And agnostics and atheists seem to get better results.
And on the short version you can take yourself, this agnostic/atheist got 100%, aided by two things.
One, a lucky guess on the last question and two, well, try this:
When does the Jewish Sabbath begin?
Possible answers are Friday, Saturday or Sunday.
The correct answer is “by whose calendar”?
For the Jewish Sabbath is indeed the Saturday: but in the Jewish calendar which day is which is not defined by when is midnight or noon (both quite difficult things to ascertain with accuracy without watches, although sundials will do for one of them). Rather, as would be logical in a pastoral/nomadic society (when many of these rules were first set), by nightfall or dawn, rather more easily observed phenomena.
As it happens, Jewish tradition chose nightfall.
So, the precise answer to the beginning of the Sabbath is the nightfall before Saturday using our standard western calendar, that is, Friday night.
But in the Jewish calendar the Sabbath starts at the beginning of the day after Friday: that’s why they’re celebrating it on what “we” call Friday night because to them it is already the Sabbath, Saturday.
So we’ve a question that (OK, but only by being pedantic, I admit), in this quiz, changes answer dependent upon whether you are Jewish or not.
BTW, no, I’ll not tell you what the quiz thinks is the right answer. Work it out for yourselves.
