QUESTION: 1

### With reference to Low Earth Orbits (LEO), consider the following statements: 1. Satellites in LEO suffer high atmospheric drag compared to those in geostationary orbit. 2. Satellites in LEO have high dwell time over a particular area. Q. Which of the statements given above is/are correct?

Solution:

- For the LEO Satellites there is still some atmospheric drag. Even though the amount of atmosphere is far too little to breath, there is enough to place a small amount of drag on the satellite or other object.

- As a result, over time these objects slow down and their orbits slowly decay. Simply put, the satellite or spacecraft slows down and this allows the influence of gravity to pull the object towards the Earth.

- Satellites in this orbit also have a smaller dwell time i.e., the time a satellite sits over one part of globe.

QUESTION: 2

### Human bodies can be scanned with Magnetic Resonance Imaging (MRI) because they contain

Solution:

- When patients slide into an MRI machine, they take with them the billions of atoms that make up the human body.

- For the purposes of an MRI scan, we’re only concerned with the hydrogen atom, which is abundant since the body is mostly made up of water and fat.

- All of the atoms are going in various directions, but when placed in a magnetic field, the atoms line up in the direction of the field.

- These hydrogen atoms have a strong magnetic moment, which means that in a magnetic field, they line up in the direction of the field.

QUESTION: 3

### In a closed system, between the system and environment, there is no exchange of 1. Matter 2. Energy 3. Heat

Solution:

- Closed systems are those in which no matter exchange takes place between the system and the environment.

- In isolated system, neither matter nor energy exchange takes place with the environment.

QUESTION: 4

1. By studying the behaviour of objects around them.
2. Calculating the value of red shift.
3. Detecting the gravitational lens effect.

Select the correct answer using the codes given below.

Solution:

Although we cannot see black holes, we can detect or guess the presence of one by measuring its effects on objects around it. The following effects may be used:

1. Mass estimates from objects orbiting a black hole or spiraling into the core

2. Gravitational lens effects

QUESTION: 6

Refrigerators have become a common household appliance. A refrigeration system

Solution:

- Refrigeration is the process of cooling a space, substance, or system to lower and/or maintain its temperature below the ambient one (while the removed heat is rejected at a higher temperature).

- In other words, refrigeration means artificial (human-made) cooling.

QUESTION: 7

With reference to petrol and diesel engine, consider the following statements:

1. A petrol engine draws a mixture of petrol and air while a diesel engine draws only air during suction.
2. Both petrol and diesel engine uses a carburettor.

Q. Which of the statements given above is/are correct?

Solution:

- Carburetor provides a homogeneous Air-Fuel mixture according to the engine load required or throttle position.

- Combustion occurs in diesel engines when fuel is injected into highly compressed air (high temperature because of compression).

- Combustion occurs in petrol engine when the Air-fuel mixture is ignited with the help of spark plug.

- The reason for different combustion theories for diesel and petrol engines is because of nature (volatility, self-ignition temp etc. )of petrol and diesel .

Hence no presence of homogeneous air-fuel mixture is there in diesel engines so there is no question of carburettor there.

QUESTION: 8

Carbon nanotubes, often called the strongest material have which of the following properties?

1. High electrical and thermal conductivity.
2. Very high tensile strength.

Solution:

- Carbon nanotubes can exhibit remarkable electrical conductivity.

- They also have exceptional tensile strength and thermal conductivity because of their nanostructure and strength of the bonds between carbon atoms.

QUESTION: 9

Which of the following is/are charged particle?

1. Ions
3. Neutrons

Solution:

- Free radicals are not charged. Ions can be positively or negatively charged.

- Neutrons are again chargeless.

- Ions always hold a charge, but free radicals are not charged species even if they have unpaired electrons.

QUESTION: 10

Burning biomass for energy does not release

1. Sulphur
2. Mercury
3. Nitrogen

Solution:

The correct option is A.

Burning either fossil fuels or biomass releases carbon dioxide (CO2), a greenhouse gas. However, the plants that are the source of biomass for energy capture almost the same amount of CO2 through photosynthesis while growing as is released when biomass is burned, which can make biomass a carbon-neutral energy source.

QUESTION: 11

Extra Vehicular Activity (EVA) is related to

Solution:

- Extravehicular activity (EVA) is any activity done by an astronaut or cosmonaut outside a spacecraft beyond the Earth's appreciable atmosphere.

- A SAFER is a safety device worn on tethered U.S. EVAs, since the capability of returning to the spacecraft is essential.

QUESTION: 12

The cell wall is present in

1. Bacteria
2. Blue-green algae
3. Plants

Solution:

- Plants and blue-green algae are well known to possess cell wall.

