Explanation:
The paragraph discusses the relationship between the Earth's orbital tilt, climate change, and the melting of ice in Greenland. Let's analyze the given sentences to determine the most logical order.

Sentence A: According to scientists from NASA's Jet Propulsion Laboratory, the current melting of ice in Greenland is already causing the tilt to change at a rate of approximately 2.6 cm each year.
This sentence introduces the idea that the melting of ice in Greenland is affecting the Earth's tilt. It provides specific information about the rate of change caused by the melting ice.

Sentence B: While a natural event such as this could bring about major changes to the climate, some scientists are warning that there is a possibility for reverse feedback.
This sentence discusses the potential effects of the changing tilt on the climate. It introduces the concept of reverse feedback, indicating that there may be a reciprocal relationship between the tilt and climate change.

Sentence C: The Earth's orbital tilt is said to vary between 22 and 25 degrees roughly every 41,000 years.
This sentence provides general information about the Earth's orbital tilt. It establishes a baseline understanding of the tilt's natural variation.

Sentence D: In other words, instead of an orbital tilt causing climate change, current changes in climate could end up causing changes in the Earth's axial tilt.
This sentence concludes the paragraph by summarizing the main idea. It suggests that instead of the tilt causing climate change, climate change could potentially affect the tilt.

Logical Order:
Based on the analysis, the most logical order of the sentences is as follows:

Community Answer
Direction: The sentences given in the question, when properly sequence...
Sentence A states that the current melting of ice in Greenland is causing “the tilt"? to change at a rate of 2.6 cm a year. Let us look at the other sentences to see what “the tilt"? refers to. We see that sentence C clarifies this. Sentence C tells us that “the Earth’s orbital tilt"? varies between 22 and 25 degrees very 41,000 years. There is however, no cogent link between sentences A and C. We can just say at this point that A follows C, but not immediately after.
Now sentence D begins with “in other words"? and states that while an orbital tilt causes climate change, current changes in climate could end up causing changes in the Earth's axial tilt. Which sentence is sentence D paraphrasing? The only and obvious choice is sentence B, which says that though a natural event could bring about climate change, scientists are warning of a possibility for “reverse feedback"?. So D follows B.
What is the “natural event"? referred to in sentence B? The melting of ice in Greenland, or the variation in the Earth’s orbital tilt? Clearly, it is the latter. So B follows C.
The point about the melting of ice in Greenland changing the tilt is made to substantiate the theory that climate change can cause the Earth’s axial tilt to change.
The question is " Arrange the sentences in the correct order "
The order is CBDA
Hence, the answer is CBDA
Choice C is the correct answer.

DIRECTIONSfor the question:Read the passage and answer the question based on it.A new source of methane – a greenhouse gas many times more powerful than carbon dioxide – has been identified by scientists flying over areas in the Arctic where the sea ice has melted.The researchers found significant amounts of methane being released from the ocean into the atmosphere through cracks in the melting sea ice. They said the quantities could be large enough to affect the global climate. Previous observations have pointed to large methane plumes being released from the seabed in the relatively shallow sea off the northern coast of Siberia but the latest findings were made far away from land in the deep, open ocean where the surface is usually capped by ice.Eric Kort of Nasas Jet Propulsion Laboratory in Pasadena, California, said that he and his colleagues were surprised to see methane levels rise so dramatically each time their research aircraft flew over cracks in the sea ice."When we flew over completely solid sea ice, we didnt see anything in terms of methane. But when we flew over areas were the sea ice had melted, or where there were cracks in the ice, we saw the methane levels increase," Dr Kort said. "We were surprised to see these enhanced methane levels at these high latitudes. Our observations really point to the ocean surface as the source, which was not what we had expected," he said."Other scientists had seen high concentrations of methane in the sea surface but nobody had expected to see it being released into the atmosphere in this way," he added.Methane is about 70 times more potent as a greenhouse gas than carbon dioxide when it comes to trapping heat. However, because methane is broken down more quickly in the atmosphere, scientists calculate that it is 20 times more powerful over a 100-year cycle. The latest methane measurements were made from the American HIPPO research programme where a research aircraft loaded with scientific instruments flies for long distances at varying altitudes, measuring and recording gas levels at different heights.The study, published in the journal Nature Geoscience, covered several flights into the Arctic at different times of the year. They covered an area about 950 miles north of the coast of Alaska and about 350 miles south of the North Pole. Dr Kort said that the levels of methane coming off this region were about the same as the quantities measured by other scientists monitoring methane levels above the shallow sea of the East Siberian Arctic Shelf."We suggest that the surface waters of the Arctic Ocean represent a potentially important source of methane, which could prove sensitive to changes in sea ice cover," the researchers write. "The association with sea ice makes this methane source likely to be sensitive to changing Arctic ice cover and dynamics, providing an unrecognised feedback process in the global atmosphere-climate system," they say.Climate scientists are concerned that rising temperatures in the Arctic could trigger climate-feedbacks, where melting ice results in the release of methane which in turn results in a further increase in temperatures.Q.What pertinent question would you ask the scientist after reading the passage?

Directions:The passage below is accompanied by a set of questions. Choose the best answer to each question.The young scientist in India is an endangered species. The threat comes from the predatory habits of a more evolved species that is the senior scientist. An Indian university teacher in a letter to the international science journalNaturewrote plaintively: Thesis supervisors take undue credit for the work of their protégés. A young scientist needs the goodwill and support of the scientist-in-power at every step: for completion and continuation of his work, for participation in national and international meetings and research projects, for recognition and reward and for promotion. This support is available but at a price. The price often is the sharing of credit. A worthwhile research paper or a project originating from a humble scientist would often end up with the scientist-in-power as the principal author or investigator.The power of the senior scientist over his junior stems from the fact that science is the only profession in the world which is self-assessing. Unlike in the bureaucracy or the military where the top authority vests with non-professionals, a scientists work can be overseen and evaluated only by fellow scientists.Fortunately for the scientists, support for science is a badge of honour for nations aspiring to modernity. That is why the government which normally would not pay the piper unless it can call the tune, happily makes an exception in the case of science. Society values continuity, stability and security, and turns to the past for guidance and support. Science, on the other hand, aspires to instability. It aims at creating something that did not exist before. It seeks a break with the past with an eye on the future.It is an irony that in todays world, feudalism can be sustained only in the administration of a modern scientific research centre. One must, however, not be unfair to the feudal lords of yesteryears whose conduct had the sanction of the times. Neo-feudalism is pernicious because it is anachronistic; it can be sustained only by a subversion of the system in the hands of the people who are entrusted with the task of upholding it.If we define professionalism as the realisation that an institution ranks higher than an individual and that the collective goal is more important than individual ego, it must be admitted that we are unprofessional people. It is wrong in principle to give any individual a larger-than-the-institution image. This philosophy becomes all the more debilitating, because recently there has been an alarming decline in the quality of leadership in science as in other walks of life. It is relatively speaking an easy matter to evaluate a leader. His commitment can be judged by asking whether he is giving to the system or taking from it. The calibre of a leader can be gauged from the calibre of the people willing to play second fiddle to him.Under these circumstances, if a chief executive is to be projected as the master of an institution rather than its servant, this can be done only by degrading the institution. It will be like a cinema hall whose facade remains the same, but the posters outside and the picture inside go on changing.Q.The author suggests that the power which a senior scientist exercises over his juniors is due to
