Compare these to reading comprehension tests on the SAT. Many of those questions ask “why did the author write x?” And all answers are valid insights to the whole piece, but only one is derived from X. It has to be learned to read questions literally imo. It’s not intuitive that questions are as dumb as they are. You must explicitly silence intuition, outside knowledge, social norms towards more impressive seeming insights, awareness of the bigger idea, etc.
