प्र:Directions: Read the passage given below and answer the questions that follow by choosing the correct/most appropriate options:
Coffee was first discovered in Eastern Africa in an area we know today as Ethiopia. A popular legend refers to a goat herder by the name of Kaldi, who observed his goats acting unusually friskily after eating berries from a bush. Curious about this phenomenon, Kaldi tried eating the berries himself. He found that these berries gave him _______ energy. The news of this energy-loaded fruit quickly moved throughout the region. Coffee berries were transported from Ethiopia to the Arabian Peninsula and were first cultivated in what today is the country of Yemen. Coffee remained a secret in Arabia before spreading to Turkey and then to the European continent by means of Venetian trade merchants.
Coffee was first eaten as food though later people in Arabia would make a drink out of boiling the beans for its narcotic effects and medicinal value. Coffee for a time was known as Arabian wine to Muslims who were banned from alcohol by Islam. It was not until after coffee had been eaten as a food product, a wine, and a medicine that it was discovered, probably by complete accident in Turkey, that by roasting the beans a delicious drink could be made. The roasted beans were first crushed and then boiled in water, creating an unrefined version of the beverage we enjoy today. The first coffee houses were opened in Europe in the 17th Century and in 1675, the Viennese established the habit of refining the brew by filtering out the grounds, sweetening it, and adding a dash of milk. If you were to explore the planet for coffee, you would find about 60 species of coffee plants growing wild in Africa, Malaysia, and other regions. But only about ten of them are actually cultivated. Of these ten, two species are responsible for almost all the coffee produced in the world: Coffea Arabica and Coffea Canephora (usually known as Robusta). Because of ecological differences existing among the various coffee-producing countries, both types have undergone many mutations and now exist in many subspecies.
Coffee plants need special conditions to give a satisfactory crop. The climate needs to be hot-wet or hot temperate, between the Tropic of Cancer and the Tropic of Capricorn, with frequent rains and temperatures varying from 15 to 25 Degrees C. The soil should be deep, hard, permeable, and well irrigated, with well-drained subsoil. The best lands are the hilly ones or just-tilled woods. The perfect altitude is between 600 and 1200 meters, though some varieties thrive at 2000-2200 meters. Cultivation aimed at protecting the plants at every stage of growth is needed. Sowing should be in sheltered nurseries from which, after about six months, the seedlings should be moved to plantations in the rainy season where they are usually alternated with other plants to shield them from wind and excessive sunlight.
According to the passage, how did coffee first make its way from Ethiopia to the Arabian Peninsula?
