UPSC Paper 1 Mock Test - 13 - Question 1

Advance Pricing Agreements (APAs) are related to

Detailed Solution for UPSC Paper 1 Mock Test - 13 - Question 1

Justification: The APA Scheme was introduced in the Income-tax Act
in 2012 and the “Rollback” provisions were introduced in 2014.
• The scheme endeavours to provide certainty to taxpayers in the
domain of transfer pricing by specifying the methods of pricing
and setting the prices of international transactions in advance.
Learning: Transfer pricing happens when two companies that are part
of the same multinational group trade with each other. For example, if a
subsidiary company sells goods to a parent company, the cost of those
goods paid by the parent to the subsidiary is the transfer price.
• Transfer pricing often complicates tax matters as different entities
of the same company may be taxed at different rates (e.g. service
tax or cess may be different for tobacco or hotels, both in the
domain of ITC).
• Companies often try to evade taxes by showing lower profits in the
high taxation sector, to reduce tax burden.
• APAs avoid this by signing advance agreements regarding the
same.

UPSC Paper 1 Mock Test - 13 - Question 2

You are an intelligence officer and have been taken to an unknown location in Australia. The intelligence team back in India knows your longitude due to the time zone in which you have been captivated. You need to communicate only your latitude to the officers in India to help them evacuate you. You can know the latitude of your place by

Detailed Solution for UPSC Paper 1 Mock Test - 13 - Question 2

Justification: Options B and C will remain constant irrespective of the
position from where you measure these values. So, you cannot determine
your latitude by these values.
Option A would have been helpful if you had been captivated in the
Northern hemisphere. Pole star is not visible from Southern hemisphere
(Australia), hence it is of no use to you.
None of the given options A, B or C is correct.
Learning: In ancient times, people used to determine directions during
the night with the help of stars.
The North star (Pole star) indicates the north direction. It always
remains in the same position in the sky.
Latitude is basically the angle of your place from the centre of the Earth
(equatorial position).

You can either find out this angle OR find out the angle of your place
with respect to the North Pole. Finding the latter is easier as Pole Star is
always found vertically above the North Pole.
If you can find your place’s angle from the Pole star (North Pole), just
subtract it from 90 degrees to arrive at your place’s latitude.

good market for consumption of those goods.
So, clearly statement 1 is wrong.
Statement 4: The Wood’s Despatch recommended the sanction of a
grant-in-aid system in the Indian educational system and argued that
schools must charge fees from their students. So, 4 is also incorrect.
Learning: Outlining the educational policy that was to be followed in
India, it emphasised once again the practical benefits of a system of
European learning, as opposed to Oriental One of the practical uses the
Despatch pointed to was economic.
• European learning, it said, would enable Indians to recognise the
advantages that flow from the expansion of trade and commerce,
and make them see the importance of developing the resources of
the country.
• Introducing them to European ways of life, would change their
tastes and desires, and create a demand for British goods, for
Indians would begin to appreciate and buy things that were
produced in Europe.
• Following the 1854 Despatch, several measures were introduced by
the British. Education departments of the government were set up
to extend control over all matters regarding education. Steps were
taken to establish a system of university education Q Source: Improvisation: Page 98: History Standard 8th NCERT: Our

UPSC Paper 1 Mock Test - 13 - Question 5

The Biomolecule Sequencer experiment of NASA intends to demonstrate that
1. Independent genes can be preserved and harvested even in extreme situations where life may not be possible.
2. DNA sequencing is feasible in an orbiting spacecraft.
Which of the above is/are correct?

Detailed Solution for UPSC Paper 1 Mock Test - 13 - Question 5

Justification & Learning: NASA for the first time has successfully
sequenced DNA in space aboard the International Space Station (ISS).
• The genome sequencing was undertaken for the first time in
microgravity as part of the Biomolecule Sequencer experiment
performed by NASA astronaut Kate Rubins.
• It is not about survival of genes in extreme conditions, so 2 is
wrong.
• This experiment provides a way to sequence DNA in space which
can help astronauts to diagnose an illness.
• Besides, it will also help them identify microbes growing in the ISS
to determine whether or not they represent a health threat.
• The future explorers can potentially use the technology to identify
DNA-based life forms beyond Earth.

UPSC Paper 1 Mock Test - 13 - Question 6

Concerns over the use and production of Polyethylene Terephthalate (PET) have been raised because
1. No known species of fungi or bacteria can degrade PET.
2. Manufacturing PET resin generates more toxic emissions of nickel and Benzene than in producing same amount of glass.
Which of the above is/are correct?

