General Studies Paper – II

1. Answer any two of the following in about 250 words each:      20×2= 40

(a) List the Central Asian Republics and identify those of particular strategic and economic importance to India. Examine the opportunities and bottlenecks in enhancing relations with these countries.


Central Asian Republics include Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan, Although all of them are important for India from the perspective of trade, security, energy security, civilisational link, but the ones particularly important are Kazakhstan, Turkmenistan and Tajikistan.

Kazakhstan is one of the fastest growing economies of Central Asia and a politically stable nation. India has signed civil nuclear agreement with Kazakhstan and agreed to give India a foothold in the oil rich Caspian through Satapayev block. Central Asian republics are important to India for its energy security (vast reserves of oil, gas and radioactive material), a potential market for its growing trade, strategically vital to safeguard India’s interest in Central Asia, West Asia and Africa. TAPI gas pipeline agreement signed recently involving Turkmenistan promises to address some of India’s energy needs through supply of natural gas. Central Asian Republic are also potential markets for export of Indian pharmaceuticals, IT services, entertainment services etc.

These nation are also part of regional groupings like SCO which will play crucial role in regional stability and prosperity in Asia and hence in the world.

On the flip side of it, some of these nations are not politically stable, lack vibrant democracy, and are marred by ethnic clashes which make it difficult for the businesses to operate. Lack of infrastructure and land connectivity also places obstacles in the smooth business activity. The same product that would take more than a month to reach these nations from India can be obtained within a week from China, Turkey or Europe. Terrorism emanating from the Central Asian region like from Fergana valley is another area of concern and challenge for India.
(b) Critically examine the security and strategic implications of the so-called ‘string of pearls’ theory for India.


String of pearls theory refers to China building deep water ports in the Indian Ocean like Gwadar (Pakistan), Hambantota (Sri Lanka), Sittwe(Mayanmar), Chittagong (Bangladesh)  as a part of the strategy to encircle India. China denies this and claims that it is not directed against any nation. It is rather for securing its energy supplies and sea routes for its trade.

Several western analysts including some Indian Defence analyst think otherwise and claim that it is part of China’s strategy to contain India in the event of any future conflict. India is surrounded by sea from three sides and a naval dominance of China or any other nation in Indian Ocean is certainly a security concern for India. String of pearls makes China India’s maritime neighbour and give the opportunity to China to have a two front situation against India in case of a conflict.

Strategically China’s growing indulgence with India’s neighbours like Sri Lanka or Bangladesh through these ports gives China an extra lever to use against India. It can be used both as soft and a hard power to gain strategic depth inside India’s neighbourhood.
India’s rise on the world stage is guided mostly by its economic might in terms of its rising GDP and share in world trade which depends largely on the sea routes through which the trade is conducted. Any dominance on the sea routes can be used against India’s growth and thus requires India to take cognizance of the String of Pearls strategy by china.  

(c) “Compared to the South Asian Trade Area (SAFTA), the Bay of Bengal Initiative for Multisectoral Technical and Economic Cooperation Free Trade Area (BIMSTEC FTA) seems to be more promising.” Critically evaluate.


BIMSTEC was initiated with the goal to combine the 'Look West' policy of Thailand and ASEAN with the 'Look East' policy of India and South Asia. So it could be explained that BIMSTEC is a link between ASEAN and SAARC. BIMSTEC provides a unique link between South Asia and Southeast Asia bringing together 1.3 billion people - 21 percent of the world population.

Compared to south Asian free trade area (SAFTA), the BIMSTEC FTA seems to be more promising. A deeper economic integration process within South Asian Association of Regional Cooperation (SAARC) sometime suffers because of political tension between India and Pakistan. Such things are less likely to happen in case of BIMSTEC. It is believed that negotiation under the BIMSTEC umbrella will be easier than under SAFTA because all the BIMSTEC members are purely guided by economic interests rather than by political interests. Many countries in SAFTA have less favorable geographical location in terms of being land locked and thus have adverse affect on trade as compared to BIMSTEC nations. BIMSTEC being a link between South Asia and South East Asia also opens up vast opportunities for trade as compared to SAFTA which is limited to mainly South Asia.

