Question: When paying a state visit to Britain, foreign heads of state are usually entertained by the Queen at Buckingham Palace. They are allocated a large suite of rooms known as the Belgian Suite, situated at the foot of the Minister's Staircase, on the ground floor of the north-facing Garden Wing. The rooms of the suite are linked by narrow corridors, one of them is given extra height and perspective by saucer domes designed by Nash in the style of Soane. A second corridor in the suite has Gothic influenced cross over vaulting. The Belgian Rooms themselves were decorated in their present style and named after Prince Albert's uncle Léopold I, first King of the Belgians. In 1936, the suite briefly became the private apartments of the palace when they were occupied by King Edward VIII.
Is there an answer to this question: What floor are the Belgian Suites located?

Answer: ground floor


Question: Predators may increase the biodiversity of communities by preventing a single species from becoming dominant. Such predators are known as keystone species and may have a profound influence on the balance of organisms in a particular ecosystem. Introduction or removal of this predator, or changes in its population density, can have drastic cascading effects on the equilibrium of many other populations in the ecosystem. For example, grazers of a grassland may prevent a single dominant species from taking over.
Is there an answer to this question: What is the driving force for maintaining an equilibrium within an ecosystem?

Answer: biodiversity


Question: However, as stealth technology grows, so does anti-stealth technology. Multiple transmitter radars such as those from bistatic radars and low-frequency radars are said to have the capabilities to detect stealth aircraft. Advanced forms of thermographic cameras such as those that incorporate QWIPs would be able to optically see a Stealth aircraft regardless of the aircraft's RCS. In addition, Side looking radars, High-powered optical satellites, and sky-scanning, high-aperture, high sensitivity radars such as radio telescopes, would all be able to narrow down the location of a stealth aircraft under certain parameters. The newest SAM's have a claimed ability to be able to detect and engage stealth targets, with the most notable being the S-400, which is claimed to be able to detect a target with a 0.05 meter squared RCS from 90 km away.
Is there an answer to this question: What is the most notable SAM that can detect a stealth target?

Answer: the S-400


Question: Given the wide range of styles in classical music, from Medieval plainchant sung by monks to Classical and Romantic symphonies for orchestra from the 1700s and 1800s to avant-garde atonal compositions for solo piano from the 1900s, it is difficult to list characteristics that can be attributed to all works of that type. However, there are characteristics that classical music contains that few or no other genres of music contain, such as the use of a printed score and the performance of very complex instrumental works (e.g., the fugue). As well, although the symphony did not exist through the entire classical music period, from the mid-1700s to the 2000s the symphony ensemble—and the works written for it—have become a defining feature of classical music.
Is there an answer to this question: What did not exist through the entire classical music period?

Answer:
the symphony
