उत्तर
The theme of the paragraph is the formation of glaciers. Thus, sentence C should start the paragraph. In sentence D, “they” refers to “most glaciers.” Naturally, sentence D should follow. Then comes sentence A as “all year round” and “in the following years” are connected. At the end comes sentence B. “Solid ice” refers to glaciers.
Therefore, CDAB is the correct option.

1. Often, we passionately pursue matters that in the future appear to be contradictory to our real intention or nature; and triumph is followed by remorse or regret. There are numerous examples of such a trend in the annals of history and contemporary life.
2. Alfred Nobel was the son of Immanuel Nobel, an inventor who experimented extensively with explosives. Alfred too carried out research and experiments with a large range of chemicals; he found new methods to blast rocks for the construction of roads and bridges; he was engaged in the development of technology and different weapons; his life revolved around rockets and cannons and gun powder. The ingenuity of the scientist brought him enough wealth to buy the Bofors armament plant in Sweden.
3. Paradoxically, Nobel's life was a busy one yet he was lonely; and as he grew older, he began suffering from guilt of having invented the dynamite that was being used for destructive purposes. He set aside a huge part of his wealth to institute Nobel Prizes. Besides honouring men and women for their extraordinary achievements in physics, chemistry, medicine and literature, he wished to honour people who worked for the promotion of peace.
4. It's strange that the very man whose name was closely connected with explosives and inventions that helped in waging wars willed a large part of his earnings for the people who work for the promotion of peace and the benefit of mankind. The Nobel Peace Prize is intended for a person who has accomplished the best work for fraternity among nations, for abolition or reduction of war and for promotion of peace.
5. Another example that comes to one's mind is that of Albert Einstein. In 1939, fearing that the Nazis would win the race to build the world's first atomic bomb, Einstein urged President Franklin D Roosevelt to launch an American programme on nuclear research. The matter was considered and a project called the Manhattan Project was initiated. The project involved intense nuclear research the construction of the world's first atomic bomb. All this while, Einstein had the impression that the bomb would be used to protect the world from the Nazis. But in 1945, when Hiroshima was bombed to end World War II, Einstein was deeply grieved and he regretted his endorsement of the need for nuclear research.
6. He also stated that had he known that the Germans would be unsuccessful in making the atomic bomb, he would have probably never recommended making one. In 1947, Einstein began working for the cause of disarmament. But, Einstein's name still continues to be linked with the bomb.
Man's fluctuating thoughts, changing opinions, varying opportunities keep the mind in a state of flux. Hence, the paradox of life: it's certain that nothing is certain in life.

Paragraph: China’s rising power is based on its remarkable economic success. Shanghai’s overall economy is currently growing at around 13% per year, thus doubling in size every five or six years. Everywhere there are start-ups, innovations, and young entrepreneurs hungry for profits. In a series of high-level meetings between Chinese and African officials, the advice that the African leaders received from the Chinese was sound and more practical than they typically get from the World Bank. Chinese officials stress the crucial role of public investments, especially in agriculture and infrastructure, to lay the basis for private sector-led growth. In a hungry and poor rural economy, as China was in the 1970s and as most of Africa is today, a key starting point is to raise farm productivity. Farmers need the benefits of fertilizer, irrigation and high-yield seeds, all of which were a core part of China’s economical take off. Two other equally critical investments are also needed: roads and electricity, without which there cannot be a modern economy. Farmers might be able to increase their output, but it won’t be able to reach the cities, and the cities won’t be able to provide the countryside with inputs. The government has taken pains to ensure that electricity grids and transportation networks reach every village in China. China is prepared to help Africa in substantial ways in agriculture, roads, power, health and education. And that is not an empty boast. Chinese leaders are prepared to share new high yield rice varieties, with their African counterparts and, all over Africa, China is financing and constructing basic infrastructure.
This illustrates what is wrong with the World Bank. The World Bank has often forgotten the most basic lessons of development, preferring to lecture the poor and force them to privatize basic infrastructure, which is untenable, rather than to help the poor to invest in infrastructure and other crucial sectors. The Banks’ failure began in the early 1980s when under the ideological sway of the American President and British Prime Minister tried to get Africa and other poor regions to cut back or close down government investments and services. For 25 years, the bank tries to get governments out of agriculture, leaving impoverished peasants to fend for themselves. The result has been a disaster in Africa, with farm productivity stagnant for decades. The bank also pushed for privatization of national health systems, water utilities, and road and power networks, and has grossly underfinanced these critical sectors. This extreme free-market ideology, also called “structural adjustment”, went against the practical lessons of development successes in China and the rest of Asia. Practical development strategy recognizes that public investments - in agriculture, health, education, and infrastructure- are necessary complements to private investments. The World Bank has instead wrongly seen such vital public investments as an enemy of private sector development. Whenever the banks’ ideology failed, it has blamed the poor for corruption, mismanagement, or lack of initiative. Instead of focusing its attention on helping the poorest countries to improve their infrastructure, there has been a crusade against corruption. The good news is that African governments are getting the message on how to spur economic growth and are getting crucial help from China and other partners that are less wedded to extreme free-market ideology than the world Bank. They have declared their intention to invest in infrastructure, agriculture modernistation, public health, and education. It is clear the Bank can regain its relevance only if it becomes practical once again, by returning its focus to financing public investments in priority sectors. If that happens, the Bank can still do justice to the bold vision of a world of shared prosperity that prompted its creation after World War II.