- Bacteria also have cell walls. Gram-positive bacteria possess a thick cell wall containing many layers of peptidoglycan and teichoic acids.

- In contrast, Gram-negative bacteria have a relatively thin cell wall consisting of a few layers of peptidoglycan surrounded by a second lipid membrane containing lipopolysaccharides and lipoproteins.

QUESTION: 13

Consider a body at temperature of 100 units kept in a room with room temperature 20 units.

Event A : The temperature of the body decreased from 100 to 60.
Event B : The temperature of the body decreased from 60 to 20.

Q. Which of the following is true?

Solution:

The question is based on Newton’s Law of Cooling which states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the ambient temperature (i.e. the temperature of its surroundings). So, A will take less time than B.

QUESTION: 14

Assertion (A) – Most satellite TV antenna in India face south, south east or south-west.
Reason (R) – TV transmission satellite mostly uses a geostationary orbit.

Solution:

- Both A and R are true and R is the correct explanation of A.

- TV transmission satellite is in a geostationary orbit.

- Geostationary orbits can only be accomplished with equatorial orbits, and since India is in the northern hemisphere this means the satellite will always be in south direction.

- Very few communication satellites use polar orbits, or any orbit inclined out of the equatorial plane for that matter, to prevent the need for constant reaming of the receiver dish.

QUESTION: 15

With reference to pesticides and insecticides, consider the following statements:

1. Both pesticides and insecticides kill by poisoning, suffocating or paralyzing.
2. Pesticides are a subgroup of insecticides that are specifically used for killing pests.

Q. Which of the statements given above is/are correct?

Solution:

- The difference between a pesticide and insecticide lies in the different function each performs.

- A pesticide is a chemical substance that is used to kill, control, or repel pests, including mammals, fish, and insects.

- As the name implies, an insecticide affects only insects. This means that an insecticide is a subgroup of pesticides.

- Both pesticides and insecticides kill by poisoning, suffocating, or paralyzing.

QUESTION: 16

With reference to sound waves, consider the following statements:

1. Sound waves can undergo diffraction and this phenomenon is used in auditoriums to provide better hearing experience.
2. It is because of diffraction that sound can be heard around corners even though sound travel in a straight line.

Q. Which of the statements given above is/are correct?

Solution:

- Sound waves can undergo interference and this phenomenon is used in auditoriums to provide better hearing experience.

- It is because of diffraction that sound can be heard around corners even though sound travel in a straight line.

- In auditoriums, destructive interference between sound from the stage and sound reflected from other parts of the hall can create dead spots in which both volume and clarity of sound are poor. Such interference can be reduced by use of sound-absorbing materials on reflecting surfaces.

- On the other hand, interference can improve an auditorium’s acoustical qualities. This is done by arranging the reflecting surfaces in such a way that the level of sound is actually increased in the area in which the audience sits.

- When sound waves pass around an obstacle or through an opening in an obstacle, the edge of the obstacle or the opening acts as a secondary sound source, sending out waves of the same frequency and wavelength (but of lower intensity) as the original source.

- The spreading out of sound waves from the secondary source is called diffraction. Because of this phenomenon, sound can be heard around corners despite the fact that sound waves generally travel in a straight line.

QUESTION: 17

Ammeter and Voltmeter are used to measure current and voltage respectively. Which of the following is true about them?

Solution:

- Ammeter is connected in series because it is a very low resistance (nearly zero) device. If it is connected in parallel, it would draw most of the current and would get damaged.

- Voltmeter is connected in parallel because it is a very high resistance device (nearly infinite), if it is connected in series, it would increase the equivalent resistance of the circuit to nearly infinite and no current would flow through the circuit.

QUESTION: 18

There are four fundamental forces in the universe.

1. Electromagnetic force.
2. Gravitational force.
3. Strong nuclear force.
4. Weak nuclear force.

Q. The correct order of these forces from strongest to weakest is

Solution:

- Gravitational force is the weakest among the fundamental forces.

- There are four fundamental forces (that we know of) in our universe: Strong Nuclear, Electromagnetic, Weak Nuclear and Gravitational.

- The strongest one is the Strong Nuclear force, which is responsible for keeping the nuclei of atoms together.

- About one hundred times weaker than the strong nuclear force is the electromagnetic one. This is the strongest force that we experience in our everyday lives.

- In fact, whenever we touch anything we experience the Electromagnetic force. The electrons in our skin repel electrons in whatever we touch through this force.

- The Weak Nuclear force is the one responsible for most decays of particles and nuclei – which is where radioactivity comes from.

