IOT has had an impact across all fields, be it industries, government, small or large businesses and even for Personal Consumption.
What is IOT (Internet of things) you might ask? It’s been a growing topic of conversation for some time now. Put in the simplest term it means anything that has an on and off button and is connected to the internet for receiving, analyzing, storing or sending data. This could mean anything, from the watch that you wear to airplanes that can be controlled from a remote location. According to the analyst firm Gartner, by the year 2020, we’ll have over 26 billion connected devices. That could mean people to people, people connected to things and things connected to things. The new rule of the future is going to be “Anything that can be connected will be connected”. Take for example that when you set an alarm to wake up and that alarm goes off it not only wakes you up but also brews your coffee, sets the right temperature of water for your bath, puts on the television to bring you the latest updates from around the globe and all this before you even put a foot out of your bed. This is all done by simply getting the network of interconnected things/devices that have embedded sensors, network connectivity, software and necessary electronics that collect and exchange data. To show how far we have come with technology and connectivity, we have smartwatches such as Fitbit, Garmin to name a few that have changed the way we look at time. We have one device that not only tells us the time but also tracks the number of steps, calories and heart rate. This watch is actually connected to our phone so with just one turn of the wrist, one can tell who is calling or what messages have been received without having to dig through pockets or handbags. IOT is making its presence felt in health care as well. Doctors can now remotely monitor and communicate with their patients and health care providers can benefit from this. Whether data comes from foetal monitors, electrocardiograms, temperature monitors or blood glucose levels, tracking this information is vital for some patients. Many of this requires to follow up interaction with healthcare professionals. With smarter devices that deliver more valuable data, it can reduce the need for direct patient-physician interaction. Take for instance in the sporting field, minute chips are being attached to balls and bats which will transmit information of how fast the ball is travelling and a batsman’s moves, the time, the angles, the pressure on the bat at different positions, data of the muscle stretch if he’s hit a six so on and so forth. Formula one cars are also being fitted with these sensors which relay information on the minute moves being made by the driver. Chips are also being put into wearable devices of sportsmen to detect suboptimal action of any body parts to show signs of stress or strain which will help in the early detection of injuries and take preventive measures. IOT has had an impact across all fields, be it industries, government, small or large business and even for personal consumption. IBM, Google, Intel, Microsoft, and Cisco are some of the top players in the IOT spectrum. With billions of devices connected security becomes a big issue. How can people make sure that their data is safe and secure? This is one of the major concerns in the IOT that becomes a hot topic. Another issue is with all these billions of devices sharing data companies will be faced with the problem of how to store, track, analyse and make vast sense of the information being generated. Companies are monitoring the network segment to identify anomalous traffic and to take action if necessary. Now that we have a fair understanding of IOT let’s see what impact it’s had on the education sector. The only constant in our lives is change and learning. From the get-go, we learn, be it to the walk, talk or run. We adapt to the changing times and constantly learn from them. Education or learning as we know it in the broader sense is the most important of all and the one that decides which way we handle those changes to impact us and the world. Today’s world is fast-paced and to keep up with this we need an infusion of speed with learning. From the classroom assignments, lectures, blackboards, and chalk we have come a long way to what is now known as e-learning (electronic learning) or m-learning (mobile learning). With the GenNext it is imperative to provide the right kind of education. The rise of technology and IOT allows schools to improve the safety of their campuses, keep track of resources and enhance access to information. It ensures data quality being the top priority but also facilitates the development of content allowing teachers to use this technology to create smart lesson plans and ensuring the reach of this content to any corner of the world.