Paragraph: On the surface, the conquest of the Aztec empire by Herman Cortes is one of the most amazing military accomplishments in history. With a small fighting force numbering in the hundreds, Cortes led the Spanish explorers into victory against an Aztec population that many believe topped 21 million. In light of such a seemingly impossible victory, the obvious question is: how did a small group of foreign fighters manage to topple one of the world's strongest, wealthiest, and most successful military empires?
Several factors led to Cortes' success. First, the Spanish exploited animosity toward the Aztecs among rival groups and convinced thousands of locals to fight. In one account of a battle, it is recorded that at least 200,000 natives fought with Cortes. Next, the Spanish possessed superior military equipment in the form of European cannons, guns, and crossbows, leading to effective and efficient disposal of Aztec defenses. For example, Spanish cannons quickly defeated large Aztec walls that had protected the empire against big and less technically advanced armies.
Despite the Spanish advantages, the Aztecs probably could have succeeded in defending their capital city of Tenochtitlan had they leveraged their incredible population base to increase their army's size and ensured that no rogue cities would ally with Cortes. In order to accomplish this later goal, Aztec leader Motecuhzoma needed to send envoys to neighboring cities telling their inhabitants about the horrors of Spanish conquest and the inevitability of Spanish betrayal.
In addition, the Aztecs should have exploited the fact that the battle was taking place on their territory. No reason existed for the Aztecs to consent to a conventional battle, which heavily favored the Spanish. Motecuhzoma's forces should have thought outside the box and allowed Cortes into the city, only to subsequently use hundreds of thousands of fighters to prevent escape and proceed in surprise "door-to-door" combat. With this type of battle, the Aztecs would have largely thwarted Spanish technological supremacy. However, in the end, the superior weaponry of the Spanish, the pent-up resentment of Aztec rivals, the failure of Aztec diplomacy, and the lack of an unconventional Aztec war plan led to one of the most surprising military outcomes in the past one thousand years.
The author implies which of the following about the nature of Aztec regional influence and power?
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 idea of flying an aircraft was _________ to some people.

One of the most prolific authors of all time, Isaac Asimov was influential both in science fiction and in the popularization of science during the twentieth century, but he is also justly famous for the scope of his interests. Although the common claim that Asimov is the only author to have written a book in every category of the Dewey decimal system is untrue, its spirit provides an accurate picture of the man: a dedicated humanist who lauded the far-reaching power of reason. His most famous work, the Foundation trilogy, can be read as an illustration of Asimov’s belief in reason and science, but even while he expressed that belief, science itself was calling it into question.
Foundation describes a time in which a vast Empire spanning the galaxy is on the verge of collapse. Its inevitable doom is a consequence not of its size, but of the shortsightedness of its leaders. In this environment, a scientist named Hari Seldon devises an all encompassing plan to help human civilization recover from the trauma of the Empire’s coming collapse. Using mathematics, Seldon is able to predict the future course of history for thousands of years, and he takes steps that are geared toward guiding that future in a beneficial direction. The trope of the benevolent and paternalistic scientist shaping existence from behind the scenes, present in much of Asimov’s fiction, is never more explicit than in the Foundation series, which describes with an epic sweep the course and progress of the Seldon Plan.
As naive and, perhaps, self-serving as the conceit of Foundation may seem to contemporary readers, it retains to some degree its ability of comfort by offering an antidote to the complex and unpredictable nature of experience. Science in Asimov’s time was, in popular conceptions, engaged in just this pursuit: discerning immutable laws that operate beneath a surface appearance of contingency, inexplicability, and change. But even while Asimov wrote, science itself was changing. In Physics, the study of matter at the subatomic level showed that indeterminacy was not a transitory difficulty to be overcome, but an essential physical principle. In Biology, the sense of evolution as steady progress toward better-adapted forms was being disturbed by proof of a past large-scale evolution taking place in brief explosions, of frantic change. At the time of Asimov’s death, even Mathematics was gaining popular notice for its interest in chaos and inexplicability. Usually summarized in terms of the so-called ‘butterfly effect’, chaos theory showed that perfect prediction could take place only on the basis of perfect information, which was by nature impossible to obtain. Science had dispensed with the very assumptions that motivated Asimov’s idealization of it in the Seldon Plan. Indeed, it was possible to see chaos at work in Foundation itself: as sequels multiplied and began to be tied into narrative threads from Asimov’s other novels, the urge to weave one grand narrative spawned myriad internal inconsistencies that were never resolved.
The author’s reference to a common claim made about Isaac Asimov, serves to
Read the given passage carefully and answer the questions that follow.
There is a fairly universal sentiment that the use of nuclear weapons is clearly contrary to morality and that its production probably so, does not go far enough. These activities are not only opposed to morality but also to law if the legal objection can be added to the moral, the argument against the use and the manufacture of these weapons will considerably be reinforced. Now the time is ripe to evaluate the responsibility of scientists who knowingly use their expertise for the construction of such weapons, which has deleterious effect on mankind.
To this must be added the fact that more than 50 percent of the skilled scientific manpower in the world is now engaged in the armaments industry. How appropriate it is that all this valuable skill should be devoted to the manufacture of weapons of death in a world of poverty is a question that must touch the scientific conscience.
A meeting of biologists on the Long-Term Worldwide Biological consequences of nuclear war added frightening dimension to those forecasts. Its report suggested that the long biological effects resulting from climatic changes may at least be as serious as the immediate ones. Sub-freezing temperatures, low light levels, and high doses of ionizing and ultraviolet radiation extending for many months after a large-scale nuclear war could destroy the biological support system of civilization, at least in the Northern Hemisphere. Productivity in natural and agricultural ecosystems could be severely restricted for a year or more. Post war survivors would face starvation as well as freezing conditions in the dark and be exposed to near lethal doses of radiation. If, as now seems possible, the Southern Hemisphere were affected also, global disruption of the biosphere could ensue. In any event, there would be severe consequences, even in the areas not affected directly, because of the interdependence of the world economy. In either case the extinction of a large fraction of the earth’s animals, plants and microorganism seems possible.
The population size of Homo sapiens conceivably could be reduced to prehistoric levels or below, and extinction of the human species itself cannot be excluded.