- This force is about 10 billion times weaker than the Electromagnetic force.

- The weakest of all is the Gravitational force. In fact, Gravitational force is 10 thousand billion billion billion billion times weaker than the Electromagnetic force.

QUESTION: 19

A virtual image can be formed by

1. Concave mirror.
2. Concave lens.
3. Convex mirror.
4. Convex lens
5. Plane mirror

Solution:

- A plane mirror forms a virtual image positioned behind the mirror.
- A diverging lens (one that is thicker at the edges than the middle) a convex mirror forms a virtual image. Such an image is reduced in size when compared to the original object.

- A converging lens (one that is thicker in the middle than at the edges) or a concave mirror is also capable of producing a virtual image if the object is within the focal length. Such an image will be magnified.

QUESTION: 20

The term ‘micro-finance’ frequently appears in newspapers. Micro-finance includes

1. Small loans
2. Small deposits
3. Money transfer
4. Payment services

Solution:

- Microfinance refers to a variety of financial services that target low-income clients.

- Since the clients of microfinance institutions (MFIs) have lower incomes and often have limited access to other financial services, microfinance products tend to be for smaller monetary amounts than traditional financial services.

- These services include loans, savings, insurance, and remittances (payments). So, microfinance is not limited to loans and deposits only, it includes other financial services also.

QUESTION: 21

Consider the following statements about International Finance Corporation:

1. It is known as the private arm of the world bank.
2. It lends money to private sector companies of all countries.

Q. Which of the statements given above is/are correct?

Solution:

- The International Finance Corporation (IFC) provides financing of private-enterprise investment in developing countries around the world, through both loans and direct investments.

- IFC lends money to private sector companies of its member countries only and not all countries.

QUESTION: 22

Inclusive growth is an important objective of the development process. In this context, which of the following would amount to inclusive growth?

1. Poverty reduction.
2. Disinvestment.
3. Good governance.
4. Skill building.

Solution:

- Inclusive growth is a concept that advances equitable opportunities for economic participants during economic growth with benefits incurred by every section of society.

- Disinvestment is reducing the government ownership in public sector enterprises. It is not in any way related to inclusive growth. The rest three helps in inclusive growth.

QUESTION: 23

National treatment (NT) is an important policy of WTO. NT means

Solution:

- Statement b and c essentially implies the same thing, though they are differently worded.

National treatment:

1) Treating foreigners and locals equally – Imported and locally-produced goods should be treated equally — at least after the foreign goods have entered the market.

2) The same should apply to foreign and domestic services, and to foreign and local trademarks, copyrights and patents. National treatment only applies once a product, service or item of intellectual property has entered the market. Therefore, charging customs duty on an import is not a violation of national treatment even if locally-produced products are not charged an equivalent tax.

QUESTION: 24

Which of the following is/are a part of the participatory development process?

1. State
2. NGOs
3. Pressure groups
4. Cooperatives

Solution:

- In participatory development (PD), people are willingly involved in a wide range of development activities, as agents and beneficiaries of development.

- Participatory development seeks to engage local populations in development projects.

-It is clear from the definition of PD that NGOs, Pressure Groups, and Cooperatives are involved in it. There might be some confusion over how state is a part of PD.

- It is actually the state activity that can facilitate or hinder PD. If state does not allow NGOs or pressure groups, how can they function?

- On the other hand, states through their policy and support can facilitate PD.

- In last few years, the role of the state in participatory development has changed from the reconstruction and development programme to growth, employment and redistribution.

QUESTION: 25

The Trade facilitation agreement (TFA) of the WTO says that farm subsidies cannot be more than 10 percent of the

Solution:

Value of agricultural production. TFA runs in a clause that says farm subsidies cannot be more than 10 percent of the value of agricultural production.

QUESTION: 26

India maintains buffer stocks of food grains. The buffer stocks helps in

1. providing food security
2. incentivizing farmers
3. stabilizing prices
4. running PDS

Solution:

Incentivizing farmers – This is done by announcing the minimum support prices (MSP) and other schemes like price stabilization fund schemes for plantation crops. The buffer stocks helps in providing food through the PDS, thus ensuring food security. It also acts as a cushion during price rises due to shortfall, thus helping in stabilizing prices.

QUESTION: 27

Consider the following economy traits

1) Prolonged increase in demand
2) Heating up of economy
3) Demand-supply lag

Q. They are the characteristic feature of which phase of business/economy cycle?

Solution:

All these are features of a boom phase of business cycle. During boom phase, the demand goes on increasing and the economy heats up. The supply is limited and hence there develops a demand-supply lag.

