Problem: Anti-aircraft warfare:

All armies soon deployed AA guns often based on their smaller field pieces, notably the French 75 mm and Russian 76.2 mm, typically simply propped up on some sort of embankment to get the muzzle pointed skyward. The British Army adopted the 13-pounder quickly producing new mountings suitable for AA use, the 13-pdr QF 6 cwt Mk III was issued in 1915. It remained in service throughout the war but 18-pdr guns were lined down to take the 13-pdr shell with a larger cartridge producing the 13-pr QF 9 cwt and these proved much more satisfactory. However, in general, these ad-hoc solutions proved largely useless. With little experience in the role, no means of measuring target, range, height or speed the difficulty of observing their shell bursts relative to the target gunners proved unable to get their fuse setting correct and most rounds burst well below their targets. The exception to this rule was the guns protecting spotting balloons, in which case the altitude could be accurately measured from the length of the cable holding the balloon.

What two guns were propped up against a hillside to get the muzzles pointed up?

A: French 75 mm and Russian 76.2 mm


Problem: On the uneven bars, the gymnast performs a routine on two horizontal bars set at different heights. These bars are made of fiberglass covered in wood laminate, to prevent them from breaking. In the past, bars were made of wood, but the bars were prone to breaking, providing an incentive to switch to newer technologies. The width and height of the bars may be adjusted. In the past, the uneven parallel bars were closer together. They've been moved increasingly further apart, allowing gymnasts to perform swinging, circling, transitional, and release moves, that may pass over, under, and between the two bars. At the Elite level, movements must pass through the handstand. Gymnasts often mount the Uneven Bars using a springboard, or a small mat. Chalk and grips (a leather strip with holes for fingers to protect hands and improve performance) may be used while doing this event. The chalk helps take the moisture out of gymnast's hands to decrease friction and prevent rips (tears to the skin of the hands), dowel grips help gymnasts grip the bar.
How have the bars changed over the years?

Answer: They've been moved increasingly further apart

The Wii version was released alongside the console in North America in November 2006, and in Japan, Europe, and Australia the following month. The GameCube version was released worldwide in December 2006.[b]

Question: Universal could seldom afford its own stable of stars, and often borrowed talent from other studios, or hired freelance actors. In addition to Stewart and Dietrich, Margaret Sullavan, and Bing Crosby were two of the major names that made a couple of pictures for Universal during this period. Some stars came from radio, including Edgar Bergen, W. C. Fields, and the comedy team of Abbott and Costello (Bud Abbott and Lou Costello). Abbott and Costello's military comedy Buck Privates (1941) gave the former burlesque comedians a national and international profile.
Is there an answer to this question: Who starred in the 1914 Buck Privates comedy?

Answer: unanswerable


QUES: The philosophies of Buddhism and Zen, and to a lesser extent Confucianism and Shinto, influenced the samurai culture. Zen meditation became an important teaching due to it offering a process to calm one's mind. The Buddhist concept of reincarnation and rebirth led samurai to abandon torture and needless killing, while some samurai even gave up violence altogether and became Buddhist monks after realizing how fruitless their killings were. Some were killed as they came to terms with these realizations in the battlefield. The most defining role that Confucianism played in samurai philosophy was to stress the importance of the lord-retainer relationship—the loyalty that a samurai was required to show his lord.

What was the contribution of Confucianism to samurai?
What is the answer?
