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 1

Consider the following statements:

1. Both heavy rains and droughts have affected the world

2. Events in the Pacific can cause changes in the weather of areas like East Africa 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

The passage mentions the havoc wreaked by both the droughts and heavy rains. Thus statement 1 is valid. The passage also mentions ‘Scientists have learned a lot....affects weather worldwide' and also ‘In a La Nina.......like East Africa.' Thus statement 2 is also valid and hence option c is correct.

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 3

                                                                                   Passage 2

Focus should be on raising land productivity and water use efficiency. State specific strategies are needed. Dry areas need to focus on livestock. Most importantly, markets must be reformed. An important beginning has been made by granting statutory status to warehouse receipts. However, the real benefits from this measure can accrue only when the appropriate warehouse infrastructure and supporting backward linkages have been created and a nationwide trading platform has been put in place. Consideration should be given to extending infrastructure status to a wider range of agricultural market facilities in the same manner as for warehouses. States must modify the Essential Commodities Act (ECA) and the APMC Act (perhaps exclude horticulture and perishables entirely from the ambit of APMC), rebuild the extension system, increase the involvement of the private sector in marketing, and also facilitate leasing in/out of land by farmers. State agricultural universities and extension networks are in a bad shape and need strengthening.

MGNREGS has helped generate employment and income in rural areas but it can do much more to increase land productivity, particularly in rainfed areas. In addition, MGNREGS has transformed rural labour relations, which is bound to affect the production decisions of farmers, both in terms of crops as well as technologies. The agricultural support systems must facilitate this transition, which requires greater flexibility and responsiveness.

 

Q. Consider the following statements:

1. Currently the land productivity is quite low.

2. Appropriate warehouse infrastructure is potentially beneficial.

As per the above passage, which of the given statements is/are valid?

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 3

The passage only talks of raising the land productivity, based on this information one cannot say that currently the land productivity is low. It is possible that there is a need for raising the productivity for future needs. The

sentence ‘However the real benefits........ been put in place.' tells that appropriate warehouse infrastructure is

potentially beneficial. Thus option b is correct

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 4

The agricultural support systems must facilitate this transition, which requires greater flexibility and responsiveness.

 

Q. Consider the following assumptions:

1. State agricultural universities have a room for improvement.

2. The current problem can be solved through market reforms alone.

With reference to the passage, which of the following assumptions is/are valid?

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 4

The last sentence of the first paragraph tells that the state universities are in a bad shape; this means that they have room for improvement. The passage mentions the need for market reforms as one of the vital things to be done but it is nowhere mentioned that market reforms alone can solve the problem at hand.

OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 5

                                                                                   Passage - 1

All this time, Abe had kept on steadily with his reading whenever he had time, especially in the long winter evenings when he could read by the firelight. Lamps and candles were luxuries no settler could afford, but the wood was plentiful and it was easy to heap the fire high and make a splendid blaze.

He was careful, too, not to forget his writing, and he practiced writing his own name in the snow with a charred stick on slabs of wood. His father was not always pleased to find every smooth surface of the house scrawled over with black marks, but he had a great respect for learning and when he found that Abe was teaching himself to write, he was quite proud of the boy. When spring came around and they were working together in the fields, Abe took a stick and began writing his name with great care in the soft earth.

 

Q. Abe used to

1. work with his father in the fields sometimes

2. write his name in the snow, on wood and in the earth

Choose the correct option using the codes given below:

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

                                                                                   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 7

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.

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

                                                                                   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.

Q. Which of the following is/ are correct?

1. Those who grow up as scientists are usually not exposed to books and museums in their childhood

2. Only those who become scientists remember their childhood experiences of books and museums

Choose the correct option using the codes given below:

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

The passage does mention that "Many children are exposed to books and museums but a few become scientists". From this statement, we can not infer either 1 or 2.

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

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 9

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 10

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 10

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 11

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. How is T related to K?

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

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

You head the commercial aviation arm of the government, which is not doing well financially. The reason for this is the laid back attitude of the employees of the company. The employees hardly bother about providing the services to the customer. You have been asked to turn around the organization and make it possible. You will-   

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

The actual problem in this situation is the laidback attitude of the employees. Only bringing a change in the attitude of the employees can solve this problem and option a aptly caters to this need in the long term and hence is the best option. Option b is the next best option as even though it cannot be considered a long term solution it will communicate to the employees your resolve to fix matters. Option d is not correct as it is impracticable of you to ask the government to cancel the license of other aviation companies for no fault of theirs. Option c is incorrect as any financial help will not help in the turn around of the organization until the employees have the right attitude to run the organization.

