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.
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.
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.
Find the odd one out
A)
1
B)
2
C)
3
D)
4
Among the given numbers, '1' (option a) is the odd one out because it is neither a prime number nor a composite number. In contrast, the other numbers can be classified under these categories: 2 and 3 are prime numbers, while 4 is a composite number. Additionally, 1 has only one factor (itself), whereas all other options have two or more factors.
In a sequence of shapes, if a square becomes a triangle, and a pentagon becomes a square, what would a circle most likely become in a logic of decreasing side counts?
A)
A straight line
B)
A dot
C)
An oval
D)
A Semi-circle
1. **Pattern Identification**: The sequence demonstrates a pattern of decreasing the number of sides of a geometric shape by 1 at each step (Pentagon with 5 sides becomes a Square with 4 sides; a Square with 4 sides becomes a Triangle with 3 sides).
2. **Applying the Pattern**: A circle is geometrically considered to have 1 continuous curved side (or boundary). Following the logic of decreasing the side count by 1, a shape with 1 side (circle) would become a shape with 0 sides, which is represented by a dot (or a point).
3. **Why other options are incorrect**:
- **A straight line** (Option a) represents a 1-dimensional figure with 1 side, which does not reduce the side count from a circle (1 side).
- **An oval** (Option c) is topologically equivalent to a circle and still has 1 boundary, representing no decrease.
- **A Semi-circle** (Option d) consists of two boundaries (one curved and one straight line), which actually increases the complexity/side count compared to a circle.
The curved surface area of a cylinder is thrice the area of its base. If r is the radius of the base and h is its height, then r : h is equal to
A)
2 : 5
B)
3 : 5
C)
3 : 2
D)
2 : 3
To find the ratio $r : h$, we use the formulas for the curved surface area (CSA) and the base area of a cylinder:
1. Curved Surface Area (CSA) = $2\pi rh$
2. Base Area = $\pi r^2$
According to the problem, the CSA is thrice the base area:
$2\pi rh = 3\pi r^2$
Dividing both sides by $\pi r$ (since $r \neq 0$):
$2h = 3r$
Rearranging the terms to find the ratio $r : h$ (or $\frac{r}{h}$):
$\frac{r}{h} = \frac{2}{3}$
Thus, $r : h = 2 : 3$.
- **Option d** is correct because it correctly represents the ratio $r : h = 2 : 3$.
- **Option c (3 : 2)** is incorrect as it represents the ratio of height to radius ($h : r$) instead of radius to height ($r : h$).
- **Options a (2 : 5) and b (3 : 5)** are incorrect because they do not satisfy the relation $2h = 3r$ derived from the given geometric conditions.
Which of the following is not a type of mushroom?
A)
Pauithin
B)
Changting
C)
Changvar
D)
Pangkhau
In the Mizo language, mushrooms are locally referred to as 'Pa'.
1. **Pangkhau** (often spelled 'phangkhau') is not a mushroom; it refers to a grasshopper or insect in Mizo.
2. **Pauithin** (Pa-ui-thin), **Changting** (Pa-changting), and **Changvar** (Pa-changvar) are all well-known varieties of wild edible/non-edible mushrooms found in the forests of Mizoram.
Mizoram was declared as a ‘disturbed area’ under the Assam Disturbed Areas Act 1955 in:
A)
1966
B)
1967
C)
1968
D)
1969
Mizoram (then the Mizo Hills district of Assam) was declared a 'disturbed area' under the Assam Disturbed Areas Act, 1955, in March 1966. This declaration was made immediately following the outbreak of the armed uprising by the Mizo National Front (MNF) on March 1, 1966, to facilitate the deployment of the military and restore order. The other options (1967, 1968, and 1969) are incorrect as they represent years after the initial declaration and the deployment of armed forces had already taken place.
Which of the following is NOT a feature of India’s startup ecosystem?
