Biology, chapter 4: The cell
A part of the front page about making a quiz from one's own files (source material, e.g. PDFs and Word documents), for teachers, companies and others: an animation of a file of one's own becoming a question in a quiz, in three made-up examples shown in turn. Each has "file", the name of the file as on a computer (a company's strategy, without a year, a chapter of a biology book about the cell, a company's handbook for its employees: write each as a file of that kind would be named in the language), "question", a question a quiz made from that file would ask, written to the person playing, and "answers", its four answers, shown small in narrow buttons, so keep them as short as the English: in the strategy the second is right (keeping the customers it has), in the biology the second (the mitochondrion makes the cell's energy; the others are what other parts of a cell do, wrong answers that show a common misunderstanding), in the handbook the third (one's own manager). Keep the right answers' places
