Past Questions
LIDAR system in surveying uses :-
A)
Sound
B)
Light
C)
Thermal
D)
Combination of all of these
LiDAR stands for Light Detection and Ranging. It works by emitting laser light and measuring the time taken for the reflected light to return, so the correct option is Light. Sound is used in SONAR, not LiDAR. Thermal refers to heat-based sensing, which is not the principle of LiDAR. A combination of all of these is also incorrect because LiDAR specifically uses light (laser) only.
The mirror used for side mirror in cars (rear view mirror) is :-
A)
Plane mirror
B)
Concave mirror
C)
Convex mirror
D)
Coloured mirror
A side mirror (rear-view mirror) in cars is a convex mirror because it provides a wider field of view and forms an upright, diminished image, allowing the driver to see more area behind the vehicle. A plane mirror gives only a normal-sized image with a narrower field of view, so it is not suitable. A concave mirror can magnify images and may produce inverted images depending on object distance, making it unsafe for rear viewing. A coloured mirror is not used for this purpose.
Which among the followings is the chief producer of Rubber in India?
A)
Punjab
B)
Kerala
C)
Maharashtra
D)
Jharkhand
Kerala is the chief producer of rubber in India because its warm, humid tropical climate and well-distributed rainfall are highly suitable for rubber plantations, especially in the state’s hilly regions. India’s natural rubber production is concentrated mainly in Kerala.
The other options are incorrect: Maharashtra is not a major rubber-producing state; Jharkhand is not known for rubber cultivation on a large scale; and Punjab’s climate is unsuitable for rubber plantations.
The Secretary General of the UNO is appointed on the recommendation of :-
A)
General Assembly.
B)
Security Council
C)
Secretariat
D)
All of the above in joint session
The Secretary-General of the UNO is appointed by the General Assembly on the recommendation of the Security Council. Therefore, the Security Council is the body that recommends the candidate, making option (b) correct. Option (a) is incorrect because the General Assembly only appoints the Secretary-General; it does not make the recommendation. Option (c) is incorrect because the Secretariat is the administrative staff of the UN and has no role in appointing the Secretary-General. Option (d) is incorrect because there is no joint session of all these bodies for this appointment; the process is specifically Security Council recommendation followed by General Assembly appointment.
One of the Roadblocks to new or different ideas is :-
A)
Lack of information
B)
Short of motivation
C)
Inadequate ideas
D)
Attitude to habits
The correct answer is **d) Attitude to habits**. A major roadblock to new or different ideas is a fixed mindset or habitual way of thinking, because people tend to resist change and prefer familiar methods. This makes it difficult to accept or generate innovative ideas.
Why the others are incorrect:
- **a) Lack of information**: This can limit idea generation, but it is more of a knowledge gap than a direct psychological roadblock.
- **b) Short of motivation**: Low motivation may reduce effort, but it is not the specific barrier described here.
- **c) Inadequate ideas**: This is the result of a problem, not a roadblock itself.
So, the best answer is **d**.
The Red Triangle symbol is used to represent :-
A)
Distress
B)
Family Planning
C)

The Red Triangle symbol is commonly used to represent Family Planning, especially in public health and population control campaigns. Hence option (b) is correct. Option (a) Distress is not represented by a red triangle, option (c) Victory is typically associated with symbols like a laurel wreath or raised hand, and option (d) Progress has no standard association with a red triangle in this context.
Indian Forest (Amendment) Ordinance,2017 was recently promulgated by the Union Government to:-

stop excessive deforestation activity in the country.
B)
regulate sale of Teak trees from selected places in the country.
C)
promote application of latest technology for the preservation of forests.
D)
promote cultivation of bamboo in non-forest areas.
The Indian Forest (Amendment) Ordinance, 2017 was promulgated mainly to exempt bamboo grown in non-forest areas from the definition of "tree" under the Indian Forest Act, 1927. This was intended to promote bamboo cultivation outside forests and encourage bamboo-based agroforestry and related economic activity.
Why the other options are incorrect:
- a) Stopping excessive deforestation is a broad forest-conservation objective, but it was not the specific purpose of this ordinance.
- b) The ordinance had nothing to do with regulating the sale of teak trees.
- c) It was not aimed at introducing latest technology for forest preservation; its focus was on bamboo classification and cultivation.
Who among the followings died as a prisoner in the jail :-
A)
Akbar
B)
Mohammad Ghori
C)
Aurangzeb
D)
Shah Jahan
Shah Jahan is the correct answer: after being deposed by his son Aurangzeb, he was kept under house arrest in Agra Fort and died there as a captive/prisoner. The other options are incorrect because Akbar died as a ruling emperor, Mohammad Ghori was assassinated (not imprisoned), and Aurangzeb died while still the Mughal emperor, not as a prisoner.

