Question 1 of 30
1. Question
1 pointsWhich one of the following foreign travellers elaborately discussed about diamonds and diamond mines of India?
Correct
Solution: B
Jean-Baptiste Tavernier (1605-1689) was a French explorer and merchant. He was the first European to describe the diamond mines in India.
In 1676, Tavernier published an account of his six journeys to India and Persia from 1631 to 1668 in Les Six Voyages de Jean-Baptiste Tavernier (translated into English in 1678 as The Six Voyages of John Baptista Tavernier).
Though Tavernier provided a wealth of information about his travels and work, he did not record the details of his important transactions. It is likely that he did not want to reveal the source and the price of gems that he purchased since that information could negatively affect his business.

Question 2 of 30
2. Question
1 pointsConsider the following statements regarding Acute Encephalitis Syndrome (AES)
- It is a basket term used for referring to hospitals, children with clinical neurological manifestation that includes mental confusion, disorientation, convulsion, delirium, or coma.
- It can be caused by various agents including bacteria, fungi, virus and many other agents.
- Nipah virus, Zika virus are also found as causative agents for AES.
Which of the statements given above is/are correct?
Correct
Solution: D
Acute Encephalitis Syndrome (AES) has fanned fear among the villagers and health officials of Bihar’s Muzaffarpur and neighboring districts amid the novel corona virus disease (COVID-19) lockdown.
At least three children have reportedly died of the disease, locally known as chamki bukhar, in 2020.
About AES:
- Acute encephalitis syndrome is a basket term used for referring to hospitals, children with clinical neurological manifestation that includes mental confusion, disorientation, convulsion, delirium, or coma.
- Meningitis caused by virus or bacteria, encephalitis (mostly Japanese encephalitis) caused by virus, encephalopathy, cerebral malaria, and scrub typhus caused by bacteria are collectively called acute encephalitis syndrome.
- The disease most commonly affects children and young adults and can lead to considerable morbidity and mortality.
Symptoms:
It is characterized as acute-onset of fever and a change in mental status (mental confusion, disorientation, delirium, or coma) and/or new-onset of seizures in a person of any age at any time of the year.
Cause of the disease:
Acute Encephalitis Syndrome (AES) is considered a very complex disease as it can be caused by various agents including bacteria, fungi, virus and many other agents.
Viruses are the main causative agents in AES cases, although other sources such as bacteria, fungus, parasites, spirochetes, chemicals, toxins and noninfectious agents have also been reported over the past few decades.
Japanese encephalitis virus (JEV) is the major cause of AES in India (ranging from 5%-35%).
Nipah virus, Zika virus are also found as causative agents for AES.
How is it related to litchi fruits? How it affects?
In India, AES outbreaks in north and eastern India have been linked to children eating unripe litchi fruit on empty stomachs.
Unripe fruit contain the toxins hypoglycin A and methylenecyclopropylglycine (MCPG), which cause vomiting if ingested in large quantities. Hypoglycin A is a naturally occurring amino acid found in the unripened litchi that causes severe vomiting (Jamaican vomiting sickness), while MCPG is a poisonous compound found in litchi seeds.
Why it affects undernourished children?
- Blood glucose falls sharply causing severe brain malfunction (encephalopathy), leading to seizures and coma, and death in many cases.
- This is because under-nourished children lack sufficient glucose reserve in the form of glycogen and the production of glucose from non-carbohydrate source is blocked midway leading to low blood sugar level.
- This causes serious brain function derangement and seizures.
Measures needed:
- Increase access to safe drinking water and proper sanitation facilities.
- Improve nutritional status of children at risk of JE/AES.
- Preparative measures to be in place before the possible outbreaks.
- Vector control.
- Better awareness generation among children, parents through Anganwadi workers, ANMs etc.