To conclude, IOT has an impact on:

The World Trade Organisation (WTO) was created in the early 1990s as a component of the Uruguay Round negotiation. However, it could have been negotiated as part of the Tokyo Round of the 1970s, since negotiation was an attempt at a ‘constitutional reform’ of the General Agreement on Tariffs and Trade (GATT). Or it could have been put off to the future, as the US government wanted. What factors led to the creation of the WTO in the early 1990s?One factor was the pattern of multilateral bargaining that developed late in the Uruguay Round. Like all complex international agreements, the WTO was a product of a series of tradeoffs between principal actors and groups. For the United States, which did not want a new organization, the disputed settlement part of the WTO package achieved its longstanding goal of a more effective and more legal dispute settlement system. For the Europeans, who by the 1990s had come to view GATT dispute settlement less in political terms add more as a regime of legal obligations, the WTO package was acceptable as a means to discipline the resort to unilateral measures by the United States. Countries like Canada and other middle and smaller trading partners were attracted by the expansion of a rulebased system and by the symbolic value of a trade organization, both of which inherently support the weak against the strong. The developing countries were attracted due to the provisions banning unilateral measures. Finally, and perhaps most important, many countries at the Uruguay Round came to put a higher priority on the export gains than on the import losses that the negotiation would produce, and they came to associate the WTO and a rulebased system with those gains. This reasoning – replicated in many countries – was contained in U. S. Ambassador Kantor’s defense of the WTO, and it announced to a recognition that international trade and its benefits cannot be enjoyed unless trading nations accept the discipline of a negotiated rulebased environment.A second factor in the creation of the WTO was pressure from lawyers and the legal process. The dispute settlement system of the WTO was seen as a victory of legalists but the matter went deeper than that. The GATT, and the WTO, are contract organizations based on rules, and it is inevitable that an organization creating a further rule will, in turn, be influenced by legal process. Robert Hudee has written of the‘momentum of legal development’, but what is this precisely? Legal development can be defined as promotion of the technical legal values of consistency, clarity (or certainty) and effectiveness; these are values that those responsible for administering any legal system will seek to maximize. As it played out in the WTO, consistency meant integrating under one roof a whole lot of separate agreements signed under GATT auspices; clarity meant removing ambiguities about the powers of contracting parties to make certain decisions or to undertake waivers; and effectiveness meant eliminating exceptions arising out of grandfatherrights and resolving defects in dispute settlement procedures and institutional provisions. Concern for these values is inherent in any rulebased system of cooperation since without these value rules would be meaningless in the first place, therefore, create their own incentive for fulfillment.The moment of legal development has occurred in other institutions besides the GATT, most notably in the European Union (EU). Over the past two decades, the European Court of Justice (ECJ) has consistently rendered decisions that have expanded incrementally the EU’sinternal market, in which the doctrine of ‘mutual recognition’ handed down in Cassis de Dijon case in 1979 was a key turning point. The court is now widely recognized as a major player in European integration, even though arguably such a strong role was not originally envisaged in the Treaty of Rome, which initiated the current European Union. One means the Court used to expand integration was the ‘teleological method of interpretation’, whereby the actions of member states were evaluated against ‘the accomplishment of the most elementary goals set forth in the Preamble to the (Rome) treaty. The teleological method represents an effort to keep current policies consistent with stated goals, and it is analogous to the effort in GATT to keep contracting party trade practices consistent with slated rules. In both cases, legal concerns and procedures are an independent force for further cooperation.In the large part, the WTO was an exercise in consolidation. In the context of a trade negotiation that created a nearrevolutionary expansion of international trade rules, the formation of the WTO was a deeply conservative act needed to ensure that the benefits of the new rules would not be lost. The WTO was all about institutional structure and dispute settlement: these are the concerns of conservatives and not revolutionaries, that is why lawyers and legalists took the lead on these issues. The WTO codified the GATT institutional practice that had developed by custom over three decades, and it incorporated a new dispute settlement system that was necessary to keep both old and new rules from becoming a sham. Both the international structure and the dispute settlement system were necessary to preserve and enhance the integrity of the multilateral trade regime that had been built incrementally from the 1940s to the 1990s.
What would be the closest reason why WTO was not formed in 1970's?
Read the given passage carefully and answer the questions given after the passage:
1. Often, we passionately pursue matters that in the future appear to be contradictory to our real intention or nature; and triumph is followed by remorse or regret. There are numerous examples of such a trend in the annals of history and contemporary life.
2. Alfred Nobel was the son of Immanuel Nobel, an inventor who experimented extensively with explosives. Alfred too carried out research and experiments with a large range of chemicals; he found new methods to blast rocks for the construction of roads and bridges; he was engaged in the development of technology and different weapons; his life revolved around rockets and cannons and gun powder. The ingenuity of the scientist brought him enough wealth to buy the Bofors armament plant in Sweden.
3. Paradoxically, Nobel's life was a busy one yet he was lonely; and as he grew older, he began suffering from guilt of having invented the dynamite that was being used for destructive purposes. He set aside a huge part of his wealth to institute Nobel Prizes. Besides honouring men and women for their extraordinary achievements in physics, chemistry, medicine and literature, he wished to honour people who worked for the promotion of peace.
4. It's strange that the very man whose name was closely connected with explosives and inventions that helped in waging wars willed a large part of his earnings for the people who work for the promotion of peace and the benefit of mankind. The Nobel Peace Prize is intended for a person who has accomplished the best work for fraternity among nations, for abolition or reduction of war and for promotion of peace.