Detailed Solution for UPSC Paper 1 Mock Test - 13 - Question 6

Justification: It is the most common thermoplastic polymer resin of
the polyester family and is used in fibres for clothing, containers for
liquids and foods, thermoforming for manufacturing, and in
combination with glass fibre for engineering resins.
Statement 1: At least one species of bacterium in the genus Nocardia can
degrade PET with an esterase enzyme.
Japanese scientists have isolated a bacterium Ideonella sakaiensis that
possesses two enzymes which can break down the PET into smaller
pieces that the bacterium can digest. So, 1 is incorrect.
Statement 2: Manufacturing PET resin generates more toxic emissions
(nickel, ethyl benzene, ethylene oxide, benzene) than manufacturing
glass. Producing a 16 oz. PET bottle generates more than 100 times the
toxic emissions to air and water than making the same size bottle out of
glass.

either Party to carry out any joint activity, nor does it oblige the parties
to supply troops in case of a requirement by the other party. So, 1 will
clearly be wrong.
Statement 2: USA has already declared India a major defence partner,
but not a “strategic” defence partner status which is enjoyed by its closest
allies obliging the USA to share cutting-edge technology with them. Since
India is not a strategic partner, 2 will be wrong.

basing arrangements, as clarified by the Minister of Defence. So, 3 is
wrong.

UPSC Paper 1 Mock Test - 13 - Question 12

The “Sovereignty” of India means
1. No external power can dictate the government of India.
2. Citizens cannot be discriminated against on any grounds.
3. There is absolute freedom of speech and expression for Indian citizens.
4. All citizens have equal economic rights.
Select the correct answer using the codes below.

Detailed Solution for UPSC Paper 1 Mock Test - 13 - Question 12

Justification: Sovereignty simply implies that India is a state that takes
its own decisions ultimately guided by the people. No external agency
dictates terms to India. So, 1 is correct.
Statement 2: However, the notion of sovereignty does not seep into the
framework of all democratic rights. For e.g. a sovereign state might very
well discriminate between its citizens, for e.g. as Pakistan does with all
non-Muslims.
Statement 3: Same applies for freedom of speech and expression. A
sovereign state may very well restrict freedom of speech, as it is not an
absolute right, even though it is vital to a democracy.
Statement 4: This is only possible in an economic democracy.

The Aligarh movement laid great stress on

Detailed Solution for UPSC Paper 1 Mock Test - 13 - Question 16

Learning: Sir Syed launched the Aligarh Movement of which Aligarh
was the center.
He had two immediate objectives in mind: to remove the state of
misunderstanding and tension between the Muslims and the new British
government, and to induce them to go after the opportunities available
under the new regime without deviating in any way from the
fundamentals of their faith.

UPSC Paper 1 Mock Test - 13 - Question 17

Which of the following type of bills can be passed in a joint sitting of the Parliament? 

Detailed Solution for UPSC Paper 1 Mock Test - 13 - Question 17

Learning: Any ordinary law needs to be passed by both the Houses. But
if there is a difference between the two Houses, the final decision is taken
in a joint session in which members of both the Houses sit together.
Because of the larger number of members, the view of the Lok Sabha is
likely to prevail in such a meeting.
But, Lok Sabha exercises more powers in money matters. Once the Lok
Sabha passes the budget of the government or any other money related
law, the Rajya Sabha cannot reject it. The Rajya Sabha can only delay it
by 14 days or suggest changes in it. The Lok Sabha may or may not
accept these changes. There is no provision for joint sitting in such cases.

in 1961, and was largely conceived by India's first prime minister,
Jawaharlal Nehru; Indonesia's first president, Sukarno; Egypt's second
president, Gamal Abdel Nasser; Ghana's first president Kwame
Nkrumah; and Yugoslavia's president, Josip Broz Tito.
All five leaders were prominent advocates of a middle course for states in
the Developing World between the Western and Eastern Blocs in the
Cold War.
Statement 2: Because the Non-Aligned Movement was formed as an
attempt to thwart the Cold War, it has struggled to find relevance since
the Cold War ended. Belarus is the only member of the Movement in
Europe.
As the world has become more polarised between USA and China, hardly
any nation has been able to keep itself aloof from involving itself with
these major powers.

wanted to combine elements of modern Western civilisation with what
he saw as the best within Indian tradition.
Statement 2: Tagore emphasised the need to teach science and
technology at Santiniketan, along with art, music and dance. Tagore was
of the view that creative learning could be encouraged within a natural

UPSC Paper 1 Mock Test - 13 - Question 24

Consider the following about Blue-Green Algae.
1. They are a group of photosynthetic bacteria.
2. Warm and nutrient rich water promote their growth.
3. They are a “keystone species” throughout the Arabian and Indian Ocean.
4. Excessive growth of Blue-green algae can deplete the amount of oxygen in the water and threaten aquatic life.
Select the correct answer using the codes below.

