Deepor Beel is a Ramsar Site situated in-
A)
Arunachal Pradesh
B)
Assam
C)
Meghalaya
D)
Tripura
Deepor Beel is a permanent freshwater lake located in the Kamrup district of Assam, near the city of Guwahati. It is a critical wetland that serves as a sanctuary for various migratory birds and is a vital habitat for the Asian Elephant. Due to its ecological significance, it was designated as a Ramsar Site (a wetland of international importance) in 2002.
Analysis of other options:
- Arunachal Pradesh: While it has diverse biodiversity, it does not host Deepor Beel.
- Meghalaya: Known for its plateau and rain forests, but Deepor Beel is not located here.
- Tripura: Does not contain this specific Ramsar site.
Looking into a mirror, the clock shows 9 : 30 as the time. Then the actual time is:
A)
2:30
B)
3:30
C)
4:30
D)
6:30
To find the actual time when a mirror image of a clock is given, we use the standard formula for mirror images of clocks. A clock face represents 12 hours, so the sum of the mirror time and the actual time is always 12:00 (or 11:60 to make subtraction easier).
Step-by-step calculation:
1. Mirror Time = 9:30
2. Formula: Actual Time = 11:60 - Mirror Time
3. Calculation:
Hours: 11 - 9 = 2
Minutes: 60 - 30 = 30
4. Result: 2:30
Verification:
- If the time is 2:30, the minute hand is at 6 and the hour hand is halfway between 2 and 3. In a mirror, the minute hand remains at 6 (vertical axis), and the hour hand moves from the '2.5' position to the '9.5' position (halfway between 9 and 10), which shows 9:30.
Comparing with options:
- Option (a) 2:30 is correct.
- Option (b) 3:30 would be the mirror image of 8:30.
- Option (c) 4:30 would be the mirror image of 7:30.
- Option (d) 6:30 would be the mirror image of 5:30.

A)
2 only
B)
1 and 3 only
C)
2 and 3 only
D)
1, 2 and 3
Option B is correct: 1 and 3 only.
Who among the following is the recipient of Rokunga Award, 2024?
A)
C.Chhuanvawra
B)
C.Laizawna
C)
B.Lalthangliana
D)
C.Thangmawia
The Rokunga Award is a prestigious literary award in Mizoram, named after the legendary Mizo poet Rokunga. For the year 2024, the award was conferred upon C. Laizawna in recognition of his significant contributions to Mizo literature. The other options listed (C. Chhuanvawra, B. Lalthangliana, and C. Thangmawia) are not the recipients of the 2024 award.
Choose that set of numbers from the four alternatives sets that is similar to the given set. (6:12:18)
A)
(4:8:14)
B)
(12:24:36)
C)
(6:20:26)
D)
(0:36:45)
Step 1: Analyze the relationship between the numbers in the given set (6:12:18).
- The first number is 6.
- The second number is 12, which is 6 * 2 (or 6 + 6).
- The third number is 18, which is 6 * 3 (or 12 + 6).
- The pattern is an arithmetic progression with a common difference of 6, or a ratio of 1:2:3.
Step 2: Evaluate the options based on this pattern (1:2:3 ratio).
- Option a (4:8:14): 4 * 1 = 4; 4 * 2 = 8; 4 * 3 = 12. Since the third number is 14, not 12, this is incorrect.
- Option b (12:24:36): 12 * 1 = 12; 12 * 2 = 24; 12 * 3 = 36. This perfectly matches the 1:2:3 ratio (and is an arithmetic progression with a common difference of 12). This is correct.
- Option c (6:20:26): 6 * 1 = 6; 6 * 2 = 12. Since the second number is 20, this is incorrect.
- Option d (0:36:45): 0 * 1 = 0; 0 * 2 = 0. This does not follow the ratio or a consistent additive pattern relative to the first term. This is incorrect.
Conclusion: Option b follows the same mathematical logic as the given set.
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 administration of the Lushai Hills (now Mizoram) was historically managed by British officers. However, as part of the process of Indianization of the civil services and the transition toward independence, Indian officers began to take over administrative roles. S.N. Barkataki was the first Indian to be appointed as the Superintendent of the Lushai Hills. The Superintendent was the chief administrative head of the district during the colonial and transitional period before the region evolved into a Union Territory and eventually a state. 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.
