The correct statements that describe why the Renaissance began in the Italian city-states are:
-
Some wealthy merchants used their wealth to support humanist ideas, learning, art, architecture, and literature.
-
The ruins of the Roman Empire still stood in Italy and people there maintained a connection with the learning of the past.
The other two statements are incorrect: Italy did experience the challenges of the Middle Ages, including the plague and wars, and while the popes supported artists, there was not a specific school established by the popes that attracted the finest talent from throughout Europe as a singular institution that would define the Renaissance.
