Read the passage carefully and answer the questions that follow:
The victory of the small Greek democracy of Athens over the mighty Persian Empire was furious because Athens had interceded for the other Greek city-states in revolt against Persian domination. In anger, the king sent an enormous army to defeat Athens. He thought it would take drastic steps to pacify the rebellious part of the empire.
Persia was ruled by one man. In Athens, however, all citiens helped to rule. Emboldenedby this participation, Athenians were prepared to die for their city-state. Perhaps this was the secret of the remarkable victory at the marathon, the Persians tried to fool some Greek city-states by claiming to have come in peace. The frightened city of Delos refused to believe this. Not wanting to abet the conquest of Greece, they fled from their city and did not return until the Persians had left. They were wise, for the president next conquered the city of Eritrea and captured its people.
TinyAthens stood alone against Persia. The Athenian people to their sanctuaries. There they prayed for deliverance. They asked their gods to expedite their victory. The Athenians refurbished their weapons and moved to the plan of Marathon where their little band would meet the Persians. At the last moment, soldiers from Plataea reinforced the Athenian troops.
The Athenian army attacked and Greek citizens fought bravely. The power of the mighty Persians was offset by the love that the Athenians had for their city. Athenians defeated the Persians in both archery and combat. Greek soldiers seized Persian sheepand burned them and the Persians fled in terror. Herodotus, a famous historian, reports that 6400 Persians died, compared to only 192 Athenians.
Their participation _________to the Athenians.

Options:In 1962, a team of scientists produced a special radio station that had a range of fifteen moles. Even though communication was being accomplished in space at a range of more than a million times this distance, the new radio station caused must excitement among scientists. The reason: its power supply was ‘battery ‘made of bacteria. For the first time, practical amounts of electricity were being produced by a form of life and put to use.
‘biocell’, the new power supply had a liquid fuel containing tiny forms of life that changed the fuel directly into electric energy. This was far more than an interesting experiment. The biocell is being developed as producer of electricity for radios, for signals to guide ships, for lighting and for other uses. Thought the working biocell is only a few years old, some scientists feel that it will one day produce power cheaply as is now being done by other methods, and that the biocell will use materials that would otherwise be considered a waste. Early biocells were powered with sugar, but a wide range of fuels can be used. Work is being done using sea water to feed the bacteria.
Electricity from living cells is no new idea. Man experienced the strange ‘shock ‘produced by some fish even before electricity was really discovered. Then in time, there were other discoveries. Benjamin Franklin found that lightning in the sky was electricity. Lulgi Galvani found some electricity in the muscles and nerves of animals. Bust the African catfish produces far more electricity than most other living creatures. And another fish, the electric eel, well named, for it has an even greater electric charge. Research works also discovered that even humns produce small amounts of electricity in their bodies. Our hearts produce a very small amount that can be measured, so do our brains. The biocell is completely new in the field of power production and, as yet, no mass-produced models have begun to replace the older types of batteries. It might be wondered, and then what the excitement is all about.
