B) Recent advances in transportation have made it significantly easier to travel between the two land masses.
C) Recent archaeological evidence suggests that Europeans and Asians descended from a single people.
D) Commercial leaders hope to reduce trade barriers between Europe and Asia by redefining the continent as a single land mass.
