UPSC CSE Prelims Paper 2 Practice Test - 7 - Question 1

Directions (Q.1-10) for the following 10 items:

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

                                                                                     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. Which of the following can be inferred from the passage?

Detailed Solution for UPSC CSE Prelims Paper 2 Practice Test - 7 - Question 1

Option a cannot be inferred as the passage only states that the loss of $150 billion is a 25 percent jump from the previous year. There is no information available to conclude that it is the highest ever. Option b is also incorrect as the passage states ‘Are these extreme events...answer is probably both.' Thus, the author does not attribute the climate change only to human activities. Option c is incorrect as it is a broad generalization and the scope of the passage is narrow. It would be inappropriate to draw option c as a conclusion. Option d can be inferred from the second paragraph ‘In the USA last year..........nine such disasters in 2008'.

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

Detailed Solution for UPSC CSE Prelims Paper 2 Practice Test - 7 - Question 2

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.

UPSC CSE Prelims Paper 2 Practice Test - 7 - Question 3

                                                                                   Passage 1

Consider the following statements:

1. Natural weather cycles can be the reason for instances of extreme weather

2. Bangkok, Thailand is the biggest producer of computer hard drives in the world With reference to the passage, which of the following statements is/are valid

Detailed Solution for UPSC CSE Prelims Paper 2 Practice Test - 7 - Question 3

Statement 1 is correct as the last paragraph mentions ‘The primary forces....EI Nino and La Nina.' Statement 2 is not correct as based on the information given in the passage one cannot conclusively infer that Bangkok, Thailand is the biggest producer of computer hard drives in the world. Thus option a is correct.

UPSC CSE Prelims Paper 2 Practice Test - 7 - Question 4

                                                                                    Passage 1

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.

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.

 

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 UPSC CSE Prelims Paper 2 Practice Test - 7 - Question 4

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.

UPSC CSE Prelims Paper 2 Practice Test - 7 - Question 5

                                                                                   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 UPSC CSE Prelims Paper 2 Practice Test - 7 - Question 5

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

UPSC CSE Prelims Paper 2 Practice Test - 7 - Question 6

                                                                                    Passage 2

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 UPSC CSE Prelims Paper 2 Practice Test - 7 - Question 6

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.

UPSC CSE Prelims Paper 2 Practice Test - 7 - Question 7

                                                                                    Passage 2

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. MGNREGS has not done much to increase land productivity

2. Transformation of rural labour relations influences production decisions of farmers With reference to the passage, which of the following statements is/are valid?

Detailed Solution for UPSC CSE Prelims Paper 2 Practice Test - 7 - Question 7

The sentence ‘MGNREGS has helped....in rainfed areas' says that MGNREGS can do much more to increase land productivity. This does not tell us whether MGNREGS has done much to increase land productivity or not. The second last sentence of the passage tells that the transformation in rural labour relations is bound to affect the production decisions of farmers. Hence it can be said that the transformation of the rural labour relations influences the production decisions of the farmers

UPSC CSE Prelims Paper 2 Practice Test - 7 - Question 8

                                                                                   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 UPSC CSE Prelims Paper 2 Practice Test - 7 - Question 8

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.

UPSC CSE Prelims Paper 2 Practice Test - 7 - Question 9

                                                                                   Passage - 3

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. Earth scientists will come up with cost effective extraction technologies.

2. Promotion of the extraction of hi-tech minerals is required. With reference to the passage, which of the following statements is/are valid?  

Detailed Solution for UPSC CSE Prelims Paper 2 Practice Test - 7 - Question 9

The passage tells that ‘emerging demand for hi-tech minerals only calls for earth scientists anticipating demand and exploring and extracting these minerals with cost effective and environment friendly extraction technologies'. This does not mean that the scientists will definitely come up with the cost effective exploration technologies. The sentence ‘Agencies of both....of these minerals' makes it clear that promotion for the extraction of hi-tech minerals is required. Thus option b is correct

UPSC CSE Prelims Paper 2 Practice Test - 7 - Question 10

                                                                                   Passage - 3

Q. Consider the following statements:

1. Concept oriented studies are an important component of mineral surveys and exploration programs.

2. The area of mineral exploration can acquire higher capability through concerted action plans. With reference to the passage, which of the following assumptions is/are valid?

Detailed Solution for UPSC CSE Prelims Paper 2 Practice Test - 7 - Question 10

The line ‘The mineral surveys........ state of the art technologies' only tells us that mineral surveys etc. have to be targeted to take up the concept oriented studies. On this basis, one cannot say that the concept oriented studies are a component of mineral surveys and exploration programs. The line ‘Concerted action plans need.... exploration and development' makes it quite clear that the area of mineral extraction can acquire higher capability through concerted action plans. Thus option b is correct.