QUESTION: 28

Which of the following conditions is/are conducive for the formation of tropical cyclones?

1. Large and continuous supply of warm and moist air.
2. Large value of coriolis force.
3. Inflow of air at upper level of atmosphere.

Solution:

Large and continuous supply of warm and moist air is the most important condition for formation of tropical cyclones. Where the coriolis force is zero (like the equator), tropical cyclones do not develop. An upper level outflow of air (and not inflow) helps in formation of tropical cyclones.

QUESTION: 29

When cold front passes over an area then

1. Temperature decreases.
2. Relative humidity increases.
3. sky becomes clear.

Solution:

Relative humidity (RH) decreases when cold front passes over an area. Cold fronts are associated with clear sky and weather while warm fronts have clouds and rainfall.

QUESTION: 30

The Arabian Sea branch of the monsoon is much more powerful than the Bay of Bengal branch because

Solution:

The Arabian Sea is larger than the Bay of Bengal. The Arabian Sea is approximately 1,491 million square miles, while the Bay of Bengal contains approximately 839,000 square miles. Both are located in Asia and are northern areas of the Indian Ocean.

The entire Arabian Sea current advances towards India, whereas only a part of the Bay of Bengal current enters India, the remainder proceeding to Myanmar, Thailand and Malaysia.

Precipitation associated with a warm front is of long duration. Heavy but short duration precipitation occurs because of cold front.

QUESTION: 34

Which of the following region/s will have most of its rainfall in the months of December-January?

1. areas in the borderlands of the Mediterranean sea.
2. central and southern California coast in USA
3. central Chile

Solution:

All these areas have Mediterranean type climate which is characterized by winter rains. As Chile is in southern hemisphere, it will have summer in the months of December-January and hence will have nil or very low rainfall. The other two areas located in northern hemisphere will have most of their annual rains in the winter months of December-January.

QUESTION: 35

The greatest damage to life and property from a hurricane is due to

Solution:

While both strong winds and torrential rains cause damage, the greatest damage is due to the storm surge. Storm surge is an abnormal rise of water generated by a storm, over and above the predicted astronomical tides.

QUESTION: 36

What are the causes of low pressure in the equatorial region?

1. high temperature
2. air convergence
3. high humidity

Solution:

Due to high temperature, a low pressure belt is created in the equatorial region. This gives rise to air convergence in the area. So, air convergence is the effect of low pressure and not its cause. High humidity has no role to play in generation of low pressure areas.

QUESTION: 37

Which of the following areas is/are best suited for formation of air masses?

1. an extensive area with broadly uniform surface of earth.
2. areas having cyclones.
3. hot deserts in tropical regions.

Select the correct answer using the codes given below.

Solution:

Areas having cyclones have converging air flow and are therefore not suited for formation of air masses. Air masses are formed over an extensive area with broadly uniform surface of earth like hot desert region in tropical areas. Anticyclone over an area also helps in formation of air masses as they have divergent air flow.

QUESTION: 38

The Supreme Court is a court of record. This means

1. its judgements are recorded for perpetual memory.
2. it can punish for contempt of Supreme court.
3. it can punish for contempt of High court.

Solution:

As a Court of Record, the Supreme Court has two powers:

(a) The judgements, proceedings and acts of the Supreme Court are recorded for perpetual memory and testimony. These records are admitted to be of evidentiary value and cannot be questioned when produced before any court. They are recognized as legal precedents and legal references.

(b) It has power to punish for contempt of court, either with simple imprisonment for a term up to six months or with fine up to Rs. 2,000 or with both. In 1991, the Supreme Court has ruled that it has power to punish for contempt not only of itself but also of high courts, subordinate courts and tribunals functioning in the entire country.

QUESTION: 40

In the order of precedence, the speaker has an equal rank to

Solution:

The speaker is given a very high position in the order of precedence. He is placed at seventh rank, along with the Chief Justice of India. This means, he has a higher rank than all cabinet ministers, except the Prime Minister or Deputy Prime Minister.

QUESTION: 41

Consider an ordinary bill that originated in the legislative assembly and is sent to the legislative council. If the council rejects the bill then

Solution:

The legislative assembly passes the bill for the second time. The legislative assembly can override the legislative council by passing the bill for the second time and not vice versa. The mechanism of passing the bill for the second time to resolve a deadlock applies to a bill originating in the legislative assembly only. When a bill, which has originated in the legislative council and sent to the legislative assembly, is rejected by the latter, the bill ends and becomes dead. The Constitution does not provide for the mechanism of joint sitting of two Houses of the state legislature to resolve a deadlock between them over the passage of a bill.

