In one breath you guys are asserting that you would not believe me if
I said there are people who know that Christ was born on Christmas Day,
while here you are asserting that anyone would find "a Latin" as
acceptable answer to ""Is it Cicero or Caesar who is the author ..."
I don't believe YOU on this one.  I would accept "Tully" since as you say
"Tully" = "Cicero".  But "A Latin" != "Cicero".  It would be a valid answer
to another question, but not this one.

At Christmas time, I have to be a master of giving evasive answers to
inquisitive kids, but both they and I know when I am making a joke
rather than answering.

As for "du" - it is supposed to be mathematical equality.
"1" != "an integer" in mathematics.