Which of the statements given above is/are correct?
Correct
Solution: A
What is ANtarctic Impulsive Transient Antenna or ANITA?
What to study?
For Prelims and Mains: ANITA- objectives m functions and findings.
Context: The news that a NASA experiment has indicated the possibility of a parallel universe has created headlines across the world. WIth this, ANtarctic Impulsive Transient Antenna or ANITA has suddenly come into the limelight as the cosmic-ray shower that is key to the new discovery was a part of NASA’s ANITA and IceCube experiment taking place in Antarctica.
What is ANITA?
Designed by NASA, the ANITA instrument is a radio telescope which is used to detect ultra-high energy cosmic-ray neutrinos from a scientific balloon flying over Antarctica.
ANITA is the first NASA observatory for neutrinos of any kind.
It involves an array of radio antennas attached to a helium balloon which flies over the Antarctic ice sheet at 37,000 meters.
How many ANITAs?
- ANITA-I was launched from McMurdo, Antarctica in 2006.
- ANITA-II, a modified instrument with 40 antennas, was launched from McMurdo Station in 2008.
- ANITA-III, which was equipped with systems to improve sensitivity by a factor of 5–10, was launched in December 2014.
- ANITA-IV was launched in December 2016 and it was loaded with tunable notch filters and an improved trigger system.
Facts for Prelims:
The neutrinos have energies on the order of 1018 eV and they are capable of producing radio pulses in the ice because of the Askaryan effect.
What are neutrinos?
Neutrinos are high-energy particles that pose no threat to us and pass through most solid objects without anyone even noticing.
Neutrinos constantly bombard Earth and as per some estimates emerging from studies, 100 trillion neutrinos pass through your body every second.
Do they interact with matter?
Rarely do they interact with matter. But if they do smash into an atom, they produce a shower of secondary particles we can detect, which allows us to probe where they came from in the universe.

- Terrestrial, Aerial and Marine Navigation
- Disaster Management
- Precise Timing
- Mapping and Geodetic data capture
Select the correct answer using the code given below:
Correct
Solution: D
What is NAVIC?
The Indian Regional Navigation Satellite System (IRNSS), with an operational name of Navigation with Indian Constellation (NavIC) is an independent regional navigation satellite system designed to provide position information in the Indian region and 1500 km around the Indian mainland.
Services provided:
IRNSS would provide two types of services, namely Standard Positioning Services available to all users and Restricted Services (an encrypted one) provided to authorised users (including the military).
NavIC-based vehicle trackers system has been made compulsory to all commercial vehicles.
Its applications include:
- Terrestrial, Aerial and Marine Navigation.
- Disaster Management.
- Vehicle tracking and fleet management.
- Integration with mobile phones.
- Precise Timing.
- Mapping and Geodetic data capture.
- Terrestrial navigation aid for hikers and travellers.
- Visual and voice navigation for drivers.
How many satellites does NAVIC consist of?
It is a regional system and so its constellation will consist of seven satellites.
Three of these will be geostationary over the Indian Ocean, i.e., they will appear to be stationary in the sky over the region, and four will be geosynchronous – appearing at the same point in the sky at the same time every day. (two additional satellites on ground as stand-by.)
This configuration ensures each satellite is being tracked by at least one of fourteen ground stations at any given point of time, with a high chance of most of them being visible from any point in India.

IRNSS would provide two types of services, namely Standard Positioning Services available to all users and Restricted Services (an encrypted one) provided to authorised users (including the military).
NavIC-based vehicle trackers system has been made compulsory to all commercial vehicles.
Its applications include:
- Terrestrial, Aerial and Marine Navigation.
- Disaster Management.
- Vehicle tracking and fleet management.
- Integration with mobile phones.
- Precise Timing.
- Mapping and Geodetic data capture.
- Terrestrial navigation aid for hikers and travellers.
- Visual and voice navigation for drivers.
How many satellites does NAVIC consist of?
It is a regional system and so its constellation will consist of seven satellites.
Three of these will be geostationary over the Indian Ocean, i.e., they will appear to be stationary in the sky over the region, and four will be geosynchronous – appearing at the same point in the sky at the same time every day. (two additional satellites on ground as stand-by.)
This configuration ensures each satellite is being tracked by at least one of fourteen ground stations at any given point of time, with a high chance of most of them being visible from any point in India.

