What did the treaty of tordesillas do for portugal? a. it allowed portugal to claim brazil. b. it allowed portugal to claim north africa. c. it allowed portugal to claim all of north america. d. it allowed portugal to claim all of south america.

The Treaty of Tordesillas, in essence, divided trading and colonizing rights for all newly discovered lands of the world located between Portugal and Castile (later applied between the Spanish Crown and Portugal) to the exclusion of other European nations. So the only choice that would work here is A. It allowed Portugal to claim Brazil... Which you can see is true today because the Language that Brazil speaks today is nonother than Portuguese.