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

You will   

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

Option c is the best choice as initiating an inquiry is the procedural way to deal with the case. Option b is the next best choice and could be in a way be part of the inquiry mentioned in option c. Moreover, it also prevents the possible tampering of evidence by the accused but it would require a search warrant for raiding the place and this will take you some time to obtain, hence, this cannot be done immediately. Option a is incorrect as you are not a police officer and arresting the person merely based on the media reports will be inappropriate. Options d is incorrect as this would mean that you are trying to shun the responsibility at hand and compromising on your ethics.

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

You are working as a supply supervisor in a leading oil company in the public sector.

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

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 17

Statements:

I. Gagan, Vimal and Kunal are all of the same age.

II. Total age of Vimal, Kunal and Anil is 32 years and Anil is as old as Vimal and Kunal together.

 

Q. What is Gagan's age?  

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

As given in I and II, we have: G = V=K,V+K + A = 32 and A = V+K.

Putting V+K = A in V+K + A = 32, we have: 2A = 32 or A= 16.

Thus, V + K=16 and V=K. So, V=K=8. Thus, G = 8

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

Directions (Q. 65-71) for the following items: 

Read the following two passages and answer the items that follow these passages. Your answers to these items should be based on these passages only.

                                                                                    Passage 1

The NAC proposals go against its earlier proposal of experimenting with universal entitlements in the poorest 150 districts of the country - a retrograde step for a country where half of the population is malnourished. In the final proposals, even this minimum effort to experiment with universalization was given up. The issue is why the NAC went against such universalization.

A universal PDS is not only the best possible option from the perspective of a rights based approach, it is also far more realistic in its commitment to ensure food security for the poor. Universalization would also be in line with the larger agenda of the UPA government of changing the architecture of the social service programs to make them more inclusive.

Targeting is inherently problematic. The BPL census, which is the primary means of targeting public services and subsidies to the poor, has failed to serve the purpose. The process of targeting is not only administratively costly but also discriminatory to the poor; limiting food security to BPL necessarily involves the exclusion of families who are very similar to other families that have been included. Historically, limiting food security to BPL families has severely impaired the effective access of food for poor families. Large numbers of poor families did not have BPL cards, even when they had cards, access to PDS was not automatic and, even ifthey had access to the PDS, they did not receive the full entitlement of food. But does it really mean that universalization is not feasible? Do we have enough foodgrains for a universal system?

The total requirement of a Universal PDS is 96.60 million tonnes if the entire population lifts its foodgrain quota. However, there will be some sections of the population who will not take their quota of foodgrain. This could be because they are well off and therefore do not need the ration food. It could also be a matter of taste and preference and they may not like the PDS foodgrain which is generally of inferior quality. These will largely be the rich and well off in urban areas.

 

Q. It can be inferred from the aim of the passage is to  

Detailed Solution for OPSC OAS Prelims Paper 2 Mock Test - 10 - Question 18

The passage starts with the criticism of the NAC's proposal and then moves on, in the next few photographs, to discuss the possible options in improvement. Option c is the answer. Option a is incorrect as though the author extols the virtue of a universal PDS, it is one of the options to better the situation. Option b is incorrect as the passage is also concerned about these families that have not been taken into account by the poverty line. Option d is incorrect as the passage by itself cannot overturn the NAC's proposals nor does it seek to do so.

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

Q. Limited food security to BPL families is not a feasible option. Why?  

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

Refer to the first few lines of the third paragraph. The first sentence reveals that limiting food security to BPL families leaves out other deserving families. The second sentence discusses why limiting food security is not feasible- "it impairs the effective access to food for poor families". Option a is the answer. Option b can be ruled out because in the passage, there is no mention of the middlemen in the PDS system. Option c is incorrect as the author never links the issue in this option with limiting food security to BPL families. Option d, while looks like the correct option, stands incorrect due to its general nature.

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

                                                                                     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. Which of the following options would help one understand the author's argument that the loss of language has resulted in the erosion of India's culture?    

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

The last paragraph provides an answer to this question. Option a is incorrect as it does not help explain why there is an erosion of the Indian culture. Option b is incorrect as it is vague- the passage makes a reference to the half-literate Americans. This option does not link with the mother tongue and the Indian culture. Option c is the answer as it provides a reason as to why the loss of language has also resulted in the erosion of India's culture. Option d is incorrect as it only restates the question and does not answer it.
