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.
One of the major concerns of IOT is:

The question in this section is based on what is stated or implied in the passage given below. For the question, choose the option that most accurately and completely answers the question.
The words invention and Innovation are closely linked, but they are not interchangeable. The inventor is a genius who uses his intellect, imagination, time and resources to create something that does not exist. But this invention may or may not be of utility to the masses. It is the enterprising innovator who uses various resources, skills and time to make the invention available for use. The innovator might use the invention as it is, modifies it or even blend two or more inventions to make one marketable product. A great example is that of the iPhone which is a combination of various inventions. If an invention is the result of countless trials and errors, so can be the case with innovation. Not every attempt to make an invention is successful. Not every innovation sees the light of the day. Benjamin Franklin had the belief that success doesn‘t come without challenge, mistake, and in a few cases failure.
One of the world‘s most famous innovators, Steve Jobs says, ―Sometimes when you innovate, you make mistakes. It is best to admit them quickly and get on with improving your other innovations.‖ Thus, inventors and innovators have to be intrepid enough to take risks; consider failures as stepping stones and not stumbling blocks. Some inventions are the result of a keen observation or a simple discovery. The inventor of Velcro, also called the zipless zipper, is the Swiss engineer George de Mestral. He was hiking in the woods when he found burrs clinging to his clothes and his dog‘s fur. Back at home, he studied the burrs. He discovered that each burr was a collection of tiny hooks which made it cling on to another object. A few years later, he made and patented the strips of fabric that came to us like Velcro. The world of inventions and innovations is a competitive one. But the race does not end here; it is also prevalent in the case of getting intellectual property rights. There have been inventors who failed to get a single patent while there have been some who managed to amass numerous patents in their lifetime. Thomas Edison had 1,093 patents to his credit! We relate the telephone with Alexander Graham Bell. It is believed that around the same time, Antonio Meucci had also designed the telephone, but due to a lack of resources and various hardships, he could not proceed with the patent of his invention. It is also believed that Elisha Gray had made a design for the telephone and applied for the patent at the U.S. patent office on the same day as Graham Bell did. By sheer chance, Graham‘s lawyer‘s turn to file the papers came first. Hence, Graham was granted the first patent for the telephone. It is not easy, and at times almost impossible, for an inventor to be an innovator too. There are very few like Thomas Edison who graduated from being an incredible inventor to a successful manufacturer and businessman with brilliant marketing skills. While innovations that have helped to enhance the quality of life are laudable, equally laudable are the inventions that laid the foundation of these very innovations.
Velcro can be best described as
Answer the question based on the following information. Indicate which of the statements given with that particular question consistent with the description of unreasonable man in the passage below.
Unreasonableness is a tendency to do socially permissible things at the wrong time. The unreasonable man is the sort of person who comes to confide in you when you are busy. He serenades his beloved when she is ill. He asks a man who has just lost money by paying a bill for a friend to pay a bill for him. He invites a friend to go for a ride just after the friend has finished a long car trip. He is eager to offer services wh1ch are not wanted, but which cannot be politely refused. If he is present at an arbitration, he stirs up dissension between the two parties, who were really anxious to agree. Such is the unreasonable man.
The unreasonable man tends to
The old woman didn’t like the look or sound of the kid. She scowled at her husband. ‘Where did you pick up this kitten from? Why do we need her?’ When the old man told her she was a goat kid, she picked her up and exclaimed in amazement: ‘Yes, she is a goat kid!’
All night, they went over the story of how the kid had come into their hands.
That same night the old lady gave the goat kid that resembled a kitten a nickname: Poonachi. She once had a cat by the same name. In memory of that beloved cat, this goat kid too was named Poonachi. They had acquired her without spending a penny. Now they had to look after her somehow. Her husband had told her a vague story about meeting a demon who looked like Bakasuran and receiving the kid from him as a gift. She wondered if he could have stolen it from a goatherd. Someone might come looking for it tomorrow. Maybe her husband had told her the story only to cover up his crime?
The old woman was not used to lighting lamps at night. The couple ate their evening meal and went to bed when it was still dusk. That night, though, she took a large earthen lamp and filled it with castor oil extracted the year before. There was no cotton for a wick. She tore off a strip from a discarded loincloth of her husband’s and fashioned it into a wick.
She looked at the kid under the lamplight in that shed as though she were seeing her own child after a long time. There was no bald spot or bruise anywhere on her body. The kid was all black. As she stared at the lamp, her wide-open eyes were starkly visible. There was a trace of fatigue on her face. The old woman thought the kid looked haggard because she had not been fed properly. She must be just a couple of days old. A determination that she must somehow raise this kid to adulthood took root in her heart.
She called the old man to come and see the kid. She looked like a black lump glittering in the lamplight in that pitch-black night. He pulled fondly at her flapping ears and said, ‘Aren’t you lucky to come and live here?’
It had been a long time since there was such pleasant chit-chat between the couple. Because of the kid’s sudden entry into their lives, they ended up talking a while about the old days.
[Extracted, with edits and revisions, from Poonachi, or the Story of a Black Goat, by Perumal Murugan, translated by N. Kalyan Raman, Context, 2018.]
What can we infer from the passage about why the old couple talked about the old days that night?