In ‘hnuaipui’ sacrifice,
A)
a full grown female pig was killed
B)
a young pig was killed
C)
mithun was killed
D)
a full grown hen was killed
In traditional Mizo culture and ancestral belief systems, 'Hnuaipui' refers to a specific type of sacrifice or ritual offering. According to Mizo customary practices and ethnographic records regarding traditional rituals, the 'hnuaipui' sacrifice specifically required the slaughter of a full-grown female pig. This ritual was often associated with seeking protection, healing, or appeasing spirits to ensure the well-being of the community or an individual. Options b, c, and d are incorrect because while mithuns (c) were used in higher-status feasts (Kut or feasts of merit) and hens (d) were used in smaller rituals, the specific requirement for 'hnuaipui' was a mature female pig.
The famous East- West War called ‘Chhak leh Thlang Indo’ was fought between -
A)
Vanhnuailiana vs Thawmvunga
B)
Lallianvunga vs Lalpuithanga
C)
Vutaand Manga vs Lalsavunga
D)
Rolura vs Vuta
The 'Chhak leh Thlang Indo' (East-West War) is a significant conflict in Mizo history. It was a power struggle for supremacy among the Mizo chiefs. The war was fought between the forces of Vanhnuailiana (representing the 'West' or Thlang) and Thawmvunga (representing the 'East' or Chhak). This conflict highlighted the fragmented nature of the Mizo chiefdoms before the British annexation. Options b, c, and d list other Mizo chiefs or combinations that were not the primary combatants of this specific historical event.
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 magical objects or 'magic bags/pouches' that possess supernatural powers. These are central to the story of 'Rairahtea', a character known for his wit and the use of magical items to outsmart others or overcome obstacles.
- Option (a) Rairahtea thawnthu: Correct. The plot revolves around the acquisition and use of these magical objects.
- Option (b) Chhura leh Naa thawnthu: This is a fable involving a clever man (Chhura) and a tiger (Naa), focusing on wit and trickery rather than magical objects like Bahhnukte.
- Option (c) Nuchhimi thawnthu: This is a tragic folk tale about a girl and her devotion/suffering, not centered on magical pouches.
- Option (d) Sichangneii thawnthu: This is another traditional tale, but it does not feature the 'Bahhnukte' as a primary plot device.
The most abundant Greenhouse Gas in the atmosphere is -
A)
Methane
B)
Carbon Dioxide
C)
Water Vapour
D)
Nitrous Oxide
To determine the most abundant greenhouse gas (GHG), we must distinguish between 'natural' abundance and 'anthropogenic' (human-caused) contribution.
1. **Water Vapour (H2O):** This is the most abundant greenhouse gas in the Earth's atmosphere. It acts as a powerful feedback mechanism; as the atmosphere warms, it holds more water vapour, which in turn traps more heat. Its concentration varies significantly by location and temperature, but globally, it contributes the most to the natural greenhouse effect.
2. **Carbon Dioxide (CO2):** While CO2 is the most significant anthropogenic (human-driven) greenhouse gas and is often the primary focus of climate change discussions due to its long atmospheric lifetime, it is less abundant than water vapour.
3. **Methane (CH4) and Nitrous Oxide (N2O):** These gases are much more potent per molecule than CO2 or H2O in terms of Global Warming Potential (GWP), but they exist in much smaller concentrations (parts per billion or low parts per million).
Therefore, in terms of sheer volume and abundance in the atmosphere, water vapour is the correct answer.
The next number in the sequence will be? 1, 3, 9, 15, 25, 35, 49, ....
A)
61
B)
63
C)
65
D)
81
To find the next number in the sequence 1, 3, 9, 15, 25, 35, 49, ..., we analyze the pattern of the numbers. The sequence is composed of two alternating patterns based on the position of the term:
1. Odd-positioned terms (1st, 3rd, 5th, 7th): 1, 9, 25, 49. These are the squares of consecutive odd numbers: 1², 3², 5², 7².
2. Even-positioned terms (2nd, 4th, 6th): 3, 15, 35. These follow the pattern (n² - 1) where n is an even number: 2²-1=3, 4²-1=15, 6²-1=35.
The next number in the sequence is the 8th term (an even position). Following the pattern for even-positioned terms, the next even number after 6 is 8. Therefore, the calculation is: 8² - 1 = 64 - 1 = 63.
Verification of options:
- a. 61: Incorrect.
- b. 63: Correct (8² - 1).
- c. 65: Incorrect.
- d. 81: This would be the 9th term (9²), not the 8th.