1. public order
2. police
3. land

Solution:

These subjects are within the state list but only Parliament can make laws on them in case of Delhi.

QUESTION: 46

Who among the following takes the oath to ‘uphold the constitution and the laws’?

1. President
2. CAG
3. Supreme court Judge

Solution:

The comptroller and Auditor General is appointed to keep watch on the accounts of the union and the states.
According to-
Section-IV of the Third Schedule of   the Constitution of India prescribes the following form of oath or affirmation to be made by the Judges of the Supreme Court and the Comptroller and Auditor-General of India at the time of assumption of office: —
“I, A.B., having been appointed Chief Justice (or a Judge)  of  the Supreme Court of India (or Comptroller and Auditor-General of India) do swear in the name of God (or solemnly affirm) that I will bear true faith and allegiance to the  Constitution of India as by law established, that I will uphold the sovereignty and integrity of India, that I will duly and faithfully and to the best of my ability, knowledge and judgment perform the duties of my office without fear or favor, affection or ill-will and that I will uphold the Constitution and the laws.”
The oath of president does not includes the phrase ‘to uphold  the constitution and the laws’ rather, according to article 60 of Indian Constitution the oath of the President states ‘will do the best of my ability preserve, protect and defend the Constitution and the law’, which is not asked in the question. Hence the correct answer is the Judges of the Supreme Court and the Comptroller and Auditor-General of India.

QUESTION: 47

Solution:

On the question whether a member is subject to any of the disqualifications under ROPA, 1951, the President’s decision is final. However, he should obtain the opinion of the election commission and act accordingly.

QUESTION: 48

Man causes soil erosion through

1. use of improper ploughing methods.
2. leaving roots of crop in the field after harvest.
3. practicing trash farming.
4. use of heavy machines.

Solution:

Leaving roots of the crop in the field after harvest is a called stubble mulching and it prevents soil erosion. Similarly trash farming means spreading and planting the residue in the field and it prevents soil erosion. Use of heavy machine leads to soil compaction and reduction in infiltration of rainwater. The rainwater then flows heavily as runoff and washes away the soil.

QUESTION: 49

Which of the following evidences support the theory of gradual rise in air temperature and consequent global warming?

1. spreading of tropical diseases towards temperate regions.
2. downward shifting of snow lines of tropical mountains.
3. freezing of permafrost areas.

Solution:

Upward shifting of snow lines of tropical mountains and thawing of permafrost areas indicate global warming. Spreading of tropical diseases towards temperate regions signify that conditions are becoming more tropical due to increase in temperature. It thus also indicate global warming.

QUESTION: 50

Biofuels are fuels extracted from plants and crops and these have various advantages. These include

1. increasing agricultural diversity.
2. reduced use of fertilizers.
3. renewable source of energy.

Solution:

Biofuels may lead to monoculture where farmers will prefer cultivating such crops which can be used in making biofuels. Fertilizers are used in such crops and it will only increase the fertilizer use. Biofuels are renewable sources and this is their advantage compared to non-renewable fossil fuels.

QUESTION: 51

The sources of mercury pollution include

1. coal fired thermal power plants.
2. supersonic jets.
3. automobiles.
4. waste incinerators

Solution:

Supersonic jets release nitrogen oxides and not mercury.

Others are sources of mercury pollution –

Coal-fired power plants- Mercury exists naturally in coal, making coal-fired power plants the largest source of mercury pollution in this country

Trash incinerators Hazardous waste, medical waste, and regular garbage incinerators release 13.1 tons (or about 26,000 pounds) of mercury every year, according to statistics from the EPA. The mercury comes from common household items, such as compact fluorescent light bulbs and thermostats, and from automobile scrap.

Despite common perceptions that mercury is used in thermometers and blood pressure machines, the medical industry has switched to mercury-free versions of those tools, and medical waste now accounts for the smallest percentage of mercury emissions from incinerators.

QUESTION: 56

Nagarjuna’s Shunyavada is expounded in -

Solution:

Madhyamika, “school of the Middle Way,” that began about the 2nd century. Madhyamika profoundly influenced the development of Mahayana, especially in China and Tibet and, eventually, Japan.
Nagarjuna was a patriarch of Mahayana and the founder of Madhyamika.
The Wisdom Sutras focus on sunyata, “emptiness.” Nagarjuna’s principle contribution to Buddhism was his systematization of the sutras’ teachings which is found in Madhyamika.

QUESTION: 57

The High Courts at Calcutta, Bombay and Madras to replace the Sadar Courts of Diwani and Nizamat were established in the year—

Solution:

By Indian High Courts Act 1861, the Supreme & Sadar Courts were amalgamated.