Civilization is basically a vital kind of grouping. Without civilizations, the world as we know it would not be. Civilizations have different qualities than regular groups of people such as nomads. For example, a civilization develops surpluses of things which helps the people be a stable community. These surpluses also create the construction and growth of cities and help develop secure, formal states. The government is also present in civilizations. One very important part of a civilization is an advanced writing method. A civilization can only be complete with all of these factors, or it will just fall apart. Nomads are nowhere close to being a civilization even though sometimes groups of nomads have good technology. The words 'culture' and 'civilization' have been often used synonymously, though they have clearly defined meanings differentiating them. 'Civilization' means the betterment of ways of living, making Nature bend to fulfill the needs of humankind. It includes also organizing societies into politically well-defined groups working collectively for improved conditions of life in matters of food, dress, communication, and so on. Thus a group considers itself as civilized, while others were looked down upon as barbarians. This has led to wars and holocausts, resulting in the mass destruction of human beings. What are the good parts of our civilization? First and foremost there are order and safety. If today I have a quarrel with another man, I do not get beaten merely because I am physically weaker and he can kick me down. I go to law, and the law will decide as fairly as it can between the two of us. Thus in disputes between man and man right has taken the place of might. Moreover, the law protects me from robbery and violence. Nobody may come and break into my house, steal my goods or run off with my children. Of course, there are burglars, but they are very rare, and the law punishes them whenever it catches them. It is difficult for us to realize how much this safety means. Without safety, these higher activities of mankind which make up civilization could not go on. The inventor could not invent, the scientist find out or the artist make beautiful things. Hence, order and safety, although they are not themselves civilization are things without which civilization would be impossible. They are as necessary to our civilization as the air we breathe is to us, and we have grown so used to them that we do not notice them any more than we notice the air. Another great achievement of our civilization is that today civilized men are largely free from the fear of pain. They still fall ill, but illness is no longer the terrible thing it used to be... Not only do men and women enjoy better health; they live longer than they ever did before, and they have a much better chance of growing up... Thirdly, our civilization is more secure than any that have gone before it. This is because it is much more widely spread... Previous civilizations were specialized and limited, they were like oases in a desert.
The third merit of the present civilization, according to the author, is:

