The correct answer is Renaissance
The period of the Renaissance, or Italian Renaissance, passed in Europe between the 14th and 16th centuries. It can be said that it was a transitional period between the Middle Ages and the Modern Age, which was marked by important changes in socio-cultural thinking, reflected in the economy, politics and religion. Jacob Burckhardt, in his book "The Culture of the Renaissance in Italy", written in 1867, clearly defines the term "Renaissance", as we understand it today. It is a period of "discovering the world and man". The return to the paradigms of Classical Antiquity, which brought humanism and naturalism as ideal, were the main guiding threads of an entire period of empirical and scientific flourishing of an era.
Option 'B' = changes in climate, had the greatest impact on pre-historic man.
Changes on the weather forced men to move periodically or cyclically, usually returning to their original location at various times. When they moved to colder climates, they would make clothing out of animal skins, to protect themselves. When the nomads learned how to plant, they didn't need to search for other places anymore.
More than anything, the Spanish were seeking wealth.
Christopher Columbus himself thought that he had reached India: he wanted the wealth from the trade with Indians.
In the beginning, the Spanish hoped for Gold and Silver, later also for other products that could be made cheaper in the New World.
In short: the Spanish were not interested in Mexico but in what the ships could bring from Mexico (again, mostly gold).
Some, very few Spaniards, who settled in the New World were too unhappy in Europe and hoped for a better life.