When compared in terms of their economic structure, namely, value addition of services, industry, and agriculture sector, to gross domestic product (GDP), BIMSTEC nations have many similarities. Except in case of Thailand, the industrial sector constitutes roughly a fourth of GDP in all countries. All these economies are predominantly associated with service related activities. Although majority of the population still lives in rural areas, all of these nations are becoming increasingly urbanised. Geographical proximity along with similar economic profile indicates complementarities in consumption, production, and trading pattern. All these factors make BIMSTEC FTA more promising.

2. Answer any three of the following in about 150 words each:     15×3=36

(a) Subsequent to the Nuclear Supplier Group (NSG) waiver in 2008, what are the agreements on nuclear energy that India has signed with different countries?


Subsequent to NSG waiver India has signed Civil Nuclear Cooperation with nine nations and South Korea is the latest in the list. The NSG waiver ended nuclear apartheid of almost three decades for India where world declined to share any nuclear technology and resources with India even for non military purposes.

India has also incorporated enrichment and reprocessing agreements with several nations like Russia and France after the NSG waiver. Countries have guaranteed fuel supply to Indian nuclear reactors which were running much below their capacity due to lack of nuclear fuel.

India has also passed legislation on nuclear liabilities and is progressing towards ratifying Convention for Supplementary Convention which will bring India in line with the international regime and facilitate nuclear suppliers of other nations to do business with India.

(b) Trace the progress of India’s efforts for a joint counter-terrorism strategy with China. What are the likely implications of the recent Xinjiang violence on these efforts?


India and China have completed two rounds of joint anti terrorism exercise in 2007 and 2008. Although the symbolic importance of these exercises is immense, both countries could explore cooperation in preventive measures particularly intelligence sharing; and hotline for critical situations to tackle the menace of terrorism. The two sides could consider maximizing their cooperation in the field of counter-terrorism and further consolidating strategic partnership between the two.

China’s Xinjiang problem is connected with the network of cross border and transnational terrorism. Xinjiang is a case in point of the ethno-religious separatist problem in the Xinjiang region.

Even after having such immense opportunities, India and China defense cooperation has been stalled due Chinese policy of stapled visa or denial of visa for Indian army officers from Jammu and Kashmir region and the state of Arunachal Pradesh.

(c) Bring out the importance of the Small and Medium Enterprises Expo and Conference held in Dubai last year for Indian business.


The 2010 SME Conference theme was Meet, discuss, start. Last year’s conference was designed to provide information and assistance to all sizes of small businesses, as well as to those from the government who work with them. The conference created opportunities for small business owners and entrepreneurs to network, build alliances, and learn about new products, services and trends. Relevant educational presentations provided participants with new strategies and tools that can be put into action.

The conference was important for Indian business because of following reasons

• Opportunities for SME
• Strategies to boost the business environment for SMEs
• Investments and financing SME growth
• Banking and financial service innovations for SMEs
• Technologies that can help SME growth
• Women Entrepreneur

Small and Medium Enterprises Expo and Conference, offered great platform to small units to promote their brands, products and services, as well as to explore business opportunities in the Middle East and North African markets.

Besides giving a major impetus to networking activities with other visiting countries such as Pakistan, Mauritius, Nigeria and Vietnam, the event offered Indian SMEs the opportunity to acquaint themselves with the latest technologies in their industries and form alliances with international clients. Indian SMEs from sectors such as plastic, petrochemicals, garments and textiles, and art and handicrafts, among others gained from the participation at the expo.

(d) What are the salient features of the political and economic relationship between India and South Africa?


South Africa has emerged as an important ally for India in recent times. Apart from having civilisational links and India’s close support during the apartheid movement and Mahatma Gandhi’s proximity with the cause South Africa is also a symbol of India’s engagement with the African people and society.

India and South Africa are part of IBSA and BRICS. IBSA represents south-south alliance while BRICS is concerned more with the economic cooperation among the member states. India and South Africa have given coordinated response in G20 and WTO. South Africa is an important destination for investment by the Inidan Business Community and a joint CEOs forum has been set up between the two nations to deepen economic cooperation and raise the level of bilateral trade.

