Q.1 Consider the following statements:1. Sun is the only source of energy for all ecosystems on Earth2. Of the incident solar radiation more than 50 per cent of it is PhotosyntheticallyActive Radiation (PAR)Select the correct codeA. Only 1B. Only 2C. BothD. None
Answer : D,
Solution :
Except for the deep sea hydro-thermal ecosystem, sun is the only source of
energy for all ecosystems on Earth. Of the incident solar radiation less than 50 per cent of it
is photosynthetically active radiation (PAR).
Q.2 Arrange the following in increasing order of ‘Productivity in Ecosystem’ (metric tonneper year)A. Woodland and shrubland< tropical rain forest < Continental shelf < Open seaB. Continental shelf < Woodland and shrubland< Tropical rain forest < Open oceanC. Tropical rain forest< Continental shelf< Woodland and shrubland< Open oceanD. Woodland and shrubland< Continental shelf < Tropical rain forest < Open oceanWhich of
the following is correct?
Answer : D,
Solution :
In ecology, productivity or production refers to the rate of generation of biomass in
an ecosystem. It is usually expressed in units of mass per unit surface (or volume) per unit
time, for instance grams per square metre per day (g m−2 d−1). The mass unit may relate
to dry matter or to the mass of carbon generated. Productivity of autotrophs such as
plants is called primary productivity, while that of heterotrophs such as animals is
called secondary productivity.

