Decide first, then press Next. Look for the words that say what the numbers are.
Room 12's poster with its bar graph unlabelled and no source line. Then the labelled version: the graph's title, the word Students up the side and the names under the bars ringed, then the source line, Room 12 class survey, Sept 2026, 20 students. The last step shows Mai's yard-vote poster with an empty source line.
