How could two points 35 degrees north of the equator—one in North America and the other in China—be distinguished using map coordinates?

Question

by their elevation

by their map projection

by their longitude

by their latitude

Answer 1

The two points could be distinguished using their longitude coordinates, as the longitude values would be different for the point in North America compared to the point in China. Their latitude values would be the same at 35 degrees north of the equator.