Q.3 Consider the following statements about ecological pyramids1. Grassland and forest ecosystem have similar Pyramid of Numbers.2. Pyramid of Biomass is the most accurate among three ecological pyramids-Number,Biomass and Energy.3. Pyramid of Energy is always upright in nature irrespective of type of ecosystem.Select the correct codeA. 1 and 2B. 1, 2 and 3C. Only 2D. Only 3
Answer : D,
Solution :
There are three ways an ecological pyramid can be represented. A Pyramid of Numbers can
be generated by counting all the organisms at the different feeding levels. As you might
guess, this can be a very difficult task since we are not just identifying each species in the
ecosystem. We are also counting how many of each species is present. On occasion, this
approach will not work. For example, one tree (a producer) can represent an ecosystem
and harbor numerous populations of herbivores and carnivores. Thus, the bottom of the
pyramid would be very small and not flared out.
A second type of pyramid is called a Pyramid of Biomass where organisms are collected
from each feeding level, dried and then weighed. This dry weight (biomass) represents the
amount of organic matter (available energy) of the organisms. [Note that there are
alternate, nonlethal ways to determine biomass.] While this approach will generally create a
pyramid that illustrates energy flow, its use can also produce an inverted pyramid. For
example, in aquatic ecosystems, phytoplankton could reproduce and then be eaten rapidly
Study IQwww.studyiq.com, [email protected]
Page - 4/58
by zooplankton. Therefore, it would be possible to have few herbivores and a lot of
carnivores when a collection is taken
A third type of pyramid called a Pyramid of Energy Flow tends to resolve these problems.
This approach necessitates measuring the caloric value of the different organisms that make
up the community. It nicely shows how energy is continually decreasing along the food
chain from producers to top level carnivores.
The pyramids of numbers and biomass may be upright or inverted depending upon the
nature of the food chain in the particular ecosystem, whereas pyramids of energy are
always upright.
In a forest ecosystem, however, the pyramid of numbers is somewhat different in shape.
The producers, which are mainly large-sized trees, are lesser in number, and form the base
of the pyramid. The herbivores, which are the fruit-eating birds, elephants, deer’s etc. are
more in number than the producers.
Q.4 Which among the following can effectively be examples of ‘Secondary Succession’?1. Formation of a new Island after volcanic eruption2. The renewal of a forest after a fire3. A flooded land4. The renewal of a crop after harvestingSelect the correct optionA. 1, 2 and 3B. 2, 3 and 4C. 1, 3 and 4D. All
Answer : B,
Solution :
Examples of secondary succession include:
§ The renewal of a forest after a fire: The fire itself destroys a majority of different
types of trees and plant life. Because seeds and roots and other plant and tree parts
Study IQwww.studyiq.com, [email protected]
Page - 5/58
remain in and on the soil, gradually the plants and trees begin to grow again and
eventually return to the state of the original ecosystem.
§ The renewal of a crop after harvesting: A crop is completed harvested when it
becomes ripe. Without new seeds being planted, the crop can regenerate the
following year due to the plants and seeds that remained after harvesting.
§ A forest renews after logging: A large amount of trees were chopped down by
loggers in order to create building materials. Over time, trees grow in and the area
returns to its previous state.
§ Renewal after disease: A plant population can be very negatively affected by a
variety of infectious plant diseases. If the entire population dies, but the soil and
roots remain, it is possible for secondary succession to occur and for the population
of those plants to to return.
§ A flood can ruin farmlands. However, because the soil remains after the waters
recede, over the course of many years a natural secondary succession can occur and
the vegetation that had previously grown there can grow again.
§ Plants can be very susceptible to attack from pests, particularly if there is an
overpopulation of those pests. When this occurs, the plant population in one area
can be completely destroyed. However, when the pest overpopulation is resolved,
the plants are able to live again and thrive in the soil in which they previously had
lived.
Q.5 If the concentration of oxygen gets doubled in the atmosphere, what can be thepossible effects of the same?1. We will die young2. Most insects will grow bigger in size3. We will be less prone to sickness4. Our Vehicle will give better mileage
Study IQwww.studyiq.com, [email protected]
Page - 6/58
Select the correct optionA. 1, 2 and 3B. 1, 3 and 4C. 1, 2, 3 and 4D. 2, 3 and 4
Answer : C,
Solution :
§More oxygen will generate more free radical that will exacerbate the aging process
through Oxidative Stress. Oxidative Stress will interfere in numerous cellular
processes like protein production, DNA replication etc. Hence age will get reduced.
§ Immune system will get a boost as a result of oxidation and hence will help in
fighting diseases (Less sickness)
§ Many insects rely on gaseous diffusion for respiration therefore the maximum body
size depends on the proportion of oxygen gas in the atmosphere. Hence size of
insects will increase.
§ Oxygen-enriched air improves engine performance by producing hotter reactions
and reducing the proportion of nitrogen, which reduces heat transfer and hence will
give better mileage.
Q.6 The ecological footprint is a measure of human demand on the Earth's ecosystems. Itmeasures-1. How much of the biological capacity of the planet is demanded by a given humanactivity or population2. Ecological Footprints is calculated for overall activity of a nation or population andactivities such as industrialization etc.3. The disadvantage of Ecological Footprint is that it cannot be calculated for individualpeople or area.Select the wrong statement/sA. 1 and 2B. Only 2C. 1 and 3
Study IQwww.studyiq.com, [email protected]
Page - 7/58
D. Only 3
Answer : D,
Solution :
The Ecological Footprint is a resource accounting tool that measures how much biologically
productive land and sea is used by a given population or activity, and compares this to how
much land and sea is available. Productive land and sea areas support human demands for
food, fibre, timber, energy, and space for infrastructure. These areas also absorb the waste
products from the human economy. The Ecological Footprint measures the sum of these
areas, wherever they physically occur on the planet. The Ecological Footprint is used widely
as a management and communication tool by governments, businesses, educational
institutions, and non-governmental organizations.
Ecological Footprint accounts answer a specific research question: how much of the
biological capacity of the planet is demanded by a given human activity or population? To
answer this question, the Ecological Footprint measures the amount of biologically
productive land and water area an individual, a city, a country, a region, or all of humanity
uses to produce the resources it consumes and to absorb the waste it generates with
today’s technology and resource management practices. This demand on the biosphere can
be compared to biocapacity, a measure of the amount of biologically productive land and
water available for human use. Biologically productive land includes areas such as cropland,
forest, and fishing grounds, and excludes deserts, glaciers, and the open ocean
Ecological Footprints can be calculated for individual people, groups of people (such as a
nation), and activities (such as manufacturing a product).
The Ecological Footprint of a person is calculated by considering all of the biological
materials consumed, and all of the biological wastes generated, by that person in a given
Study IQwww.studyiq.com, [email protected]
Page - 8/58
year. These materials and wastes each demand ecologically productive areas, such as
cropland to grow potatoes, or forest to sequester fossil carbon dioxide emissions. All of
these materials and wastes are then individually translated into an equivalent number of
global hectares.
Q.7 Which of the following describes the relationship of Mutualism?1. Pollination2. Rhizobium3. Human and Bacteria4. ZoochorySelect the correct code-A. 1, 2 and 3B. 2. 3 and 4C. 2 and 4D. All
Answer : D,
Solution :
A mutualistic relationship is when two organisms of different species "work together," each
benefiting from the relationship. In mycorrhizal associations between plant roots and fungi
with the plant providing carbohydrates to the fungus in return for primarily phosphate but
also nitrogenous compounds.
Other examples include rhizobia bacteria that fix nitrogen for leguminous plants in return
for energy-containing carbohydrates
Pollination in which nectar or pollen (food resources) are traded for pollen dispersal (a
service) or ant protection of aphids, where the aphids trade sugar-rich honeydew (a byproduct
of their mode of feeding on plant sap) in return for defense against predators such
as ladybugs.
Zoochory is an example where animals disperse the seeds of plants. This is similar to
pollination in that the plant produces food resources (for example, fleshy fruit,
Study IQwww.studyiq.com, [email protected]
Page - 9/58
overabundance of seeds) for animals that disperse the seeds (service).
The bacteria and the human. A certain kind of bacteria lives in the intestines of humans and
many other animals. The human cannot digest all of the food that it eats. The bacteria eat
the food that the human cannot digest and partially digest it, allowing the human to finish
the job. The bacteria benefit by getting food, and the human benefits by being able to digest
the food it eats.
Q.8 Bioluminescence is the production and emission of light by a living organism. Which of
the following exhibit the phenomenon of Bioluminescence?1. Krill2. Fungi3. Bacteria4. Winged beetles5. OctopusSelect the correct code/sA. 1, 2, 4 and 5B. 1, 3, 4 and 5C. 2, 3, 4 and 4D. All
Answer : D,
Solution :
All are bioluminescent species. Winged Beetles are also called Fireflies. Specific types of
bacteria and fungi show this property. The Bioluminescent Octopus, scientifically known
as: Stauroteuthissyrtensis, is a deep sea species that has been relatively little studied. Krill
are bioluminescent animals having organs called photophores that can emit light.

