OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 1

                                                                                   Passage 1

There's been a change in the weather. Extreme events like the Nashville flood - described by officials as a once - in - a - millennium occurrence - are happening more frequently than they used to. A month before Nashville, torrential downpours dumped 11 inches of rain on Rio de janeiro in 24 hours, triggering mud slides that buried hundreds. About three months after Nashville, record rain in Pakistan caused flooding that affected more than 20 million people. In late 2011, floods in Thailand submerged hundreds of factories near Bangkok, creating a worldwide shortage of computer hard drives.

And it is not just heavy rains that are making headlines. During the past decade we have also been severe droughts in places like Texas, Australia and Russia as well as in East Africa, where tens of thousands have taken refuge in camps. Deadly heat waves hit Europe, and record numbers of tornadoes have ripped across the United States. Losses from such events helped push the cost of whether disasters in 2011 to an estimated $150 billion worldwide, a roughly 25% jump from the previous year. In the USA, last year, a record 14 events caused a billion dollars or more of damage each, far exceeding the previous record of 9 such disasters in 2008.

What is going on? Are these extreme events signals of a dangerous, human made shift in Earth's climate? Or are we just going through a natural stretch of bad luck?

The short answer is: probably both. The primary forces driving recent disasters have been natural climate cycles, especially El Nino and La Nina. Scientists have learned a lot during the past few decades about how that strange seesaw in the equatorial Pacific affects weather worldwide. During an El Nino, a giant pool of warm water that normally sits in the central Pacific surges east all the way to South America; during a La Nina, it shrinks and retreats into the Western Pacific. Heat and water vapour coming off the warm pool generate thunderstorms so powerful and towering that their influence extends out of the tropics to the jet streams that blow across the middle altitudes. As the warm pool shifts back and forth along the equator, the wavy paths of the jet streams shift north and south- which changes the tracks that storms follow across the continents. An El Nino tends to push directing storms over the southern USA and Peru while visiting drought and fire on Australia. In a La Nina, the rains flood Australia and fail in the American Southwest and Texas - and in even more distant places like East Africa.

 

Q. The passage attempts to describe which of the following...  

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 1

The passage is primarily about the reasons behind weather disasters. The damage and monetary losses are presented in the introduction to describe the extent to which the weather has changed. Thus option b is correct.

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 2

                                                                                   Passage 3

With the advancement in the frontiers of science, there is an emerging demand for hi-tech minerals, which will have to be met. This will call for earth scientists anticipating demand and exploring and extracting these minerals with cost effective and environment friendly extraction technologies. Agencies of both ofthe central and state governments will have to play an important promotional role in the exploration of these minerals.

The mineral surveys and exploration programmes to be carried out by the central and state agencies will also have to be targeted to take up concept oriented studies integrating geological, geo-physical and geochemical surveys appropriately linked up with laboratory studies involving state ofthe art technologies. Deeper probing of known deposits; intensive and extensive belt wise mineral exploration including covering areas out of the traditional mineral belts and even basement rocks will also have to be undertaken.

Concerted action plans need to be drawn up by the concerned organisations to acquire higher capability in all fields of mineral exploration and development. This will call for technology upgradation for field data acquisition, state of the art laboratory back up and development of expertise. Focus areas will include air-borne surveys, ground geophysical surveys, exploratory drilling, marine survey, etc.

 

Q. Consider the following statements:

1. Meeting the emerging demand for hi-tech minerals is an imperative.

2. Advancements in science have resulted in emerging demand for hi-tech minerals. With reference to the passage, which of the following statements is/are valid?

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 2

As the first sentence of the passage tells that the emerging demand for hi-tech minerals will have to be met, one can say that meeting the emerging demand for hi-tech minerals in an imperative. Statement 2 is invalid as the first sentence of the passage tells us that due to the advancement in science, the demand for hi-tech minerals has emerged. Hence, option c is correct.

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 7

Directions (Q. 16-25) select the most appropriate answer.

Your company is undergoing a serious economic peril. The only way out of this situation is to urgently bring in some public money into the company. However, some of the Directors in the company are against this idea as they think that the time is not ripe for raising public money. You will​

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 7

As the situation demands it, using the veto and going ahead with the plan is the best option. Option c comes next but it may prove to be time consuming whereas the matter at hand is urgent. Going with the option a is next but it would show that you give up too easily. Option d is the worst choice as it will portray you as a quitter.

