Really? I don't see that as being part of the problem. I have no idea whether it's true or not, but suspect it depends largely on socioeconomic status and geography. Even if the children aren't familiar with the term "shepherd", it still comes down to the fact that they do not have enough information to answer the question and still attempt to perform some sort of calculation with no reasoning of why they are doing it.