Q.11 Tropical cyclones occur in –A. tropics onlyB. tropics and sub tropics onlyC. subtropics onlyD. tropic, subtropics and extra-tropics
Answer : D,
Solution :
In addition to tropical cyclones, there are two other classes of cyclones within the spectrum
of cyclone types. These kinds of cyclones, known as extratropical cyclones and subtropical
Study IQwww.studyiq.com, [email protected]
Page - 11/58
cyclones, can be stages a tropical cyclone passes through during its formation or
dissipation. An extratropical cyclone is a storm that derives energy from horizontal
temperature differences, which are typical in higher latitudes. A tropical cyclone can
become extratropical as it moves toward higher latitudes if its energy source changes from
heat released by condensation to differences in temperature between air masses; although
not as frequently, an extratropical cyclone can transform into a subtropical storm, and from
there into a tropical cyclone. From space, extratropical storms have a characteristic
"comma-shaped" cloud pattern. Extratropical cyclones can also be dangerous when their
low-pressure centres cause powerful winds and high seas.

Many of the world's largest lakes are located in rift valleys. Lake Baikal in Siberia, a World
Heritage Site, lies in an active rift valley. Baikal is both the deepest lake in the world and,
with 20% of all of the liquid freshwater on earth, has the greatest volume. Lake Tanganyika,
second by both measures, is in the Albertine Rift, the westernmost arm of the active East
African Rift. Lake Superior in North America, the largest freshwater lake by area, lies in the
ancient and dormant Midcontinent Rift. The largest subglacial lake, Lake Vostok, may also lie
in an ancient rift valley.

