Final answer:
The hatching (diagonal grey lines) on a map can represent different features such as mountain ranges or areas of conflict; however, it often depends on the map's context. Hatching on conservation maps may denote environmentally sensitive areas.
Step-by-step explanation:
The areas on the map shaded by hatching (diagonal grey lines) typically represent different features depending on the context of the map. However, considering the options provided, none exactly match scenarios where hatching might be used. Hatching might sometimes indicate mountain ranges on physical maps to show elevation, although color shading is more common for this purpose. On political maps, hatching can sometimes denote areas of conflict where boundaries are disputed, as in the case of Crimea and Taiwan where territorial claims are complex and contested. For national parks and agricultural regions, other symbols or colors are commonly used. Additionally, maps that focus on conservation efforts might use hatching patterns to indicate protected or environmentally sensitive areas, which would be most consistent with the example provided of the Inter-Ministry decree map where protected areas are in black, priority biodiversity areas in grey, and sensitive biodiversity sites in light grey.
