question:
Passage: The legendary religious zeal of the Normans was exercised in religious wars long before the First Crusade carved out a Norman principality in Antioch. They were major foreign participants in the Reconquista in Iberia. In 1018, Roger de Tosny travelled to the Iberian Peninsula to carve out a state for himself from Moorish lands, but failed. In 1064, during the War of Barbastro, William of Montreuil led the papal army and took a huge booty.
answer:
Where did the Normans carve out a principality before the First Crusade?


question:
Passage: The so-called "Sack of Palermo" is one of the major visible faces of the problem. The term is used to indicate the speculative building practices that have filled the city with poor buildings. The reduced importance of agriculture in the Sicilian economy has led to a massive migration to the cities, especially Palermo, which swelled in size, leading to rapid expansion towards the north. The regulatory plans for expansion was largely ignored in the boom. New parts of town appeared almost out of nowhere, but without parks, schools, public buildings, proper roads and the other amenities that characterise a modern city.
answer:
What is the term for the building boom erected many fine buildings?


question:
Passage: Although Albertus Magnus did much to instill mysticism in the Order of Preachers, it is a concept that reaches back to the Hebrew Bible. In the tradition of Holy Writ, the impossibility of coming face to face with God is a recurring motif, thus the commandment against graven images (Exodus 20.4-5). As time passed, Jewish and early Christian writings presented the idea of 'unknowing,' where God's presence was enveloped in a dark cloud. These images arose out of a confusing mass of ambiguous and ambivalent statements regarding the nature of God and man's relationship to Him.
answer:

What concept does not reach back to the Hebrew Bible?
