Past Questions
Which one of the following category is not included in the National Air Quality Index?
A)
Very poor
B)
Severe
C)
Moderately polluted
D)
Highly polluted
The National Air Quality Index (AQI) in India is a tool used to communicate the quality of air to the public. It categorizes air quality into six distinct levels based on the concentration of pollutants. The official categories are:
1. Good (0-50)
2. Satisfactory (51-100)
3. Moderate (101-200)
4. Poor (201-300)
5. Very Poor (301-400)
6. Severe (401-500)
Analyzing the options:
- Option (a) 'Very poor' is a valid category.
- Option (b) 'Severe' is a valid category.
- Option (c) 'Moderately polluted' refers to the 'Moderate' category (though phrased slightly differently, it aligns with the index's scale).
- Option (d) 'Highly polluted' is NOT a term used in the official National AQI classification. The index uses 'Poor', 'Very Poor', and 'Severe' to describe high levels of pollution, but never 'Highly polluted'.
A cave found in Phawngpui tlang was -
A)
Tialpapuk
B)
Sur puk
C)
Tialpari puk
D)
Pukzing
Phawngpui, also known as the Blue Mountain, is the highest peak in Mizoram. It is renowned for its biodiversity and geological features. Tialpapuk is a well-known cave located on Phawngpui tlang. In Mizo, 'Puk' means cave. While Mizoram has numerous caves (such as those in the Vairengte or Champhai regions), Tialpapuk is specifically associated with the Phawngpui area. The other options provided (Sur puk, Tialpari puk, Pukzing) are either not associated with this specific peak or are not the primary recognized cave of that location in standard Mizoram GK texts.
Puma Zai was replaced by -
A)
Tlanglam zai
B)
Chawngchen zai
C)
Nilen zai
D)
Dawn zai
In the history of Mizo traditional music and folk songs, 'Puma Zai' was a traditional form of singing. Over time, as the cultural and musical preferences of the Mizo people evolved, Puma Zai was replaced by 'Nilen zai'. Nilen zai represents a shift toward a different style of melodic expression and lyrical structure within the Mizo cultural heritage. Tlanglam zai, Chawngchen zai, and Dawn zai are other forms of Mizo songs or chants, but they served different purposes (such as war songs or specific ritualistic chants) and did not specifically replace the Puma Zai tradition.
In Mizo folktales, a well-known magical object called ‘Bahhnukte’ is found in -
A)
Rairahtea thawnthu
B)
Chhura leh Naa thawnthu
C)
Nuchhimi thawnthu
D)
Sichangneii thawnthu
In Mizo folklore, 'Bahhnukte' refers to a magical object (often described as a magical bag or pouch) that possesses the power to produce food or wealth. This magical object is a central plot element in the story of 'Rairahtea' (Rairahtea thawnthu), where the protagonist uses the object to overcome poverty or trick others.
- Option (b) 'Chhura leh Naa' is a fable involving a clever man and a tiger, focusing on wit rather than magical objects like Bahhnukte.
- Option (c) 'Nuchhimi' is a tragic tale of a girl and her devotion/suffering.
- Option (d) 'Sichangneii' is another traditional tale, but it does not feature the specific magical object 'Bahhnukte' as its primary motif.

In 1992, the corporation was renamed as the Power Grid Corporation of India Limited, commonly known as POWERGRID. It is a Maharatna Public Sector Enterprise and is the central transmission utility of India.
Analysis of other options:
- Option (a) 'National Electricity Transmission Corporation' is not a recognized entity in this context.
- Option (c) 'Power Trading Corporation' (PTC India) is a separate entity focused on the trading of electricity, not the physical construction and maintenance of transmission lines.
- Option (d) 'National Electricity Regulatory Commission' refers to regulatory bodies (like CERC or SERCs) that set tariffs and rules, rather than operating the transmission infrastructure.
