Problem: History of India:

The Hephthalites (or Ephthalites), also known as the White Huns, were a nomadic confederation in Central Asia during the late antiquity period. The White Huns established themselves in modern-day Afghanistan by the first half of the 5th century. Led by the Hun military leader Toramana, they overran the northern region of Pakistan and North India. Toramana's son Mihirakula, a Saivite Hindu, moved up to near Pataliputra to the east and Gwalior to the central India. Hiuen Tsiang narrates Mihirakula's merciless persecution of Buddhists and destruction of monasteries, though the description is disputed as far as the authenticity is concerned. The Huns were defeated by the Indian kings Yasodharman of Malwa and Narasimhagupta in the 6th century. Some of them were driven out of India and others were assimilated in the Indian society.

Where did the White Huns roam?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
There are many styles of mandolin, but four are common, the Neapolitan or round-backed mandolin, the carved-top mandolin and the flat-backed mandolin. The round-back has a deep bottom, constructed of strips of wood, glued together into a bowl. The carved-top or arch-top mandolin has a much shallower, arched back, and an arched topboth carved out of wood. The flat-backed mandolin uses thin sheets of wood for the body, braced on the inside for strength in a similar manner to a guitar. Each style of instrument has its own sound quality and is associated with particular forms of music. Neapolitan mandolins feature prominently in European classical music and traditional music. Carved-top instruments are common in American folk music and bluegrass music. Flat-backed instruments are commonly used in Irish, British and Brazilian folk music. Some modern Brazilian instruments feature an extra fifth course tuned a fifth lower than the standard fourth course.

Question: Two assumptions underpinned the British approach to HAA fire; first, aimed fire was the primary method and this was enabled by predicting gun data from visually tracking the target and having its height. Second, that the target would maintain a steady course, speed and height. This HAA was to engage targets up to 24,000 feet. Mechanical, as opposed to igniferous, time fuses were required because the speed of powder burning varied with height so fuse length was not a simple function of time of flight. Automated fire ensured a constant rate of fire that made it easier to predict where each shell should be individually aimed.
Is there an answer to this question: What kind of fuses were needed?

Answer: Mechanical
