You just have to understand the personality of my second born to get a hoot out of the question:
Using numerals 1-3, arrange them chronologically.
Apparently we need to hit home a bit better on pronouns so he knows that 'them' in this case is referring to the Stone, Bronze and Iron Ages and not 'numerals'.
Hearing the roar of laughter after he handed in this paper made me definitely aware that he was just trying to get a rise out of his teacher.
This teacher has the capability of withholding peanut butter cookies and therefore gets the last laugh.
