A lot of the questions and answers are a matter of opinion, I think.
Tradition is no longer the standard when it comes to weddings.
But that's the point. The quiz is about tradition -
not practice.
Tradition
by definition is not a matter of opinion - it's a matter of history, religion, region, and ethnicity, etc.
What traditions you decide to adopt or discard at your own wedding would be a matter of opinion.
You have to take into account the majority culture where the quiz is being originated. That is: United States, Northeast, English, Christian.
Thus, if you apply Jewish tradition to this quiz you will get at least one question wrong. Similar issues will pop up with other world cultures and religions.
There is one question that may have a valid argument either way, and the quiz takes the most commonly accepted practice. However, few people would ever notice the difference.
The quiz is intended to poke fun at the ineptness of the "typical male" when it comes to their interest or comfort level with all those "little" wedding details. I'm surprised the average score is only 15 among DJs - must be because we're mostly men.
It would be interesting to see how the women do. Maybe I could get some "Knotties" to give it a try.
