Yeah but they also walked in on their parents doing the nasty at one time or another..Technically this is true, but for the purposes of this discussion I would consider accompanying your parents to the grocery store to purchase various fruits, one of which being watermelon, basically the same as doing it for themselves, thus they would have enough life experience to understand the mathematical word problem.
It was a test apparently written in Los Angeles in the 90s. Maybe less racist and more accurate for the location in which it was originally administered