Q.18 18) “Cornwallis Code was a body of legislation enacted in 1793 by the East India Companyto improve the governance”. Consider the following statements wrt Cornwallis Code-1. To give impetus to Permanent Settlement, Zamindars were given the role of LocalAdministration.2. The Policing and Judicial powers of Zamindar were further enhanced to strengthenthe Permanent Settlement System.Select the correct codeA. Only 1
B. Only 2
C. Both
D. None
Answer : D,
Solution :
Cornwallis Code:
The code contained significant provisions-Governing, Policing and judicial and civil
administration. Its best known provision was the Permanent Settlement (or the zamindari
system enacted in 1793), which established a revenue collection scheme which lasted into
the 20th century.
The system, as codified in these regulations, provided that the East India Company’s service
personnel be divided into three branches: revenue, judicial, and commercial. Private trade
was forbidden to the members of the first two branches, and they were instead
compensated by a new and generous scale of pay. The land revenue assessment (the major
source of revenue) was fixed permanently with zamindars, or hereditary revenue collectors.
These native Indians, provided they paid their land taxes punctually, were treated as
landowners, but they were deprived of magisterial and police functions, which were
discharged by a newly organized government police. This “permanent settlement” provided
the British with an Indian landed class interested in supporting British authority. The local
administration was placed in the hands of the revenue collectors of districts. The judiciary
was reorganized; there were district judges with magisterial powers responsible to
Study IQwww.studyiq.com, [email protected]
Page - 15/58
provincial courts in civil cases and to courts of circuit in criminal cases. The law administered
was Hindu and Muslim personal law and a modified Muslim criminal code. The higher ranks
of the services were restricted to Europeans, thus depriving Indians of any responsible
office.
Q.19 19)The translation of ‘Gentoo Code’ was funded and encouraged by Warren Hastings as amethod of increasing colonial hold over the Indies. Consider the statements regarding theGentoo Code-1. It is also known as Ordinations of the Pundits.2. It was first translated from Persian to English and then from Persian to SanskritSelect the correct optionA. Only 1
B. Only 2
C. Both
D. None
Answer : A,
Solution :
The Gentoo Code is a legal code translated from Sanskrit (in which it was
known as vivādārṇavasetu) into Persian by Brahmin scholars; and then from Persian into
English by Nathaniel BrasseyHalhed, a British grammarian working for the East India
Company. The translation was funded and encouraged by Warren Hastings as a method of
increasing colonial hold over the Indies. It was printed privately by the East India Company
in London in 1776 under the title A Code of Gentoo Laws, or, Ordinations of the Pundits.
Copies were not put on sale, but the Company did distribute them. In 1777 a pirate (and less
luxurious edition) was printed; and in 1781 a second edition appeared. Translations into
French and German were published in 1778.
Q.20 20) Consider the following statements regarding the teachings of BrahmoSamaj1.

B. 1, 2 and 3
C. 1 and 3
D. Only 3
Answer : C,
Solution :
Statements 1 and 3 were the teachings of BrahmoSamaj. The long term
agenda of BrahmoSamaj was to purify Hinduism and to preach monotheism which was
based on twin pillars of reason and the Vedas and Upanishads. So statement 2 is wrong.
Q.21 21)Consider the following statements w.r.t the teachings of Ramakrishna Mission and AryaSamaj-1. Both opposed Image Worship2. Both believed in Oneness of GOD3. They supported proselytization as evident from Shuddhi Movement to reconvert tothe Hindu FoldSelect the correct codeA. 1 and 3
B. Only 2
C. Only 1
D. 1, 2 and 3
Answer : B,
Solution :
Ramakrishna Mission founded by Vivekanada was deeply a religious body, but it was not a
proselytizing body. Unlike Arya Samaj, the Mission recognises the utility and value of image
worship in developing spiritual fervor and worship of the eternal omnipotent God, although
it emphasises the essential spirit and not the symbols or rituals.
Both believed in Oneness of GOD. Shuddhi movement was started by Arya Samaj
Q.22 22)Consider the following statements w.r.t the famous Indigo Revolt that took place inBengal-1.

B. Only 2
C. Both
D. None
Answer : A,
Solution :
The Bengali middle class supported the peasants whole-heartedly. Harish Chandra
Mukhopadhyay thoroughly described the plight of the poor peasants in his newspaper The
Hindu Patriot.
The ryots received moral support from the Indian press in Calcutta as well as the aid of
some Calcutta-trained lawyers. The indigo rebellion has been portrayed in drama, poetry
and popular history in Bengal, thereby drawing the attention of the intelligentsia. Thus it
entered the political awareness and had a far reaching consequence in the later movements
of Bengal.
Q.23 23)The famous revolt of 1857 brought various changes in British Administration of Indiaand the immediate change was the enactment of ‘Act of Parliament 1858’. Consider thefollowing statements w.r.t ‘Act of Parliament 1858’-1. The Secretary of State for India was given the powers that were previously wieldedby the directors of Company and Board of Directors.2. Thus the ultimate power over Indian Administration remained with Secretary ofState.Select the correct statement/sA. Only 1
B. Only 2
C. Both
D. None
Answer : A,
Solution :
First statement is correct. The secretary of State was a member of the British Cabinet and as
such was responsible to Parliament. Thus the ultimate power over India remained with
British Parliament not Secretary of State.

