Source Notes
Q3's extracted source shows four visible Column-A items but answer choices contain five mappings; this inconsistency is preserved and flagged rather than silently repaired.
Q10's Excel function punctuation was normalized to =MID("library",4,2) because the extracted text clearly shows the same function with OCR punctuation damage.
No answer key was present in the source pages, so none has been added.
