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 our 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.
Technology and IOT have benefited education considerably because it has:

In Mann Joseph's debut novel Serious Men, the protagonist, Ayyan Mani, is a U1, scheming Dalit-Buddhist who almost gets away with passing off his partially deaf son, Adi, as a prodigy, a genius who can recite the first 1,000 prime numbers. The garb of satire-where almost every character cuts a sorry figure-gives the author the licence to offer one' of the most bleak and pessimistic portrayals of urban Dalits. Despite his savage portrayal of Dalit (and Female) character-or perhaps because of it? - Serious Men has won critical appreciation front a cross-section of readers and critics.
At a time when a formidable body of Dalit literature - writing by Dalits about Dalit lives- has created a distinct space for itself, how and why is it that a novel such as serious Men, with its gleefully skewed portrayal of an angry Dalit Man, manages to win such accolades? In American literature and particularly in the case of African-American authors and characters-these issues of representation have been debated for decades. But in India, the sustained refusal to address issues related to caste in every life and the continued and unquestioned predominance of a Brahminical stranglehold over cultural production has led us to a place where the non-Dalit portrayal of Dalits in literature, cinema and art remains the norm.
The journey of modem Dalit literature has been a difficult one. But even though it has not necessarily enjoyed the support of numbers, we must engage with what Dalit are writing not simply for reasons of authenticity, or as a concession to identity politics, but simply because of the aesthetic value of this body of writing, and for the insights, it offers into the human condition. In a society that is still largely unwilling to recognise Dalits as equal, rights-bearing human beings, in a society that is inherently indifferent to the everyday violence against Dalits, in a society unwilling to share social and cultural resources equitably with Dalits unless mandated by law (as seen in the anti-reservation discourse), Dalit literature has the potential to humanise non-Dalits and sensitise them to a world into which they have no insight. But before we can understand what Dalit literature is seeking to accomplish, we need first to come to terms with the stranglehold of non-Dalit representations of Dalits.
Rohinton Miary's ( A Fine Balance), published 15 years ago, chronicles the travails of two Dalit characters uncle Ishvar and nephew Omprakash who migrate to Bombay of the Emergency, Ishvar's father Dukhy belongs to the era of the anti-colonial nationalist movement. During one of Dukhi's visits to the town, he chances upon a meeting of the Indian National Congress, where speakers spread the "Mahatma's message regarding the freedom struggle, the struggle for justice," and wiping out "the disease of untouchability; ravaging us for centuries, denying dignity to our fellow human beings."
Neither in the 1940s, where the novel's past is set nor in the Emergency period of the 1970s when the minds and bodies Ishvar and Omprakash, are savaged by the state do we find any mention of a figure like B.R. Ambedkar or of Dalit movements. In his 'nationalist' understanding of modem Indian history, Mistry seems to have not veered too far from the road charted by predecessors like Mulk Raj Anand and Premchand. Sixty years after Premchand, Mistry's literary imagination seems stuck in the empathy-realism mode, trapping Dalits in abjection. Mistry happily continues the broad stereotype of the Dalit as a passive sufferer, without consciousness of caste politics.
The writer of this passage is critical of Rohinton Mistry's A Fine Balance for the reason that:
In 1954, a Bombay economist named A.D. Shroff began a forum of free Enterprise, whose ideas on economic development were somewhat at odds with those then influentially articulated by the Planning Commission of the Government of India. Shroff complained against the 'indifference, if not discouragement, with which the state treated entrepreneurs.
At the same time as Shroff, but independently of him, a journalist named Philip Spratt was writing a series of essays in favour of free enterprise. Spratt was a Cambridge communist who was sent by the party in the 1920s to the foment revolution in the subcontinent. detected in the act, he spent many years in an Indian jail. The books he read in the prison, and his marriage to an Indian woman afterward, inspired a steady move rightwards. By the 1950s, he was editing a pro-American weekly from Banglore, called mysIndia. there he inveighed against the economic policies of the government of India. These, he said, treated the entrepreneur 'as a criminal who has dared to use his brain independently of the state to create wealth and give employment’. The state’s chief planner, P.C. Mahalanobis had surrounded himself with Western leftists and Soviet academicians, who reinforced his belief in 'rigid control by the government overall activities’. The result, said Spratt, would be `the smothering of free enterprise, a famine of consumer goods, and the tying down of millions of workers to soul-deadening techniques.'
