Article: During the High Middle Ages, which began after 1000, the population of Europe increased greatly as technological and agricultural innovations allowed trade to flourish and the Medieval Warm Period climate change allowed crop yields to increase. Manorialism, the organisation of peasants into villages that owed rent and labour services to the nobles, and feudalism, the political structure whereby knights and lower-status nobles owed military service to their overlords in return for the right to rent from lands and manors, were two of the ways society was organised in the High Middle Ages. The Crusades, first preached in 1095, were military attempts by Western European Christians to regain control of the Holy Land from the Muslims. Kings became the heads of centralised nation states, reducing crime and violence but making the ideal of a unified Christendom more distant. Intellectual life was marked by scholasticism, a philosophy that emphasised joining faith to reason, and by the founding of universities. The theology of Thomas Aquinas, the paintings of Giotto, the poetry of Dante and Chaucer, the travels of Marco Polo, and the architecture of Gothic cathedrals such as Chartres are among the outstanding achievements toward the end of this period, and into the Late Middle Ages.

Question: What event led to larger crop yields in the High Middle Ages?
Ans: the Medieval Warm Period


Article: In British English, the word 'asphalt' is used to refer to a mixture of mineral aggregate and asphalt/bitumen (also called tarmac in common parlance). When bitumen is mixed with clay it is usually called asphaltum. The earlier word 'asphaltum' is now archaic and not commonly used.[citation needed] In American English, 'asphalt' is equivalent to the British 'bitumen'. However, 'asphalt' is also commonly used as a shortened form of 'asphalt concrete' (therefore equivalent to the British 'asphalt' or 'tarmac'). In Australian English, bitumen is often used as the generic term for road surfaces. In Canadian English, the word bitumen is used to refer to the vast Canadian deposits of extremely heavy crude oil, while asphalt is used for the oil refinery product used to pave roads and manufacture roof shingles and various waterproofing products. Diluted bitumen (diluted with naphtha to make it flow in pipelines) is known as dilbit in the Canadian petroleum industry, while bitumen "upgraded" to synthetic crude oil is known as syncrude and syncrude blended with bitumen as synbit. Bitumen is still the preferred geological term for naturally occurring deposits of the solid or semi-solid form of petroleum. Bituminous rock is a form of sandstone impregnated with bitumen. The tar sands of Alberta, Canada are a similar material.

Question: What is the geological term for asphalt?
Ans: Bitumen


Article: Marshall Field & Company originated in 1852. It was the premier department store on the main shopping street in the Midwest, State Street in Chicago. Upscale shoppers came by train from throughout the region, patronizing nearby hotels. It grew to become a major chain before converting to the Macy's nameplate on 9 September 2006. Marshall Field's Served as a model for other departments stores in that it had exceptional customer service. Field's also brought with it the now famous Frango mints brand that became so closely identified with Marshall Field's and Chicago from the now defunct Frederick & Nelson Department store. Marshall Field's also had the firsts, among many innovations by Marshall Field's. Field's had the first European buying office, which was located in Manchester, England, and the first bridal registry. The company was the first to introduce the concept of the personal shopper, and that service was provided without charge in every Field's store, until the chain's last days under the Marshall Field's name. It was the first store to offer revolving credit and the first department store to use escalators. Marshall Field's book department in the State Street store was legendary; it pioneered the concept of the "book signing." Moreover, every year at Christmas, Marshall Field's downtown store windows were filled with animated displays as part of the downtown shopping district display; the "theme" window displays became famous for their ingenuity and beauty, and visiting the Marshall Field's windows at Christmas became a tradition for Chicagoans and visitors alike, as popular a local practice as visiting the Walnut Room with its equally famous Christmas tree or meeting "under the clock" on State Street.

Question: What free service did Marshall's provide customers until changing their name to Macy's?
