Practice sets in the style of the Scholar's Challenge, on the 2026 theme. Every answer comes with the reasoning behind it.
These are built the way real Challenge questions are built. The answer is almost never a single fact you either have or don't. It's a connection between two things you already know, and the three wrong options are written to look right to anyone who half-knows the material. Read the explanation even when you got it right, because the reasoning is the part that carries over to the next question.
