The census recorded a total population of 82,434, which consisted of 39,075 males and 43,359 females. The other options (78,856, 96,645, and 1,00,237) are incorrect as they do not correspond to the official population figures recorded during the 1901 census.
What is the main source of energy in solar flares?
A)
Gravitational energy
B)
Magnetic energy
C)
Nuclear energy
D)
Solar tidal energy
The correct option is 'b' (Magnetic energy). Solar flares are sudden, intense bursts of radiation caused by the rapid release of magnetic energy stored in the Sun's corona, primarily through a process known as magnetic reconnection.
Why other options are incorrect:
- Gravitational energy (a) is involved in stellar formation and collapse but does not power solar flares.
- Nuclear energy (c) (specifically hydrogen fusion in the Sun's core) is the source of the Sun's overall light and heat, but it is not the direct driver of localized solar flares.
- Solar tidal energy (d) is negligible and plays no role in solar flare activity.
The term ‘Technology Leapfrogging’ in the Indian context refers to:
A)
Skipping technological regulation
B)
Moving directly to advanced technologies without intermediate stages
C)
Adopting advanced technologies to bypass traditional development paths
D)
Gradual adoption of imported technologies
Technology leapfrogging refers to the phenomenon where a developing nation bypasses traditional, intermediate stages of technological development and adopts advanced technologies directly. A classic example in India is skipping the widespread installation of landline telephone infrastructure and moving directly to mobile telephony, or skipping traditional physical banking infrastructure to adopt digital payments (like UPI) directly. Option 'c' is incorrect because leapfrogging specifically refers to skipping technological stages rather than entire developmental paths. Option 'a' is incorrect as it does not mean skipping regulation, and option 'd' is incorrect because leapfrogging is rapid and non-gradual.
LIDAR is an acronym for _________ .
A)
Light Imaging and Distance Analysis for Robotics.
B)
Laser Imaging and Detection for Automatic Ranging.
C)
Light Detection and Ranging.
D)
Light Imaging and Distance Analysis for Robotics.
LIDAR is a popular remote sensing technology used to measure distance by illuminating the target with laser light and measuring the reflection with a sensor.

S.P. Mukherjee (Shanti Priya Mukherjee) was the first Lieutenant Governor of the Union Territory of Mizoram, serving from January 21, 1972, to April 23, 1974.
- Option B (S.K. Chibber) was the second Lieutenant Governor of Mizoram, serving from 1974 to 1977.
- Option A (Hiteswar Saikia) served as the Governor of Mizoram much later, from 1987 to 1989, after Mizoram attained full statehood.
- Option C (Williamson A. Sangma) was a pioneer leader from Meghalaya and served as its first Chief Minister, not as the Governor of Mizoram.
Which isotope is commonly used for dating archeological samples?
A)
Nitrogen-14
B)
Nitrogen-12
C)
Carbon-12
D)
Carbon-14
Carbon-14 (Option d) is a radioactive isotope of carbon with a half-life of approximately 5,730 years. It is commonly used in radiocarbon dating to determine the age of organic archaeological materials up to about 50,000 years old. Carbon-12 (Option c) is the stable, most abundant isotope of carbon and does not decay, making it unsuitable for dating on its own. Nitrogen-14 (Option a) is the stable product of Carbon-14 decay but is not the isotope measured for dating. Nitrogen-12 (Option b) is highly unstable with a half-life of only milliseconds, making it useless for archaeological dating.
In a row of children, Alice is sixth from the left and Zoa is fifth form the right. When they interchange their positions, Alice becomes fifteenth from the left, then what will be the position of Zoa from the right?
A)
10th
B)
12th
C)
14th
D)
16th
To find Zoa's new position from the right after they interchange positions, we can use two methods:
1. **Shift Method (Quickest):**
- Alice's position changes from 6th from the left to 15th from the left. This is an increase of 9 positions (15 - 6 = 9).
