Can you hear me now

One of the college students we sing with in the choir at church is a communication major. She had to do some sort of test/project where she recorded a child who was between 24 months and 42 months. It just so happens that I have two of those children.
She came with the recording device yesterday and was supposed to record 100 utterances or apparently about an hours worth of time. She chose to record Doug because she thought she could understand him better. However, Andy is my more talkative child. The kid is a running commentary with constant narration of what is going on and you can definitely hear him sorting out the world with his comments and questions.
She spent just under an hour down in the play room. Apparently she had to follow him around some. I suggested that she get him on the subject of trains or monster trucks. I'd love to know what exactly she was supposed to find out and where Doug is at. He is one of those kids that would rather act silly then admit that he doesn't know something.
