Analysis
Teaching ladder Crossclimb Level 13: students solve 5 clues before touching order. Answers: BEET, BELT, BOLT, BOAT, BOOT. Only then drag rungs until each neighbor differs by exactly one letter.
Middle phase answers: "Red root vegetable" = BEET; "Waist accessory" = BELT; "Metal fastener" = BOLT; "Floating vessel" = BOAT; "Footwear" = BOOT.
Ordering phase: the valid middle chain is BEET → BELT → BOLT → BOAT → BOOT. This permutation is the only valid one-letter chain for these answers.
Rule demo: BEST and BEET differ in exactly one slot — S→E at the third letter (BEST → BEET).
Rule demo: BEET and BELT differ in exactly one slot — E→L at the third letter (BEET → BELT).
Rule demo: BELT and BOLT differ in exactly one slot — E→O at the second letter (BELT → BOLT).
Rule demo: BOLT and BOAT differ in exactly one slot — L→A at the third letter (BOLT → BOAT).
Rule demo: BOAT and BOOT differ in exactly one slot — A→O at the third letter (BOAT → BOOT).
Rule demo: BOOT and BOOK differ in exactly one slot — T→K at the fourth letter (BOOT → BOOK).
Lesson complete: BEST → BEET → BELT → BOLT → BOAT → BOOT → BOOK. Remember — middles first, order second, combo last.

Clues → order → combo. Never reorder until all middles are filled.
Walk BEST → BEET → BELT → BOLT → BOAT → BOOT → BOOK and confirm each arrow changes one letter: S→E at the third letter (BEST → BEET); E→L at the third letter (BEET → BELT); E→O at the second letter (BELT → BOLT)…
"What you borrow from a library" describes BEST and BOOK together — not either middle rung.
Solution
This Crossclimb is a 4-letter word ladder from BEST to BOOK. The top and bottom rows share one combo clue: What you borrow from a library. The solution path is BEST → BEET → BELT → BOLT → BOAT → BOOT → BOOK, changing exactly one letter between each rung. Middle clues include Red root vegetable, Waist accessory, and Metal fastener, and others — solve these before reordering. Correct middle order: BEET → BELT → BOLT → BOAT → BOOT.