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 8

You have just found that one of your colleagues has been using his official position to secretly demand gifts and favors from the vendors who supply materials to your organization, with the promise to finalize the contract in their favor. Given this situation you will,  

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 8

The best course would be to approach the Ethics Committee. Any proceedings of the committee would be part of official record and the committee would also have the authority to ensure compliance would also have the authority to ensure compliance with its decision. Moreover, since there is a clear company policy regarding such behaviour, you should follow the method prescribed in the policy for dealing with such a situation. The next best option would be to speak to your colleague directly. Ignoring the matter would not be in your interest of your organization. Similarly contacting the vendors would not deal with the root of the problem since the vendors are only responding to the other made by your colleagues in order to secure their own business.

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 9

You are the District Magistrate. There has been an incident in the government hospital. A mob went on a rampage in the hospital after a child admitted with head injuries died allegedly due to the negligence of the Medical Officer on duty. Now the medical officers have complained to you saying that it is impossible to work in such a threatening environment. You will   

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 9

Assuring the locals that a proper investigation of the case will take place will help in pacifying them. Hence, option d is the best course of action. Since the medical officers are also agitated and are refusing the allegation, assuring them that the matter will be thoroughly investigated is the next best option. You cannot reprimand the medical officer as the death due to his negligence is the allegation at the moment. Thus, option b is negated. The medical officer's apology is welcome but it will not compensate their loss in anyway. Hence option c is also negated.

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 10

You are working as an HR manager in an educational organization. The company is facing a financial crunch and as a consequence there are consistent salary disbursement delays. The training staff at one of the centers is highly agitated and refuses to take classes. You will  

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 10

A situation such as this, requires employees' support and cooperation. The best possible option is to keep things transparent so as to gain the employees' trust and commitment towards the organization. Hence option d is the best choice. Option a is the next best course of action as it clarifies to the employees that they are not alone in facing this problem and appeals to the sense of community and belonging with the others in the organization. Putting pressure on the finance department will not help resolve the issue because the company has no money in the first place. Moreover, releasing salaries for only one center can worsen the situation at other centers. Threatening the staff will aggravate the situation and not solve it as the company is at fault and not the employees. Thus options b and c are negated.

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 11

                                                                                   Passage - 2

When the late evolutionist and polymath Stephen Jay Gould was a toddler, he became fascinated and terrified by the towering Tyrannosaurus rex skeleton at the American Museum of Natural History. Gould later claimed that he decided on the spot to become a palaeontologist- years before he even learned the word. Steven Pinker does not believe this oft told story. Pinker relates that Gould dedicated his first book: "For my father, who took me to see the Tyrannosaurus when I was five" and admires Gould's genius for coming up with that charming line, "But he does not believe it. Pinker says that long term memory is notoriously untrustworthy. Many children are exposed to books and museums, but few become scientists. Pinker concludes that perhaps the essence of who we are from birth shapes our childhood experiences rather than the other way round.

 

Q. Steven Pinker

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 11

Nowhere in the passage it has been mentioned that he was a palaeontologist or a psychologist or the writer of a book. That leaves us only with option b.

                                                                                  Passage - 3

For want of a better job, Orwell took a job with the Burmese civil service. It was here in Burma, that Orwell begin to assert his independence from his privileged upbringing. Revealingly, Orwell later told that he found himself rooting for the local population; and despising the imperial ideology which he represented. He resigned from his position in 1927.

It was in the nature of Orwell to try and see a situation from other people's point of view. He was unhappy at accepting the conventional social wisdom. In fact, he grew to despise the middle class upbringing so much so that he decided to spend time as a tramp. He wanted to experience life from the view of the gutter. His vivid experiences are recorded in the book "Down and Out in Paris and London". No longer could Orwell be described as a "Champagne Socialist"; by living with the poorest and underprivileged, he gained a unique insight into the practical working class ideas and working class politics

 

Q. Orwell-

1. loved his job with the Burmese Civil Service

2. did not have a privileged upbringing

Choose the correct option using the codes given below:

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 13

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 14

Directions(Q.34-40) for the following items:

Each of the items below consists of a question and two statements. You have to decide whether the data provided in the statements are sufficient to answer the question. Give answer as: 

 

Statements:

I. There are ten students between Nitin and Deepak.

II. Deepak is twentieth from the top.

 

Q. What is Nitin's rank from the top in a class of forty students?

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 14

Since there are ten students between Nitin and Deepak, so Nitin may be eleven ranks above or below Deepak. Thus, Nitin may be 9th or 31st from the top.

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 15

Statements:

I. If Sunny turns to his right and again turns to his right, he will be facing the North.

II. If Sunny walks some distance and turns left and again walks some distance, then his face will be towards left of Dinesh who is facing the South.

