In order for quizzes to comply with standard guidelines for people with disabilities to work freely with software, an alternate text (Alt Text) must be provided for each element of any computer program. This text will be available for reading by special devices that help people with disabilities work on computers.
You can add alternate text to any media object that accompanies the question text or answer choices. To add an alternate text in Form View mode, select a media object, whether it's an image, video or audio. In the media object Properties menu that appears on the right, enter the Alternate text in the corresponding field.