Question 13 of 30
13. Question
1 pointsConsider the following statements regarding Bio fortification
- Fortification is the practice of deliberately increasing the content of an essential micronutrient, i.e. vitamins and minerals (including trace elements) in a food.
- It is legally banned in India.
- Bio fortification of rice, beans, sweet potato and legumes is possible.
Which of the statements given above is/are correct?
Correct
Solution: A
Fortification is the practice of deliberately increasing the content of an essential micronutrient, i.e. vitamins and minerals (including trace elements) in a food, so as to improve the nutritional quality of the food supply and provide a public health benefit with minimal risk to health.
Biofortification is the process by which the nutritional quality of food crops is improved through agronomic practices, conventional plant breeding, or modern biotechnology.
Biofortification differs from conventional fortification in that bio fortification aims to increase nutrient levels in crops during plant growth rather than through manual means during processing of the crops.
Biofortification may therefore present a way to reach populations where supplementation and conventional fortification activities may be difficult to implement and/or limited.
There is no legal ban on bio-fortification in India.
Examples of bio fortification projects include:
- iron-biofortification of rice, beans, sweet potato, cassava and legumes;
- zinc-biofortification of wheat, rice, beans, sweet potato and maize;
- provitamin A carotenoid-biofortification of sweet potato, maize and cassava; and
- amino acid and protein-biofortification of sourghum and cassava.

- Once every 29 days, the Moon traverses the geotail for about six days.
- The region exists as a result of the interactions between the Sun and Earth.
Which of the statements given above is/are correct?
Correct
Solution: C
Geotail
An instrument on Chandrayaan-2, CLASS (Chandrayaan 2 Large Area Soft X-ray
Spectrometer), designed to detect signatures of elements in the Moon’s soil, had detected charged particles during the mission.
What is Geotail?
A region in space that allows the best observations. The region exists as a result of the interactions between the Sun and Earth.
How is it formed?
- The Sun emits the solar wind, which is a continuous stream of charged particles.
- These particles are embedded in the extended magnetic field of the Sun. Since the Earth has a magnetic field, it obstructs the solar wind plasma.
- This interaction results in the formation of a magnetic envelope around Earth.
- On the Earth side facing the Sun, the envelope is compressed into a region that is approximately three to four times the Earth radius.
- On the opposite side, the envelope is stretched into a long tail, which extends beyond the orbit of the Moon.
It is this tail that is called the geotail.
- Once every 29 days, the Moon traverses the geotail for about six days.

1 pointsConsider the following statements Asteroid Impact Deflection Assessment experiment
- Hera mission is the European component of the mission to slam a spacecraft into an asteroid.
- Double Asteroid Redirection Test (DART) will be conducted by NASA and will target Didymos, a moonlet.
Which of the statements given above is/are correct?
Correct
Solution: A
Hera mission
The European Space Agency (ESA) had approved the budget of Hera, the European component of the mission to slam a spacecraft into an asteroid.
What is Hera?
Hera is the European contribution to an international double-spacecraft collaboration.
Hera is named after the Greek goddess of marriage.
How is it planned?
Due to launch in 2024, Hera would travel to a binary asteroid system – the Didymos pair of near-Earth asteroids.
NASA will first perform a kinetic impact on the smaller of the two bodies, then Hera will follow-up with a detailed post-impact survey that will turn this grand-scale experiment into a well-understood and repeatable planetary defence technique.
What is DART mission?
Double Asteroid Redirection Test (DART) will target Didymoon as part of its planetary defence programme.
- DART will deliberately crash itself into the moonlet at a speed of approximately 6 km per second, using an onboard camera and autonomous navigation software.
- The collision will change the speed of the moonlet in its orbit around the main body.
Why Didymoon?
- Didymoon was chosen because of its close proximity to Earth and its size. Didymoon is small and in a tight enough 12-hour orbit around its parent, that its orbital period can indeed be shifted in a measurable way.
Significance:
- DART and Hera were conceived together as part of the international ‘Asteroid Impact Deflection Assessment’ experiment.
Why we need a planetary defence mechanism?
- There are around 25,000 near-Earth objects (NEOs) that orbit the Sun on a trajectory that brings them close to our planet’s orbit. Certain near-Earth objects have been classified as “potentially hazardous”.
- As of now, there are about 900 near-Earth objects measuring more than 1 km. An impact from one of these NEOs can bring devastating effects to Earth.
- That is why scientists are working on a number of planetary protection initiatives to deflect asteroids if they threaten to impact the Earth.