The series of supercomputers designed and assembled by the Centre for Development of Advanced Computing (C-DAC) in Pune, India is -
A)
PARAM
B)
Arka
C)
Arunika
D)
Mihir
The Centre for Development of Advanced Computing (C-DAC), headquartered in Pune, was established in 1988 with the primary objective of designing and developing supercomputers for India. The resulting series of supercomputers is named 'PARAM' (which stands for 'Parallel'). The first supercomputer in this series, PARAM 8000, was launched in 1991. Since then, C-DAC has developed numerous iterations and advanced versions such as PARAM Brahma, PARAM Yuva, and PARAM Siddhi. Options b, c, and d (Arka, Arunika, Mihir) are not recognized series of supercomputers developed by C-DAC.
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 air quality status to the public. It categorizes air quality into six distinct levels based on the concentration of pollutants (PM2.5, PM10, NO2, SO2, CO, and O3). The six categories are: 1. Good (0-50), 2. Satisfactory (51-100), 3. Moderate (101-200), 4. Poor (201-300), 5. Very Poor (301-400), and 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 used in the index.
- Option (d) 'Highly polluted' is not a terminology used in the official National AQI classification. While 'Poor' and 'Very Poor' exist, 'Highly polluted' is not a specific category label.
The first recipient of the Padma Shri Award among the women from Mizoram was -
A)
Khawlhkungi
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. While other women from the state have received prestigious awards for literature, arts, or social service in later years, Nuchhungi Renthlei holds the distinction of being the first female recipient of this specific civilian honor from the state.
It is a network 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 general category of network that covers a large geographical area. While the internet is the largest 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). It does not specifically refer to the mechanism of using public networks to access private ones.
Choose the odd one out from the numbers given
A)
523
B)
121
C)
324
D)
729
To find the odd one out, we examine the mathematical properties of each number provided in the options:
1. **121**: This is a perfect square ($11^2 = 121$).
2. **324**: This is a perfect square ($18^2 = 324$).
3. **729**: This is both a perfect square ($27^2 = 729$) and a perfect cube ($9^3 = 729$).
4. **523**: This number is not a perfect square or a perfect cube. In fact, 523 is a prime number.
Since options b, c, and d are all perfect squares, while option a is not, 523 is the odd one out.
Find the word which holds the same relation with the third word as there in between the first two words. Oxygen : Burn :: Carbon dioxide : ?
A)
Isolate
B)
Foam
C)
Extinguishes
D)
Explode
This is an analogy question based on the chemical properties of gases.
1. **Analyze the first pair:** Oxygen : Burn. Oxygen is a gas that supports combustion; it is necessary for a fire to burn. Therefore, the relationship is [Gas] : [Effect/Action it supports].
2. **Analyze the second pair:** Carbon dioxide : ?. Carbon dioxide is a gas that does not support combustion and is commonly used in fire extinguishers to displace oxygen and put out fires. Therefore, the relationship must be [Gas] : [Effect/Action it causes].
3. **Evaluate Options:**
- (a) Isolate: Not a chemical property of CO2 in relation to fire.
- (b) Foam: While some extinguishers use foam, CO2 itself is a gas, not foam.
- (c) Extinguishes: This is the direct opposite of 'burn'. Since Oxygen supports burning, Carbon dioxide extinguishes it.
- (d) Explode: Carbon dioxide is stable and does not cause explosions; it is actually used to prevent them in some contexts.
Thus, the correct word to complete the analogy is 'Extinguishes'.
The new snake species discovered in Mizoram in 2024 by researchers at the Mizoram University is-
A)
Sinomicrurus gorei
B)
Ahaetulla prasine
C)
Python bivittatus
D)
Smithophis mizoramensis
In 2024, researchers from Mizoram University discovered and described a new species of snake endemic to the state of Mizoram. The species was named 'Smithophis mizoramensis'. This discovery is significant as it adds to the biodiversity records of the Indo-Burma hotspot.
Analysis of other options:
- Sinomicrurus gorei: This is a species of coral snake found in other regions, not the new 2024 discovery from Mizoram University.
- Ahaetulla prasina: This is the common Green Vine Snake, widely distributed across Asia.
- Python bivittatus: This is the Burmese Python, a well-known large snake species found across Southeast Asia.
Therefore, option (d) is the only correct answer based on recent herpetological research conducted by Mizoram University.
The State Flower of Mizoram is -
A)
Rhynchostylis Retusa
B)
Red Vanda
C)
Aerides Odorata
D)
Lilium Mackliniae
The State Flower of Mizoram is the Red Vanda (Vanda scented). It is a species of orchid known for its vibrant red color and fragrance, reflecting the rich biodiversity of the state's hilly terrain.