- Since they interchanged positions, Zoa's position from the right will also increase by the same number of positions.
- Zoa's new position from the right = 5 + 9 = 14th.
2. **Total Number of Children Method:**
- After interchanging, Alice is at Zoa's old position, which is 5th from the right and 15th from the left.
- Total number of children in the row = (Position from Left + Position from Right) - 1 = 15 + 5 - 1 = 19.
- Zoa is now at Alice's old position, which is 6th from the left.
- Zoa's position from the right = (Total - Position from Left) + 1 = (19 - 6) + 1 = 14th.
**Why other options are incorrect:**
- **Option a (10th):** Incorrect because it assumes a shift of only 5 positions instead of 9.
- **Option b (12th):** Incorrect because it does not account for the correct shift of 9 places.
- **Option d (16th):** Incorrect because it overestimates the shift.
Which statement best captures the institutional division of roles between MeitY, DST, and NITI Aayog regarding India’s AI ecosystem as of 2024–2025?
A)
MeitY regulates AI ethics while DST drafts the Digital Personal Data Protection Rules.
B)
MeitY leads compute infrastructure and standards; DST funds foundational research; NITI Aayog focuses on strategy and inter-ministerial coordination.
C)
NITI Aayog procures GPUs and runs national data centers; MeitY only coordinates state governments.
D)
DST leads compute infrastructure; MeitY handles basic research grants; NITI Aayog exclusively regulates AI models.
Option (b) is correct because it accurately reflects the institutional mandates of the three bodies in India's AI ecosystem:
1. **MeitY** (Ministry of Electronics and Information Technology) is the nodal ministry driving the IndiaAI Mission, which focuses on building sovereign compute infrastructure (GPU procurement), setting standards, and deploying AI applications.
2. **DST** (Department of Science and Technology) focuses on funding foundational scientific research, R&D, and establishing Technology Innovation Hubs (TIHs) under initiatives like the National Mission on Interdisciplinary Cyber-Physical Systems (NM-ICPS).
3. **NITI Aayog** acts as the premier policy think tank, responsible for drafting the National Strategy for AI ('#AIforAll') and facilitating inter-ministerial coordination and strategic roadmaps.
**Why other options are incorrect:**
* **Option (a)** is incorrect because MeitY (not DST) is the ministry responsible for drafting the Digital Personal Data Protection (DPDP) Rules.
* **Option (c)** is incorrect because GPU procurement and national data centers are managed by MeitY (via CDAC and the IndiaAI independent business division), not NITI Aayog.
* **Option (d)** is incorrect because DST does not lead the compute infrastructure (which is MeitY's domain), and NITI Aayog is a non-regulatory policy think tank and does not regulate AI models.
If ‘Rat is called Dog’, ‘Dog is called Mongoose’, ‘Mongoose is called Lion’, ‘Lion is called Snake’ and ‘Snake is called Elephant’, which animal is reared as pet?
A)
Dog
B)
Mongoose
C)
Lion
D)
Rat
To solve this coding-decoding puzzle, we first identify the real-world answer to the question: 'Which animal is reared as a pet?' In reality, a 'Dog' is reared as a pet. Next, we look at the given code translations to find what a 'Dog' is called. According to the question, 'Dog is called Mongoose'. Therefore, in this coded language, the animal reared as a pet is a 'Mongoose'. Option 'a' (Dog) is incorrect because it is the real-world name, not the coded name. Options 'c' (Lion) and 'd' (Rat) are incorrect because they represent other animals in the coding scheme.
