QUES: From the 10th to the 13th century, Romanesque architecture had become a pan-European style and manner of construction, affecting buildings in countries as far apart as Ireland, Croatia, Sweden and Sicily. The same wide geographic area was then affected by the development of Gothic architecture, but the acceptance of the Gothic style and methods of construction differed from place to place, as did the expressions of Gothic taste. The proximity of some regions meant that modern country borders do not define divisions of style. On the other hand, some regions such as England and Spain produced defining characteristics rarely seen elsewhere, except where they have been carried by itinerant craftsmen, or the transfer of bishops. Regional differences that are apparent in the great abbey churches and cathedrals of the Romanesque period often become even more apparent in the Gothic.
What is one country in the geographic area that was affected by the development of the Gothic style of architecture?

ANS: Croatia

QUES: The London Underground in England is one of the few networks that uses a four-rail system. The additional rail carries the electrical return that, on third rail and overhead networks, is provided by the running rails. On the London Underground, a top-contact third rail is beside the track, energized at +420v DC, and a top-contact fourth rail is located centrally between the running rails at 210v DC, which combine to provide a traction voltage of 630v DC. London Underground is now upgrading its fourth rail system to 750v DC with a positive conductor rail energised to +500v DC and a negative conductor rail energised to -250v DC. However, many older sections in tunnels are still energised to 630v DC. The same system was used for Milan's earliest underground line, Milan Metro's line 1, whose more recent lines use an overhead catenary or a third rail.
Which system is now upgrading their fifth rail system to 750v DC?

ANS: unanswerable

QUES: By the late 1950s, the motion picture business was again changing. The combination of the studio/theater-chain break-up and the rise of television saw the reduced audience size for cinema productions. The Music Corporation of America (MCA), then predominately a talent agency, had also become a powerful television producer, renting space at Republic Studios for its Revue Productions subsidiary. After a period of complete shutdown, a moribund Universal agreed to sell its 360-acre (1.5 km) studio lot to MCA in 1958, for $11 million, renamed Revue Studios. MCA owned the studio lot, but not Universal Pictures, yet was increasingly influential on Universal's product. The studio lot was upgraded and modernized, while MCA clients like Doris Day, Lana Turner, Cary Grant, and director Alfred Hitchcock were signed to Universal Pictures contracts.
What acronym was the Music Corporation of America known by?

ANS: MCA

QUES: Other sections of society included the nobility, clergy, and townsmen. Nobles, both the titled nobility and simple knights, exploited the manors and the peasants, although they did not own lands outright but were granted rights to the income from a manor or other lands by an overlord through the system of feudalism. During the 11th and 12th centuries, these lands, or fiefs, came to be considered hereditary, and in most areas they were no longer divisible between all the heirs as had been the case in the early medieval period. Instead, most fiefs and lands went to the eldest son.[R] The dominance of the nobility was built upon its control of the land, its military service as heavy cavalry, control of castles, and various immunities from taxes or other impositions.[S] Castles, initially in wood but later in stone, began to be constructed in the 9th and 10th centuries in response to the disorder of the time, and provided protection from invaders as well as allowing lords defence from rivals. Control of castles allowed the nobles to defy kings or other overlords. Nobles were stratified; kings and the highest-ranking nobility controlled large numbers of commoners and large tracts of land, as well as other nobles. Beneath them, lesser nobles had authority over smaller areas of land and fewer people. Knights were the lowest level of nobility; they controlled but did not own land, and had to serve other nobles.[T]
What group constituted the lowest nobility?

ANS:
Knights