The two nations have demanded reforms of the international institutions, given coordinated responses in the climate change negotiations with the developed nations. They coordinated and put a joint stand on the issue of Syria which provided a third alternative or a middle path in dealing with such issues of international intervention. The two nations also have a shared understanding of Iran’s nuclear issue.
3. Answer either of the following in about 250 words:    20

(a) “The causes and implications of the Jasmine Revolution and its spread are as much economic in nature as they are political.” Critically evaluate.


The region of West Asia and North Africa is in a state of flux and going through a turbulent phase. The ripples that started in Tunisia from Jasmine revolution has spread far and wide. Many regimes like in Egypt and Libya have fallen since then while some have been truly shaken like in Syria, Behrain and Yemen.

The region shares some common economic and political characteristics that have resulted in this. These regimes have been more or less dictatorial in nature, giving minimum or no political liberties to its citizens. The freedom of speech, expression and movement has been restricted in past with no credible democracy. Elections were often rigged and constitutions manipulated to suit the ruling elite. The growing reach of media and social networking sites on the other hand opened the window for their people to peep into the outside free world. This raised their expectations from their own rulers and also provided a platform to organise protests against the regimes. Underlying ethnic and sect tensions against the regimes have also added fuel to the fire.

Economic reasons like high rate of unemployment among youth as in case of Tunisia, and low per capita income have also resulted in these revolts. The rulers in these nations have indulged in lavish life style and amassed treasures while the fellow citizens were starving and struggling with poor education, health and public utilities system. None of these nations had any proper higher education system which could ensure respectable jobs to its youth. Many countries like Bahrain and Saudi Arabia have distributed cash and benefits among its citizens since the start of Jasmine revolution but that does not address the systemic reforms that the people these nations are demanding.
(b) In the context of the ‘Euro-zone’ debt crisis, examine the proposed ‘six-pack’ solution. Do you think that this has a better chance of success than the earlier stability and growth pact?


The six pack solution has been proposed for Euro Zone debt crisis which threatens to drag the world economy along with it into yet another full blown crisis. It is a set of legislative measures that gives European Commission the ability to impose sanctions on the eurozone countries that fail to control their debt and deficit. The rules are designed to prevent any future debt crisis of the present nature and thus give more sanctioning power to European Commission.

The European parliament will have the right to call finance ministers from countries that have been warned to hearings, while the European semester provides for the annual assessment of national budgets. Falsified debt and deficit statistics can lead to a fine of 0.2 per cent of gross domestic product. And countries will be obliged to act pre-emptively to maintain the health of economies threatened by imbalances such as a housing-bubble.

The legislation would discourage member states from evading their responsibilities to each other to ensure the stability of the eurozone. The rules would provide for enhanced monitoring and surveillance of imbalances like unemployment, credit growth and housing bubble etc. This would also give right signals to the financial markets about the seriousness of the EU and its resolve to handle any future debt crisis.

4. Answer any four of the following in about 150 words each:     12×4=48

(a) “As regards the increasing rates of melting of Arctic Sea ice, the interests of the Arctic Council nations may not coincide with those of the wider world”. Explain.


The climate change has increased the rate of melting of the Arctic Sea Ice. This has increased the access of earlier hidden oil and gas resources. Many Arctic countries like Russia, Denmark, Canada and Iceland have rushed to claim their sovereignty over these resources. They see the climate change as an opportunity to exploit these hidden resources. They also provide new opportunities for fishing and shipping. 

Wider world on the other hand is concerned about the increasing rate of melting of Arctic Ice as this can threaten existence of some species, disturb the water and ocean cycle, adversely affect global average temperature, and can also lead to loosing climate history stored in these ice sheets. This is a ecologically sensitive area and highly unregulated thus causes concerns for the world at large.
(b) Is there still a role for the concept of balance of power in contemporary international politics? Discuss.


The balance of power in the contemporary international politics can be used not only in terms of one super power balancing the other or regional balance of power but also the balance between hard and soft power. The disintegration of USSR tilted the balance of power in favour of America but economic rise of China has started to threaten the numero uno position of USA.

Several example of balance of power in international politics is seen. USA uses Israel as a tool to balance power in West Asia. NAM during the cold war era was used by developing countries to balance the relationship between two superpowers. The doctrine that neighbour’s neighbour is a friend is seen in several situations like China having all weather friendship with Pakistan to balance India. Chinese allege that USA is using its neighbours to contain the rise of China.

