Answer with Explanation:
"Navigators" are people responsible for telling the position of an object in response to its location. It tells which direction the vessel, vehicle or aircraft needs to follow. In order to do this, they need to be equipped with maps. Maps will allow them to function, since it is their "lifeline." This means that navigators relies on maps in order to know more about the different locations in the area. Without maps, they won't be able to know the correct direction from one point to another. This will also render their navigational skills useless.