‘Sikin Manding sap i lungmawl e, German ral lian tawnin tir suh ka lung di; Ka suihlungleng tur i dawn lo ve.’ This traditional Mizo melody is known as:
A)
Darpawngi Zai
B)
Darmani Zai
C)
Domangi Zai
D)
Hrangchhawni Zai
The correct answer is 'Darmani Zai' (Option b). This traditional Mizo melody was composed by Darmani during the First World War (around 1917) when Mizo men were recruited into the Mizo Labour Corps to serve in France. The lyrics express her grief over her lover being sent to fight the Germans ('German ral lian'). 'Sikin Manding' is a Mizo transliteration of 'Second-in-Command', referring to the British recruiting officer. Other options like 'Darpawngi Zai', 'Domangi Zai', and 'Hrangchhawni Zai' are different traditional Mizo song genres named after other composers and do not feature these specific wartime lyrics.
Which institution played a key role in India’s Green Revolution through scientific research?
A)
Indian Council of Agricultural Research (ICAR)
B)
Council of Scientific & Industrial Research (CSIR)
C)
Indian Agricultural Research Institute (IARI)
D)
National Bank for Agriculture and Rural Development (NABARD)
The Indian Council of Agricultural Research (ICAR) is the apex national body responsible for coordinating, guiding, and managing research and education in agriculture in India. It played a pivotal role in the Green Revolution during the 1960s by developing, testing, and introducing High-Yielding Variety (HYV) seeds of wheat and rice in collaboration with international agencies.
- Council of Scientific & Industrial Research (CSIR) (b) focuses on industrial and general scientific research rather than agricultural research.
- Indian Agricultural Research Institute (IARI) (c) is a premier institute that contributed significantly, but it functions under the umbrella of ICAR, which is the apex governing body.
- National Bank for Agriculture and Rural Development (NABARD) (d) is a financial institution established in 1982 to provide credit for rural development, not a scientific research body.
Whose descendant attacked the British forces garrisoned at Changsil fort and Aizawl fort during September to early October 1890?
A)
Chief Manga
B)
Chief Lianlula
C)
Chief Rolura
D)
Chief Vuttaia
In September 1890, the descendants of Chief Vuttaia (a prominent and powerful Lushai chief) launched a major armed rebellion against the British forces. They attacked the British garrisons stationed at Changsil fort and Aizawl fort, which led to intense fighting during September and early October 1890. This uprising was triggered by British high-handedness, demands for forced labor, and the imposition of taxes. Chief Manga (a), Chief Lianlula (b), and Chief Rolura (c) are incorrect because, although they were notable historical Mizo chiefs, their descendants were not the primary leaders of this specific 1890 attack on the Changsil and Aizawl garrisons.
Regarding ‘White Goods’, which sectors are covered under the PLI (Production Linked Incentive) scheme to boost domestic manufacturing?
A)
Air Conditioners and LED Lights.
B)
Automobiles and Auto Components.
C)
Solar PV Modules.
D)

Other options like Automobiles and Auto Components (Option b), Solar PV Modules (Option c), and Textiles and Apparel (Option d) are covered under separate, dedicated PLI schemes of the Government of India and do not fall under the 'White Goods' category.
Which letter is exactly midway between the seventh letter from the left and the fifteenth letter from the left?
A)
J
B)
K
C)
L
D)
I
To find the letter exactly midway between the seventh and fifteenth letters of the English alphabet, we can calculate the average of their positions:
1. The 7th letter from the left is G.
2. The 15th letter from the left is O.
3. The midway position is calculated as (7 + 15) / 2 = 22 / 2 = 11.
4. The 11th letter of the English alphabet is K, which corresponds to option 'b'.
Other options are incorrect because:
- 'J' (option a) is the 10th letter.
- 'L' (option c) is the 12th letter.
- 'I' (option d) is the 9th letter.
With reference to ‘Liquid Nano Urea’, which organization developed the world’s first commercial version of this fertilizer in India?
A)
FCI (Food Corporation of India)
B)
IFFCO (Indian Farmers Fertiliser Cooperative Limited)
C)
(NFL) National Fertilizers Limited
D)
ICAR (Indian Council of Agricultural Research)
The correct option is 'b' (IFFCO). Indian Farmers Fertiliser Cooperative Limited (IFFCO) indigenously developed the world's first Nano Urea Liquid at its Nano Biotechnology Research Centre (NBRC) in Kalol, Gujarat, and launched it commercially in 2021.
