H08 · Old information, new question
Adult reads the complete small P2 fact card in Useful facts, with their source limits, or uses C15's full fictional longer record instead. Ask “What does this tell us, and what doesn't it tell about today?” No decimals or mean calculation. Notice: source scope versus today's result. Next: use C06 to separate past information from a current forecast and a later observation.
Complete named ordinary first source
All data are invented Pebble Room visitor notes: 5 January in story years One, Two and Three records rain visible during each specified short view; 5 June in those same story years records no rain visible during each specified view. Same named place, viewpoint and story hour. The guide-maker reports rain-line topics with those January visits and cloud-character topics with those June visits. No other dates, amount, species, full local climate, whole season, cause or next-year result is supplied. An adult can read the labels as “same month across three story years”.
Other whole ordinary sources. Later notes require grown-up release.