B. 2, 3 and 4
C. 2 and 4
D. All
Answer : C,
Solution :
"No taxation without representation" is a slogan originating during the 1750s and 1760s
that summarized a primary grievance of the American colonists in the Thirteen Colonies,
which was one of the major causes of the American Revolution.
Believing that India should eventually move towards democratic self-government, the Early
Nationalists wanted a larger share in the governing of India.
Early Nationalists demanded the expansion and reform of the Legislative Councils and
British Government was forced by their agitation to pass Indian Councils Act-1892 where the
numbers of the Imperial Legislative Councils as well as the provincial councils was increased.
But the nationalists were totally dissatisfied with the Act and declared it to be a hoax. In
particular, they demanded Indian control over the public purse and raised the slogan that
had earlier become the national cry of the American people during their War of
Independence: ‘No taxation without representation’.

Q.27 27)Consider the following statements with respect to Solar Wind and Earth Wind-1. The solar wind is very strong compared to the wind on Earth2. The solar wind is very weak compared to the wind on Earth, though it is much, muchfaster than Earth wind.Select the correct code-A. Only 1
B. Only 2
C. Both
D. None
Answer : B,
Solution :
The solar wind is very weak compared to the wind on Earth, though it is much,
much faster. When we measure solar wind speeds, we typically get speeds of 1-2 million
miles per hour. They end up being weaker because there is very little of it. Solar wind
density is usually about 100 particles per cubic inch. Thus, a typical pressure from the solar
wind is measure in nanopascals whereas at the Earth’s surface, the atmospheric pressure is
Study IQwww.studyiq.com, [email protected]

100 kilopascals, and surface winds are about 100 pascals. Since solar wind is measured in
nanopascals it is approximately 1000 million times weaker than winds here on Earth.
Q.28 28)Recently Solar Storms were in news. Consider the statements with respect to SolarStorms-1. They are very harmful for Humans and other living organisms on Earth.2. They can affect communication technologies like GPS and radio communications.3. They can also affect Power Grids and Electrical units.Select the wrong statement/sA. 1 and 2
B. Only 1
C. Only 2
D. Only 3
Answer : A,
Solution :
Solar storms are not dangerous to humans on Earth’s surface. These storms
are awesome to contemplate, but they cannot harm our human bodies as long as we remain
on the surface of Earth, where we’re protected by Earth’s blanket of atmosphere.
Remember, there’s every reason to believe that storms on the sun have been happening for
billions of years, since the sun and Earth came to be. If that’s so, then all life on Earth
evolved under their influence.
What is the danger of a solar storm in space? Very high-energy particles, such as those
carried by CMEs, can cause radiation poisoning to humans and other mammals. They would
be dangerous to unshielded astronauts, say, astronauts travelling to the moon. Large doses
could be fatal.
Still, solar storms – and their effects – are no problem for us on Earth’s surface. Earth’s
atmosphere and magnetosphere protect our human bodies from the effects of solar flares.
On the other hand solar storms can be dangerous to our technologies. When a coronal mass
ejection, or CME, strikes Earth’s atmosphere, it causes a temporary disturbance of the
Earth’s magnetic field. The storm on the sun causes a type of storm on the Earth, known as
a geomagnetic storm. They have the potential to affect power grids, and have been known

First statement is wrong. Although Tornados are more frequent than
Hurricanes but cause less damage as compared to Hurricane. The simple reason is the long
lasting nature of Hurricane- few days to weeks. While Tornados lasts for minutes to hours.
Rest statements are true.

