Cloud computing is a method for delivering information technology (IT) services in which resources are (A) (viable) from the Internet through web-based tools and applications, as opposed to a direct connection to a server. Rather than keeping files on a (B) (seamless) hard drive or local storage device, cloud-based storage makes it possible to save them to a remote database. As long as an electronic device has access to the web, it has access to the data and the software programs to run it. The rise of cloud-based software has offered companies from all sectors several benefits, including the ability to use software from any device, either via a native app or a browser. As a result, users can carry their files and settings to other devices in a completely (C) (proprietary) manner. Cloud computing offers big businesses some serious cost-saving potential. Before the cloud became a (D) (tangible) alternative, companies were required to purchase, construct and maintain costly information management technology and infrastructure. Now, instead of investing millions in huge server centres, a firm can use "lite" versions of workstations with (E) (retrieved) fast internet connections. The cloud-like structure allows users to upgrade software more quickly – because software companies can offer their products via the web rather than through more traditional, (F) (lightning) methods involving discs or flash drives.

Find the appropriate word for blank B.

 The Emperor had inherited a peaceful and prosperous kingdom at a young age after the untimely death of his father. A few months later a man arrived at court. He stated that he was from a far off land and had the gift of foresight. He impressed the Emperor with his witty remarks and was appointed a courtier. The Emperor and those at court all enjoyed hearing accounts of his travels. One day the newly appointed minister said, "Your Majesty, you are destined to great things. It is written in the stars. I have learnt the art of fortune telling. Do not be content with your kingdom along. Travel, See the world and conquer. There are many who are oppressed. They will bless you for rescuing them from the tyranny of their rulers." The Emperor was stunned to hear this but he refused to discuss the matter at the time. The courtiers too were astonished to hear this and began debating among themselves. "It is true," they said, "Our Emperor's father was a great warrior and he ruled wisely. Perhaps there is truth in this." So the newly appointed courtier shrewdly planted the idea of waging war against other kingdoms at court. After hearing several repeated arguments in favour of this idea the Emperor finally agreed. He was a young man and a battle seemed to be exciting against a smaller neighbouring kingdom The Emperor knew the ruler was cruel and felt justified in waging war against him. Having the superior army the easily defeated the king. Everyone celebrated. But the campaign did not stop there. With every victory the new minister would urge the Emperor on to the next battle. The soldiers grew tired after over two years at war but did not complain out of respect and loyalty to their ruler. Meanwhile the situation in his kingdom began to deteriorate. With no one to look after the daily administration and to resolve disputes, signs of neglect began to be seen.
The Emperor was no longer bothered if he wars. The new minister who was in charge of these funds kept a large part for himself and grew richer. An old man who had been a minister in the Emperor's father's court grew worried and decided to do something about this situation. A few days later when the Emperor was out riding in the forest he suddenly saw the old man. He greeted him like an old friends and inquired what he was doing there. The man pointed to two owls in the trees. "I am listening to their conversation". What are they saying?" the Emperor asked unbelieving. "They are negotiating the marriage of their children. The first owl wants to know wheter the other will be gifting his daughter fifty villages on her would have to gift her one hundred and fifty as the villages were in ruins and as such were worthless but with the Emperor as ruler there would be many such villages." When the Emperor heard this he realized the error of his ways. He returned home immediately, rewarded the old minister putting him in charge of reconstructing the ruined villages and dismissed the fortune teller from his court.

Pollution befouls the air and poisons water. Pollution induces the release of toxicants into the biosphere which makes the air unsuitable for breathing, harms the quality of water and soil, and causes the emission of substances that may cause damage to humans, plants and animals.
To cater to the needs of an increasing population, agriculture has been intensified through the use of a wide spectrum of fertilizers and pesticides. Diverse industries have been set up to produce chemicals including those that pose a danger to all life forms.

Rapid industrialisation has led to deterioration in the quality of air. Widespread use of coal and fossil fuels in industries and petroleum fuel in motor vehicles has aggravated the air pollution problem. Our atmosphere seems to have become a waste basket into which dust, noxious fumes, toxic gases and other pollutants are callously thrown.

The intensity of air pollution in Indian cities is increasing primarily due to our vintage vehicles and their poor performance. Water pollution, too has increased with the growth of our population and also that of our industries. Water pollution has acquired dangerous dimensions ever since sewage and industrial effluents have started being disposed of into the rivers.

Once considered sacred, the rivers are now turning murky and stink. It is sad that almost three-fourths of our fellow citizens have no choice but to drink filthy water. The severely polluted rivers due to mindless dumping of sewage and industrial wastes are a cause for concern not only to us humans but also to myriads of life forms that exist in water.

On the French and Italian rivier as we can no longer see the sparkling blue waters. The Mediterranean Sea is reported to be turning grey. Rivers and canals pour sewage, detergents and industrial waste into the sea; tankers flush their contents near the river or sea; bottles, rotting garbage and oil slicks are washed into the beaches. The phosphates and nitrates applied to farmlands as inorganic fertilizers, concentrate in lakes and estuaries causing algal blooms due to which wide expanses of water get choked, plants rot, oxygen is used up and fish die.

Since when has water pollution acquired dangerous dimensions?
