what did the line of demarcation show .....A.the land of the Maya's and the Aztecs ...B.where water from Rivers flow into the Atlantic Ocean or the Pacific Ocean ...C. where Portugal and Spain could settle and trade ...D. where Central America ends and South America begins



Answer :

The land of demarcation was a line approved by the Pope Alexander VI at the treaty of Tordesillas, in which Portugal und Spain "split" the world into two parts: everything  west of the line that was either discovered or about to be discovered would be under Spanish contror; east - Portuguese control. (c).

(the line was moved a bit to the west in 1494, which resulted in brazil belonging to Portugal- but this was before the official discovery of Brazil: this suggests the Portuguese had knowledge of Brazil earlier than claimed! (1500)
