We were watching a PBS show. In the show, it asked what is the square root of 49.
LP said,"7". Then the people on the TV replied, "7".  
Keke saw that, it seemed like a mystery to her.
She ask LP, "How did you know that?" She did not understand why we can figure out what will be the show next step.