Several plants are sensitive to ozone and contribute as an indicator of air pollution. Ozone enters leaves through the microscopic pores of-
A)
Xylem
B)
Phloem
C)
Stomata
D)
Macropores
Step-by-step reasoning: 1. The question asks for the microscopic pores through which ozone (a gaseous pollutant) enters the leaves of a plant. 2. Stomata are tiny pores located primarily on the epidermis of leaves that regulate gas exchange (taking in carbon dioxide and releasing oxygen and water vapor). 3. Because ozone is a gas, it enters the plant tissue via these same stomatal openings during normal respiration and photosynthesis processes. 4. Once inside, ozone reacts with the internal leaf tissues, causing oxidative stress and damage, which makes certain plants useful as bio-indicators of air pollution.
Why other options are incorrect:
- Xylem (a) and Phloem (b) are vascular tissues used for the transport of water, minerals, and nutrients throughout the plant; they are not external pores for gas entry.
- Macropores (d) generally refer to larger spaces in soil structure, not the microscopic gas-exchange pores of a leaf.
The DRDO Centre for Artificial Intelligence and Robotics (CAIR) is located in-
A)
Delhi
B)

D)
Kanpur
The Centre for Artificial Intelligence and Robotics (CAIR) is a premier laboratory of the Defence Research and Development Organisation (DRDO). It is located in Bengaluru, Karnataka. CAIR focuses on the research and development of AI, robotics, and autonomous systems for defense applications.
Analysis of other options:
- Delhi: While DRDO headquarters (DRDO Bhavan) is located in New Delhi, CAIR specifically is not based there.
- Mumbai: Mumbai hosts other DRDO labs (such as HFAL), but not CAIR.
- Kanpur: Kanpur is home to other research institutions and DRDO-related collaborations, but CAIR is situated in the technology hub of Bengaluru.
The first Scientific Policy Resolution in India was adopted in the year -
A)
1971
B)
1949
C)
1958
D)
1963
The first Scientific Policy Resolution (SPR) was adopted by the Government of India in 1958. This landmark resolution aimed to achieve a 'scientific temper' among the people and to promote the application of science and technology for the socio-economic development of the country. It laid the foundation for the institutional framework of science and technology in post-independence India.
Analysis of other options:
- 1949: This was shortly after independence; while scientific institutions were being planned, the formal policy resolution had not yet been adopted.
- 1963: This year is associated with the establishment of various research centers, but not the first SPR.
- 1971: This is far beyond the initial policy-making phase of the early republic.

It was founded to provide formal theological training for local Mizo ministers and leaders to support the growing Christian church in the region. The other dates provided (1902, 1907, 1909) correspond to earlier periods of missionary activity and the establishment of basic education/mission stations, but the specific institution for theological training was formalized in 1919.
In traditional Mizo society the religious rite ‘Kawngpui siam’ is observed every year before the commencement of -
A)
Pawl kut
B)
Mim kut
C)
Chapchar kut
D)
Khuangchawi
In traditional Mizo society, 'Kawngpui siam' (literally meaning 'making the main road/path') was a ritualistic practice performed before the commencement of Chapchar Kut. Chapchar Kut is the most significant spring festival of the Mizos, celebrated after the completion of 'jhum' (slash-and-burn) clearing. The 'Kawngpui siam' rite was observed to clear the paths and symbolically prepare the community for the festivities and the agricultural cycle, ensuring that the spirits were appeased and the way was open for the celebration.
Other options are incorrect because:
- Pawl kut is a harvest festival celebrated after the gathering of crops.
- Mim kut is a festival associated with the remembrance of the dead and the transition of seasons.
- Khuangchawi is a grand feast/ritual involving the beating of the drum, usually performed for social status or specific religious offerings, rather than a seasonal path-clearing rite.
The first recipient of the Padma Shri Award among the women from Mizoram was -
A)
Khawlkungi
B)
Nuchhungi Renthlei
C)
Buangi Sailo
D)
Lalsangzuali Sailo
Nuchhungi Renthlei was the first woman from Mizoram to be honored with the Padma Shri award. She was recognized for her exceptional contributions to social work and the upliftment of the community in Mizoram.

