A. 13 including both section 3 and section 15.

12) SORTED From 3 (TO) 15 which means 15 was sorted unless younger generations came up with different word meaning...

B:12 It was from 3 to 15. The librarian did not sort section 15.

13 is the right answer. Section 3 to 15, means he dotted sll except section 1&2.
15-2=13.

Pick a number between 1 and 10. That means you include 1 and 10.

Zero
The librarian had ZERO books to sort because they were all removed due to pornographic content.