The voices of men like Spratt and Shroff were drowned in the chorus of popular support for a model of heavy industrialization funded and directed by the governments. The 1950s were certainly not propitious times for free marketers in India. But from time to time their ideas were revived. After the rupee was devalued in 1966, there were some moves towards freeing the trade regime and hopes that the licensing system would also be liberalized. However, after Indira Gandhi split the Congress Party in 1969, her government took its `left turn’, nationalizing a fresh range of industries and returning to economic autarky.
Select the statement that could be most plausibly inferred from this passage:
In recent weeks, the writers William Dalrymple and Patrick French, among others, have come before a fusillade of criticism in India, much of it questioning not their facts, not their interpretations, but their foreignness.
"Who gets to write about India?" The Wall Street Journal asked on Wednesday in its own report on this Indian literary feuding. It is a complicated question, not least because to decide who gets to write about India, you would need to decide who gets to decide who gets to write about India. Rather than conjecturing some Committee for the Deciding of the Deciding of Who Gets to Write about India, it might be easier to let writers write what they please and readers read what they wish.
The accusations pouring forth from a section of the Indian commentariat are varied. Some criticism is of a genuine literary nature, fair game, customary, expected. But lately, a good amount of the reproaching has been about identity.
In the case of Mr. Dalrymple, a Briton who lives in New Delhi, it is - in the critics' view - that his writing is an act of re-colonization. In the case of Mr. French, it is that he belongs to a group of foreign writers who use business-class lounges and see some merit in capitalism and therefore do not know the real India, which only the commentariat member in question does.
What is most interesting about these appraisals is that their essential nature makes reading the book superfluous, as one of my Indian reviewers openly admitted. (His review was not about the book but about his refusal to read the book.) The book is not necessary in these cases, for the argument is about who can write about India, not what has been written.
For critics of this persuasion, India surely seems a lonely land. A country with a millennial history of Hindus, Christians, Jews, Muslims and Buddhists living peaceably together; a country of hundreds.of dialects in which so many Indians are linguistic foreigners to each other, and happily, tolerantly so; a country that welcomes foreign seekers (of yoga poses, of spiritual wisdom, of ancestral roots) with open arms; a country where, outside the elite world of South Delhi and South Bombay, I have not heard an Indian ask whether outsiders have a right to write, think or exist on their soil.
But it is not just this deep-in-the-bones pluralism that challenges the who-gets-to write- about India contingent. It is also that at the very heart of India's multifarious changes today is this glimmering idea: that Indians must be rewarded for what they do, not who they are.
Identities you never chose - caste, gender, birth order - are becoming less important determinants of fate. Your deeds - how hard you work, what risks you take - are becoming more important.
It is this idea, which I have found pulsating throughout the Indian layers, that leaves a certain portion of the intelligentsia out of sync with the surrounding country. As Mr. French has observed, there is a tendency in some of these writers to value social mobility only for themselves. When the new economy lifts up the huddled masses, then it becomes tawdry capitalism and rapacious imperialism and soulless globalization.
Fortunately for those without Indian passports, the nativists' vision of India is under demographic siege. The young and the relentless are India's future. They could not think more differently from this literates.
They savor the freedom they are gaining to seek their own level in the society and to find their voice, and they tend to be delighted at the thought that some foreigners do the same in India and love their country as much as they do.
According to the information available in the passage, the writer is of the opinion that:
If religion and community are associated with global violence in the trends of many people, then so are global poverty and inequality. There has, in fact, been an increasing tendency in recent years to justify policies of poverty removal on the ground that this is the surest way to prevent political strife and turmoil. Basing public policy - international as well as domestic- on such an understanding has some evident attractions. Given the public anxiety about wars and disorders in the rich countries in the world, the indirect justification of poverty removal -not for its own sake but for the sake of peace and quiet in the world - provides an argument that appeals to self-interest for helping the needy. It presents an argument for allocating more resources on poverty removal because of its presumed political, rather than moral, relevance.