- Option 'a' (FCI) is incorrect because the Food Corporation of India is responsible for food grain procurement and distribution, not fertilizer research.
- Option 'c' (NFL) is incorrect as National Fertilizers Limited is a state-owned producer of fertilizers but was not the developer of this technology.
- Option 'd' (ICAR) is incorrect because the Indian Council of Agricultural Research is an apex body for agricultural research and education, but the commercial development of Liquid Nano Urea was specifically achieved by the cooperative IFFCO.
The commander of the initially called the 27th Lushai Labour Corps serving in France during World War I was:
A)

J Hezlett
D)
HAC Colouhoun
The 27th Lushai Labour Corps was raised in 1917 during World War I to assist the Allied war effort in France. It was commanded by Mr. J. Hezlett, ICS, who was the Superintendent of the Lushai Hills at the time.
- Option A (Lieutenant Colonel A Playfair) was a British officer associated with the administration of the Garo Hills and other regions in Assam, but did not command this corps.
- Option B (Major GH Loch) served as the Commandant of the Lushai Hills Military Police at an earlier period (late 19th and early 20th century).
- Option D (HAC Colquhoun/Colouhoun) was an ICS officer who served as the Superintendent of the Lushai Hills much earlier (around 1905–1906) and was not the commander during WWI.
Long term exposure to which of the following element can cause cancer?
A)
Iron
B)
Chlorine
C)
Iodine
D)
Arsenic
Arsenic is a highly toxic element and a well-documented Group 1 human carcinogen. Long-term exposure to arsenic, primarily through contaminated drinking water and food, is scientifically proven to cause cancers of the skin, lungs, bladder, and kidneys. In contrast, Iron (a) and Iodine (c) are essential dietary nutrients required for normal body function, and Chlorine (b) is a common disinfectant that, while toxic in high concentrations, is not classified as a primary carcinogen under normal exposure conditions.
Which material is used for protection from nuclear radiation?
A)
Gold
B)
Titanium
C)
Lead
D)
Platinum
Lead (c) is the standard material used for protection against nuclear radiation. Due to its high density and high atomic number (Z=82), lead is extremely effective at absorbing and scattering harmful ionizing radiation, such as gamma rays and X-rays. While Gold (a) and Platinum (d) are also dense, they are far too expensive and rare to be used for radiation shielding. Titanium (b) is strong and lightweight but has a much lower density and atomic number, making it ineffective for radiation protection compared to lead.
Lalvunga Zai belongs to which category?
A)
Chai hla
B)
Chawngchen zai
C)
Salu lam hla
D)
Hlado
Lalvunga Zai is a traditional Mizo folk song category that belongs to 'Chawngchen zai', which are songs sung during the Chawng festival celebrations. Other options are incorrect because: 'Chai hla' (Option a) refers to songs sung during the Chapchar Kut festival for the Chai dance; 'Salu lam hla' (Option c) refers to songs sung during the celebration of a successful hunt of a wild animal; and 'Hlado' (Option d) refers to chants or cries of victory uttered by hunters after a successful hunt.

What was the Mizo name given to Thomas Herbert Lewin (1839-1916)?
A)
Thangliana
B)
Zochhumi Pa
C)
Hmuihmula
D)
Dari Pa
Thomas Herbert Lewin (1839–1916) was a prominent British administrator in the Chittagong Hill Tracts and Lushai Hills. He was highly respected and loved by the Mizo people, who affectionately named him 'Thangliana', which means 'man of great fame' or 'greatly renowned'. The other options, such as 'Zochhumi Pa', 'Hmuihmula', and 'Dari Pa', are incorrect as they do not represent the Mizo name given to Lewin, although Lewin had close associations with a Mizo chief's daughter named Dari.
