How this list was compiled: Written for this site by the editors; nothing was copied from another list. Every question, wrong choice and explanation is our own wording. Each answer, and each extra fact in the line under it, was checked on 2026-09-19 against the English Wikipedia article (https://en.wikipedia.org) named and linked beside the question. The article text was fetched through the MediaWiki API on 2026-09-18 or 2026-09-19, and the sentence that states the fact was read before the question was kept. Arithmetic answers were worked out by calculation and checked by a script; their source line names the article that explains the method. Questions were dropped or reworded when the article did not state the fact in plain words (the height of the Hammurabi stele, where the word paper comes from, who founded Alexandria, the length of the Ring of Fire). Left out on purpose: records and rankings that change, populations, living people, and film, TV, brand and league names. No question appears under two grade buttons, and none repeats a question in the site's other trivia question packs as they stood on 2026-09-19. The topics for each grade follow the site's plan and the levels are an editor's judgment; neither is an official curriculum. Licence: own work

How this list was compiled: Written for this site by the editors; nothing was copied from another list. Every question, wrong choice and explanation is our own wording. Each answer, and each extra fact in the line under it, was checked on 2026-09-19 against the English Wikipedia article (https://en.wikipedia.org) named and linked beside the question. The article text was fetched through the MediaWiki API on 2026-09-18 or 2026-09-19, and the sentence that states the fact was read before the question was kept. Arithmetic answers were worked out by calculation and checked by a script; their source line names the article that explains the method. Questions were dropped or reworded when the article did not state the fact in plain words (who was the oldest delegate in 1787, whether federal judges serve for life, who coined the word ecosystem, why energy is lost between the levels of a food chain). Left out on purpose: records and rankings that change, populations, living people, and film, TV, brand and league names. No question appears under two grade buttons, and none repeats a question in the site's other trivia question packs as they stood on 2026-09-19. The topics for each grade follow the site's plan and the levels are an editor's judgment; neither is an official curriculum. Licence: own work
