50 free The Lorax trivia questions with answers — literature quiz, new questions added Aug 2026.
45 free The Lorax trivia questions with answers. The Lorax was Dr. Seuss's own favorite of his books, and the one that made him the most enemies. This quiz covers the 1971 story front to back - the Once-ler, the Thneeds, the Bar-ba-loots and Swomee-Swans, the pile of rocks that says UNLESS and the last Truffula seed - then follows it into the 1972 CBS special and the 2012 Illumination film with Danny DeVito, Zac Efron and Taylor Swift. Along the way you get the odd history around it: the Lake Erie line Seuss cut after scientists wrote to him, the logging industry's rebuttal book, the California town that called it unfair, the Kenyan monkey a study says inspired the Lorax's look, and the marketing blitz that put the tree-hugger on an SUV ad. About a third of the questions are easy enough for kids who know the book by heart; the rest are for parents and Seuss completists. Every answer has been checked against Wikipedia and the sources it cites, and each explanation adds one more thing worth knowing.
