Answer:
This map is biased because it only shows North and South America.
Explanation:
The conventional world maps are maps that are showing the whole world. What exactly will be the focus of the world map depends on the purpose of it, so it can represent the climate zones, major physical features, population density, biomes, borders of the countries, etc. This type of map can come in a rectangular shape, rounded shape, conical shape, depending on the projection used.
The presented map though is biased, and this is based on the fact that it simply doesn't show the whole world but North and South America, with little parts of Africa and Antarctica on the edges, while the rest of the world is absent. Basically, we can say that this map can not represent a world map as it doesn't possess the main trait it should have - the whole world.
