The Correct Option is C
Approach Solution - 1
India achieved a significant engineering milestone by converting two WDG3A diesel locomotives into a single fully electric twin-engine locomotive producing a combined 10,000 horsepower. This pioneering work was carried out at the Madhepura Electric Locomotive Factory in Bihar, a facility established in collaboration with the French company Alstom.
The conversion aimed to reduce dependence on diesel, lower operational costs, and minimize environmental impact while increasing hauling capacity for heavy freight. The project also showcased India’s ability to innovate in sustainable transport solutions. Neither the U.S.A, China, nor South Korea had implemented a similar conversion project at the time, making India the first in the world to achieve this feat.

The question asks which country flagged off the world's first Diesel to Electric locomotive twin engine of 10,000 horsepower. Let's check each option.
- U.S.A: No such conversion project of this kind had been carried out in the United States at this time.
- China: China had not undertaken a similar diesel to electric twin engine conversion either.
- India: India converted two WDG3A diesel locomotives into a single fully electric twin engine locomotive producing a combined 10,000 horsepower, built at the Madhepura Electric Locomotive Factory in Bihar, set up with the French company Alstom.
- South Korea: South Korea, too, had no comparable project of this kind at the time.
Since no other country had achieved this specific conversion, India stands as the first to flag off such a locomotive.
Therefore, the correct answer is India.

Approach Solution -3
Since this achievement is defined by a specific engineering conversion, matching each country against whether it actually carried out that conversion answers the question.
- U.S.A: No project converting diesel locomotives into a combined electric twin engine unit of this power rating had been carried out in the United States at this time.
- China: China, too, had not completed a comparable diesel to electric twin engine conversion by this point.
- India: Two WDG3A diesel locomotives were converted into a single fully electric twin engine unit producing a combined 10,000 horsepower, work carried out at the Madhepura Electric Locomotive Factory in Bihar, built in partnership with the French firm Alstom.
- South Korea: South Korea had no equivalent conversion project underway or completed at this time either.
Since only one of the four countries had actually completed this specific conversion, India is confirmed as the answer.
Therefore, the correct answer is India.

- On the evening of the 10th, General Dyer arrived at Amritsar, and the Deputy-Commissioner handed over the civil power to him. He issued a proclamation by word of mouth that no meetings should be held. Two days later, after there had been no sort of riot, nor murder, General Dyer heard that a meeting was to be held at the Jallianwala Bagh. He proceeded there with about fifty troops, half British, half Indian, and a certain number of Ghurkas, armed with their kukris. The Jallianwala Bagh is an open space, half a mile square, which has one entry wide enough for three persons. The troops got in and lined up on a mound of debris. The walls, seven feet high, and the surrounding houses enclosed the people. There were, too, three alleys through which the people might have been able to pass. Within thirty seconds of the troops getting in, General Dyer gave orders to fire, and the crowd of people, estimated at anything from 5,000 to 20,000, who were sitting on the ground peacefully listening to the mob oratory, were fired on. The result of the troops’ fire into the mass of people we do not know. But we do know that Dyer’s own estimate of the casualties resulting from ten minutes continual individual firing, was 400 to 500 killed and 1,500 wounded. The people were not able to escape. They were people who had not offered any violence and who had not been warned. These people were shot down. After ten minutes, the ammunition was exhausted and the troops marched off, and they left 1,500 wounded there. There were men lying there for two days, dying of thirst, eating the ground, bleeding to death and nobody to look after them. Those who lived nearby came and carried away some of the wounded from the heap of dead and dying, but the unfortunate country people died there miserably of their wounds. This is what is done in 1919 in British India…
Centuries hence you will find Indian children brought up to this spot, just as they visit now the Cawnpore Well, and you can imagine the feelings of these Indians for generations over this terrible business.
