How this list was compiled

Written for this site; nothing was copied from another list. Questions and wrong choices are our own. Each explanation restates, in our own sentences, a fact from the English Wikipedia article named and linked beside the question (https://en.wikipedia.org, text under the Creative Commons Attribution-ShareAlike 4.0 license): Rainforest, Amazon rainforest and Tropical rainforest. Each article was read on October 3, 2026, and the passage that states each fact was found in it before the question was kept. Left out on purpose: yearly figures for forest loss and fires, population counts, counts of peoples and anything else a year changes, and every claim about medicines. Levels are our estimate: easy is fair for any table, medium suits people who know the subject, hard will stump most tables. Each question also carries the date its article was read. Licence: own work