She served as the Deputy Operations Director for the mission, contributing significantly to the navigation and trajectory design that allowed India to become the first nation to reach Martian orbit in its maiden attempt. While she has contributed to other projects, her primary claim to fame in competitive exams and general knowledge is her leadership role in the Mars Orbiter Mission.
Analysis of other options:
- b. Chandrayaan-3: While many ISRO scientists worked on this, Ritu Karidhal is most specifically associated with the MOM mission in standard academic contexts.
- c. GSAT-9: This is a communication satellite; while ISRO manages it, it is not the primary mission associated with Karidhal's public profile.
- d. LVM3 rocket: This is a launch vehicle (hardware), whereas Karidhal's expertise lies in mission operations and navigation.
The first Indian to take over as Superintendent of Lushai Hills was -
A)
S.N.Barkataki
B)
Brojo Nath Saha
C)
GN Bardoloi
D)
Rup Nath Brahma
The Lushai Hills (now Mizoram) were administered by British officers for several decades. Following India's independence in 1947, the administration transitioned to Indian officers. S.N. Barkataki was the first Indian to be appointed as the Superintendent of the Lushai Hills, marking a significant shift in the administrative history of the region from British to Indian governance. The other options listed (Brojo Nath Saha, GN Bardoloi, and Rup Nath Brahma) were prominent figures in the politics and administration of Northeast India (particularly Assam), but they did not serve as the first Indian Superintendent of the Lushai Hills.
The famous East- West War called ‘Chhak leh Thiang Indo’ was fought between -
A)
Vanhnuailiana vs Thawmvunga
B)
Lallianvunga vs Lalpuithanga
C)
Vuta and Manga vs Lalsavunga
D)
Rolura vs Vuta
The 'Chhak leh Thiang Indo' (War of the East and West) is a significant conflict in Mizo history. It was a power struggle for supremacy between two powerful chiefs: Vanhnuailiana (representing the West/Thiang) and Thawmvunga (representing the East/Chhak). This war is well-documented in Mizo oral traditions and historical records as a clash between two of the most influential chiefs of the era.
Analysis of other options:
- Option b: Lallianvunga and Lalpuithanga were chiefs, but they are not the primary figures of the Chhak leh Thiang Indo.
- Option c: Vuta and Manga were powerful chiefs, but their conflicts were distinct from the specific East-West war involving Vanhnuailiana and Thawmvunga.
- Option d: Rolura and Vuta were also prominent figures, but they do not define this specific historical conflict.
The Chaff technology developed by DRDO protects fighter aircrafts from-
A)
Hostile radar threats
B)
Cyber threats
C)
Biological threats
D)
Space debris
Chaff is a radar countermeasure that consists of a cloud of small, thin pieces of aluminum, metallized glass fiber, or plastic. When deployed by a fighter aircraft, these particles reflect radar waves, creating a large 'false target' or a 'cloud' on the enemy's radar screen. This masks the actual position of the aircraft, making it difficult for hostile radar systems to track or lock onto the plane for missile guidance.
Why other options are incorrect:
- b. Cyber threats: These are countered by firewalls, encryption, and cybersecurity software, not physical particles.
- c. Biological threats: These are countered by vaccines, PPE, and bio-defense protocols.
- d. Space debris: This is managed through orbital tracking and debris removal technologies, not by deploying reflective clouds from aircraft.
It is anetwork that is constructed by using public wires/network usually the internet to connect to a private network -
A)
VPN
B)
WAN
C)
LAN
D)
MAN
The question describes a Virtual Private Network (VPN). A VPN creates a secure, encrypted 'tunnel' over a public network (typically the internet) to allow users to access a private network as if they were directly connected to it.
Here is why the other options are incorrect:
- b. WAN (Wide Area Network): This is a broad category of networks that cover large geographical areas. While a VPN often operates over a WAN, a WAN itself is not specifically defined as a tool to connect to a private network via public wires.
- c. LAN (Local Area Network): This is a network restricted to a small area, like a single building or home, and typically uses private cabling rather than public wires.
- d. MAN (Metropolitan Area Network): This is a network that connects users within a geographic area larger than a LAN but smaller than a WAN (e.g., a city), and does not inherently imply the use of public wires to access a private network.
