Which one is the real South America? None.
In this exercise, the distortion of different projections was analyzed using the South America as an example. The transformation process from a 3D world into a 2D surface always will carry some sort of distortion, even though it can be minimized depending of the case.
The choice of the projection will depend mainly of the Area of Interest. In large scales, if the right projection is chosen, the distortion can be minimal. However, when dealing with small scales, this choice has to be seen with more attention. The projection has to fit the project purposes, however, it can often manipulate the reader's world-view - on purpose or not.