While the temptation to go in that direction is easy to understand, it is a perilous route to take even for a worthy cause. Part of the difficulty lies in the possibility that if wrong, economic reductionism would not only impair our understanding of the world but would also tend to undermine the declared rationale of the public commitment to remove poverty. This is a particularly serious concern, since poverty and massive inequality are terrible enough in themselves, and deserve priority even if there were no connection whatsoever with violence. Just as virtue is its own reward, poverty is at least its own penalty. This is not to deny that poverty and inequality can - and do - have far-reaching consequences with conflict and strife, but these connections have to be examined and investigated with appropriate care and empirical scrutiny, rather than being casually invoked with unreasoned rapidity in support of a `good cause."
Destitution can, of course, produce provocation for defying established laws and rules. But it need not give people the initiative, courage, and actual ability to do anything very violent. Destitution can be accompanied not only by economic debility but also by political helplessness. A starving wretch can be too frail and too dejected to fight and battle, and even te protest and holler. It is thus not surprising that often enough intense and widespread suffering and misery have been accompanied by unusual peace and silence.
Indeed, many famines have occurred without there being much political rebellion or civil strife or intergroup warfare. For example, the famine years in the 1840s in Ireland were among the most peaceful, and there was little attempt by the hungry masses to intervene even as ship after ship sailed down the river Shannon with rich food. Looking elsewhere, my own childhood memories in Calcutta during the Bengal famine of 1943 include the sight of starving people dying in front of sweetshops with various layers of luscious food displayed behind the glass windows, without a single glass being broken, or law or order being disrupted.
Which of the following statement is least likely to be inferred from the passage:
Paragraph: Many great inventions are initially greeted with ridicule and disbelief. The invention of the airplane was no exception. Although many people who heard about the first powered flight on December 17, 1903 were excited and impressed, others reacted with peals of laughter. The idea of flying an aircraft was repulsive to some people. Such people called Wilbur and Orville Wright, the inventors of the first flying machine, impulsive fools. Negative reactions, however, did not stop the Wrights. Impelled by their desire to succeed, they continued their experiments in aviation.
Orville and Wilbur Wright had always had a compelling interest in aeronautics and mechanics. As young boys they earned money by making and selling kites and mechanical toys. Later, they designed a newspaper-folding machine, built a printing press, and operated a bicycle-repair shop. In 1896, when they read about the death of Otto Lilienthal, the brothers' interest in flight grew into a compulsion.
Lilienthal, a pioneer in hang-gliding, had controlled his gliders by shifting his body in the desired direction. This idea was repellent to the Wright brothers, however, and they searched for more efficient methods to control the balance of airborne vehicles. In 1900 and 1901, the Wrights tested numerous gliders and developed control techniques. The brothers' inability to obtain enough lift power for the gliders almost led them to abandon their efforts.
After further study, the Wright brothers concluded that the published tables of air pressure on curved surfaces must be wrong. They set up a wind tunnel and began a series of experiments with model wings. Because of their efforts, the old tables were repealed in time and replaced by the first reliable figures for air pressure on curved surfaces. This work, in turn, made it possible for the brothers to design a machine that would fly. In 1903 the Wrights built their first airplane, which cost less than $1,000. They even designed and built their own source of propulsion-a lightweight gasoline engine. When they started the engine on December 17, the airplane pulsated wildly before taking off. The plane managed to stay aloft for 12 seconds, however, and it flew 120 feet.
By 1905, the Wrights had perfected the first airplane that could turn, circle, and remain airborne for half an hour at a time. Others had flown in balloons and hang gliders, but the Wright brothers were the first to build a full-size machine that could fly under its own power. As the contributors to one of the most outstanding engineering achievements in history, the Wright brothers are accurately called the fathers of aviation.
The Wrights designed and built their own source of _________.

