No, the Portuguese conquered Malacca in 1511 and controlled the straits until the Dutch took the region from them in the 17th century. So this quiz is wrong. They need to add Malaysia and Indonesia, as the Portuguese controlled territory in those regions as well (not to mention you could argue the Jesuits that oficially founded and controlled Nagasaki for were a part of the Portuguese empire)
There's a cute Portuguese-built colonial town in Uruguay directly across the river from Buenos Aires, appropriately called "Colonia", worth a fast ferry trip from BA.
I know you've put it as an exclusion, but in my opinion Macao (China) should be included in the same way as you have included small parts of other countries (e.g. Uruguay, Malawi). I would have nominated the quiz otherwise.
Portugal did not control India, they were in control of Goa but this is not a type in. If Macao works instead of putting China then Goa should also be the same.
Since the expeditions of Magellan and Da Gama were critical step towards the formation of the Portuguese Empire, I figure this is a good place to plug the map quizzes I made on them. If you're interested, please try them!