A)
High service-sector dominance
B)
Public digital platforms
C)
Strong deep-tech commercialization
D)
Government incubation support
Option 'c' is correct because strong deep-tech commercialization is NOT a prominent feature of India's startup ecosystem. While deep-tech startups are growing, they still face significant challenges in India, such as high capital requirements, long gestation periods, and a lack of mature funding and IP commercialization infrastructure. In contrast, the other options are well-established features: (a) India's startup ecosystem is heavily dominated by the service sector (SaaS, fintech, e-commerce); (b) Public digital platforms like UPI, Aadhaar, and ONDC act as major enablers; and (d) Government incubation support is highly active through initiatives like Startup India and the Atal Innovation Mission.
Who introduced the practice of burying a deceased person at thlanmual?
A)
Zosaphluia
B)
Zosapthara
C)
Pu Buanga
D)
C.G.G. Helm
The practice of burying the deceased in a common village cemetery (thlanmual), rather than the traditional custom of burying them within the house courtyard or under the floor, was introduced in Mizoram by the Welsh Christian missionary Rev. D.E. Jones, popularly known to the Mizos as Zosaphluia. He arrived in Mizoram in 1897 and initiated several social and religious reforms. Among the other options: Zosapthara (Edwin Rowlands) is primarily remembered for his contributions to education and music; Pu Buanga (J.H. Lorrain) is famous for creating the Mizo script and dictionary; and C.G.G. Helm was a British administrator, not the missionary responsible for this reform.
Who was awarded the ‘Kaisar-i-Hind’ medal by the British government among Mizo Chiefs?
A)
Chief Rothangpuia
B)
Chief Lalluauva
C)
Chief Khamliana
D)
Chief Darmaka
Chief Khamliana of Lungleng was a prominent Mizo chief who was awarded the 'Kaisar-i-Hind' medal by the British government in recognition of his outstanding services, cooperation with the British administration, and his role in promoting education (he was among the first Mizos to learn to write using the Roman script). The other options—Chief Rothangpuia, Chief Lalluauva, and Chief Darmaka—were also notable Mizo chiefs of their time, but none of them were decorated with the Kaisar-i-Hind medal.
Which number will come next in the given series? 2, 8, 18, 32, 50, …
A)
78
B)
68
C)
72
D)
70
The given series is 2, 8, 18, 32, 50, ...
There are two simple ways to find the pattern:
**Method 1: Using the formula $2n^2$**
- 1st term: $2 \times 1^2 = 2$
- 2nd term: $2 \times 2^2 = 8$
- 3rd term: $2 \times 3^2 = 18$
- 4th term: $2 \times 4^2 = 32$
- 5th term: $2 \times 5^2 = 50$
- 6th term (next term): $2 \times 6^2 = 2 \times 36 = 72$
**Method 2: Difference between consecutive terms**
- $8 - 2 = 6$
- $18 - 8 = 10$
- $32 - 18 = 14$
- $50 - 32 = 18$
The differences are 6, 10, 14, 18, which increase by 4 each time. The next difference must be $18 + 4 = 22$.
Therefore, the next term is $50 + 22 = 72$.
Options a (78), b (68), and d (70) are incorrect because they do not follow this mathematical progression.
Light Emitting Diodes (LEDs) are generally more energy-efficient compared to incandescent bulbs due to which of the following reasons?
A)
They produce less heat and convert electricity to light more effectively.
B)
They absorb more heat.
C)
They are made of metallic materials.
D)
They use alternating current (AC).
Option 'a' is correct because LEDs (Light Emitting Diodes) work on the principle of electroluminescence, converting electrical energy directly into light with minimal heat loss. In contrast, incandescent bulbs rely on heating a filament, wasting about 90% of their energy as heat. Option 'b' is incorrect because absorbing heat does not improve lighting efficiency. Option 'c' is incorrect because LEDs are made of semiconductor materials (like gallium arsenide), not metals. Option 'd' is incorrect because LEDs natively operate on Direct Current (DC), not Alternating Current (AC), requiring a driver to convert household AC to DC.
Name the composer of the song ‘He lei hi chatuan ram a tling lo’.
