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.

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.

Direction: The passage given below is followed by a set of question. Choose the most appropriate answer to each question.
Ahmedabad’s Sunday market that sells junk is this 35-year-old artist’s favourite hunting ground. That’s where he picks saw-blades, printer toners, monitors, busted VCDs and hard disks, video players and other castaway gems. Back home, he painstakingly dismantles his treasure of scrap and segregates it into big pieces (the video player's outer case), mid-sized (the insides of a hard disk) and small pieces (innards of a mobile). This is art you can get up, close and personal with. The works grab the viewer’s attention at several levels. Aesthetically, the creations themselves - such as Frivolity which uses feathers and terracotta diyas painted in dark fossil green that give it a strange life - appeal in a live-and-kicking sort of way. Look a little closer and hey, you spot a zipper. Then it’s a journey all your own. Your eyes identify hairpins, spray spouts that hairdressers use, paper clips, thread, computer ribbons and the insides of everything from watches to the sliding metal bits that support drawers. You can almost hear the works whirr. So Hashissh, constructed from paper clips, backpack clips, a shining CD and twirled thread, may invite you to study its water-blue, pinks and green or Nelumbeshwar may beckon, bathed in acrylic pink and grey-black. But once you’re standing in front of a piece, you spot the zips and the hairpins. Then you simply visually dismantle Har’s work and rebuild it all over again. Zoom in, zoom out. It’s great fun. Visualising the colour of his work demands a lot of attention, says Har. “During creation, the material is all differently coloured. So there’s a red switch next to a white panel next to a black clip. It can distract. I don’t sketch, so I have to keep a sharp focus on the final look I am working towards.” As his work evolved, Har discovered laser-cutting on a visit to a factory where he had gone to sand-blast one of his pieces. Hooked by the zingy shapes laser-cutting offered, Har promptly used it to speed up a scooter and lend an unbearable lightness of being to a flighty autorickshaw, his latest works. The NID-trained animation designer’s scrap quest was first inspired by a spider in his bathroom in Chennai when he was a teenager. He used a table-tennis ball (for the head), a bigger plastic ball (for the body) and twisted clothes hangers to form the legs. His next idea was to create a crab, and his mother obligingly brought one home from the market so that he could study and copy it. Winning the first Art Positive fellowship offered by Bajaj Capital Arthouse last year gave Har the confidence to believe that he could make it as an artist or ‘aesthete’ as he likes to call himself.

