(B) Read the following statements and correct the wrong ones:
(1) While describing the location of a place mentioning the meridian is sufficient.
Ans: Wrong:- While describing the location of a place, we need to consider one parallel and one meridian.
(2) For describing the extent of a region, it is necessary to assume the latitude and longitude of the centre of the adjoining region.

Ans: Wrong:- Location of a road can be described with latitude and longitude of a point.
(4) 0° East meridian and 180° East meridian.
Ans: Wrong:- 0° meridian and 180° meridian.
(5) The extent of a road or a river course is described with the help of the latitude of a point in the source and the longitude of a point at the end.
Ans: Wrong:- The extent of a road or a river course is described with the help of the latitude and the longitude of a point in the source and also at the end.