[Col. Wedgwood, MP, speaking in the British Parliament, 22 December 1919] - On 26th January 1950, we are going to enter into a life of contradictions. In politics, we will have equality and in social and economic structure, continue to deny the principle of one man one value. How long shall we continue to live this life of contradictions? How long shall we continue to deny equality in our social and economic life? If we continue to deny it for long, we will do so only by putting our political democracy in peril. We must remove this contradiction at the earliest possible moment else those who suffer from inequality will blow up the structure of democracy, which this Constituent Assembly has so laboriously built up.
I feel that the constitution is workable, it is flexible and it is strong enough to hold the country together both in peacetime and in wartime. Indeed, if I may say so, if things go wrong under the new Constitution, the reason will not be that we had a bad Constitution. What we will have to say is that man was vile?
The third thing we must do is not be content with mere political democracy. We must note that our political democracy cannot last unless there lies at the base of social democracy. What does social democracy mean? It means a way of life, which recognizes liberty, equality and fraternity as the principles of life.
… however, good a constitution may be, it is sure to turn out bad because those who are called to work it, happen to be a bad lot. However, bad a constitution may be, it may turn out to be good if those who are called to work it, happen to be a good lot. The working of a Constitution does not depend wholly upon the nature of the Constitution.
[Excerpts from Dr. Ambedkar’s address to the Constituent Assembly, 25 November 1949] - There is really nothing new, not already anticipated in a distressed planet since the emergence of human species life nearly two million years ago. So, a long prehistory of inter-faith dialogue entailing the reciprocal relation between religious traditions and the robustness of the very idea of being human and having rights, precedes the recent UN movement of faith for rights (F4R). The F4R framework has finally been affirmed by the United Nations system. The Office of the High Commissioner for Human Rights (OCHR) promoted the Rabat plan of action in 2012. Note that this happened after the end of the Cold War, during globalisation, and soon after 9/11. The plan was a result of a series of expert workshops on the prohibition of incitement to national, racial or religious hatred, underlying “legislative patterns, judicial practices and policies”. The UN Human Rights Council is shortly going to discuss further the prohibition of the advocacy of national, racial or religious hatred that constitutes incitement to “discrimination, hostility or violence”.
- Prime Minister Narendra Modi on Saturday said major global firms are looking at India as a major investment destination, which is reflected by a robust inflow of Foreign Direct Investment (FDI) last financial year, and through ‘Atmanirbhar Bharat Abhiyan‘ (Self Reliant India initiative) the country is shifting its focus from ’Make in India‘ to ‗Make for world‘. He said Independent India should be "vocal for local" and asked citizens to glorify Indian products to promote 'Atmanirbhar Bharat‘. Unveiling his vision of a Self-Reliant India, the Prime Minister said that the government has unveiled over Rs 110 lakh crore National Infrastructure Pipeline (NIP) to boost the economy and create jobs. “In order to rapidly modernise India, there is a need to give a new direction to overall infrastructure development,” he said, adding that over 7,000 projects under NIP have been already identified. “This will be, in a way, a new revolution in the field of infrastructure. This is the time to end silos in infrastructure. There is a plan to connect the entire country with multi model connectivity infrastructure,” he said. NIP will play a crucial role in overcoming the adverse impact of Covid-19 on the economy and catapult the economy in a higher growth trajectory, he said. The government on December 31 last year unveiled the NIP with an aim to make India a $5 trillion economy by 2024-25. The focus of the infrastructure pipeline is to accelerate growth and create employment in both urban and rural areas.
- One thing struck us as a major difference between the new National Education Policy (NEP) 2020 and its predecessor. The earlier national policies on education (NPE) from 1986 and 1992 presented themselves as attempts to consolidate and build on earlier efforts, particularly the NPE, 1968. The new NEP 2020 policy, on the other hand, is very keen to establish that it is different from everything in the past, including in its name. Nowhere does this attitude come across as starkly as it does in the section on higher education.
