Do You Determine What's In The Market?

I was hanging out at a mall one time, and was approached by a very persistent young lass asking if I'd like to help her with a market research. How could I say no to someone so sweet and persistent. She was only doing her job, I was thinking, besides there was no buying involved. I was asked to watch a series of adverts and answered some simple questions of which there was no right or wrong answer. Now, that was easy. It only took about twenty minutes.