Direction : The passage given below is followed by a set of questions. Choose the most appropriate answer to each question.
It is a matter of life or death: that’s a concept that gets our attention, whether chuckling over it in a B-grade film, or engrossed by it in an A-grade medical book such as this year’s Pulitzer Prize winner for nonfiction, The Emperor of All Maladies: A Biography of Cancer by Siddhartha Mukherjee. It isn’t hyperbole to call Emperor a literary masterpiece. The Pulitzer citation describes it as, “an elegant inquiry, at once clinical and personal, into the long history of an insidious disease that, despite treatment breakthroughs, still bedevils medical science.” “Elegant” is an apposite description of the New York-based oncologist’s prose, whether he is rephrasing Tolstoy: “Normal cells are identically normal; malignant cells become unhappily malignant in unique ways”; or explaining the book’s provocative title: “This book is a ‘biography’ in the truest sense of the word – an attempt to enter the mind of this immortal illness, to understand its personality, to demystify its behaviour”; or extrapolating, from cancer’s ability to mutate, into the realm of philosophy: “If we, as a species, are the ultimate product of Darwinian selection, then so, too, is this incredible disease that lurks inside us.” Mukherjee weaves together multiple stories about medical advances, doctors and scientists, and the patients who teach us something in the living or dying. Emperor is a historical account of cancer; we understand how cancer rose to prominence as a leading cause of death – as a direct result of human beings living longer now, and more likely to develop cancer. A greater understanding of the disease however comes with the caveat, the more you
know, the more aware you are of how much you don’t know. Tales related to surgery, with its inherent drama, has the edge on our medical reading lists. Some medical books fall into the Self Help category — one of the most successful genres in the publishing world today. While the genre can attract those looking to make a quick buck by peddling to people’s insecurities, there are some useful tomes too. Author Tim Parks in Teach Us to Sit Still shares how reading a famous self-help book, A Headache in the Pelvis helped with his chronic pelvic pain syndrome. Medical books deal with a subject close to our hearts — us, we, ourselves. Perhaps the ones we are most drawn to – thrillers aside – are those that give us a deeper insight into how the mind-body machine works, why we are sick, how we can get better — and, unhappily, sometimes, why we can’t.
According to the author, medical books catch our attention because
Read the passage and answer the question based on it.
Management education gained new academic stature within US Universities and greater respect from outside during the 1960 and 1970s. Some observers attribute the competitive superiority of US corporations to the quality of business education. In1978, a management professor, Herbert A. Simon of Carnegie Mellon University, won the Nobel Prize in economics for his work in decision theory. And the popularity of business education continued to grow, since 1960, the number of master’s degrees awarded annually has grown from under 5000 to over 50,000 in the mid-1980s as the MBA has become known as ‘the passport to the good life’.
By the 1980s, however, US business schools faced critics who charged that learning had little relevance to real business problems. Some went so far as to blame business schools for the decline in US competitiveness.
Amidst the criticisms, four distinct arguments may be discerned. The first is that business schools must be either unnecessary or deleterious because Japan does so well without them. Underlying this argument is the idea that management ability cannot be taught, one is either born with it or must acquire it over years of practical experience. A second argument is that business schools are overly academic and theoretical. They teach quantitative models that have little application to real-world problems. Third, they give inadequate attention to shop floor issues, production processes and to management resources. Finally, it is argued that they encourage undesirable attitudes in students, such as placing value on the short term and ‘bottom line’ targets, while neglecting longer-term development criteria. In summary, some business executives complain that MBA’s are incapable of handling day to day operational decisions, unable to communicate and to motivate people, and unwilling to accept responsibility for following through on implementation plans. We shall analyze these criticisms after having reviewed experiences in other countries.
In contrast to the expansion and development of business education in the United States and more recently in Europe, Japanese business schools graduate no more than two hundred MBA’s each year. The Keio Business School (KBS) was the only graduate school of management in the entire country until the mid-1970s and it still boasts the only two-year master's programme. The absence of business schools in Japan would appear in contradiction with the high priority placed upon learning by its Confucian culture. Confucian colleges taught administrative skills as early as 1630 and Japan wholeheartedly accepted Western learning following the Meiji restoration of 1868 when hundreds of students were dispatched to universities in US, Germany, England, and France to learn the secrets of Western technology and modernization. Moreover, the Japanese educational system is highly developed and intensely competitive and can be credited for raising the literary and mathematical abilities of the Japanese to the highest level in the world.
Until recently, Japan corporations have not been interested in using either local or foreign business schools for the development of their future executives. Their in-company training programs have sought the socialization of newcomers, the younger the better. The training is highly specific and those who receive it have neither the capacity nor the incentive to quit. The prevailing belief, says Imai, ‘is management should be born out of the experience and many years of effort and not learnt from educational institutions.’ A 1960 survey of Japanese senior executives confirmed that a majority (54%) believed that managerial capabilities can be attained only on the job and not in universities.
However, this view seems to be changing: the same survey revealed that even as early as 1960, 37% of senior executives felt that the universities should teach integrated professional management. In the 1980s a combination of increased competitive pressures and greater multi-nationalization of Japanese business are making it difficult for many companies to rely solely on upon internally trained managers. This has led to the rapid growth of local business programmes and greater use of American MBA programmes. In 1982-83, the Japanese comprised the largest single group of foreign students at Wharton, where they not only learnt the latest techniques of financial analysis but also developed worldwide contacts through their classmates and became Americanized, something highly useful in future negotiations. The Japanese, then do not ‘do without’ business schools, as is sometimes contended. But the process of selecting and orienting new graduates, even MBA’s, into corporations is radically different than in the US. Rather than being placed in highly paying staff positions, new Japanese recruits are assigned responsibility for operational and even menial tasks. Success is based upon Japan’s system of highly competitive recruitment and intensive in-company management development, which in turn are grounded in its tradition of universal and rigorous academic education, life-long employment and strong group identification.
The harmony among these traditional elements has made the Japanese industry highly productive and given corporate leadership a long term view. It is true that this has been achieved without much attention to university business education, but extraordinary attention has been devoted to the development of managerial skills, both within the company and through participation in programmes sponsored by the Productivity Center and other similar organizations.

