[Q]: Who were the Spanish monarchs that financed Christopher Columbus?, Context: The 1469 marriage of Isabella I of Castile and Ferdinand II of Aragon and the 1479 death of John II of Aragon led to the creation of modern-day Spain. In 1492, Granada was captured from the Moors, thereby completing the Reconquista. Portugal had during the 15th century – particularly under Henry the Navigator – gradually explored the coast of Africa, and in 1498, Vasco da Gama found the sea route to India. The Spanish monarchs met the Portuguese challenge by financing the expedition of Christopher Columbus to find a western sea route to India, leading to the discovery of the Americas in 1492.
[A]: Isabella I of Castile and Ferdinand II of Aragon


[Q]: how complicated were the catechisms that he gave out?, Context: Luther devised the catechism as a method of imparting the basics of Christianity to the congregations. In 1529, he wrote the Large Catechism, a manual for pastors and teachers, as well as a synopsis, the Small Catechism, to be memorised by the people themselves. The catechisms provided easy-to-understand instructional and devotional material on the Ten Commandments, the Apostles' Creed, the Lord's Prayer, baptism, and the Lord's Supper. Luther incorporated questions and answers in the catechism so that the basics of Christian faith would not just be learned by rote, "the way monkeys do it", but understood.
[A]:
easy-to-understand