Detailed Solution for UPSC Paper 1 Mock Test - 13 - Question 24

Justification: Statement 1: Cyanobacteria, formerly called "blue-green
algae" are relatively simple, primitive life forms closely related to
bacteria. Typically much larger than bacteria, they photosynthesize like
algae. Depending upon the species, cyanobacteria can occur as single
cells, filaments of cells, or colonies.
Statement 2: Nutrient-rich bodies of water such as some lakes or ponds
may support rapid growth of cyanobacteria. With the right conditions, a
"clear" body of water can become very turbid with green, blue-green or
reddish-brown colored algae within just a few days. High concentrations
of an alga species in a water body form "blooms."
Statement 3: Blue-green algae, like true algae, make up a portion of the
phytoplankton in many water bodies. However, blue-green algae are
generally not eaten by other aquatic organisms, and thus are not an
important part of the food chain.
“Keystone species” are crucial parts of the food chain; without them
there will be a partial collapse of the food chain. So, 3 is incorrect.
Statement 4: Blue-green algae blooms can alter lake ecosystems by:
• reducing oxygen levels
• preventing the growth of beneficial algae
• producing toxins that are directly harmful to fish and other
organisms
People may become ill after swimming or water skiing in lakes with toxic
blue-green algae.

Detailed Solution for UPSC Paper 1 Mock Test - 13 - Question 25

Justification: Statement 1: The body provides overall policy and
regulatory guidance on issues relating to agriculture, livestock, food
safety, nutrition, rural development and natural resource management
in FAO.
Statement 2: It has no such authority and it does not concern itself with
agricultural trade regulation. It instead reviews major agricultural and
nutritional problems and proposes concerted action by FAO’s Member
Nations.
Statement 3: Established in 1971 (WTO in 1995), the Committee has over
100 Member Nations and generally meets every two years, but may hold
additional sessions if needed.

Which of the following play a role in the Nitrogen cycle on earth?
1. Blue-green algae
2. Lightning
3. Uptake of soil nutrients by plants
4. Terrestrial Food chain

Select the correct answer using the codes below.

Detailed Solution for UPSC Paper 1 Mock Test - 13 - Question 26

Justification: Nitrogen is one of the essential constituents of all living
organisms as part of proteins, chlorophyll, nucleic acids and vitamins.
• The atmospheric nitrogen cannot be taken directly by plants and
animals.
Statement 1: Certain bacteria and blue green algae present in the soil fix
nitrogen from the atmosphere and convert into compounds of nitrogen
Statement 2: Lightning also fixes atmospheric nitrogen (role shown in
the diagram).
Statement 3 and 4: Nitrogen is one of the essential constituents of all
living organisms as part of proteins, chlorophyll, nucleic acids and
vitamins.
• The atmospheric nitrogen cannot be taken directly by plants and
animals. Once nitrogen is converted into these usable compounds,
it can be utilised by plants from the soil through their root system.
• Nitrogen is then used for the synthesis of plant proteins and other
compounds. Animals feeding on plants get these proteins and
other nitrogen compounds.
• When plants and animals die, bacteria and fungi present in the soil
convert the nitrogenous wastes into nitrogenous compounds to be
used by plants again. Certain other bacteria convert some part of
them to nitrogen gas which goes back into the atmosphere.
• As a result, the percentage of nitrogen in the atmosphere remains
more or less constant.

Consider the following about Essential Services Maintenance Act (ESMA).
1. The Act can be used to call off worker’s strikes both in public and private sector if it disrupts essential services.
2. Only the Central government can order restoration of essential services in India.
Which of the above is/are correct?

Detailed Solution for UPSC Paper 1 Mock Test - 13 - Question 27

Justification: The Act includes a long list of “essential services” in its
charter - ranging from post and telegraph, through railway, airport and
port operations - and it prohibits the key employees in these services
from striking.
The Act also allows states to enact their own ESMA and choose the
essential services on which to enforce Esma.
Statement 2: Although it is Central law, its execution can be done by the
State governments and UT governments too. For e.g. Delhi government
has invoked the ESMA to declare a nurse’s strike illegal.
Recently the AP government declared IT to be an essential service, which
allows it to call off illegitimate strikes in the IT sector.

broad channel that separates the northern and central Maldives from the
southern atolls and is one of the broadest channels between the atolls of
Maldives.
