The correct answer is:
Both had three motivating factors; however, Columbus achieved spices, God, and glory, whereas da Gama achieved glory and silk.
Explanation: This answer highlights the differences in the primary motivations and achievements of Columbus and Vasco da Gama. Columbus’s motivations centered around the search for new trade routes (including those for spices), the spread of Christianity (as suggested by his reference to converting the indigenous people), and gaining glory through his discoveries. On the other hand, Vasco da Gama was primarily focused on achieving direct trade access to Asia, particularly for spices, which were highly sought after in Europe, thus reflecting a blend of gaining glory and achieving silk trade rather than directly focusing on missionary efforts in the New World.
