Anecdote: in 5th grade science, a test question was "how many moons does Jupiter have?" Two of us answered 12 (that's how many were known back then) The correct answer was "4", which is what the other 20 kids wrote. The explanation was that we'd been studying Galileo, who discovered 4 of the moons. "But", we argued, "that's not what the question asked". In the end, the teacher threw the question out altogether.

Things haven't changed.
