The correct answer to this open question is the following.
The new transportation technologies changed economic activity in the period circa 1200 to 1450 in that this industry moved from basic means of transportation such as animals and primitive chariots that limited the transportation of people and goods, to more advanced means such as new navigation vessels that allowed European kingdoms to explore new maritime routes through reaching the Indies and West African coasts, as well as the discovery of the Americas. In this last case, the Kings of Spain, Ferdinand of Aragón and Isabelle of Castille, sponsored Portuguese navigator Christopher Columbus to find a new route to the Indies. Everybody knows the story. Columbus ended up landing in the Americas on October 12, 1492.