Analysis of other options:
- Rhynchostylis Retusa: This is the state flower of some other regions/species but not Mizoram.
- Aerides Odorata: While common in Southeast Asia, it is not the official state flower of Mizoram.
- Lilium Mackliniae: This is a species of lily found in the Himalayas, but it is not the state flower of Mizoram.
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 foster the growth of science and technology in India, emphasizing the need for scientific manpower, the establishment of research institutions, and the application of science to solve national problems. It laid the foundation for India's organized scientific infrastructure.
Analysis of other options:
- 1949: This period was focused on the immediate post-independence reorganization of scientific bodies (like the CSIR), but no formal 'Scientific Policy Resolution' was adopted then.
- 1963: While science continued to evolve, the primary policy framework had already been established in 1958.
- 1971: This is far too late for the 'first' resolution; by this time, India had already achieved significant milestones like the launch of its first satellite (1975) and the development of nuclear capabilities.
In which of the following year was Mizo District Council inaugurated?
A)
25 February, 1951
B)
25 April, 1952
C)
25 May, 1953
D)
25 April, 1954
The Mizo District Council (MDC) was inaugurated on April 25, 1952. This was a significant administrative milestone in Mizo history, established under the Sixth Schedule of the Constitution of India to provide a degree of autonomy to the tribal areas for the management of their own land, forests, and local customs. Option (a), (c), and (d) are incorrect as they list different dates and years that do not align with the historical record of the Council's establishment.
A girl who fell in love with serpent in Mizo folktale is -
A)
Kungawrhi
B)
Tumchhingi
C)
Negaiteii
D)
Chawngchilhi
In Mizo folklore, Kungawrhi is the central figure of one of the most famous legends. The story tells of a beautiful girl who falls in love with a serpent (a supernatural being in the form of a snake). The serpent eventually transforms into a handsome prince. The tale is a classic example of Mizo oral tradition, focusing on themes of love, betrayal, and supernatural intervention.
Regarding the other options:
- Tumchhingi and Negaiteii are figures associated with other traditional Mizo stories or songs, often dealing with themes of longing or tragedy, but not the specific serpent-love plot.
- Chawngchilhi is a well-known figure in Mizo folklore, but her story is typically associated with different themes of beauty and tragedy rather than a romance with a serpent.
Rev. William Williams arrived Mizoram in the year -
A)
1890
B)
1891
C)
1892
D)
1893
Rev. William Williams was a pioneering missionary of the Welsh Presbyterian Mission. He arrived in Mizoram (then the Lushai Hills) in 1893. He is highly regarded in Mizo history for his contributions to education and linguistics, specifically for his work in developing the Mizo alphabet and translating religious texts. While the mission efforts began slightly earlier with others, Rev. Williams' arrival in 1893 marks a significant milestone in the establishment of the church and formal education in the region. Options a, b, and c are incorrect as they precede his arrival date.
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' (songs associated with the Puma/leopard or specific hunting/warrior contexts) were historically replaced or evolved into 'Nilen zai'. Nilen zai refers to a style of singing that became more prevalent as the social structure and cultural expressions of the Mizo people shifted. Tlanglam zai, Chawngchen zai, and Dawn zai are other forms of Mizo folk songs, but they serve different purposes: Chawngchen zai is specifically associated with the Chawngchen festival (celebrating victory in war), and Tlanglam zai is generally associated with hillside or nature-themed songs. Therefore, based on Mizo cultural heritage records, Nilen zai is the correct replacement for Puma Zai.
It is a method based on X-rays to create detailed images of the inside of the body -
A)
EEG
B)
ECG
C)
CT Scan
D)
MRI
Step-by-step reasoning:
1. The question asks for a medical imaging method that specifically uses X-rays to create detailed images of the inside of the body.
2. Analysis of options:
- EEG (Electroencephalogram): Measures electrical activity in the brain using electrodes placed on the scalp. It does not use X-rays.
- ECG (Electrocardiogram): Measures the electrical activity of the heart. It does not use X-rays.
- CT Scan (Computed Tomography): This technique uses a rotating X-ray machine and a computer to create cross-sectional 'slices' or detailed 3D images of the body's internal structures. It is fundamentally based on X-ray technology.
- MRI (Magnetic Resonance Imaging): Uses strong magnetic fields and radio waves to generate images. It does not use X-rays (and is often preferred when avoiding ionizing radiation).
3. Conclusion: Only the CT Scan fits the description of being based on X-rays to create detailed internal images.
