Final answer:
In a supervisory control task, the location of information is known and the information on display is unknown.
Step-by-step explanation:
In a supervisory control task, the location of information is known and the information on display is unknown. This means that the person in control knows where to find the information they need, but they may not necessarily know the specific information that will be displayed. An example of this is a supervisor who has access to a database of employee records and can search for specific information, but is not able to see all the information at once on the display.