1 pointsConsider the following statements regarding Virtual human-NEONs
- It has been developed by SpaceX.
- NEONs are developed to become intelligent enough to be fully autonomous, showing emotions, learning skills, creating memories, and being intelligent on their own.
Which of the statements given above is/are correct?
Correct
Solution: B
Virtual human’ NEONs
The first project of Samsung’s Star Labs, NEONs are being called the world’s first artificial humans.
What are they?
- NEONs are computationally created virtual humans — the word derives from NEO (new) + humaN.
- For now the virtual humans can show emotions when manually controlled by their creators.
- But the idea is for NEONs to become intelligent enough to be fully autonomous, showing emotions, learning skills, creating memories, and being intelligent on their own.
How do they work?
There are two core technologies behind his virtual humans.
- First, there is the proprietary CORE R3 technology that drives the “reality, real time and responsiveness” behind NEONs.
- The next stage will be SPECTRA, which will complement CORE R3 with the “spectrum of intelligence, learning, emotions and memory”.
How could NEONs be used?
NEONs might be the interface for technologies and services.
- They will answer your queries at a bank, welcome you at a restaurant, or read out the breaking news on television at an unearthly hour.
- This form of virtual assistance would be more effective, for example, while teaching languages, as NEONs will be capable of understanding and sympathising.
How are NEONs different from Virtual Assistants?
Virtual Assistants now learn from all the data they are plugged into. NEONs will be limited to what they know and learn. Their leaning could potentially be limited to the person they are catering to, and maybe her friends — but not the entire Internet. They will not be an interface for you to request a song, rather they will be a friend to speak to and share experiences with, says Star Labs.

1 pointsConsider the following statements regarding Fuel cell electric vehicles (FCEV)
- A fuel-cell electric vehicle is essentially a hybrid electric vehicle wherein the internal combustion engine is replaced with a fuel-cell stack.
- The fuel cell combines hydrogen and oxygen to generate an electric current, water being the only byproduct.
- Fuel cells generate electricity through an electrochemical process.
Which of the statements given above is/are correct?
Correct
Solution: D
Fuel cell electric vehicles (FCEV)
Supreme Court had directed the government to look into the feasibility of introducing vehicles based on a hydrogen cell technology to deal with air pollution in the National Capital Region.
How does the hydrogen fuel cell work in electric vehicles?
A fuel-cell electric vehicle is essentially a hybrid electric vehicle wherein, the internal combustion engine is replaced with a fuel-cell stack. The onboard sources of power include hydrogen as well as an advanced battery system.
The fuel cell combines hydrogen and oxygen to generate an electric current, water being the only byproduct.
Fuel cells generate electricity through an electrochemical process.
And, there are no moving parts in the fuel cell, so they are more efficient and reliable by comparison.
How is it different from an electric vehicle (EV)?
Unlike a battery-electricity vehicle, it does not store energy and, instead, relies on a constant supply of fuel and oxygen — in the same way that an internal combustion engine relies on a constant supply of petrol or diesel, and oxygen.
Advantages of fuel cells:
- They produce much smaller quantities of greenhouse gases and none of the air pollutants that cause health problems.
- If pure hydrogen is used, fuel cells emit only heat and water as a byproduct.
- They are also energy efficient than traditional combustion technologies.
- Unlike battery-powered electric vehicles, fuel cell vehicles do not need to be plugged in, and most models exceed 300 km of range on a full tank. They are filled up with a nozzle, just like in a petrol or diesel station.
Disadvantages:
- The process of making hydrogen needs energy — often from fossil fuel sources. That has raised questions over hydrogen’s green credentials.
- There are questions of safety — hydrogen is more explosive than petrol.
- Besides, the vehicles are expensive, and fuel dispensing pumps are scarce.

