Question

question 1
what is the purpose of a map legend?
to explain the symbols and colors used on the map
to show the direction of the north
to list the countries in the map
to delimit the map (or similar option as per ocr)

Explanation:

A map legend's purpose is to explain the symbols and colors (or other marks) used on the map so that the reader can interpret what different elements on the map represent. The first option says "To explain the symbols and colors used on the map" which matches this purpose. The other options: "To show the direction of the wind" is for a wind rose or compass rose, "To list the countries in the map" is not the main purpose of a legend, and "To make the map pretty" is incorrect as legends are functional, not just for aesthetics.

Answer:

A. To explain the symbols and colors used on the map