Rural manual workers comprise the single largest occupational category in India. ln 1991, according to the National Commission on Rural Labour, 60 percent of the workers in rural India were manual workers and they numbered more than 160 million. The changes in the working and living conditions of rural labourers are thus central to changes in the welfare of the rural population and of the country as a whole. The structure and working of rural labour markets in India is complex; as is well known, there is great diversity across regions and across segments of the labour market. This article brings together an interesting body of research that seeks to understand and explain the types of changes that have accrued in the structure of rural labour markets over the last few decades.
The 1980s were characterised by an explosion of the rural labour force, slow employment growth in agriculture and a rise in the share of non-agricultural employment. The decade was also characterized by a growing casualisation of the workforce (for a relative rise in casual employment as opposed to regular employment).
At the same time, it was a period when agricultural wages increased in real terms and when income poverty declined. There was what may be called "the tension between the estimated decline in poverty on the one hand, and the slow growth of agricultural employment and increased casualisation of the labour force on the other. Some of the trends in the development of rural labour over for this period are a source of concern. These include, as Radhakrishnan and Sharma note, the continuous widening of the gap between labour productivity in agricultural and non-agricultural occupations, the burgeoning mass of rural casual workers who have no social security safety net, and the increasing number of women employed at very low wages in agriculture. Another matter for concern, one that emerges from the desegregation of data on rural unemployment by age groups, is that the incidence of unemployment is higher for persons in the age group of 15-29 than for any other age group in others words, unemployment is typically high among new entrants to the workforce.
ln, her review of trends in wages, employment and poverty, Sheila Bhalla shows that the real wages of agricultural labourers stagnated from the time of independence to the mid1970s and then began to rise in all parts of the country. This was also the period in which the incidence of rural poverty began to decline. The rise in wages was not limited to the more prosperous agricultural zones, and Bhalla argues that the movement in real wages was co-related with the increase in the share of non-agricultural employment in total employment. As wages in non-agricultural work are typically higher than wages in agriculture, the expansion of non-farm work could also explain some of the declines in rural poverty. In the 1990s, the improvement in real wages and the decline in poverty were reversed while agricultural employment expanded. Economic development all over the world has been associated with a rise in the share of employment in the secondary and tertiary sectors of the economy and a fail in the share of the agricultural sector. In India, changes in the composition of the rural workforce in the 1990's points to a "structural retrogression"

Read the passage and answer the question following it.
Roger Rosenblatt's book 'Black Fiction', manages to alter the approach taken in many previous studies by making an attempt to apply literary rather than socio-political criteria to subject Rosenblatt points out that criticism of Black writing has very often served as a pretext for an expounding on Black history. The recent work of Addison Gayle's passes judgment on the value of Black fiction by clear political standards, rating each work according to the ideas of Black identity, which it propounds. Though fiction results from political circumstances, its author reacts not in ideological ways to those circumstances and talking about novels and stories primarily as instruments of ideology circumvents much of the enterprise. Affinities and connections are revealed in the works of Black fiction in Rosenblatt's literary analysis; these affinities and connections have been overlooked and ignored by solely political studies.
The writing of acceptable criticism of Black fiction, however, presumes to give satisfactory answers to quite a few questions. The most important of all, is there a sufficient reason, apart from the racial identity of the authors, for the grouping together of Black authors? Secondly, what is the distinction of Black fiction from other modern fiction with which it is largely contemporaneous? In the work, Rosenblatt demonstrates that Black fiction is a distinct body of writing, which has an identifiable, coherent literary tradition. He highlights recurring concerns and designs, which are independent of chronology in Black fiction written over the past eighty years. These concerns and designs are thematic, and they come to form the central fact of the predominant white culture, where the Black characters in the novel are situated irrespective of whether they attempt to conform to that culture or they rebel against it.