In Mizo marriage, the principal bride price is known as -
A)
Sum zan jut
B)
Pusum
C)
Sumpui
D)
Manpui
In traditional Mizo society, marriage involves the payment of a bride price. The principal or main bride price is known as 'Pusum'. This is the primary payment made by the groom's family to the bride's family to formalize the marriage.
Breakdown of other terms:
- 'Sum zan jut' refers to additional payments or supplementary gifts given during the marriage process.
- 'Sumpui' and 'Manpui' are not the standard technical terms used to describe the principal bride price in the context of traditional Mizo customary law.
Grouping of villages was introduced in Mizoram from -
A)
1966
B)
1968
C)
1967
D)
1969
The 'Grouping of Villages' policy was implemented in Mizoram in 1967. This policy was introduced by the Government of India and the state administration during a period of insurgency to isolate the Mizo National Front (MNF) rebels from the civilian population. Under this scheme, small, scattered villages were forcibly relocated and consolidated into larger 'grouped villages' to facilitate better security surveillance and to prevent the villagers from providing food, shelter, or intelligence to the underground insurgents. This policy caused significant hardship to the local population and is a well-documented event in the modern history of Mizoram.
For selection of new site or village -
A)
Itmust be selected by ramhual and sadawt by sleeping one night at the propose site taking with them witha cock. If the cock crow before dawn, the site would be considered suitable.
B)
It must have to be selected by the elders which they did by sleeping one night at the propose site taking with them a cock. If the cock did not crow before dawn, the site would be considered not suitable.
C)
It must have to be selected by only ‘ramhual’ which they did by sleeping one night at the propose site taking with them a cock
In traditional Mizo society, the selection of a new village site was a spiritual and ritualistic process. The 'Ramhual' (village explorers/scouts) and 'Sadawt' (those who scouted the land) were responsible for this task. The traditional belief held that to determine if a site was auspicious or 'suitable' for settlement, the scouts would spend a night at the proposed location with a cock. If the cock crowed before the actual dawn, it was interpreted as a positive omen or a sign of approval from the spirits/nature, indicating that the site was suitable for the establishment of the village. Option (b) is incorrect because it focuses on 'elders' generally and suggests a negative condition. Option (c) is incorrect because it excludes the 'sadawt' and provides an incomplete description of the ritual outcome.
The only approved genetically modified (GM) crop for cultivation in India is-
A)
Bttomato
B)
Golden rice
C)
Btcotton
D)
GM Canola
Step-by-step reasoning: 1. Genetically Modified (GM) crops are plants whose DNA has been modified using genetic engineering techniques. 2. In India, the Genetic Engineering Appraisal Committee (GEAC), under the Ministry of Environment, Forest and Climate Change, is the regulatory body that approves the commercial release of GM crops. 3. Bt cotton (Bacillus thuringiensis cotton) was approved for commercial cultivation in India in 2002. It is engineered to be resistant to the bollworm pest. 4. While other GM crops like Bt Brinjal and DMH-11 Mustard have been discussed or approved at various stages of trials/regulatory review, Bt cotton remains the only GM crop currently approved for large-scale commercial cultivation in Indian fields. 5. Analysis of other options: (a) Bt tomato is not approved for cultivation in India. (b) Golden rice is a biofortified crop developed to combat Vitamin A deficiency; while tested in some countries, it is not approved for commercial cultivation in India. (d) GM Canola is widely grown in countries like Canada and the USA, but not approved for cultivation in India.
Sibuta Lung is situated at the outskirt of -
A)
Maubuang village
B)
Muallungthu village
C)
Samlukhai village
D)
Tachhip village
Sibuta Lung is a significant megalithic site located on the outskirts of Tachhip village in Mizoram. It is known for its historical and archaeological importance, featuring large stone structures (megaliths) that provide insight into the ancient settlement patterns and cultural practices of the people in the region. The other villages mentioned (Maubuang, Muallungthu, and Samlukhai) are not associated with the Sibuta Lung site.
