Yes. It does not belong in a math test, or at least what we're used seeing in a math test. There are no calculations, or juggling of figures. It has more to do with basic common sense. But it was still a question in an exam, and the kids had to answer it. From the subjects offered at PSLE level, it is more apt to place this question in a math test than any other subject. Definitely not in an English or Mother Tongue Test. There should be a subject called Common Sense, although I don't know how its going to be taught.
