4 Why a higher growth can be reaped, despite a reduction in fixed capital (FC) formation inthe Indian economy?

FC is not directly correlated with economic growth rate.A.FC includes construction of dwellings as a sub-component which may notB.add to the productive capacity of the economy.Long-term growth can still be achieved if resources from FC are divertedC.towards consumption.All of the aboveD.

User Answer :Correct Answer : BAnswer Justification :

Explanation: Fixed capital formation (growth of productive infrastructure etc) isdirectly related with economic growth rate. So, option (a) is incorrect.

Option (c) is incorrect, as only short-term growth may be achieved if such diversionoccurs. In the long-term quality and quantity of infrastructure is a major determinantof economic growth.

Dwellings form more than 50% of the fixed capital formation in India.

Since dwellings do not add to the productive capacity of the economy, even if itsgrowth rate reduces, the economy can still grow. So, option (b) is correct.

Learning:Fixed capital is assets used in the productive process.

As per the new formula, there are changes both in the variables included/excluded aswell as the weights assigned to them.

Generally, the higher the capital formation of an economy, the faster an economycan grow its aggregate income. Increasing an economy's capital stock also increasesits capacity for production, which means an economy can produce more. Producingmore goods and services can lead to an increase in national income levels.

User Answer : DCorrect Answer : AAnswer Justification :

Explanation & Learning Before we explain it in words here, do watch this videohttp://study.com/academy/lesson/using-the-sun-stars-to-determine-latitude-longitude.html

Latitude is basically the angle of your place from the centre of the Earth (equatorialposition). Now, you can either find out this angle OR find out the angle of yourplace with respect to the North Pole. Finding the latter is easier as Pole Star isalways found vertically above the North Pole.

If you can find your place’s angle from the Pole star (North Pole), just subtract itfrom 90 degrees to arrive at your place’s latitude.

This cannot be done using a compass, as it merely shows North direction, and not

By absorbing the UV radiation and breaking down into oxygenB.By converting the harmful UV radiation into useful UV radiationC.By changing the frequency of UV radiation coming to earthD.

User Answer : DCorrect Answer : BAnswer Justification :

Explanation & Learning: The ozone layer acts as a filter for the shorterwavelength and highly hazardous ultraviolet radiation (UVR) from the sun,protecting life on Earth from its potentially harmful effects. Ozone absorbs this UVradiation and breaks down to oxygen. Oxygen is different from ozone.

There is an inverse relationship between stratospheric ozone and solar UVRmeasured at the Earth's surface, i.e. the lower the ozone levels, the higher the solarUVR. The formation of ozone holes severely affects ozone's ability to filter UVrays.

Other options can be eliminated as it does not confirm to the definition of a cartel.

Learning: A cartel is a collection of businesses or countries that act together as asingle producer and agree to influence prices for certain goods and services bycontrolling production and marketing. A cartel has less power than a monopoly.This is because cartels do not control the entire market, as monopolists usually do.

OPEC was formed when the international oil market was largely dominated by agroup of multinational companies known as the 'seven sisters'. The formation ofOPEC represented a collective act of sovereignty by oil exporting nations, andmarked a turning point in state control over natural resources.

OPEC's mandate is to "coordinate and unify the petroleum policies" of its membersand to "ensure the stabilization of oil markets in order to secure an efficient,economic and regular supply of petroleum to consumers, a steady income toproducers, and a fair return on capital for those investing in the petroleum industry.

In 2014 OPEC comprised twelve members: Algeria, Angola, Ecuador, Iran, Iraq,Kuwait, Libya, Nigeria, Qatar, Saudi Arabia, the United Arab Emirates, andVenezuela.

pressures of mounting taxes.

Learning:Other reasons were:

The Mughals did not follow any definite law of succession. After the death ofevery emperor, there ensued a bloody war of succession amongst his sons.The successors of Aurangzeb were both weak and incompetent. This reducedthe effectiveness of imperial administration.New powers such as the Sikhs, Jats and Marathas came onto the scene.Gradually they broke off from the Mughal domination and established theirown independent states.Governors (subadars) often controlled the offices of revenue and militaryadministration (diwani and faujdari) as well. This gave them extraordinarypolitical, economic and military powers over vast regions of the MughalEmpire. As the governors consolidated their control over the provinces, theperiodic remission of revenue to the capital declined.The Europeans, especially the British, by way of diwani rights; fortificationetc played an important role in putting an end to the Mughal Empire.The invasions of Nadir Shah and Ahmad Shah Abdali proved fatal for theMughal Empire

Answer Justification :

Explanation: Option (b) is not used in quartz clocks, hence wrong. Option (c) isused in atomic clocks, hence wrong. Option (d) is used in pulsar clocks, hence alsowrong.

