A is False. Sugar crops were just like any other crop that required hard work from slaves. It was so hard that they often chose to get beaten instead of working because they considered it to be worth it. That's why sugar plantation owners started thinking of various ways to get slaves to work that didn't involve physical abuse.
B is True. The sugar produced came from sugar cane which grew easily in the climate where the Portuguese land owners lived. They could grow a lot of it and export it all around the world, from the Americas to Europe and back. That's why they needed many slaves.
C is false. European people traded with Africans as far back as the roman Empire. This was mostly in the north of Africa but the kingdoms in the south like Mali were known worldwide. When people started looking for India around the south of Africa, they established tradings posts along the way.
D should be false. Sugar had to be extremely secure when transported to Europe because it is sugar and we all know how easily it melts in water. If anything happened to it then entire earnings could be lost and this would be detrimental for both consumers and producers.
E is true. Everyone wanted sugar and wanted to control sugar productions. That's why there were many incentives for even those who became free to start their own colonies somewhere in order to produce sugar. Places in the South America never seemed to produce enough.
F is false. Portuguese laborers did not work on plantations. Plantations had workers that were slaves and those who were indentured slaves from all around the world. The workers worked elsewhere and found other jobs or they found their own plantations.
