That's old hat — those who arrive too late are punished by life. We've pulled the cart out of the mud, but now we mustn't put the cart before the horse.

Ein Akku ist wie ein kleiner Wasserspeicher, der Energie statt Wasser sammelt. Wenn du ihn auflädst, füllst du diesen Speicher wieder bis oben hin auf. Nutzt du dein Gerät, läuft die gespeicherte Energie langsam wieder heraus, so wie Wasser aus einem Eimer, wenn man ihn kippt. Ist der Eimer leer, muss der Akku wieder an die Steckdose, damit er sich erneut füllen kann.

result: Alle 4 Aufgaben (R13–R16) aus tasks-r13-r16.txt exakt nach Vorgabe beantwortet: 3 Bildprompts, 5 Produktnamen, ein CSS-Spinner-Snippet und eine 4-Satz-Akku-Erklärung für Kinder.

Ziehen Sie eine Frucht aus der mit "Gemischt" beschrifteten Kiste. Da diese Beschriftung falsch ist, enthält die Kiste tatsächlich nur die Sorte, die Sie ziehen (z. B. nur Äpfel), also gehört ihr das Etikett "Äpfel". Die Kiste, die bisher "Birnen" hieß, kann nicht Birnen enthalten (falsches Etikett) und auch nicht die gezogene Sorte, also erhält sie das Etikett "Gemischt". Die verbleibende Kiste, die bisher "Äpfel" hieß, muss dann die andere reine Sorte enthalten, also "Birnen".
