Were there? Other than the fact that they had multiple choices as some other students had already answered? Ira was too busy tagging and being tagged and calculating to notice any pattern! But one thing she knew and she decided to say it. She raised her hand up and answered, "Professor, I just know one thing.. that there are multiple dates for the same number. That is every number repeats itself after.. 8.. no, 9 days. So this is a pattern, right?"