Question 26 of 30
26. Question
1 pointsIf two dice are thrown together, what is the probability of getting a multiple of 3 on one die and multiple of 4 on the other dice?
Correct
Solution: A
The probability of getting a multiple of 3 on one die and multiple of 4 on the other dice (Multiple of three on first dice AND multiple of 4 on the second dice) OR (multiple of 4 on the first dice AND Multiple of three in second dice)
= (2/6 * 1/6) + (1/6 * 2/6)
= 2/6 + 2/6
= 4/6 = 2/3
Incorrect
Solution: A
The probability of getting a multiple of 3 on one die and multiple of 4 on the other dice (Multiple of three on first dice AND multiple of 4 on the second dice) OR (multiple of 4 on the first dice AND Multiple of three in second dice)
= (2/6 * 1/6) + (1/6 * 2/6)
= 2/6 + 2/6
= 4/6 = 2/3

27. Question
1 pointsIn one minute 2/11 of a tank is filled. How much time will it take to fill the remaining part of the tank?
Correct
Solution: B
Part filled in 1 min. = 2/11.
Remaining part = (1- 2/11)= 9/11
Let the required time be x min.
Therefore, 2/11: 9/11:: 1: x ⇒ 2x/11 = (9/11*1) ⇒ x= 4.5.
Incorrect
Solution: B
Part filled in 1 min. = 2/11.
Remaining part = (1- 2/11)= 9/11
Let the required time be x min.
Therefore, 2/11: 9/11:: 1: x ⇒ 2x/11 = (9/11*1) ⇒ x= 4.5.

Question 29 of 30
29. Question
1 pointsBy walking at 3/4th of his usual speed, a man reaches office 20 minutes later than usual. What is his usual time?
Correct
Solution: B
Let his usual speed = S kmph
Let his usual time = t hours
Let the distance to the office = D km
We know that, D = S * t —(1)
New speed is ¾ of usual speed or ¾ S kmph
His new time = t + 20 min or t + (1/3) hour
Distance to the office remains same = D kms
Therefore, D = ¾ S * (3t + 1)/3
Or D = S * (3t + 1)/4 —- (2)
By equating (1) and (2), we get
S * t = (3St +S)/4
Or 4 St = 3St + S
Or S * t = S
Or t =1 hour or 60 min

Question 30 of 30
30. Question
1 pointsDirections for the following (one) item:
Read the following passage and answer the question that follow. Your answer to this question should be based on the passage only.
There has been a significant trend worldwide towards regionalism in government, resulting in a widespread transfer of powers downwards towards regions and communities since 1990s. This process, which involves the creation of new political entities and bodies at a sub-national level and an increase in their content and powers, is known as devolution. Devolution has been characterized as being made up of three factors—political legitimacy, decentralization of authority and decentralization of resources. Political legitimacy here means a mass demand from below for the decentralization process, which is able to create a political force for it to take place. In many cases, decentralization is initiated by the upper tier of government without sufficient political mobilization for it at the grassroots level, and in such cases the decentralization process often does not fulfil its objectives.
30. Which among the following is the most logical, rational and critical inference that can be made from the above passage?
Correct
Solution: C
The passage states that the devolution of power gains legitimacy when there is a demand for it from lower level. It is important to have free expression of the will of the people as the passage states that people at the lower level should be able to create a political force for it which would require active participation at the grassroot level. Hence C.