Q.31 31) Which of the following can be the easiest way to predict the upcoming Earthquake?A. Huge release of Methane gas
B. Release of Radon gas
C. Release of carbon dioxide
D. None
Answer : B,
Solution :
Uranium is found in low-levels in all rocks and soil. Radon is a gaseous
radioactive decay product of uranium. As the uranium undergoes radioactive decay,
radioactive radon is generated andtrapped in the rocks that contain the uranium.
The earthquake theory involving radon suggests that prior to the actual quake, there is
some subterranean movement where rocks are crushed, soil is un-compacted and the
trapped radon is released producing a pre-quake spike in radon concentration.
So radon presents the following attributes:
§ it is present in all rocks and soil
§ if a rock is broken or if soil is disturbed, radon will be released
§ it is gaseous and air currents / thermal gradients will carry it up to the earth's surface
producing a detectable plume
§ it is radioactive, this makes detecting small amounts or small changes in radon
concentration relatively routine due to well-developed and very sensitive methods
for detecting and accurately measuring radioactivity.
§ Radon has a very short radioactive half-life, a bit under 4 days. Being a gas and
having a short half-life is very useful in terms of measuring radon emissions. If a
radon emission spike occurs, the gas will dissipate quickly and after about 10 halflives
(40 days) normal background levels of radioactivity will return.

Q.32 32)In British India, what is ‘Dastak’ known for?A. A permit exempting European traders, mostly of the British East India Company, from paying customs or
transit duties on their private trade.B. A permit regulating internal trade, mostly for Indian traders.
C. Fee charged by Indian rulers from European Traders when they trade into theirterritory
D. Fee charged by British government for the regulation of domestic trade.
Answer : A,
Solution :
Dastak, in 18th-century Bengal, a permit exempting European traders, mostly
of the British East India Company, from paying customs or transit duties on their private
trade. The name came from the Persian word for “pass.” The practice was introduced
by Robert Clive, one of the creators of British power in India, when he had Mir
Jaʿfar installed as nawab of Bengal in 1757. The attempt of Mir Jaʿfar’s successor, Mir Qāsim,
to annul the use of dastaks led to his overthrow in 1763–64 and the exercise of overt
control of Bengal by the British.
Free dastaks for private trade were finally abolished by Warren Hastings, governor of Bengal
(1775). The system put the Indian trader at a grave disadvantage in competing with the
European and was an important factor in the impoverishment of Bengal under early British
rule.

Maratha Empire represented the same decadent social order as the Mughal Empire did and
suffered from the same underlying weaknesses. They were less disciplined than the Mughal
nobles. Their revenue system was similar to that of the Mughals as also was their
administration. Like the Mughals, the Maratha rulers were also mainly interested in raising
revenue from the helpless peasantry.
For example, they too collected half of the agricultural produce as tax. Unlike Mughals, they
failed even to give sound administration to the people outside Maharashtra. They could not
inspire the Indian people with any higher degree of loyalty than the Mughal succeeded in
doing.

B. Only 2
C. Both
D. None
Study IQwww.studyiq.com, [email protected]
Page - 25/58
Answer : C,
Solution :
Constant warfare and disruption of law and order in many areas during 18th century harmed
the country’s internal trade. Many trading centres were looted by the contestants for power
and by foreign invaders like Nadir Shah. Many of the trade routes were infested with
organized bands of robbers, and traders and their caravans were regularly looted.
Since India was on the whole self-sufficient in handicrafts and agricultural products, it did
not import foreign goods on large scale. On the other hand, its industrial and agricultural
goods had a steady market abroad. Even India remained a land of extensive manufactures.
Indian artisans enjoyed fame all the world over for their skill. India was still a large scale
exporter of cotton and silk fabrics. It is said by Peter the Great of Russia- “ the commerce of
India is the commerce of the world and he, who can exclusively command it is the dictator
of Europe”

D. None
Answer : D,
Solution :
As a result of Subsidiary Alliance, the ally had to agree on the following regulations
· Accept a permanent stationing of British force within his territory and to pay a
subsidy for its maintenance. All this was done allegedly for his protection but was, in
fact, a form through which the Indian ruler paid tribute to the Company. Sometimes
the ruler ceded part of his territory instead of paying annual subsidy.
· It also provided that the Indian ruler would agree to the posting at his court of a
British Resident, that he would not employ any European in his service without the
approval of the British, and that he would not negotiate with any other Indian ruler
without the consent of Governor-General.
· In reality, they lost the right of self-defence, of maintaining diplomatic ties, of
employing foreign experts and of settling disputes with its neighbours.
· It also lost control over the defence and foreign relations. Since statement 2 is
wrong, the correct option to select would be (d) i.e None

Q.48 48)The difference between the market prices and factor cost is equal toA. Indirect taxes paid
B. Subsidies received
C. Capital consumption
D. Indirect tax paid minus subsidies received
Answer : D,
Solution :
Basically, ‘factor cost’ is the ‘input cost’ the producer has to incur in the process of producing
something (such as cost of capital i.e. interest on loans, raw materials, labour, rent, power,
etc.). This is also termed as ‘factory price’ or ‘production cost/price’. This is nothing but ‘price’
of the commodity from the producer’s side. While the ‘market prices’ is derived after adding
the indirect taxes to the factor cost of the product, it means the cost at which the goods reach
the market i.e. showrooms (these are the Cenvat/central excise and the CST which are paid by
the producers to the Central government in India).