A)
Patea
B)
Saihnuna
C)
Damhauhva
D)
R.L. Kamlala
The song 'He lei hi chatuan ram a tling lo' was composed by Damhauhva, who is one of the most prominent and respected composers in Mizo gospel music history. The other options are incorrect because: Patea (Option a) is famous for songs like 'Ka va ngai em'; Saihnuna (Option b) is known for classics like 'Khawvel hi thlaler a lo ni'; and R.L. Kamlala (Option d) is renowned for hymns such as 'Ka hmun nuam bik'.
In 1986, she was crowned as the first ‘Miss Mizo’:
A)
Brigitte Zohmingi
B)
Lalbiakzuali
C)
Zohlupuii
D)
Luzy Zorinpuii
Lalbiakzuali was crowned as the first 'Miss Mizo' in the inaugural Miss Mizo beauty pageant held in 1986. The other options (Brigitte Zohmingi, Zohlupuii, and Luzy Zorinpuii) are incorrect because they did not win the title in the debut year of 1986.
Which village in Lushai Hills was known as Kristian khua or Pathian thuawih khua at the beginning of the spread of Christianity in Mizoram?
A)
Durtlang
B)
Sethlun
C)
Pukpui
D)
Chaltlang
Sethlun village, located near Lunglei in the southern part of Mizoram (Lushai Hills), was historically known as 'Kristian khua' (Christian village) or 'Pathian thuawih khua' (God-obeying village) during the early spread of Christianity. This was because it became one of the earliest villages where a significant portion of the population embraced the Christian faith and lived according to Christian principles. In contrast, Durtlang is famous for the establishment of the first Christian mission hospital, Pukpui is associated with sectarian movements like the Lalpa Kohhran Pawl, and Chaltlang is a prominent locality in Aizawl with no such historical designation.
The Lushai Hills District was declared as ‘Excluded Area’ under:
A)
The Government of India Act 1909
B)
The Government of India Act 1919
C)
The Government of India Act 1935
D)
The Government of India Act 1948
The Lushai Hills District (present-day Mizoram) was declared an 'Excluded Area' under the Government of India Act 1935. Under this Act, the administration of 'Excluded Areas' was placed directly under the discretionary powers of the Governor of Assam, meaning the provincial legislature had no jurisdiction over them.
- Why other options are incorrect:
- Option a (The Government of India Act 1909) did not contain provisions for classifying regions as 'Excluded Areas'.
- Option b (The Government of India Act 1919) classified these hill tracts as 'Backward Tracts' rather than 'Excluded Areas'.
- Option d (The Government of India Act 1948) is incorrect as there was no such Act passed in 1948; the Indian Independence Act was passed in 1947.
The Superintendent of Lushai Hills who officially abolished the traditional Zawlbuk during the colonial rule in Mizoram was:
A)
SN Mackenzie
B)
NE Parry
C)
CGG Helme
D)
AG McCall
In 1938, C.G.G. Helme, the Superintendent of Lushai Hills, officially abolished the traditional Mizo bachelor's dormitory known as the 'Zawlbuk'. Although the institution had already been in decline due to the spread of formal education and Christian missionary activities, Helme's official decree marked its formal end.
- **SN Mackenzie (Option a)** served as Superintendent much earlier (1917–1920) and was not associated with the abolition.
- **NE Parry (Option b)** served as Superintendent from 1924 to 1928 and is famous for his anthropological work on the Lakher people, not the abolition of the Zawlbuk.
- **AG McCall (Option d)** served as Superintendent from 1932 to 1943 and wrote 'Lushai Chrysalis', but the specific official order of abolition in 1938 was passed by C.G.G. Helme.
The first Political Officer of the North Lushai Hills under the British government was:
A)
CS Murray
B)
Captain J Shakespear
C)
Captain HR Browne
D)
RB McCabe
Captain H.R. Browne was appointed as the first Political Officer of the North Lushai Hills on April 1, 1890, with his headquarters at Aizawl. He was unfortunately killed in an ambush by the Lushais in September 1890.
- CS Murray (Option a) was the first officer in charge of the South Lushai Hills under the Bengal government.
- Captain J. Shakespear (Option b) served as the Superintendent of the South Lushai Hills and later became the first Superintendent of the amalgamated Lushai Hills District in 1898.
