You're picking at the difference between the proximate cause and the ultimate cause of the ad looking the way it does. Q: Why does the ad burger patty appear thicker and larger? A: Because we made it *this* way [show process]. Sounds reasonable to me. Perhaps you wanted an answer more like, A: Because we wanted to show off all the ingredients in the best possible light, to encourage you to buy it. It actually takes a few why/because cycles (i.e. root cause analysis) to approach the ultimate cause; for example: A: Because we made it *this* way. Q: Why? A: Because it makes the burger look good and it shows you what's in it. Q: Why? A: Because if the burger looks good and you know what's in it, you'd be more likely to buy it. Q: ??? A: Profit!!! Alas, the original question did not stipulate a particular kind of answer; I think the response, as given, sufficiently answers the question.