Rosenblatt's work does leave certain aesthetic questions open. His thematic analysis allows considerable objectivity; he even clearly states that he does not intend to judge the merit of the various works yet his reluctance seems misplaced, especially since an attempt to appraise might have led to interesting results. For example, certain novels have an appearance of structural diffusion. Is this a defeat, or are the authors working out of, or attempting to forge, a different kind of aesthetic? Apart from this, the style of certain Black novels, like Jean Toomer's Cane, verges on expressionism or surrealism; does this technique provide a counterpoint to the prevalent theme that portrays the fate against which Black heroes are pitted, a theme usually conveyed by more naturalistic modes of expressions?
Irrespective of such omissions, what Rosenblatt talks about in his work makes for an astute and worthwhile study. His book very effectively surveys a variety of novels, highlighting certain fascinating and little-known works like James Weldon Johnson's Autobiography of an Ex-Coloured Man. Black Fiction is tightly constructed, and levelheaded and penetrating criticism is exemplified in its forthright and lucid style.
Rosenblatt's discussion of Black Fiction is
The questions in this section are based on the passage. The questions are to be answered on the basis of what is stated or implied in the passage.
Under very early common law, all felonies were punishable by death. The perpetrators of the felony were hanged whether or not a homicide had been committed during the felony. Later, however, some felonies were declared be non-capital offences. The common law courts, in need of a deterrent to the use of deadly force in the course of these non-capital felonies, developed the "felony-murder" rule. The first formal statement of the rule stated: "Any killing by one in the commission of a felony is guilty of murder." The killing was a murder whether intentional or unintentional, accidental or mistaken. The usual requirement of malice was eliminated and the only criminal intent necessary was the intent to commit the particular underlying felony. All participants in the felony were guilty of a murder-actual killer and non-killer confederates.
Proponents of the rule argued that it was justified because the felony demonstrated a lack of concern for human life by the commission of a violent and dangerous felony and that the crime was murder either because of a conclusive presumption of malice or simply by force of statutory definition.
Opponents of the rule describe it as a highly artificial concept and "an enigma wrapped in a riddle." They are quick to point out that the rule has been abandoned in England where it originated, abolished in India, severely restricted in Canada and a number of other commonwealth countries are unknown in continental Europe and abandoned in Michigan. In reality, the real strength of the opponents' criticism stems from the bizarre and of times unfair results achieved when the felony-murder rule is applied mechanically. Defendants have been convicted under the rule where the killing was purely accidental, or the killing took place after the felony during the later flight from the scene; or a third party killed another (police officer killed a citizen or vice versa; or a victim died of a heart attack 15 -20 minutes after the robbery was over or the person killed was an accomplice in the felony).
Attacks on the rule have come from all directions with basically the same demand -reevaluate and abandon the archaic legal fiction; restrict and limit vicarious criminal liability; prosecute killers for murder, not non-killers; increase punishment for the underlying felony as a real deterrent, and initiate legislative modifications. With the unstable history of the felony -murder rule, including its abandonment by many jurisdictions in this country, the felony -murder rule is dying a slow but certain death.
The author believes that the felony -murder rule is

Thomas Edison was born in 1847 In Milan, Ohio. He was nicknamed 'Al' at an early age. At age 11, Edison moved to Michigan where he spent the remainder of his childhood. Thomas Edition struggled at school but learned to love reading and conducting experiments from his mother who taught him at home. At age 15, Edison became a 'tramp together', sending and rece1vrng messages via Morse code, an electronically-conveyed alphabet using different clicks for each letter. In 1870, Edison moved to New York City and improved the stock ticker. He soon formed his own company that manufactured the new stock tickers. He also began working on the telegraph and invented a version that could send our messages at once. Edison then moved with his family to New Jersey where he started his famous laboratory. In 1877, Edison, with help from 'muckers', individuals from around the world looking to make fortune in America, invented the phonograph. The phonograph was a machine that recorded and played back sounds. In 1878, Edison invented the light bulb as well as the power grid system, which could generate electricity and deliver it to homes through a network of wires. He subsequently started the Edison Electric Light Company in October of 1878. Edison continued to invent or improve products and make significant contributions to X-ray technology, storage batteries and motion pictures (movies). Edison was a prolific inventor, holding 1,093 US patents in his name, as well as many patents in the United Kingdom, France, and Germany.
