Living things — science exam questions
Questions from grade-school and middle-school science exams on plants, cells, heredity, adaptation and ecosystems, with a few on how an investigation is set up and read. Each card keeps only the correct answer, so difficulty is mixed: some are plain recall, others take a step of reasoning.

此牌组在导入时经过修改： A subset of the questions was selected and each multiple-choice item was turned into a card: only the text of the correct answer is kept, the distractors and the option letters are removed. Questions that point at material the card does not carry, that describe the answer grid rather than the world — including every bare “Which is…” and every comparative superlative — that are negative, or whose answer does not stand on its own, are all dropped. What survived was read and what read badly was named and removed in the connector source. The deck is built from the questions of a single science domain, recognised by an explicit list of words: a question that touches two domains, or none, goes into no deck at all. Whitespace is normalised and flattened chemical formulas are given their subscripts back (H2O → H₂O); no word is rewritten.
