All 30 stories are built, and every question was written from the text of the book.
The book numbers three stories in a row as 19, then has one story numbered 20, 21 and 22. The tower follows the book, so it has three floors marked 19 and one marked 20+.
The copy I worked from uses British spelling in places (storey, colour) and calls Story 13 A Giggle Box, a Leaky Tap and a Foghorn. The questions use American spelling and the American title, Leaky Faucet.

Story 5: the book calls Sharie's guest a hobo, and so do the questions.
Story 11: Kathy sings a grim version of London Bridge about the school falling down. The questions do not quote it.
Story 13: Mrs. Jewls reads a sad story in which a young skunk loses his mother.
Story 14: one student suggests a rude tattoo. The questions leave it out.
The third Story 19: Allison and Mark wonder for a moment whether Miss Zarves is the devil. The questions leave that out.
Story 26: Mrs. Jewls says shut up, breaks a yardstick, and threatens a student before she is cured.
Story 28: Mrs. Waloosh calls Ron King of the Gypsies. The questions leave that phrase out.
Several stories depend on the first book, especially the ones about Mrs. Gorf (15 and 24), Rondi (23), and Paul and Leslie (6 and 26).
