Edward asked:

A professor asked our class, one student at a time, "how do you eat strawberries." The "correct"
answer is "one at a time." What does this mean?

============

Your professor is trying to be clever and to make you think about the meaning of "how". If "how"
refers to the mechanism or actions of eating, then "one at a time" is one possible correct answer... I
guess. Another might be something like, "by chewing and swallowing". He wants you to see that
saying "with cream" or something like that does not tell us "how" we eat strawberries. He (I'm
arbitrarily saying "he") seems to be doing a fairly good job of teaching this, since you're thinking about
it to the extent of asking us.
