* Read the following passage carefully and answer the questiosn : (Q.No. 076 to 080)

The science of fireworks is technically called 'pyrotechnics' - from the Greek
word 'pyr' meaning fire and 'technics' meaning an art. Pyrotechnics includes not only
fireworks but also a whole range of devices that use similar materials and principles,
from safety matches that we use every day to solid fuel rocket boosters of space shuttle.
The household match is considered a special pyrotechnic device, as all the pyrotechnic
effect - heat, smoke, light, gas and sound are present in it.

Some historians say that 'black powder', the basic material used in fireworks,
was invented in India. Shukranti, written more than two thousand years ago, has
references to weapons similar to guns and projectile weapons. However, the Chinese are
generally considered the pioneers of pyrotechnics. They are said to have developed, black
powered more than one thousand years ago. It took at least two thousand years for the
knowledge to spread to the West, and it was only in 1242 that an English Monk, Roger
Bacon, revealed the formula for "black powder". He considered it such a dangerous
substance that he wrote of it in a code language.

(A) India (B) China

(C) Greek (D) None of the above

077. Roger Bacon was

(A) a Chinese writer (B) an Indian historian