It comes across fairly clearly on how the higher education ecosystem will be by 2040. By this time — if the policy has its way — the Indian higher education ecosystem will be populated with higher education institutions (HEI). These will comprise Universities and Colleges and the public and private sectors, all of which will be 'multi-disciplinary‘, with each populated by more than 3,000 students, with at least one “in or near every district”. Universities will conduct research and post-graduate and under-graduate teaching, some research-intensive and others teaching-intensive. Colleges will largely teach at the under-graduate level, with a number of them having their medium of instruction in either bilingual or local / Indian languages. The colleges can manifest in clusters around universities as constituent colleges or may be standalone autonomous ones. Ideally, all HEIs will eventually become “independent self-governing institutions” with considerable “faculty and institutional autonomy”. They will have complied with a series of regulatory exercises that are “light-but-tight” and will be operated by a large number of private accreditors, overseen by a new set of regulatory institutions at the national level.

- In the realm of contemporary literature, the interplay between character and setting is a nuanced dance that shapes the narrative’s essence. The setting, often described with painstaking detail, becomes more than a backdrop; it becomes a character, influencing the plot and character development.
Consider, for instance, the barren expanse of the desert in Jhumpa Lahiri’s The Namesake. The arid landscape mirrors the sense of isolation felt by the protagonist, Gogol, as he navigates his identity crisis in a foreign land. The relentless sun and vast sands are not mere descriptions; they are the silent witnesses to his inner turmoil.
On the other end of the literary spectrum, there is Arundhati Roy’s The God of Small Things. The lush, vibrant Kerala backwaters are not just the setting; they are a character woven into the fabric of the story. The teeming, humid landscape reflects the complex web of human relationships and secrets that unravel in the narrative. This interplay is not confined to contemporary literature alone. In Shakespeare’s timeless tragedy Macbeth, the eerie and foreboding setting of the Scottish moors casts a dark shadow over the characters’ actions. The moors, shrouded in mist and mystery, serve as an ever-present omen of the impending tragedy. - The crisis of justice that is the subject matter of discussion in the media today is in fact the crisis of “justice for the middle class”. The main difference between India and the OECD (Organisation for Economic Cooperation and Development) countries is that whereas the middle class in these countries has reasonable access to justice, in India it does not. A vocal and powerful middle class has emerged in India since 1991. It is demanding reasonable access to justice. Much of the judicial reform effort will help meet this demand…
The question of justice for the poor is, however, an altogether different challenge. No country in the world has been able to secure justice for the poor. Most of the jails of the richest countries are filled with the poorest. The “masses” are more often victims of the criminal justice system than of crime. In India as well, jails are almost exclusively filled with the poor. The civil justice system is hardly accessible to them. They are often victimised by lawyers, touts and court staff. They are docket-excluded, a new type of untouchability. The language and the logic—and the colonial and feudal culture—of the judicial system are alien to them. It rarely takes cognisance of their needs and interests.
Their main concern, therefore, is to escape the attention of the justice system, criminal and civil. A landless Dalit person in the interior of Madhya Pradesh once gave me an insightful definition of a court from the perspective of the masses: “A court is a place where you are forcibly taken by the police to be punished; no one goes to a court.” In contrast, many lawyers and judges colloquially define a court as “a temple of justice where rights are protected”.
These sharply divergent visions mean that justice for one section is often injustice for another. Protecting the livelihood of traditional taxi and auto drivers from predatory pricing by corporate app-based taxi providers by imaginatively using the available tools of law to delay their incursion would be seen by the rich and by sections of the middle class as a failure of the judicial system, and possibly as also resulting in a downgrading of the “ease of doing business” measure. However, the masses would see such a judicial intervention as strong evidence of a good justice system. Although the conflict over competing visions of the nation and conflicting demands from social and economic segments have confined judicial reform of judicial administration mainly to “neutral” areas such as process reform, procedural law, technology, planning and court and case management, judge strength, and the workload of judges, there has been considerable improvement in these areas, and the judicial system has improved its performance.
