Contrary to how the Protestant Reformers were often characterized, the concept of a catholic or universal Church was not brushed aside during the Protestant Reformation. On the contrary, the visible unity of the catholic or universal church was seen by the Protestant reformers as an important and essential doctrine of the Reformation. The Magisterial reformers, such as Martin Luther, John Calvin, and Huldrych Zwingli, believed that they were reforming the Roman Catholic Church, which they viewed as having become corrupted. Each of them took very seriously the charges of schism and innovation, denying these charges and maintaining that it was the Roman Catholic Church that had left them. In order to justify their departure from the Roman Catholic Church, Protestants often posited a new argument, saying that there was no real visible Church with divine authority, only a spiritual, invisible, and hidden churchthis notion began in the early days of the Protestant Reformation.
What church did the Reformers claim had left them?
the Roman Catholic Church

In the case of the ring-porous hardwoods there seems to exist a pretty definite relation between the rate of growth of timber and its properties. This may be briefly summed up in the general statement that the more rapid the growth or the wider the rings of growth, the heavier, harder, stronger, and stiffer the wood. This, it must be remembered, applies only to ring-porous woods such as oak, ash, hickory, and others of the same group, and is, of course, subject to some exceptions and limitations.
If the growth rings are wider, was the growth of the tree slower or more rapid?
more rapid

In Iberia, the Christian states, which had been confined to the north-western part of the peninsula, began to push back against the Islamic states in the south, a period known as the Reconquista. By about 1150, the Christian north had coalesced into the five major kingdoms of Leon, Castile, Aragon, Navarre, and Portugal. Southern Iberia remained under control of Islamic states, initially under the Caliphate of Cordoba, which broke up in 1031 into a shifting number of petty states known as taifas, who fought with the Christians until the Almohad Caliphate re-established centralised rule over Southern Iberia in the 1170s. Christian forces advanced again in the early 13th century, culminating in the capture of Seville in 1248.
What Islamic state controlled southern Iberia until 1031?
the Caliphate of Cordoba