 

Q. Which direction is Sunny facing now?

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 15

From I, we conclude that Sunny is facing South, since a person facing South shall face North on turning to his right, twice.

From II, we know that after walking, Sunny shall face towards left of Dinesh facing South i.e. East and a person walking southwards shall face East on turning to 'his left.

Thus, Sunny is facing the South.

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 16

Statements:

I. T does not study in the same school as either R or J.

II. R and J study in schools D and F respectively.

 

Q. T studies in which of the schools B, C, D, E and F?

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 16

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 17

Statements:

I. Divya's mother is sister of Shaloo's father.

II. Shaloo is the daughter of Divya's grandfather's only child.

 

Q. How is Divya related to Shaloo?

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 17

From I, we conclude that Divya's mother is Shaloo's aunt or Divya is Shaloo's cousin.

Now, Divya's grandfather's only child is Divya's parent. So, from II, we conclude that Shaloo and Divya are daughters of the same parents i.e. Divya is Shaloo's sister.

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 18

Statements:

I. Last year 2935 cards were sold.

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 19

You had rented out a tenement to a group of five labourers who claimed to be extremely poor and wanted a discount on the rent. You agreed to rent them the place for a very low amount keeping in mind their impoverished condition. For some months they delayed paying the rent on the pretext of non-payment of wages by their employer. One day you found that the tenement is vacated and theses labourers are nowhere to be found and the rent for several months was due on them. You will   

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 19

Option c is the best choice as for the labourers to deceive you in such a manner and leave without paying the money they owe you, is tantamount to theft and you should definitely inform the police. Option b is the next best course as you have been civil enough to understand their problem and offer them discount as well as significant leeway in paying rent. Option a is incorrect as it would mean that you let yourself be wronged without taking any steps to rectify the situation. Option d is incorrect as it does not solve the problem at hand in any way.

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 20

You are working as a supply supervisor in a leading oil company in the public sector. It has come to your attention that certain company officials are stealing petrol from the company's plant and adulterating the remaining to cover up their tracks. They can sell the stolen petrol illegally to make a neat profit. You would  

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 20

Option b is the best choice as it is your duty to bring the matter to the attention to the authorities. Option d is the next best choice since, if for some reason, you are unable to escalate the matter to higher authorities, it would be best to bring the matter to light by taking recourse to the media.

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 21

You are a student in a government operated intermediate school. Some children from the economically weaker sections have been admitted to this school. You observe that the teachers and the students from affluent families are biased against these children. You will  

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 21

Option a is the best choice as the principal should be informed about this so that he can take the required action to ensure that such practices are discontinued. Option c is the next best choice in case the principal does not respond to your request. Option b is incorrect as ignoring it would mean that you are an apathetic person and do not take proactive steps if you see something wrong. Option d is incorrect as your parents may not be in a position to influence matters at school.

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 22

                                                                                    Passage 2

A report out today warns that even in a fast growing economy like India, failure to invest in agriculture and support small farms has left nearly half the country's children malnourished, with one fifth of the one-billion plus population being hungry.

Action Aid, which published the report ahead of next week's summit in New York to discuss progress on the millennium development goals, says hunger is costing the world's poorest nations $290 billion a year- more than 10 times the estimated amount needed to meet the goal of halving global hungry by 2015.

India now has worse rates of malnutrition than sub-Saharan Africa; 43.5 % of children under five are underweight and India ranks below Sudan and Zimbabwe in the Global Hunger Index. Even without last year's disastrous monsoon and the ensuring drought and crop failures, hunger was on the increase.

The government has promised a new food security bill to provide cheap food for the poor, but progress has been slow. The reality is that a country desperate to take its place at the world's top table is unwilling to commit to feeding its own population.

Last month the country's Supreme Court castigated the government for allowing 67000 tonnes of badly stored grain to rot- enough to feed 190000 people for a month- and ordered it to distribute 17.8 m tonnes in imminent danger of rotting. 

India's Prime Minister protested, saying that the court has crossed the line into policy making and warning that distributing free food to the 37% of the population living BPL will destroy any incentives for the farmers to produce. The court stood firm. It was an order, not a suggestion, the judges said.

According to Action Aid, global hunger in 2009 was at the same level as in 1990. The charity urged developed countries to make good on $14 billion pledge to fight hunger, announced at last year's G8 summit in Italy.

 

Q. Which of the following statements would help explain the Prime Minister's argument against the Supreme Court order?  

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 22

The argument that the PM puts forth is that distributing free food will destroy any incentives the farmers will have to produce. This indicates an interference with the market economy and hence option b is the answer. Option a can be ruled out as there is no hint that farmers will bear the cost of distributing free grain. Option c cannot be inferred from the passage. Option d is incorrect as it does not help to understand why farmers would be demotivated to produce if the government decides to distribute grain free of cost.

