Which of the following items is used to locate places in a world map?

The lines of latitude only
The lines of longitude only
A neighboring area of the location
Intersection of latitude and longitude

The item used to locate places in a world map is the intersection of latitude and longitude. Latitude and longitude are the two sets of lines that crisscross the Earth's surface and form a grid system.

To find a specific location on a world map, you would need both latitude and longitude coordinates, which intersect to form a precise point on the map. Latitude lines run horizontally, while longitude lines run vertically. The intersection of these lines creates a grid of squares known as degrees, minutes, and seconds.

So, the correct answer is:

Intersection of latitude and longitude