Q.50 50)Which one of the following statement is true?A. GDP is always greater then GNP
B. GDP is always lower than GNP
C. GDP is equal to GNP when “income from Abroad” is zero
D. GDP is equal to GNP when “depreciation” is zero
Answer : C,
Solution :
Gross National Product (GNP) is the GDP of a country added with its ‘income from abroad’. The
items which are counted in the segment ‘Income from Abroad’ are:
1. Trade Balance: the net outcome at the year end of the total exports and imports of a
country may be positive or negative accordingly added with the GDP.
2. Interest of External Loans: the net outcome on the front of the interest payments i.e.
balance of the inflow (on the money lend out by the economy) and the outflow (on the
money borrowed by the economy) of the external interests.
3. Private Remittances: the net outcome of the money which inflows and outflows on
account of the ‘private transfers’.
The balance of all the three components of the ‘Income from Abroad’ segment may turn out to
be positive or negative. Thus relationship between GDP and GNP depends on the net value of
income from abroad. When the income from abroad is zero GDP is equal to GNP.

Q.76 Consider the following regarding BRAHMOS Missile jointly developed by India andRussia1. Its range of 290km is governed by Missile technology Control Regime (MTCR) of whichRussia is a member.2. Its only disadvantage is its surface to surface variant.3. It works on the principle of ‘Fire and Forget’.Select the correct codeA. 1 and 2
B. 2 and 3
C. 1 and 3
D. All
Answer : C,
Solution :
Brahmos is a supersonic cruise missile.
MTCR controls the proliferation of missile and unmanned aerial vehicle technology capable
of carrying a 500 kg payload for at least 300 km. Since India is not a member of MTCR and
Russia is, therefore the joint development could not cross the limit of 300 Km and hence the
missile’s range is 290 km
Brahmos can be launched from Submarines, Ships, Land and Air. So, it can be surface to
surface, Submarine to Air and under development Air to Air. Hence second statement is
wrong.

D. None
Answer : C,
Solution :
Lead is a major constituent of the lead-acid battery used extensively in car batteries. It is
Study IQwww.studyiq.com, [email protected]
Page - 47/58
used as a coloring element in ceramic glazes, as projectiles, in some candles to threat the
wick. It is the traditional base metal for organ pipes, and it is used as electrodes in the
process of electrolysis. One if its major uses is in the glass of computer and television
screens, where it shields the viewer from radiation. Other uses are in sheeting, cables,
solders, lead crystal glassware, ammunitions, bearings and as weight in sport equipment.
Once taken into the body, lead distributes throughout the body in the blood and is
accumulated in the bones. Depending on the level of exposure, lead can adversely affect
the nervous system, kidney function, immune system, reproductive and developmental
systems and the cardiovascular system. Lead exposure also affects the oxygen carrying
capacity of the blood. The lead effects most commonly encountered in current populations
are neurological effects in children and cardiovascular effects (e.g., high blood pressure and
heart disease) in adults. Infants and young children are especially sensitive to even low
levels of lead, which may contribute to behavioural problems, learning deficits and lowered

Study IQwww.studyiq.com, [email protected]
Page - 58/58
Answer : D,
Solution :
Coliforms are bacteria that are always present in the digestive tracts of animals, includinghumans, and are found in their wastes. They are also found in plant and soil material.Mostcoliform bacteria do not cause disease. However, some rare strains of E. coli, particularly thestrain 0157:H7, can cause serious illness.
Coliforms are relatively easy to identify, are usually present in larger numbers than moredangerous pathogens, and respond to the environment, wastewater treatment, and watertreatment similarly to many pathogens. As a result, testing for coliform bacteria can be areasonable indication of whether other pathogenic bacteria are present.