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 a 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.
According to the passage, the root cause of class conflict is
The questions section is based on the passage. The question is to be answered on the basis of what is stated or implied in the passage.
In principle, a cohesive group-one whose members generally agree with one another and support one another’s judgments do a much better job at decision making than it could if it were non-cohesive. When cohesiveness is low or lacking entirely, compliance out of fear of recrimination is likely to be strongest. To overcome this fear, participants in the group’s deliberations need to be confident that they are members in good standing and that the others will continue to value their role in the group, whether or not they agree about a particular issue under discussion. As members of a group feel more accepted by the others, they acquire greater freedom to say what they really think, becoming less likely to use deceitful arguments or to play it safe by dancing around the issues with vapid or conventional comments. Typically, then, the more cohesive a group becomes, the less its members will deliberately censor what they say out of fear of being punished socially for antagonizing their fellow members. But group cohesiveness can have pitfalls as well: while the members of a highly cohesive group can feel much freer to deviate from the majority, their desire for genuine concurrence on every important issue often inclines them not to use this freedom. In a highly cohesive group of decision-makers, the danger is not that individuals will conceal objections they harbor regarding a proposal favored by the majority, but that they will think the proposal is a good one without attempting to carry out critical scrutiny that could reveal grounds for strong objections. Members may then decide that any misgivings they feel are not worth pursuing that the benefit of any doubt should be given to the group consensus. In this way, they may fall victim to a syndrome known as ‘groupthink’, which one psychologist concerned with collective decision making has defined as ‘a deterioration of mental efficiency, reality testing, and moral judgment that results from in-group pressures’. Based on analyses of major fiascos of international diplomacy and military decision making, researchers have identified groupthink behaviour as a recurring pattern that involves several factors: overestimation of the group’s power and morality, manifested, for example, is an illusion of invulnerability, which creates excessive optimism;
closed-mindedness to warnings of problems and to alternative viewpoints; and unwarranted pressures toward uniformity, including self-censorship with respect to doubts about the group’s reasoning and a concomitant shared illusion of unanimity concerning group decisions. The cohesiveness of the decision-making group is an essential antecedent condition for this syndrome but not a sufficient one, so it is important to work toward identifying the additional factors that determine whether group cohesiveness will deteriorate into groupthink or allow for effective decision making.

Teaching, more even than most other professions, has been transformed during the last hundred years from a small, highly skilled profession concerned with a minority of the population, to a large and important branch of public service. The profession has a great and honourable tradition, extending from the dawn of history until recent times, but any teacher in the modern world who allows himself to be inspired by the ideals of his predecessors is likely to be made sharply aware that it is not his function to teach what he thinks, but to instill such beliefs and prejudices as are thought useful by his employers.

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?
