 Part I. Write 10 {question_type} exam questions that can be solved analytically, without numerical methods,
         in increasing order of difficulty from easiest to hardest that would test a student's ability on the topic {selected_topic} in {subject}. 
-        The easiest question should be the most basic problem on {selected_topic}. The hardest two questions would be very tricky even for an undergraduate 
-        mathematics major at a top university.
+        The easiest question should still require at least one step beyond direct formula recognitition. The hardest two questions would be very tricky even for an undergraduate 
+        mathematics major at a top university, but still must be analytically solvable.
         Observe the following about {question_type} questions: {problem_type_addition}.
         Note: If you specify a quadrant restriction (e.g. "in the first quadrant") in a problem with calculating area between lines/curves or volume between surfaces, make sure the question is CLEAR about what regions you intend to be included in the solution, by breaking up the question. Examples:
         - NOT CLEAR question: Find the area of the region bounded by the curves y = sin(x), y = cos(x), and x = 7*pi/4 in the first quadrant.