5. Another example that comes to one's mind is that of Albert Einstein. In 1939, fearing that the Nazis would win the race to build the world's first atomic bomb, Einstein urged President Franklin D Roosevelt to launch an American programme on nuclear research. The matter was considered and a project called the Manhattan Project was initiated. The project involved intense nuclear research the construction of the world's first atomic bomb. All this while, Einstein had the impression that the bomb would be used to protect the world from the Nazis. But in 1945, when Hiroshima was bombed to end World War II, Einstein was deeply grieved and he regretted his endorsement of the need for nuclear research.
6. He also stated that had he known that the Germans would be unsuccessful in making the atomic bomb, he would have probably never recommended making one. In 1947, Einstein began working for the cause of disarmament. But, Einstein's name still continues to be linked with the bomb.
Man's fluctuating thoughts, changing opinions, varying opportunities keep the mind in a state of flux. Hence, the paradox of life: it's certain that nothing is certain in life.

As the climate in the Middle East changed, beginning around 7000 B.C. conditions emerged that were conducive to a more complex and advanced form of civilization in both Egypt and Mesopotamia. The process began when the swampy valleys of the Nile in Egypt and of the Tigris and Euphrates Rivers in Mesopotamia became drier, producing riverine lands that were both habitable and fertile, attracting settlers armed with the newly developed techniques of agriculture. This migration was further encouraged by the gradual transformation of the once-hospitable grasslands of these regions into deserts. The human population became increasingly concentrated into pockets of settlement scattered along the banks of the great rivers.
These rivers profoundly shaped the way of life along their banks. In Mesopotamia, the management of water in conditions of unpredictable drought, flood and storm became the central economic and social challenge. Villagers began early to build simple earthworks, dikes, canals, and ditches to control the waters and reduce the opposing dangers of drought during the dry season (usually the spring) and flooding at harvest time.
Such efforts required a degree of cooperation among large number of people, that had not previously existed. The individual village, containing only a dozen or so houses and families, was economically vulnerable; but when several villages, probably under the direction of a council of elders, learned to share their human resources in the building of a coordinated network of water-control systems, the safety, stability, and prosperity of all improved. In this new cooperation, the seeds of the great Mesopotamian civilizations were being sown.
The technological and mathematical inventions, too, were stimulated by life along rivers. Such devices as the noria (a primitive waterwheel) and the Archimedean screw (a device for raising water from the low riverbanks to the high ground where it was needed), two forerunners of many more varied and complex machines, were first developed here for use in irrigation systems. Similarly, the earliest methods of measurement and computation and the first developments in geometry were stimulated by the need to keep track of land holdings and boundaries in fields that were periodically inundated.
The rivers served as high roads of the earliest commerce. Traders used boats made of bundles of rushes to transport grains, fruits, nuts, fibers, and textiles from one village to another, transforming the rivers into the central spines of nascent commercial kingdoms. Trade expanded surprisingly widely; we have evidence suggesting that, even before the establishment of the first Egyptian dynasty, goods were being exchanged between villagers in Egypt and others as far away as Iran.
Similar developments were occurring at much the same time along the great river valleys in other parts of the world - for example, along the Indus in India and the Hwang Ho in China. The history of early civilization has been shaped to a remarkable degree by the relation of humans and rivers.
According to the passage, the increasing aridity of formally fertile grasslands in Egypt and Mesopotamia caused the settlement patterns in those regions to become
Paragraph: China’s rising power is based on its remarkable economic success. Shanghai’s overall economy is currently growing at around 13% per year, thus doubling in size every five or six years. Everywhere there are start-ups, innovations, and young entrepreneurs hungry for profits. In a series of high-level meetings between Chinese and African officials, the advice that the African leaders received from the Chinese was sound and more practical than they typically get from the World Bank. Chinese officials stress the crucial role of public investments, especially in agriculture and infrastructure, to lay the basis for private sector-led growth. In a hungry and poor rural economy, as China was in the 1970s and as most of Africa is today, a key starting point is to raise farm productivity. Farmers need the benefits of fertilizer, irrigation and high-yield seeds, all of which were a core part of China’s economical take off. Two other equally critical investments are also needed: roads and electricity, without which there cannot be a modern economy. Farmers might be able to increase their output, but it won’t be able to reach the cities, and the cities won’t be able to provide the countryside with inputs. The government has taken pains to ensure that electricity grids and transportation networks reach every village in China. China is prepared to help Africa in substantial ways in agriculture, roads, power, health and education. And that is not an empty boast. Chinese leaders are prepared to share new high yield rice varieties, with their African counterparts and, all over Africa, China is financing and constructing basic infrastructure.