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 behaviour 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.

The work which Gandhiji had taken up was not only regarding the achievement of political freedom but also the establishment of a new social order based on truth and nonviolence, unity and peace, equality and universal brotherhood and maximum freedom for all. This unfinished part of his experiment was perhaps even more difficult to achieve than the achievement of political freedom. In the political struggle, the fight was against a foreign power and all one could do was either join it or wish it success and give it his/her moral support. In establishing a social order on this pattern, there was a strong possibility of a conflict arising between diverse groups and classes of our own people. Experience shows that man values his possessions even more than his life because in the former he sees the means for perpetuation and survival of his descendants even after his body is reduced to ashes. A new order cannot be established without radically changing the mind and attitude of men towards property and, at some stage or the other, the ‘haves’ have to yield place to the ‘have-nots’. We have seen, in our time, attempts to achieve a kind of egalitarian society and the picture of it after it was achieved. But this was done, by and large, through the use of physical force.
In the ultimate analysis it is difficult, if not impossible, to say that the instinct to possess has been rooted out or that it will not reappear in an even worse form under a different guise. It may even be that like a gas kept confined within containers under great pressure, or water held back by a big dam, once the barrier breaks, the reaction will one day sweep back with a violence equal in extent and intensity to what was used to establish and maintain the outward egalitarian form. This enforced egalitarianism contains, in its bosom, the seed of its own destruction.
The root cause of class conflict is possessiveness or the acquisitive instinct. So long as the ideal that is to be achieved is one of securing the maximum material satisfaction, possessiveness is neither suppressed nor eliminated but grows on what it feeds. Nor does it cease to be possessiveness, whether it is confined to only a few or is shared by many.
If egalitarianism is to endure, it has to be based not on the possession of the maximum material goods by a few or by all but on voluntary, enlightened renunciation of those goods which cannot be shared by others or can be enjoyed only at the expense of others. This calls for substitution of material values by purely spiritual ones. The paradise of material satisfaction, which is sometimes equated with progress these days, neither spells peace nor progress. Mahatma Gandhi has shown us how the acquisitive instinct inherent in man can be transmuted by the adoption of the ideal of trusteeship by those who ‘have’ for the benefit of all those who ‘have not’ so that, instead of leading to exploitation and conflict, it would become a means and incentive for the amelioration and progress of society respectively.
Which of the following statements is ’not true’ in the context of the passage?
The question in this section is based on a single passage. The question is to be answered on the basis of what is stated or implied in the passage.
The spread of education in society is at the foundation of success in countries that are latecomers to development. In the quest for development, primary education is absolutely essential because it creates the base. But higher education is just as important for it provides the cutting edge. And universities are the life-blood of higher education. Islands of excellence in professional education, such as Indian Institutes of Technology (IITs) and Indian Institutes of Management (IIMs), are valuable complements but cannot be substituted for universities that provide educational opportunities for people at large.
There can be no doubt that higher education has made a significant contribution to economic development, social progress and political democracy in independent India. It is a source of dynamism for the economy. It has created social opportunities for people, it has fostered the vibrant democracy in our polity. It has provided a beginning for the creation of a knowledge society. But it would be a mistake to focus on its strengths alone. It has weaknesses that are a cause for serious concern. There is, in fact, a quiet crisis in higher education in India that runs deep. It is not yet discernible simply because there are pockets of excellence, an enormous reservoir of talented young people and intense competition in the admissions process. And, in some important spheres, we continue to reap the benefits of what was sown in higher education 50 years ago by the founding fathers of the republic. The reality is that we have miles to go. The