1) "Maps are lifeline of navigators" Discuss.​
ozzi

Answer with Explanation:

"Navigators" are people responsible for telling the position of an object in response to its location. It tells which direction the<em> vessel, vehicle or aircraft</em> 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<em> "lifeline."</em> This means that <u>navigators relies on maps</u> in order to know more about the different locations in the area. Without maps, <em>they won't be able to know the correct direction from one point to another.</em> This will also render their navigational skills useless.