Learning : A quartz clock is a clock that uses an electronic oscillator that isregulated by a quartz crystal to keep time. This crystal oscillator creates a signalwith very precise frequency, so that quartz clocks are at least an order of magnitudemore accurate than mechanical clocks.

Chemically, quartz is a compound called silicon dioxide. Many materials can beformed into plates that will resonate. However, quartz is also a piezoelectricmaterial: that is, when a quartz crystal is subject to mechanical stress, such asbending, it accumulates electrical charge across some planes. In a reverse effect, ifcharges are placed across the crystal plane, quartz crystals will bend. Since quartzcan be directly driven (to flex) by an electric signal, no additional speaker ormicrophone is required to use it in a resonator.

The electronic circuit is an oscillator, an amplifier whose output passes through thequartz resonator, and that is how the clock counts time.

Learning:A possible reason for India not signing the Refugee convention may bethat a protection framework will encourage refugee inflow in India putting pressureon resources. South-Asian borders are also very porous and any conflict can result ina mass movement of people.

However, India does protect refugees. The Indian refugee protection framework isbased on executive decisions; judicial pronouncements; and internationalconventions (1984 Convention against torture which prevents forcible repatriation ofrefugees). For e.g. under the RTA, even refugees can claim right to education. Theyare also entitled to public health facilities; justice systems etc.

26 Tibetan antelope or Chiru is endangered becauseTibetan antelope or Chiru is endangered becauseA.of illegal poaching for its fur ShahtooshB.of disruption in its local food chain due to heavy construction andC.anthropgenic activitiesmany Chirus have failed to survive frequent avalanches in the Tibetan regionD.

User Answer : BCorrect Answer : BAnswer Justification :

Explanation & Learning: The exceptionally fine underfur of the Tibetan antelopeor chiru insulates it against the harsh climate of the Tibetan plateau. Unfortunately,this fur, known as shahtoosh, also makes the chiru a target for illegal hunters.

Demand for shahtoosh, which is used to make luxury shawls, has pushed the Tibetanantelope to the brink of extinction. The wool is so fine, the shawls can be pulledthrough a wedding ring.

However, the antelope must be killed for the fur to be collected, and it takes around4 chiru to make a single shawl.

Shahtoosh shawls were traditionally given as wedding gifts in India. Despite strictcontrols on trade of shahtoosh products and CITES listing, there is still demand forthese luxury items. Within India, shawls are worth $1,000-$5,000, internationallythe price can reach as high as $20,000.

User Answer : ACorrect Answer : AAnswer Justification :

Explanation: Burning of Wood is a chemical changes as after burning theproperties and composition of wood change irreversibly. So, statement 1 is correct.

Freezing a mixture is reversible, as well as, its properties does not change. So,statement 2 is incorrect.

The same applies to a blotting paper. By absorbing the ink, its physical properties orcomposition has not changed. So, statement 3 is incorrect.

Learning : Properties such as shape, size, colour and state of a substance are calledits physical properties. A change in which a substance undergoes a change in itsphysical properties is called a physical change. A physical change is generallyreversible. In such a change no new substance is formed.

There will be no unreasonable discrimination for citizens in participation for public2.offices.Same legal provisions apply on all citizens irrespective of their social or political3.stature.Select the correct answer using the codes below.

1 onlyA.2 and 3 onlyB.1 and 2 onlyC.2 onlyD.

User Answer : CCorrect Answer : DAnswer Justification :

Explanation : All citizens are not treated alike by the state. For e.g. disabled andtransgender are provided reservation in public jobs and social security. This is muchgreater than that provided to normal public. There are numerous examples ofpositive discrimination (SCs, STs, women etc). Therefore, statement 1 is incorrect.