The growing economic prowess of emerging economies like India, China, Brazil and South Africa is being used in international forums like G20 or WTO to balance the developed nations. Thus the concept is very much alive even though it might have weakened a bit in the interconnected globalized world with supra national organisations like United Nations playing a key role in international politics.      

(c) “Strategic interests seem to be replacing commercial interests for the host country with regard to Cam Ranh bay.” Amplify.


Vietnam opened its Cam Ranh Bay after eight years of its closure. The bay is in the northeast of Ho Chi Minh City. It is one of the best deepwater shelters in Southeast Asia. Ships can stop here for refuelling or repair. It enjoys a geo strategic significance as it is located near to key shipping lanes in the South China Sea. China’s aggressive policy in the South China Sea also led to this decision by Vietnam.

The Bay has been strategically crucial for great powers like Russia, Japan, France and USA in the history. Vietnam had not opened it after Russian withdrawal in 2002 but the recent claims by China seems to have led Vietnam to take this step. Opening of the Bay for the navies of many nations will indirectly strengthen Vietnam’s claim and right in the South China Sea and weaken Chinese position. 

(d) To what extent has the withdrawal of al-Shabab from Mogadishu given peace a real chance in Somalia? Assess.


Al-Shabab has withdrawn from most parts of the capital of Somalia but its fighters still control some areas, including Deynile. The Islamist group withdrew after a government offensive to retake the city and clear the way for foreign aid destined for drought and famine victims. African Union troops has helped push back the rebels.

Al-Shabab once controlled nearly all of Mogadishu and still controls large swaths of central and southern Somalia. The group has tightly controlled the delivery of aid to famine victims in its territory, and has banned access for many international aid agencies. Thus its withdrawal provides real opportunity for peace but it also depends on how this opportunity is utilised by the Somalis government.

Al-Shabab on the other hand has claimed that the retreat was a strategic move and it will remain nearby and continue its effort to topple the United Nations-backed government.

(e) On a Formula-one (F-1) racing car track, information to drivers is generally signalled through the standardized use of flags of different colours. Describe the meaning associated with any six of the flags listed below:

(i) White Flag


When the white flag is waved by the race marshals, it means the drivers should immediately slow down, as it indicates the presence of a safety car, ambulance or towing truck ahead, on the track. In this situation, overtaking is strictly prohibited.

(ii) Black Flag


Once a race marshal waves the black flag and it attaches the race number to the car to it that means the driver is disqualified for the ongoing race. After seeing the black flag, a driver must enter the pits within the next lap and report immediately to the Clerk of the Course.

(iii) Yellow Flag


Indicates danger ahead and overtaking is prohibited. A single waved yellow flag means slow down, a double waved yellow warns that the driver must be prepared to stop if necessary.

(iv) Blue Flag


Shown to a driver to indicate that a faster car is behind him and trying to overtake. Shown both to lapped cars and those racing. A lapped car must allow the faster car past after seeing a maximum of three blue flags or risk being penalised.

(v) Black and White Flag divided diagonally


Shown with car number to indicate a warning for unsportsmanlike behaviour. A black flag may follow if the driver takes no heed of the warning.

(vi) Chequered Flag


This shows that the race has ended. Shown first to the winner, and then to every car to cross the line behind them.

(vii) Yellow and Red Striped Flag


The track is slippery. This usually warns of oil or water on the track.

5. Comment on any thirteen of the following in about 50 words each:    5×13=65

(a) International Year of Chemistry


The United Nations declared 2011 to be the International Year of Chemistry. The year 2011 marks the 100th anniversary of the founding of the International Association of Chemical Societies, as well as the year Madame Marie Curie won the Nobel Prize – which celebrates the contributions of women to science. The Year hopes to promote the appreciation of chemistry in meeting world needs and the future development of chemistry.

(b) The scourge of e-waste


e-waste constitutes of used, obsolete, and end of life cycle electronics product which if disposed in an unscientific manner can lead to pollution of air, water and soil. Acid bath, land fill and burning are used for the disposal of e-waste leading to pollution through heavy metals (like cadmium, mercury, and nickel) poly vinyl chloride and poly chlorinated biphenyl. e-waste is from developed countries is being dumped to developing countries causing large scale health hazards.       