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.
This passage basically explains
Paragraph: A fundamental principle of pharmacology is that all drugs have multiple actions. Actions that are desirable in the treatment of disease are considered therapeutic, while those that are undesirable or pose risks to the patient are called "effects." Adverse drug effects range from the trivial, e.g., nausea or dry mouth, to the serious, e.g., massive gastrointestinal bleeding or thromboembolism; and some drugs can be lethal. Therefore, an effective system for the detection of adverse drug effects is an important component of the health care system of any advanced nation. Much of the research conducted on new drugs aims at identifying the conditions of use that maximize beneficial effects and minimize the risk of adverse effects.
The intent of drug labeling is to reflect this body of knowledge accurately so that physicians can properly prescribe the drug; or, if it is to be sold without prescription so that consumers can properly use the drug.
The current system of drug investigation in the United States has proved very useful and accurate in identifying the common side effects associated with new prescription drugs. By the time a new drug is approved by the Food and Drug Administration, its side effects are usually well described in the package insert for physicians. The investigational process, however, cannot be counted on to detect all adverse effects because of the relatively small number of patients involved in premarketing studies and the relatively short duration of the studies.
Animal toxicology studies are, of course, done prior to marketing in an attempt to identify any potential for toxicity, but negative results do not guarantee the safety of a drug in humans, as evidenced by such well-known examples as the birth deformities due to thalidomide.
This recognition prompted the establishment in many countries of programs to which physicians report adverse drug effects. The United States and other countries also send reports to an international program operated by the World Health Organization. These programs, however, are voluntary reporting programs and are intended to serve a limited goal: alerting a government or private agency to adverse drug effects detected by physicians in the course of practice. Other approaches must be used to confirm suspected drug reactions and to estimate incidence rates. These other approaches include conducting retrospective control studies; for example, the studies associating endometrial cancer with estrogen use, and systematic monitoring of hospitalized patients to determine the incidence of acute common side effects, as typified by the Boston Collaborative Drug Surveillance Program.
Thus, the overall drug surveillance system of the United States is composed of a set of information bases, special studies, and monitoring programs, each contributing in its own way to our knowledge about marketed drugs. The system is decentralized among a number of governmental units and is not administered as a coordinated function. Still, it would be inappropriate at this time to attempt to unite all of the disparate elements into a comprehensive surveillance program. Instead, the challenge is to improve each segment of the system and to take advantage of new computer strategies to improve coordination and communication.

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".
why is the increasing gap between labour productivity in agricultural and non - agricurtural occupations a cause of concern according to Radhakrishnan and Sharma?

MY LOVE OF NATURE, goes right back to my childhood, to the times when I stayed on, my grandparents' farm in Suffolk. My father was in the armed forces, so we were always moving and didn't have a home base for any length of time, but I loved going there. I think it was my grandmother who encouraged me more than anyone: she taught me the names of wild flowers and got me interested in looking at the countryside, so it seemed obvious to go on to do Zoology at University.
I didn't get my first camera until after I'd graduated, when I was due to go diving in Norway and needed a method of recording the sea creatures I would find there. My father didn't know anything about photography, but he bought me an Exacta, which was really quite a good camera for the time, and I went off to take my first pictures of sea anemones and starfish. I became keen very quickly, and learned how to develop and print; obviously I didn't have much money in those days, so I did more black and white photography than colour, but it was all still using the camera very much as a tool to record what I found both by diving and on the shore. I had no ambition at all to be a photographer then, or even for some years afterwards.
Unlike many of the wildlife photographers of the time, I trained as a scientist and therefore my way of expressing myself is very different. I've tried from the beginning to produce pictures that are always biologically correct. There are people who will alter things deliberately: you don't pick up sea creatures from the middle of the shore and take them down to attractive pools at the bottom of the shore without knowing you're doing it. In so doing you're actually falsifying the sort of seaweeds they live on and so on, which may seem unimportant, but it is actually changing the natural surroundings to make them prettier. Unfortunately, many of the people who select pictures are looking for attractive images and, at the end of the day, whether it's truthful or not doesn't really matter to them. It's important to think about the animal first, and there are many occasions when I've not taken a picture because it would have been too disturbing. Nothing is so important that you have to get that shot; of course, there are cases when it would be very sad if you didn't, but it's not the end of the world. There can be a lot of ignorance in people's behavior towards wild animals and it's a problem that more and more people are going to wild places: while some animals may get used to cars, they won't get used to people suddenly rushing up to them. The sheer pressure of people, coupled with the fact that there are increasingly fewer places where no-one else has photographed, means that over the years, life has become much more difficult for the professional wildlife photographer.
Nevertheless, wildlife photographs play a very important part in educating people about what is out there and what needs conserving. Although photography can be an enjoyable pastime, as it is to many people, it is also something that plays a very important part in educating young and old alike. Of the qualities it takes to make a good wildlife photographer, patience is perhaps the most obvious -you just have to be prepared to sit it out. I'm actually more patient now because I write more than ever before, and as long as I've got a bit of paper and a pencil, I don't feel I'm wasting my time. And because I photograph such a wide range of things, even if the main target doesn't appear I can probably find something else to concentrate on instead.
Wildlife photography is important because it can make people realise that

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 isn't the exact number of statues known?

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.
