Radio 4 Woman's Hour was getting all steamed up this morning about the social rights and wrongs of tutoring children during the school holidays. "Socially divisive", "giving the posh kids an extra leg up they don't need", "impossible demands placed on young shoulders", etc etc. According to some amongst us, children turn into vegetables during those precious few weeks of summer, and need to be kept nose to grindstone lest they forget how to spell, punctuate, do times tables and stand still in the lunch queue.

The latter I felt able to 'do': it was a syllogism , and its third part didn't follow from its first two, a logical fallacy. The maths question niggled at me, I felt dumb, because I knew it must be a trap, but I literally couldn't think how to solve i...