(c) Designer poultry eggs


Designer eggs are for beauty conscious consumers, as well as persons affected with diabetes and heart-disease. It will be bacteria-free, rich in protein and high on calorific value. The designer eggs are produced through a scientific method adopted for nurturing the layer with the right feed so that they lay high quality eggs. The composition of the feed leads to the desired composition of the eggs.

(d) INSPIRE programme of the Department of Science and Technology


Innovation in Science Pursuit for Inspired Research (INSPIRE)" is an innovative programme sponsored and managed by the Department of Science & Technology for attraction of talent to Science. The basic objective of INSPIRE is to communicate to the youth of the country the excitements of creative pursuit of science, attract talent to the study of science at an early age and thus build the required critical human resource pool for strengthening and expanding the Science & Technology system and R&D base.

(e) The Kessler syndrome with reference to space debris


The Kessler Syndrome is a future scenario when the amount of space junk reaches a high enough density that each collision will produce sufficient fragments that generate a slow cascade effect; producing more collisions and debris, eventually causing our species to become incapable of launching space craft. It was first proposed in 1978 by Donald J. Kessler when debris that accumulates in space is increasing faster than what debris falls out of orbit and burns up.

(f) Omega-3 fatty acids in our food


Omega-3 fatty acids are polyunsaturated fats found naturally in oily fish, nuts, seeds, and leafy green vegetables. Omega-3 fatty acids are thought to protect against heart disease, inflammation, and certain types of cancer, diabetes, Alzheimer’s disease, and macular degeneration (a leading cause of vision loss). Omega-3 fatty acids are critical for proper brain development and neurological function in developing babies, too.

(g) Difference between ‘spin-drying’ and ‘tumble-drying’ technology with reference to drying of washed clothes


Spin drying technology for drying washed clothes saves time as the high speed and RPM (revolutions per minute) allows the clothes to get rid of water quickly due to centrifugal force. Tumble drying technology on the other hand works mainly on the heated air being passed through the clothes to dry them up. Heat and not spinning speed is used to dry the clothes through this technology.

(h) The admonishing population of vultures


The vulture population has been declining which was a cause of concern. Use of diclofenac with the cattle population is partly responsible for this decline. Bombay Natural History Society has taken up conservation and awareness efforts which have positively impacted the vulture population. Vulture breeding centres are set up in Pinjore(Haryana), Rani forest (Assam) to arrest the declining population. The slender billed, white backed vultures are among the endangered species.

(i) ‘Arsenic-bug’ and the significance of its discovery


NASA-supported researchers have discovered the first known microorganism on Earth able to thrive and reproduce using the toxic chemical arsenic. The microorganism, which lives in California's Mono Lake, substitutes arsenic for phosphorus in the backbone of its DNA and other cellular components. Carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur are the six basic building blocks of all known forms of life on Earth. This finding will alter biology textbooks and expand the scope of the search for life beyond Earth.

(j) F-22 ‘Raptor’ aircraft


Developed by Lockheed Martin/Boeing, the F-22A Raptor is a supersonic, dual-engine fighter jet. The F-22 is designed for stealth, supercruise speed and super-agility.

It is a fifth generation aircraft. . It has additional capabilities that include ground attack, electronic warfare, and signals intelligence roles. It lost the Indian bid to Eurofighter and French Rafale recently.

(k) ‘Concentrated’ solar energy and’ photovoltaic’ solar energy


Concentrating solar power (CSP) technologies use mirrors to reflect and concentrate sunlight onto receivers that collect the solar energy and convert it to heat. This thermal energy can then be used to produce electricity via a steam turbine or heat engine driving a generator.Photovoltaic solar energy is method of converting solar energy into electrical energy using photovoltaic cells having semiconductors that exhibit photoelectric effects. Photovoltaic cells could use any of the semiconductors like silicon, selenium, gallium.

(l) Analog hybrid and IP systems in CCTV technology


Monitoring and surveillance applications were traditionally done by analog CCTV technology.  Analog CCTV systems are generally maintenance intensive, offer no remote accessibility, and are notoriously difficult to integrate with other systems. IP systems in CCTV technology gets rid of these obstacles.  It provides ease of use, advanced search capabilities, simultaneous record and playback, no image degradation, improved compression and storage, and integration potential. IP CCTV technology allows us to take advantage of  many new technologies like LAN, Broadband, VPN etc.