- R.B. McCabe (Option d) succeeded Captain H.R. Browne as the Political Officer of the North Lushai Hills after Browne's death.
With reference to ‘Ethanol Blending’ in India, what is the target percentage of ethanol to be blended in petrol by the year 2025-26?
A)
10%
B)
50%
C)
20%
D)
100%
The Government of India, under the National Policy on Biofuels, originally set a target of achieving 20% ethanol blending in petrol (E20) by 2030. However, this target was subsequently advanced by five years to the biofuel year 2025-26. Option 'a' (10%) is incorrect because India already achieved the 10% blending target in June 2022. Options 'b' (50%) and 'd' (100%) are incorrect as there are no such targets set for the year 2025-26 due to vehicle engine compatibility and ethanol production capacity limits.
The first genetically modified crop approved for commercial cultivation in India was_________ .
A)
Bt-brinjal
B)
GM Mustard
C)
Bt-Mustard
D)
Bt-cotton
Bt-cotton is the correct answer. It was approved for commercial cultivation in India in 2002 by the Genetic Engineering Appraisal Committee (GEAC), making it the first and currently the only genetically modified (GM) crop officially grown by farmers in India. Bt-brinjal (option a) was cleared by GEAC in 2009 but was placed under an indefinite moratorium in 2010 due to safety concerns. GM Mustard / Bt-Mustard (options b and c) received recommendation for environmental release in 2022 but has not yet been fully cleared for commercial cultivation due to ongoing legal challenges.
The phrase Hrum sawm is used for addressing:
A)
Hmeichhia
B)
Hmar
C)
Lal
D)
Pawi
In Mizo culture and traditional literature, the phrase 'Hrum sawm' (or 'Hrum-sawm') is a historical term of address used specifically for the Hmar people. Therefore, option 'b' is correct. The other options are incorrect because 'Hmeichhia' means woman/female, 'Lal' refers to a chief or ruler, and 'Pawi' refers to the Lai/Pawi community, none of whom are addressed by this specific phrase.
In Mizo poetry, Thlang khuandim means:
A)
To marry a husband at another village
B)
To marry a husband at the same village
C)
To marry a wife
D)
To marry a wife from another village
In Mizo poetry and traditional literature, the term 'Thlang khuandim' (or simply 'Khuandim') is a poetic expression that means 'to marry a wife' or 'to take a wife'. Therefore, option (c) is the correct answer. Options (a) and (b) are incorrect because they refer to marrying a husband, whereas 'khuandim' specifically pertains to a man marrying a wife. Option (d) is incorrect because the term does not inherently specify that the wife must be from another village.
Who was the first to receive Capital Punishment inside Mizoram?
A)
Lamsuaka
B)
Lianphunga
C)
Khamliana
D)
Chawia
Lamsuaka was the first person to receive capital punishment (by hanging) inside Mizoram, executed at the Aizawl Jail during the British administration. The other options are incorrect: Lianphunga was a prominent Mizo chief known for his resistance and raids against the British but was not the first to be executed inside Mizoram; Khamliana was a famous Mizo chief recognized as one of the first literate chiefs who helped in recording the Mizo language; and Chawia was also a historical figure/chief but not the first recipient of capital punishment.
Find the wrong number in the given series: 10, 41, 94, 1624, 2516, 3625
A)
94
B)
2516
C)
10
D)
1624
The terms in the series are formed by concatenating the square of the term's position ($n^2$) with the square of the preceding integer ($(n-1)^2$).
- **1st term ($n=1$):** $1^2$ and $0^2$ = 10
- **2nd term ($n=2$):** $2^2$ and $1^2$ = 41
- **3rd term ($n=3$):** $3^2$ and $2^2$ = 94
- **4th term ($n=4$):** $4^2$ and $3^2$ = 169 (but given as 1624)
- **5th term ($n=5$):** $5^2$ and $4^2$ = 2516
- **6th term ($n=6$):** $6^2$ and $5^2$ = 3625
Thus, **1624** is the wrong number in the series and should be replaced by **169**. Other options (10, 94, 2516) perfectly follow this established pattern.
