Article: The architecture and urbanism of the Classical civilizations such as the Greek and the Roman evolved from civic ideals rather than religious or empirical ones and new building types emerged. Architectural "style" developed in the form of the Classical orders.

Question: What owes its development to the Classical orders?
Ans: Architectural "style"

Article: The work of David Hilbert and Max Planck was crucial to the foundation of modern physics, which Werner Heisenberg and Erwin Schrodinger developed further. They were preceded by such key physicists as Hermann von Helmholtz, Joseph von Fraunhofer, and Gabriel Daniel Fahrenheit, among others. Wilhelm Conrad Rontgen discovered X-rays, an accomplishment that made him the first winner of the Nobel Prize in Physics in 1901. The Walhalla temple for "laudable and distinguished Germans", features a number of scientists, and is located east of Regensburg, in Bavaria.

Question: What two people were important to the creation of modern physics?
Ans: David Hilbert and Max Planck

Article: Victoria's youngest son, Leopold, was affected by the blood-clotting disease haemophilia B and two of her five daughters, Alice and Beatrice, were carriers. Royal haemophiliacs descended from Victoria included her great-grandsons, Tsarevich Alexei of Russia, Alfonso, Prince of Asturias, and Infante Gonzalo of Spain. The presence of the disease in Victoria's descendants, but not in her ancestors, led to modern speculation that her true father was not the Duke of Kent but a haemophiliac. There is no documentary evidence of a haemophiliac in connection with Victoria's mother, and as male carriers always suffer the disease, even if such a man had existed he would have been seriously ill. It is more likely that the mutation arose spontaneously because Victoria's father was over 50 at the time of her conception and haemophilia arises more frequently in the children of older fathers. Spontaneous mutations account for about a third of cases.

Question: How old was Victorias father at the time of her conception?
Ans: over 50

Article: The end result is that the resonant antenna will efficiently feed a signal into the transmission line only when the source signal's frequency is close to that of the design frequency of the antenna, or one of the resonant multiples. This makes resonant antenna designs inherently narrowband, and they are most commonly used with a single target signal. They are particularly common on radar systems, where the same antenna is used for both broadcast and reception, or for radio and television broadcasts, where the antenna is working with a single frequency. They are less commonly used for reception where multiple channels are present, in which case additional modifications are used to increase the bandwidth, or entirely different antenna designs are used.

Question: For use with more than one channel changes are made to increase what property?
Ans:
bandwidth