(m) Various applications of Kevlar


Originally developed as a replacement for steel in radial tires, Kevlar is now used in a wide range of applications.  The Kevlar tire technology has been applied to aeroplane, car, racing vehicle and truck tires. Some components of Kevlar are used in an array of rackets, such as tennis, badminton and squash rackets. Canoes and kayaks were also improved when Kevlar technology was applied there.

(n) Differences between Compact Disc (CD), Digital Versatile Disc (DVD) and Blu-ray Disc.


The Compact Disc is an optical disc used to store digital data. A DVD is an optical disc storage media format, developed by Philips, Sony, Toshiba, and Panasonic. DVDs offer higher storage capacity than Compact Discs while having the same dimensions.  Blu-ray Disc is an optical disc storage medium designed to supersede the DVD format. The plastic disc is 120 mm in diameter and 1.2 mm thick, the same size as DVDs and CDs. Blu-ray Discs contain 25 GB per layer. Blue ray gets its name from the blue laser used to read the data. It allows information to be stored at a greater density as compared to red laser being used in DVD.

(b) Success of international intervention of Cote d’Ivoire (Ivory Coast)


UN Security council had authorised the intervention in Cote d’Ivoire to end the standoff created by the Gbagbo who had refused to give power after defeat in Presidential elections.  UN peacekeeping French forces intervened and the intervention in Côte d'Ivoire worked. Within a week, former president Laurent Gbagbo, who had refused to accept defeat in an election and plunged his country into a steadily escalating spiral of violence and repression, was in custody, and within two weeks the majority of his forces had surrendered or rallied to the new President's side.

(c) Strategic adopted by Colombia to eliminate its drug cartels


Columbia has adopted a comprehensive strategy to eliminate drug cartels which involves reducing or eliminating corruption from the police force, judiciary and all the drug enforcement agencies.

(ii) Percentage of tubes whose life-time does not exceed 600 hours.

Percentage of tubes whose life-time does not exceed 600 hours = 29.5% from table below

(iii) Percentage of tubes whose life time is greater than or equal to 900 hours.

Percentage of tubes whose life time is greater than or equal to 900 hours = 19% from table below

Percentage of tubes whose life time is at least 500 but less than 1000 hours.

Percentage of tubes whose life time is at least 500 but less than 1000 hours = (Less than 1000 hours – Less than 500 hours) / 400 = (372 – 60)/ 400 = 312/400 = 78%

10. (a) A car travels 25 km at 25 kph, 25 km at 50 kph, and 25 km at 75 kph. Find the average speed of the car for the entire journey.


Distance in km Speed in kph Time taken  in hr = Distance/ Speed

25 25

25 50 0.50

25 75 0.33
Total 75
Average Speed in kph Total Distance/ Total Time 40.91

(b) The mean of 200 items was 50. Later on it was found that two items were wrongly read as 92 and 8 instead of 192 and 88. Find the correct mean.


Incorrect Total = 200*50 = 10000
Correct Total = 10000 + (192-92) + (88-8) = 10180
Correct Mean = 10180/ 200 = 50.9

(c) Students were asked how long it took them to walk to school on a particular morning. A cumulative frequency distribution was formed.

Time taken (minutes) c.f.
<5 28
<10 45
<15 81
<20 143
<25 280
<30 349
<35 374
<40 395
<45 400

(i) Draw a cumulative frequency curve.
(ii) Estimate how many students took less than 18 minutes.
(ii) 6% of students took x minutes or longer. Find x.    6

(d) An investor buys ` 1200 worth of shares in a company each month. During the first five months he bought the shares at a price of ` 10, ` 12, ` 15, ` 20 and ` 24 per share. After 5 months, what is the average price paid for the shares by him?    4


Number of shares in first month = 1200/10 = 120

Number of shares in second month = 1200/12 = 100

Number of shares in third month = 1200/15 = 80

Number of shares in fourth month = 1200/20 = 60

Number of shares in fifth month = 1200/24 = 50

Total number of shares = 410

Total money spent = 1200*5 = 6000

Average price for shares = 6000/ 410 = 14.6
