A practice set presents one source set with multiple linked decisions. Two checkmarks on your scratch map show which tabs were useful earlier, but the current stem has a new claim. The mapped tabs are A: Tutoring Scholarship Allocation Metrics with applications, awards, attendance, and score gains by campus; B: Tutoring Scholarship Allocation Scope Rules with the caveat that impact comparison uses award recipients with baseline and follow-up scores; C: Tutoring Scholarship Allocation Notes with the principal note. The prior item focused on which campus had the most applications; this item asks whether Campus South had the highest matched-recipient score gain. Which strategy best avoids a carryover error?
