How the crowd plays it
The crowd's reflex here is "Granite" — correct, instant, and worth a Plankton 10. The second reflex, "Marble", belongs to the Too Clever tier: it sounds like a deep cut and lands like a cliché, because every confident player reaches for it in the same second.
Swim past the school and the ladder thins out fast: "Diorite" earns a Deep Cut 85, the mark of a player who reads second pages. The trench floor of this prompt is "Gabbro" — one banked answer, 100 points, no company.
Playing this prompt backwards
When this question surfaces in a dive, your 25 seconds are best spent in reverse: first, name the Plankton answer silently and let it go; second, refuse the Too Clever answer unless the clock is dying; third, search your second page — the runner-up, the older one, the one from the smaller place. In science, that means remembering that work the problem backwards, the way real science often happens: start from the phenomenon and reverse-engineer the name. The mirror rewards reasoning, not just recall.
