Problem: George VI:

Throughout the war, the King and Queen provided morale-boosting visits throughout the United Kingdom, visiting bomb sites, munitions factories, and troops. The King visited military forces abroad in France in December 1939, North Africa and Malta in June 1943, Normandy in June 1944, southern Italy in July 1944, and the Low Countries in October 1944. Their high public profile and apparently indefatigable determination secured their place as symbols of national resistance. At a social function in 1944, Chief of the Imperial General Staff Sir Alan Brooke, revealed that every time he met Field Marshal Bernard Montgomery he thought he was after his job. The King replied: "You should worry, when I meet him, I always think he's after mine!"

What improved when the King and Queen visited different military sites?
---
A: morale

---
A: the average level


Problem: Hard rock:

In the late 1960s, the term heavy metal was used interchangeably with hard rock, but gradually began to be used to describe music played with even more volume and intensity. While hard rock maintained a bluesy rock and roll identity, including some swing in the back beat and riffs that tended to outline chord progressions in their hooks, heavy metal's riffs often functioned as stand-alone melodies and had no swing in them. Heavy metal took on "darker" characteristics after Black Sabbath's breakthrough at the beginning of the 1970s. In the 1980s it developed a number of subgenres, often termed extreme metal, some of which were influenced by hardcore punk, and which further differentiated the two styles. Despite this differentiation, hard rock and heavy metal have existed side by side, with bands frequently standing on the boundary of, or crossing between, the genres.

What did hard rock music change to keep it's identity?
---
A: unanswerable


Problem: Buckingham Palace:

At the centre of this wing is the famous balcony with the Centre Room behind its glass doors. This is a Chinese-style saloon enhanced by Queen Mary, who, working with the designer Sir Charles Allom, created a more "binding" Chinese theme in the late 1920s, although the lacquer doors were brought from Brighton in 1873. Running the length of the piano nobile of the east wing is the great gallery, modestly known as the Principal Corridor, which runs the length of the eastern side of the quadrangle. It has mirrored doors, and mirrored cross walls reflecting porcelain pagodas and other oriental furniture from Brighton. The Chinese Luncheon Room and Yellow Drawing Room are situated at each end of this gallery, with the Centre Room obviously placed in the centre.

The Principle Corridor features which type of doors?
---
A:
mirrored doors
