Q: Passage: 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. Question: What was the problem with AA gunnery?

A: successfully aiming a shell to burst close to its target's future position

Q: Passage: French infantry were equipped with the breech-loading Chassepot rifle, one of the most modern mass-produced firearms in the world at the time. With a rubber ring seal and a smaller bullet, the Chassepot had a maximum effective range of some 1,500 metres (4,900 ft) with a short reloading time. French tactics emphasised the defensive use of the Chassepot rifle in trench-warfare style fightingthe so-called feu de bataillon. The artillery was equipped with rifled, muzzle-loaded La Hitte guns. The army also possessed a precursor to the machine-gun: the mitrailleuse, which could unleash significant, concentrated firepower but nevertheless lacked range and was comparatively immobile, and thus prone to being easily overrun. The mitrailleuse was mounted on an artillery gun carriage and grouped in batteries in a similar fashion to cannon. Question: On what was the mitrailleuse mounted?

A:
on an artillery gun carriage
