Click the button that contains the type of rock in the picture. Navigate through more rock pictures with the arrows.
The question is presented as a stage background. The answer is a sprite custom. You can create a list of question and answers as long as you like, with the only condition that custom 1 is the answer to background 1, custom 2 is the answer to background 2, and so on. Inside, the code randomly chooses the customes, and insert them in a ListOfQuestions. You navigate the backgrounds until you find the one that explains the type of rock in the custom.