The state can discriminate reasonably when it comes to public employment. For e.g.a state government can prescribe domicile requirement for local jobs. But,unreasonable discrimination (e.g. on the basis of religion) is not allowed. So,statement 2 is correct.

Same legal provisions do not apply to all citizens. For e.g. women cannot be calledto police station for inquiry in night; men can be. Punishment for sexual abuse ismore severe for a civil servant than for a normal citizen. Take another example, civilservants cannot be dismissed without giving them a chance to be heard. The same isnot true for all government employees. So, statement 3 is incorrect.

Therefore, Right to equality does not mean complete equality. It simply meansabsence of unreasonable discrimination.

32 In a metropolitan city, who is the authority to usually decide where a public park shouldbe established?

CEO, Zila ParishadA.District CollectorB.Local MLAs CommitteeC.Ward CouncillorsD.

User Answer : DCorrect Answer : DAnswer Justification :

Explanation : CEO, Zila Parishad is usually an IAS officer who is incharge ofexecuting decision taken by the Ward Councillors. He does not take such publicdecisions himself. He can advise the councillors though. So, option (a) is incorrect.

District Collector in a metropolitan area does not enjoy as many powers as he doesin a small town or a village. Municipal Corporation enjoys greater authority inallocating public resources in a metropolitan city. Therefore, option (b) is incorrect.

There is no official local MLAs committee as such. Even if the MLAs were to formsuch committee, they can only recommend establishing a public park. The finaldecision would rst with the Ward Councillors. So, option (c) is also incorrect.

Learning: The city is divided into different wards and ward councillors get elected.The complicated decisions that affect the entire city are taken by groups ofcouncillors who form committees to decide and debate issues. For example, if busstands need to be improved, or a crowded market-place needs to have its garbagecleared more regularly, or there is a drain that cuts through the city that needscleaning etc. It is these committees for water, garbage collection, street lighting etc.that decide on the work to be done.

When the problems are within a ward then the people who live in the ward cancontact their councillors. For example, if there are dangerous electrical wireshanging down then the local Councillor can help them get in touch with theelectricity authority.

While the Councillor's Committees and the councillors decide on issues, theCommissioner and the administrative staff implement these. The Commissioner andthe administrative staff are appointed. Councillors are elected.

33 Tax havens are usually characterized by which of the following?Low or nil taxation for foreigners1.Secrecy regarding wealth and accounts2.Not involved in any Double Taxation Avoidance Agreement (DTAA)3.Select the correct answer using the codes below.

1 and 2 onlyA.2 and 3 onlyB.1 and 3 onlyC.All of the aboveD.

User Answer : CCorrect Answer : AAnswer Justification :

Explanation:Mauritius is considered a tax haven, but it has signed DTAAs withseveral nations. Hence, statement 3 is incorrect.

DTAA aims at avoiding taxing a company doubly by both the host nation and thehome nation. For e.g. Microsoft is a US based company also operating in India. Ifboth countries charge it at the normal corporate tax rates, the company will end uppaying at least 60% of its profits as taxes. To avoid this situation, countries enterinto DTAA and agree for a reasonable mutual division of taxes.

Learning:The term ‘tax haven’ has been widely used since the 1950s. However,there is no precise definition of the term. Mauritius, cayman Islands etc are countedas Tax havens. Some common characteristics are:

typically small countries/ jurisdictions, with low or nil taxation for foreignerswho decide to come and settle thereOffer strong confidentiality or secrecy regarding wealth and accounts,making them very attractive locations for safe keeping of unaccounted wealthoffer a very liberal regulatory environment and allow opaque existence,where an entity can easily be set up without indulging in any meaningfulcommercial activity and yet claim to be a genuine business unit, merely bygetting itself incorporated or registered in that jurisdiction.lack of adequate capital controls

Offshore Financial Centres: Some of the old tax havens have adopted the morebenign designation of ‘offshore financial centre’ (OFC) and tend to describethemselves as financial centres specializing in non-residential financial transactions.

Constructive and destructive interference of the lightA.Diffraction and dispersion of light onlyB.Refraction and reflection of light onlyC.Total internal reflection of light onlyD.

User Answer : CCorrect Answer : AAnswer Justification :

Explanation: Diffraction is the slight bending of light as it passes around the edgeof an object. Dispersion is splitting of light into its 7 colour components. These donot explain the phenomenon of rainbow formation. So, option (b) is wrong.

