And why should I change my teaching methods to accommodate your lack
of knowledge? Enroll in my classes, and then maybe I'll make
allowances for your particular knowledge gaps.

Your arguments have almost convinced me that I should *remove* the
checkmark symbol from future versions of the problem, precisely so
that I can count off points for people who aren't familiar with the
ordinary vocabulary of the language used around them every day. Such
people need to be punished for not paying enough attention, and should
likely take remedial English courses to improve their vocabulary.

I don't see why it matters. The problem wasn't written in logical
formulas; it was written in English.

Why would you assume that an exam question has errors in it?

No, not "maybe". This is a fact. Look at the sentences. The only
imperatives are "put" and "don't leave".

It's perfectly clear to anyone who knows English syntax and verb
morphology.

The words "check" and "mark" do not occur in the problem.

What do clock noises, arachnids, or mattress casings have to do with
putting checkmarks in boxes?

Since the problem is written in English rather than logical formulas,
they are already aware of the limitations of clarity (it's a
significant topic of discussion in the course).

And what about the one I actually mentioned, "to check off" (not
"check it off")? It's listed under "check" (v.1), definition 16b. It
is not marked "U.S", and one of the given examples is from Charles
Dickens (who is certainly not American).

Again, the problem is written *in English*, not in logical formulas.
The students know this. They know that no human language is perfectly
clear, so they know to interpret English as English.

I still see no reason to leap to the assumption that an exam problem
has an error.

No, it's not. If they chose randomly, then in the long run, roughly
half of them would get the problem wrong. The statistics don't
support the hypothesis that students answer that problem randomly.

Indeed! I catch about 1-2 cheaters per year. Lord knows how many I
don't catch.

Practicality, of course.
Besides, since this particular problem only has two answers, it
doesn't do any good to reword it 50 different ways. Two different
versions is sufficient.

You clearly have not dealt with cheaters. I have. They cheat for a
reason, and most of the time, it's because they're stupid or lazy,
neither of which is going to help them notice that one single word has
been changed in a simple binary choice problem.

But I don't want my students to put arachnids on their exams. Lyme
disease is a serious problem in this part of the country, and I would
prefer not to contract it.

No, they're just generally quite knowledgeable about the vocabulary of
the language used around them on a daily basis.
