What are the instructions given on the map regarding natural zones?

The instructions ask to color the natural zones on the continents with different colors, noting that they are almost symmetrically located in both the Northern and Southern hemispheres. It also instructs to draw borders, color, and label the names of repeating natural zones, specifically mentioning Eurasia. For Eurasia, two similar natural zones are to be colored grey in the northern regions and orange in the southern regions, with their names to be written in.