proportion of our population, in the age group 18-24, that enters the world of higher education is around 7%, which is only one-half the average for Asia. The opportunities for higher education, in terms of the number of places in universities, are simply not enough in relation to our needs. What is more, the quality of higher education in most of our universities requires substantial improvement? IT is clear that the system of higher education in India faces serious challenges. It needs a systematic overhaul so that we can educated much larger numbers without diluting academic standards. This is imperative because the transformation of economy and society in the 21st century would depend, in significant part, on the spread and the quality of education among our people, particularly in the sphere of higher education. It is only an inclusive society that can provide the foundations for a knowledge society.
The challenges that confront higher education in India are clear. It needs a massive expansion of opportunities for higher education, to 1500 universities nationwide, which would enable India to attain a gross enrolment ration of at least 15% by 2015. It is just as important to raise the average quality of higher education in very sphere. At the same time, it is essential to create institutions that are exemplars of excellence at par with the best in the world. In the pursuit of these objectives, providing people with access to higher education in a socially inclusive manner is imperative. The realization of these objectives, combined with access, would not only develop the skills and capabilities we need for the economy but would also help transform India into a knowledge economy and society.
Should the entire university system in India be modeled on premier institutes, such as IITs and IIMs, providing professional education?
The question in this section is based on the passage. The question is to be answered on the basis of what is stated or implied in the passage.
The Constitution of the United States protects both property rights and freedom of speech. At times these rights conflict. Resolution then requires a determination as to the type of property involved. If the property is private and not open to the general public, the owner may absolutely deny the exercise of the right of free speech thereon. On the other hand, if public land is at issue, the First Amendment protections of expression are applicable. However, the exercise of free speech thereon is not absolute. Rather it is necessary to determine the appropriateness of the forum. This requires that consideration be given to a number of factors including character and normal use of the property, the extent to which it is open to the public, and the number and types of persons who frequent it. If the forum is clearly public or clearly private, the resolution of the greater rights is relatively straight forward.
In the area of quasi-public property, balancing these rights has produced a dilemma. This is the situation when a private owner permits the general public to use his property. When persons seek to use the land for passing out handbills or picketing, how is a conflict between property rights and freedom of expression resolved?
The precept that a private property owner surrenders his rights in proportion to the extent to which he opens up his property to the public is not new. In 1675, Lord Chief Justice Hale wrote that when private property is “affected with a public interest, it ceases to be private.” Throughout the development of AngloAmerican law, the individual has never possessed absolute dominion over property. Land becomes clothed with a public interest when the owner devotes his property to a use in which the public has an interest. In support of this position the chairman of the board of the Wilde Lake Shopping Centre in Columbia, Maryland said:
The only real purpose and justification of any of these centres are to serve the people in the area -not the merchants, not the developers, not the architects. The success or failure of a regional shopping centre will be measured by what it does for the people it seeks to serve.
These doctrines should be applied when accommodation must be made between a shopping centre owner’s private property rights and the public’s right to free expression. It is hoped that when the Court is asked to balance these conflicting rights it will keep in mind what Justice Black said in 1945: “When we balance the constitutional rights of owners of property against those of the people to enjoy (First Amendment) freedom(s) ......... we remain mindful of the fact that the latter occupy a preferred position.”
We can infer from the passage that the author believes that shopping malls in America

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

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.
Which of the following is not included in Thomas Edison's invention?