This illustrates what is wrong with the World Bank. The World Bank has often forgotten the most basic lessons of development, preferring to lecture the poor and force them to privatize basic infrastructure, which is untenable, rather than to help the poor to invest in infrastructure and other crucial sectors. The Banks’ failure began in the early 1980s when under the ideological sway of the American President and British Prime Minister tried to get Africa and other poor regions to cut back or close down government investments and services. For 25 years, the bank tries to get governments out of agriculture, leaving impoverished peasants to fend for themselves. The result has been a disaster in Africa, with farm productivity stagnant for decades. The bank also pushed for privatization of national health systems, water utilities, and road and power networks, and has grossly underfinanced these critical sectors. This extreme free-market ideology, also called “structural adjustment”, went against the practical lessons of development successes in China and the rest of Asia. Practical development strategy recognizes that public investments - in agriculture, health, education, and infrastructure- are necessary complements to private investments. The World Bank has instead wrongly seen such vital public investments as an enemy of private sector development. Whenever the banks’ ideology failed, it has blamed the poor for corruption, mismanagement, or lack of initiative. Instead of focusing its attention on helping the poorest countries to improve their infrastructure, there has been a crusade against corruption. The good news is that African governments are getting the message on how to spur economic growth and are getting crucial help from China and other partners that are less wedded to extreme free-market ideology than the world Bank. They have declared their intention to invest in infrastructure, agriculture modernistation, public health, and education. It is clear the Bank can regain its relevance only if it becomes practical once again, by returning its focus to financing public investments in priority sectors. If that happens, the Bank can still do justice to the bold vision of a world of shared prosperity that prompted its creation after World War II.

There is a fairly universal sentiment that the use of nuclear weapons is clearly contrary to morality and that its production probably so, does not go far enough. These activities are not only opposed to morality but also to the law if the legal objection can be added to the moral, the argument against the use and the manufacture of these weapons will considerably be reinforced. Now the time is ripe to evaluate the responsibility of scientists who knowingly use their expertise for the construction of such weapons, which has deleterious effect on mankind.
To this must be added the fact that more than 50 percent of the skilled scientific manpower in the world is now engaged in the armaments industry. How appropriate it is that all this valuable skill should be devoted to the manufacture of weapons of death in a world of poverty is a question that must touch the scientific conscience.
A meeting of biologists on the Long-Term Worldwide Biological consequences of nuclear war added frightening dimension to those forecasts. Its report suggested that the long biological effects resulting from climatic changes may at least be as serious as the immediate ones. Sub-freezing temperatures, low light levels, and high doses of ionizing and ultraviolet radiation extending for many months after a large-scale nuclear war could destroy the biological support system of civilization, at least in the Northern Hemisphere. Productivity in natural and agricultural ecosystems could be severely restricted for a year or more. Post war survivors would face starvation as well as freezing conditions in the dark and be exposed to near lethal doses of radiation. If, as now seems possible, the Southern Hemisphere were affected also, global disruption of the biosphere could ensue. In any event, there would be severe consequences, even in the areas not affected directly, because of the interdependence of the world economy. In either case the extinction of a large fraction of the earth’s animals, plants and microorganism seem possible.
The population size of Homo sapiens conceivably could be reduced to prehistoric levels or below, and extinction of the human species itself cannot be excluded.
Which of the following is one of the consequences of nuclear war?

It is an old saying that knowledge is power. Education is an instrument that imparts knowledge and therefore, indirectly controls power. Therefore, ever since the dawn of our civilisation, persons in power have always tried to supervise or control education. It has been the handmaid of the ruling class. During the Christian era, the ecclesiastics controlled the institution of education and diffused among the people the gospel of the Bible and religious teachings. These gospels and teachings were no other than a philosophy for the maintenance of the existing society. It taught the poor man to be meek and to earn his bread with the sweat of his brow, while the priests and the landlords lived in luxury and fought duels for the slightest offence. During the Renaissance, education passed more from the clutches of the priest into the hands of the prince. In other words, it became more secular. Under the control of the monarch, education began to devise and preach the infallibility of its masters, the monarch or king. It also invented and supported fantastic theories like “The Divine right Theory” and that the king can do no wrong, etc. With the advent of the industrial revolution, education took a different turn and had to please the new masters. It now no longer remained the privilege of the baron class, but was thrown open to the new rich merchant class of the society. The philosophy which was in vogue during this period was that of “Laissez Faire” restricting the function of the state to a mere keeping of laws and order while on the other hand, in practice the law of the jungle prevailed in the form of free competition and the survival of the fittest.
What does the policy of “Laissez Faire” stand for?

A large number of branches of banks have been set-up in the villages. The main purpose of setting up these banks is to develop the habit of saving among the villagers and also to give loans to farmers for boosting production in one way or the other. So, banks had been concentrated in the bigger cities and Indian villagers had no faith in them.
