QUES: AA gunnery was a difficult business. The problem was of successfully aiming a shell to burst close to its target's future position, with various factors affecting the shells' predicted trajectory. This was called deflection gun-laying, 'off-set' angles for range and elevation were set on the gunsight and updated as their target moved. In this method when the sights were on the target, the barrel was pointed at the target's future position. Range and height of the target determined fuse length. The difficulties increased as aircraft performance improved.

Where was the barrel pointed when the sights were on a target?
What is the answer?
ANS: the target's future position
QUES: The stemmatic method's final step is emendatio, also sometimes referred to as "conjectural emendation." But in fact, the critic employs conjecture at every step of the process. Some of the method's rules that are designed to reduce the exercise of editorial judgment do not necessarily produce the correct result. For example, where there are more than two witnesses at the same level of the tree, normally the critic will select the dominant reading. However, it may be no more than fortuitous that more witnesses have survived that present a particular reading. A plausible reading that occurs less often may, nevertheless, be the correct one.

Which reading does the critic select when there are only two witnesses at the same tree?
What is the answer?
ANS: unanswerable
QUES: Red, white, and black were the colors of the German Empire from 1870 to 1918, and as such they came to be associated with German nationalism. In the 1920s they were adopted as the colors of the Nazi flag. In Mein Kampf, Hitler explained that they were "revered colors expressive of our homage to the glorious past." The red part of the flag was also chosen to attract attention - Hitler wrote: "the new flag ... should prove effective as a large poster" because "in hundreds of thousands of cases a really striking emblem may be the first cause of awakening interest in a movement." The red also symbolized the social program of the Nazis, aimed at German workers. Several designs by a number of different authors were considered, but the one adopted in the end was Hitler's personal design.

Whose design was the Nazi flag?
What is the answer?
ANS:
Hitler's personal design