Refraction, reflection, and total internal reflection of light do take place in theprocess, but they do not explain the entire phenomenon of rainbow phenomenon. So,option (a) is the most appropriate.

User Answer : CCorrect Answer : CAnswer Justification :

Explanation:There is no gravitation anomaly in the core of the earth. Thus, option(a) is incorrect.

Movements of ocean water do not transport continent floors. It is not capable ofdoing so. Thus, option (b) is also wrong.

Periodic expansion and contraction of earth’s crust may happen due to temperaturechanges. But, these are not significant enough to cause large scale movement of

tectonic plates. So, option (d) is also wrong.

Learning:The lithosphere is broken into a number of plates known as theLithospheric plates. These plates move around very slowly – just a few millimetreseach year. This is because of the movement of the molten magma inside the earth.The molten magma inside the earth moves in a circular manner.

51 A meander loop cuts off from the river and forms an ox-bow lake. How is the lakeformed?

Lateral erosion of all banksA.River bed erosionB.Continuous erosion and deposition on the sides of the meanderC.Deposition on all banksD.

User Answer : CCorrect Answer : CAnswer Justification :

Explanation: Not all banks in a river course are eroded. There is deposition onsome banks and erosion on some. So, options (a) and (d) are wrong.

For e.g. when a river rushes into a bend, there is likely to be erosion of one bank,and deposition on the opposite one. This is because velocity of water on the twosides of bank is different. Where velocity is more, erosion takes place, and where itis less deposition takes place.

Option (b) is also wrong, as river bed erosion does not solely lead to the formationof ox-bow lakes. However, it is true that the silt carried by the river is due to thisbed erosion only.

Learning: As the river enters the plain it twists and turns forming large bendsknown as meanders. Due to continuous erosion and deposition along the sides of themeander, the ends of the meander loop come closer and closer. In due course of timethe meander loop cuts off from the river and forms a cut-off lake, also called an ox-bow lake.

Aiding conduction of heat in atmosphereC.Capturing the ultraviolet (UV) portion of lightD.

User Answer : ACorrect Answer : AAnswer Justification :

Explanation: CO2 does not trap direct solar radiation (as explained below). So,option (b) is wrong.

Heat conduction is done by contact of air with surface of earth, not by carbondioxide. So, option (c) is also wrong.

It does not also capture UV rays (that is done by Ozone layer). So, option (d) iswrong.

Learning: Fossil fuels such as gasoline, methane and propane contain mostlycarbon. When these fuels are burned, they react with oxygen and produce carbondioxide.

Most of the light energy from the sun is emitted in wavelengths shorter than 4,000nanometers. The heat energy released from the earth, however, is released inwavelengths longer than 4,000 nanometers. Carbon dioxide doesn't absorb theenergy from the sun, but it does absorb some of the heat energy released from theearth.

When a molecule of carbon dioxide absorbs heat energy, it goes into an excitedunstable state. It can become stable again by releasing the energy it absorbed. Someof the released energy will go back to the earth and some will go out into space.

So in effect, carbon dioxide lets the light energy in, but doesn't let all of the heatenergy out, similar to a greenhouse.

Answer Justification :

Explanation: Earth's hydrological cycle is only partly responsible for the weather.For e.g. rainfall pattern, movements of ocean water etc. So, option (a) is incorrect.

Primordial heat inside the earth manifests itself in form of moving molten magmainside the earth. This however is responsible for tectonic and geo-morphologicalprocesses, not weather phenomenon. So, option (b) is also wrong.

Rotation of earth does cause wind movements; change of day and night; distributionof heat on earth etc. However, it does not explain several other phenomena such asseasons on earth; extreme heat and cold in Poles etc. So, option (c) is also incorrect.

Sun’s energy causes all these, and is ultimately responsible for life and activity onearth, which also subsumes weather phenomena. Hence, option (d) is the answer.

Learning : sun is the primary source of energy that causes changes in the weather.Energy absorbed and reflected by the earth’s surface, oceans and the atmosphereplay important roles in determining the weather at any place.

Heat from Sun causes changes in temperature; pressure; evaporation; biologicalactivity etc. All these in turn determine the weather at a place.