The new banks also intend to re-channel bank credit -from the big industries to the small sectors. With the intention of promoting rural banking, regional rural banks were established. These aligned the local field with rural problems. These banks are not to replace the other credit-giving bodies but to supplement them.
The Steering Committee of the Regional Rural Banks considered some structural changes. First of all, they gave thought to the staffing spectrum, then to effective coordination among banks rural cooperatives and commercial and the possibility of bringing credit within the access to weaker sections. They wanted to recruit staff for the rural banks at lower salaries. But, this type of discrimination would have been unfruitful. So, it was given up.
A problem with regard to the rural banks is the creditworthiness of the poor. The Indian farmers are so poor that they cannot pay back their loans. The rural Indian surveys make it quite clear that practically rural farmers have no credit worthiness. Their socio-economic mobility is almost zero. That is why banks fear that their credit will never be paid back.
Another difficulty for the rural banks is that loans cannot be processed so easily. Processing loans also entails heavy expenditure. This was also going to affect their financial position. Still, the establishment of the rural banks was decided because the social advantages were more important than the commercial consideration.
Rural banks definitely encourage savings. No doubt the villagers do not have to pay income tax and they get many other concessions, yet their saving is not significant. Despite all the hurdles, the rural banking system will boost up the economy of villages and thereby the economy of the country.
Which of the following is/are the purpose of setting up banks in rural areas?
I. Replacing other credit-giving bodies.
II. Giving loans to farmers.
III. Increasing the amount of savings of villagers.

Although the legal systems of England and the United States are superficially similar, they differ profoundly in their approaches to and uses of legal reasons: substantive reasons are more common than formal reasons in the United States, whereas in England the reverse is true. This distinction reflects a difference in the visions of law that prevails in the two countries. In England, the law has traditionally been viewed as a system of rules; the United States favours a vision of law as an outward expression of a community's sense of right and justice.
Substantive reasons, as applied to law, are based on moral, economic, political and other considerations. These reasons are found both "in the law" and ''outside the law" so to speak. Substantive reasons inform the content of a large part of the law: constitutions, statutes, contracts, verdicts and the like. Consider, for example, a statute providing that "no vehicles shall be taken into public parks." Suppose that no specific rationales or purposes were explicitly written into the statute, but that it was clear (from its legislative history) that the substantive purpose of the statute was to ensure quiet and safety in the park. Now suppose that a veterans' group mounts a World War II jeep (in running order but without a battery) as a war memorial on a concrete slab in the park, and charges are brought against its members. Most judges in the United States would find the defendants not guilty because what they did had no adverse effect on the park's quiet and safety. Formal reasons are different in that they frequently prevent substantive reasons from coming into play, even when substantive reasons are explicitly incorporated into the law at hand. For example, when a document fails to comply with stipulated requirements, the court may render the document legally ineffective. A Will requiring written witness may be declared null and void and, therefore, unenforceable for the formal reason that the requirement was not observed. Once the legal rule - that a Will is invalid for lack of proper witnessing - has been clearly established, and the legality of the rule is not in question, application of that rule precludes from consideration substantive arguments in favour of Will's validity or enforcement. Legal scholars in England and the United States have long bemused themselves with extreme examples of formal and substantive reasoning. On the one hand, formal reasoning in England has led to wooden interpretations of statutes and an unwillingness to develop the common law through judicial activism. On the other hand, freewheeling substantive reasoning in the United States has resulted in statutory interpretations so liberal that the texts of some statutes have been ignored.
It can be inferred from the passage that English judges would like to find the veterans' group discussed in the second paragraph guilty of violating the statute because

One of South America's mysteries is Easter Island. Easter Island, also called Rapa Nui and Isla de Pascua, 3600 Ion (2,237mi) west of Chile, is a volcanic island with an interesting and partly unknown history. The island was named by the Dutch explorer Jacob Roggeveen because he encountered it on Easter Sunday 1722. He was the first European to find the island. The official name of the island, Isla de Pascua, means Easter Island in Spanish. This island is famous because of the approximately 887 huge statues which were found there. The statues consist of heads and complete torsos, the largest of which weight 84 tons! These monuments, called moai, were carved out of compressed volcanic ash, called tuff, which was found at a quarry ar a place called Rano Raraku. Statues are still being found. Some of the monuments were left only half-carved. Nobody knows why Rano Raraku was abandoned. It is thought that the statues were carved by the ancestors of the modern Polynesian inhabitants. But, the purpose of the statues and the reason they have abandoned remain mysteries.
Why the quarry, where the compressed volcanic ash was found, abandoned?
