Important: Items may be created as Features to include passages, files, audio and video. Note that Items with Questions should not be used as a resource Item. If you choose an Item with Questions as resource Item, the Question widgets will be removed when displayed in the assessment resource panel. See Figure 3 for more details about the resource panel.