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 23

Statements:

I. Javed's salary is 75% that of Vinod's salary.

II. Javed's salary is Rs 4500.

 

Q. Vinod's and Javed's salaries are in the proportion of4:3 respectively. What isVinod's salary?

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 23

Statement I is merely an interpretation ofthe information contained in the question.

However, Vinod's salary can be ascertained from II as follows: Let Vinod's and Javed's salaries be 4x and 3x respectively. Then, 3x = 4500 or x = 1500. Therefore Vinod's salary = 4x = Rs. 6000.

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 24

Your supervisor gets all his work done by you and takes all the credit himself. Your senior manager is selecting a team for assigning a prestigious project. Being a part of this project guarantees growth in the organization. He selects your supervisor and not you. You feel that you deserved to be selected as you are more capable than your supervisor. You will  

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 24

A mail that draws attention to your achievements and performance in the past can persuade the manager to consider you for the project. Thus, it makes sense to directly approach your senior manager. Furthermore, a written communication is preferred over a verbal one. Option b, talking to your supervisor to make him aware of your dissatisfaction and plead with him to suggest your name would be the next best option. Since your supervisor knows of your capabilities his support would help your attempt to be selected as a part of the team. Quitting the job is not a wise option. Talking ill about your supervisor is not recommendable as you might not be able to prove the facts. Also his not being a part of the team does not assure your selection in the team.

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 25

                                                                                     Passage 2

How is India's middle class culture being changed and affected? Let us have a look at what is happening. First the numbers, independent India did not count its population along the lines of caste, and it required special surveys, like that of the Mandal Commission, to identify the size of peasant groupings. The number was revealed to be over 50% of the population. The British census before independence told us that the Brahmin population was about 6%, though the community's power and projection in urban India was disproportionate.

Three small castes, all put together about 10% of the population, dominated the urban middle classes. Brahmin, Baniya and Kayastha. What most urban Indians know as middle class culture is actually the culture of these 3 communities.

The second most important thing we must consider is the quality and texture of literacy. India was only 5% literate at the turn of the 20th century, and in the last 20 years the direction of urban middle class literacy is towards English. Increasingly, families speak English even at home and most middle class Indians do not read in their mother tongue. We are not referring here to the ability to read, which they have picked up at school. They can speak in the mother tongue, if it is peppered with the English words which have become indispensable. We mean regular reading of literature or entertainment in the mother tongue.

This has produced a unique community. There is no parallel to India of a nation whose middle class is trained to think and approach life in a foreign language, one they have not mastered. India's elite occupy a minimal space; it is emotionally Hindi and intellectually English. One reason India produces so little literature is that India's middle class does not own any language properly. The knowledge of English has come to them through stock phrases because the quality of teaching is poor. Even half literate Americans speak better, cleaner and more precise English than educated Indians. And on the mother-tongue side, the loss of language has resulted in the erosion of India's high culture, its classical inheritance.

 

Q. The author makes a reference to regular reading of literature in the mother tongue. What does he imply by this?  

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 25

Refer to the second paragraph. The author mentions literacy in terms of quality and texture. To explain this point further he makes a mention of regular reading of literature. Option b is correct as it is the point that the author is trying to make in the paragraph. Option a is incorrect as the author does not make such a suggestion in the passage. Options c and d cannot be inferred from the passage.

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 26

Statements:

I. Sharad is younger than Madan.

II. Arvind is younger than Kamal. 

 

Q. Madan is elder than Kamal and Sharad is younger than Arvind. Who among them is the youngest?

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 26

As given, we have: M > K,A > S.

From II, K > A. Thus, we have: M > K > A > S.

So, Sharad is the youngest. From I, M > S. Thus, we have: M > K > A > S or M > A >K > S or M > A > S > K.

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 27

Just as one must learn the art of killing in the training for violence, so one must learn the art of dying in the training for non-violence. Violence does not mean emancipation from fear, but discovering the means of combating the cause of fear. Non-violence, on the other hand, has no cause for fear. The votary of non-violence has to cultivate the capacity for sacrifice of the highest type in order to be free from fear. He recks not if he should lose his hand, his wealth, his life. He who has not overcome all fear cannot practice ahimsa to perfection. The votary of ahimsa has only one fear that is of god. He who seeks refuge in god ought to have a glimpse of the atma that transcends the body; and the moment one has a glimpse of the imperishable Atma one sheds the love of the perishable body. Training in violence is thus diametrically opposed to training in violence.