User Answer : ACorrect Answer : BAnswer Justification :

Explanation:Option (a) refers to sedimentary rocks. But, Basalt is an igneous rock.So, option is incorrect.

Option (c) talks about metamorphic rocks, hence incorrect.

Option (d) talks about a combination of both, which is also incorrect.

Learning:Lava is fiery red molten magma coming out from the interior of the earthon its surface. When this molten lava comes on the earth’s surface, it rapidly coolsdown and becomes solid. Rocks formed in such a way on the crust are calledextrusive igneous rocks. They have a very fine grained structure. For example,basalt. The Deccan plateau is made up of basalt rocks.

Sometimes the molten magma cools down deep inside the earth’s crust. Solid rocksso formed are called intrusive igneous rocks. Since they cool down slowly they formlarge grains. Granite is an example of such a rock.

reduced fiscal deficit (subsidies) and domestic prices in India. This reduced inflationto a great extent. So, statement 1 is correct.

Due to competitive global markets, soft global prices led to reduction in Indiandomestic prices. So, statement 2 is also correct.

Tight monetary policy contained the growth of money supply in India, which helpedthe moderation of inflation and inflationary expectations. Thus, statement 3 is alsocorrect.

However, rupee did not appreciate. It only became more stable since the beginningof the year. Therefore, statement 4 is wrong.

Moderation in wagerate growth reduced demand pressures on proteinbaseditems.Base effect also contributed to thedecline in headline inflation.

Learning:Inflation is caused by increases in the supply of money available for usein a nation's economy. It means that too much money is chasing too few goods.

Inflation can also occur when the economy 'overheats' because of excess aggregatedemand (this is called demand-pull inflation). The causes of disinflation are theopposite, either a decrease in the growth rate of the money supply, or a businesscycle contraction (recession).

If the central bank of a country enacts tighter monetary policy, that is to say, thegovernment start selling its securities, this reduces the supply of money in aneconomy. This contraction of the monetary policy is known as quantitativetightening technique.

User Answer :Correct Answer : AAnswer Justification :

Explanation & Learning: BoP is composed of current account as well as capitalaccount. Current account deficit is shown as CAD which comprises of tradesurplus/deficit; invisibles surplus/deficit, remittances outflow/inflow etc.

Capital account consists of external commercial borrowings, loans taken bygovernment, long-term investments abroad, FDI, FII etc.

So, even if CAD is in surplus, it is possible that foreign debt and capital outflows(capital account) are more than CAD. This makes the BoP negative, and there is anet outgo of foreign exchange reserves in this case. So, option (b) is not alwayscorrect.

Same is true for option (c). Even if trade is in surplus, total CAD and BoP may benegative. So, option (c) is also incorrect.

Similarily even if capital account is in surplus, it is possible that CAD is highly indeficit. Thus, there may be a net outgo of foreign exchange. So, option (d) is alsoincorrect.

Learning: The public health service is a chain of health centres and hospitals run bythe government. They are linked together so that they cover both rural and urbanareas and can also provide treatment to all kinds of problems – from commonillnesses to special services.

At the village level there are health centres (sub-centres) where there is usually anurse and a village health worker. They are trained in dealing with commonillnesses and work under the supervision of doctors at the Primary Health Centre(PHC).

Such a centre covers many villages in a rural area. At the district level is the DistrictHospital that also supervises all the health centres.

Therefore the hierarchy of Indian PHS is as follows: Sub-centre<PHC<CHC<Sub-divisional Hospital<District Hospital

User Answer : CCorrect Answer : CAnswer Justification :

Explanation: When all in the same line, high (spring) tides are formed. So, option(a) is wrong.

Options (b) and (c) do not lead to low neap tides. Moreover, it is not possible forearth to be ‘centred’ between Sun and Moon.

Learning: The strong gravitational pullexerted by the sun and the moonon theearth’s surface causes thetides. The water of the earth closerto the moon gets pulledunderthe influence of the moon’sgravitational force and causes hightide.

During the full moon and newmoon days, the sun, the moon andthe earth are in thesame line andthe tides are highest. These tidesare called spring tides. But whenthemoon is in its first and lastquarter, the ocean waters get drawnin diagonally oppositedirections bythe gravitational pull of sun andearth resulting in low tides.

