Final answer:
Can a map projection possess more than one class of properties? The answer is 'sometimes.' Map projections may attempt to maintain multiple properties, such as area and shape but they often need to compromise on the accuracy to some extent due to Earth's sphericity.
Step-by-step explanation:
The question pertains to map projections and whether they can have more than one class of properties. The simple answer to the question is d) Sometimes. Map projections are methods of representing the curved surface of the Earth on a flat plane. Different projections have different sets of properties and sometimes these properties can overlap.
For instance, a projection might aim to preserve both angles and area to some extent. However, it's important to note that no projection can preserve all properties perfectly due to the spherical shape of the Earth. Thus, while a projection may attempt to maintain multiple properties, it often does so by compromising the accuracy of both to some degree. This includes properties such as area, shape, direction and distance, which are all subject to distortion in a map projection.
