It does seem like they are asking the same thing but there is one difference. In (b) it says 'What motivations does <em>Las Casas</em> ascribe to Spanish conquerors and settlers?' While in (c) it says 'How do you think the goals of the Spanish shaped their relations with treatment of native peoples?'
So for question b you are to write about how 'Las Casas' motivated the Spanish Conquerors and Settlers.
For question c you are to write about what you think the goals that the Spanish wanted to achieve had changed and shaped the treatment of the native people.
B) is asking what might motivate las casas the priest to ascribe to spanish conquerers and settlers c) is asking how the goals of of the spanish intertwined with the treatment of the natives
Patent law in the US is the Patent Act. It protects new inventions and establishes the US Patent Office to accept patent applications. Its authority is from the US Constitution which says "Congress shall have power to promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries."