To enable diplomats to carry out their duties without obstruction in the Cold War2.environmentWhich of the above is/are true?

1 onlyA.2 onlyB.Both 1 and 2C.NoneD.

User Answer : DCorrect Answer : BAnswer Justification :

Explanation : Even if both nations are signatory of the Vienna conventions, thehost nation can deny keeping and maintaining of embassy to a foreign nation. Thus,statement 1 is wrong.

Learning: 1961 Vienna conventions and the Convention on Consular Relations,1963 have been ratified by 187 countries, including India. This means, it is a lawunder the Indian legal framework and cannot be violated.

1961 Vienna Conventions says diplomats "shall enjoy immunity from the criminaljurisdiction of the receiving state and also from its civil and administrativejurisdiction.

The Vienna Convention classifies diplomats according to their posting in theembassy, consular or international organisations such as the UN. A nation has onlyone embassy per foreign country, usually in the capital, but may have multipleconsulate offices, generally in locations where many of its citizens live or visit.Diplomats posted in an embassy get immunity, along with his or her familymembers. While diplomats posted in consulates too get immunity, they can beprosecuted in case of serious crimes, that is, when a warrant is issued. Besides, theirfamilies don't share that immunity.

The Convention was meant to enable diplomats to carry out their duties withoutobstruction in the Cold War environment.

User Answer : BCorrect Answer : BAnswer Justification :

Explanation: Land surfaces break cyclone as supply of moisture is cut-off. So,option (a) is wrong.

Absence of clouds reduces the strength of a cyclone. The process of formation ofclouds involves evaporation of water, and then rainfall. As explained below, rainfallwill involve condensation which will enhance the strength of a cyclone. So, option(c) is also wrong.

Lowering temperature of sea water will reduce formation of water vapour andincrease the pressure of the eye of cyclone. This will reduce the strength instead ofincreasing it.

Learning : Before cloud formation, water takes up heat from the atmosphere tochange into vapour. When water vapour changes back to liquid form as raindrops,this heat is released to the atmosphere. The heat released to the atmosphere warmsthe air around. The air tends to rise and causes a drop in pressure. More air rushes tothe centre of the storm. This cycle is repeated. The chain of events ends with theformation of a very low-pressure system with very high-speed winds revolvingaround it.

It is this weather condition that we call a cyclone. Factors like wind speed, winddirection, temperature and humidity contribute to the development of cyclones.

It will lead to greater capital flows in India.A.It may lead to withdrawal of some hot money from India.B.It may destabilize the banking system in India.C.It will bring short-term stability to Indian money markets.D.

User Answer :Correct Answer : BAnswer Justification :

Explanation: Interest rates are the returns that investors enjoy in a particularcountry. If the US hikes interest rates, FIIs will get better returns in US (even thoughinterest rates in India are higher). This is because US is considered a less riskymarket than India. Therefore, this will lead to capital outflow from India. It will bemostly hot money which travels (speculates) around the globe in search of betterreturns.

It will bring short-term instability to Indian money markets.

So, options (a) and (d) will be wrong.

Indian banking system will not be affected by such short-term volatility in money orCapital markets. So, option (c) is also incorrect.

Learning:The Federal Reserve kept rates near zero since 2008 financial crisis in abid to kick-start the US economy. The sustained low interest rate regime led tooutflow of money from US, and inflow of liquidity across the globe.

If the Fed hikes rates, some foreign investors are expected to book profit in theirholdings in Indian shares and bonds; they will likely repatriate funds back to the US,where buying high interest rate bearing bonds will become an attractive bet.

With the decline of the Mughal Empire, many painters moved out to the courts ofthe emerging regional states such as Rajasthan, Deccan and Himachal.

Moreover, Nadir Shah’s invasion and the conquest of Delhi in 1739 resulted in themigration of Mughal artists to the Himalayan foothills to escape the uncertainties ofthe plains.

Therefore, the modern-day state of Himachal Pradesh attracted artisans. By the lateseventeenth century this region had developed a bold and intense style of miniaturepainting called Basohli.

The most popular text to be painted here was Bhanudatta’s Rasamanjari. With thehelp of patrons, Kangra school of painting was found here.