[Extracted, with edits, from “Justice and the Two Ideas of India”, by G. Mohan Gopal, Frontline] - Everything she wanted was here, at Carignano, in Kasauli. Here, on the ridge of the mountain, in this quiet house. It was the place, and the time of life, that she had wanted and prepared for all her life-as she realized on the first day at Carignano, with a great, cool flowering of relief - and at last she had it. She wanted no one and nothing else. Whatever else came, or happened here, would be an unwelcome intrusion and distraction. This she tried to convey to the plodding postman with a cold and piercing stare from the height of the ridge onto his honest bull back. Unfortunately, he did not look up at her on the hilltop but stared stolidly down at the dust piling onto his shoes as he plodded on. A bullock-man, an oafish ox, she thought bitterly. She stepped backwards into the garden and the wind suddenly billowed up and threw the pine branches about as though to curtain her. She was grey, tall and thin and her silk sari made a sweeping, shivering sound and she fancied she could merge with the pine trees and be mistaken for one. To be a tree, no more and no less, was all she was prepared to undertake.
What pleased and satisfied her so, here at Carignano, was its barrenness. This was the chief virtue of all Kasauli of course-its starkness. It had rocks, it had pines, it had light and air. In every direction there was a sweeping view - to the north, of the mountains, to the south, of the plains. Occasionally an eagle swam through this clear unobstructed mass of light and air, that was all. And Carignano, her home on the ridge, had no more than that. Why should it? The sun shone on its white walls. Its windows were open the ones facing north opened on to the blue waves of the Himalayas flowing out and up to the line of ice and snow sketched upon the sky, while those that faced south looked down the plunging cliff to the plain stretching out, flat and sere to the blurred horizon.
Yes, there were some apricot trees close to the house. There were clumps of iris that had finished blooming. There was the kitchen with a wing of smoke lifting out of its chimney and a stack of wood outside its door. But these were incidental, almost unimportant.
[Extracted, with edits and revisions, from “Fire on the Mountain” by Anita Desai] - English literature is a vast and diverse field that has left an indelible mark on the world of letters. From the eloquent plays of William Shakespeare to the complex novels of Jane Austen and the profound poetry of William Wordsworth, English literature offers a window into the human experience. One of the luminaries of English literature is William Shakespeare, often hailed as the greatest playwright in the history of English language. His works, including Hamlet, Macbeth, and Romeo and Juliet, are celebrated for their exploration of human nature, love, ambition, and tragedy. His characters, such as the tormented Hamlet and the star-crossed lovers Romeo and Juliet, continue to captivate readers and audiences worldwide.
The 19th century ushered in a new era of literary giants. Jane Austen’s novels, such as Pride and Prejudice and Sense and Sensibility, provide incisive social commentary through the lens of wit and romance. Austen’s heroines, like Elizabeth Bennet and Elinor Dashwood, remain beloved literary figures known for their intelligence and resilience. The Romantic era brought forth poets like William Wordsworth and Samuel Taylor Coleridge, who celebrated * 8 UG the beauty of nature and the emotional intensity of the individual. Wordsworth’s ‘‘I Wandered Lonely as a Cloud’’ and Coleridge’s ‘‘The Rime of the Ancient Mariner’’ are testament to the power of the written words to evoke profound emotions and imagery. Moving towards 20th century, English literature continued to evolve. Virginia Woolf’s ground-breaking novel Mrs. Dalloway explored the inner thoughts and lives of its characters with a modernist narrative style. Dystopian visions, as seen in George Orwell’s Nineteen Eighty-Four provided stark warnings about the dangers of totalitarianism and the erosion of individual freedom.
Today, English literature is a global phenomenon, transcending borders and languages. Indian authors like Arundhati Roy, with her novel The God of Small Things, have won prestigious international literary awards. The book not only explores intricate family dynamics but also delves into the broader socio-political landscape of India. In summary, English literature is a testament to the enduring power of storytelling and the written word. It encompasses an array of authors, themes, and styles that continue to captivate and inspire readers across the world. - On the evening of the 10th, General Dyer arrived at Amritsar, and the Deputy-Commissioner handed over the civil power to him.