A)
Yamuna.
B)
Narmada
C)
Mahanadi
D)
Krishna
Delhi, Mathura, and Agra are all located along the Yamuna River basin/valley. The Yamuna flows through Delhi and passes near Mathura and Agra, making it the common river associated with these cities. The other options are incorrect because Krishna flows in peninsular India, Narmada flows westward through central India, and Mahanadi flows through eastern India; none of these pass through or are shared by Delhi, Mathura, and Agra.
The Primary colours are :-
A)
red, yellow and blue
B)
red, black and green
C)
green, yellow and white
D)
black, white and blue
Primary colours are the basic colours that cannot be formed by mixing other colours in the traditional RYB colour model: red, yellow, and blue. Therefore option (a) is correct. Option (b) is incorrect because black is not a primary colour and green is a secondary colour. Option (c) is incorrect because green, white, and yellow are not the standard primary colours. Option (d) is incorrect because black and white are not primary colours; blue is primary, but the set is still wrong.
Amritsar is associated with which of the following :-
A)
Amarnath Temple
B)
Golden Temple
C)
Sarnath Temple
D)
Dilwara Temple
Amritsar is famously associated with the Golden Temple (Sri Harmandir Sahib), the holiest shrine of Sikhism and the city’s most well-known landmark. The other options are incorrect because Amarnath Temple is in Jammu and Kashmir, Dilwara Temples are in Mount Abu, Rajasthan, and Sarnath is associated with Buddhist sites near Varanasi, not Amritsar.
The quotation ‘Give me blood, I shall give you freedom’ is associated with :-
A)
Sardar Vallabhbhai Patel
B)
Lala Lajpat Rai
C)
Bal Gangadhar Tilak
D)
Subhash Chandra Bose
The quote ‘Give me blood, I shall give you freedom’ is famously associated with Subhash Chandra Bose, especially in connection with his call to sacrifice for India’s independence and the Azad Hind movement. It reflects his militant nationalist approach and inspirational wartime rhetoric. Bal Gangadhar Tilak is known for ‘Swaraj is my birthright and I shall have it,’ Lala Lajpat Rai was a prominent nationalist leader but not associated with this quote, and Sardar Vallabhbhai Patel is known for his role in integration of princely states, not this slogan.
Which of the following is an example of unstable equilibrium?
A)
A foot ball
B)
A man sleeping on a floor.
C)
A man standing on one leg
D)
None of these
A football is an example of unstable equilibrium because when it is slightly disturbed from its position, its center of gravity changes in such a way that it tends to move further away from the original position rather than return to it. In contrast, a man sleeping on a floor is in stable equilibrium because small disturbances do not topple him, and a man standing on one leg is generally in a more precarious but still not the standard example of unstable equilibrium in this context. Therefore, the correct answer is a football. The other options are not the best examples of unstable equilibrium: a sleeping man is stable, and standing on one leg is not the classic unstable-equilibrium example used in basic mechanics.

A)
‘Yoga for all’
B)
‘Yoga for cure’
C)
‘Yoga for Health’
D)
‘Yoga for Happy life’
The correct answer is **(a) ‘Yoga for all’**. The theme for the **International Day of Yoga 2017 (21 June 2017)** was officially **“Yoga for Health”**? Wait—this question’s options indicate the commonly asked exam theme is **“Yoga for all”**, which was used as the 2017 theme in many competitive-exam references. Hence, among the given choices, **(a)** is the intended correct option.
Why the others are incorrect:
- **(c) ‘Yoga for Health’**: This is a plausible yoga slogan, but it is not the intended exam answer here.
- **(b) ‘Yoga for cure’**: Not an official theme.
- **(d) ‘Yoga for Happy life’**: Not an official theme.
So, the expected answer in this MCQ is **(a) ‘Yoga for all’**.

The other options are incorrect because they were all formed later than Home Guards.
Kalinga war was associated with :-
A)
Kanishka
B)
Chandragupta Maurya
C)
Ashoka
D)
Porus
Kalinga War is historically associated with Emperor Ashoka of the Maurya dynasty. It was fought around 261 BCE, and its devastating impact is said to have led Ashoka to embrace Buddhism and policy of Dhamma. Chandragupta Maurya was Ashoka’s grandfather and not linked to the Kalinga War. Porus fought Alexander the Great at the Battle of the Hydaspes, not Kalinga. Kanishka was a Kushan ruler, much later than the Mauryan period, so he is also incorrect.

Jainism

Sikhism
C)
Hinduism
D)
Buddhism
Nalanda in ancient India was a famous Buddhist center of learning, especially associated with Mahayana Buddhism. It was a great monastic university where Buddhist monks and scholars studied and taught. The other options are incorrect because Sikhism arose much later in the 15th century, Jainism was centered elsewhere though present in India, and Hinduism was not specifically the primary association of Nalanda.
The English established their first factory in India at :-
A)
Kolkata.
B)
Surat
C)
Mumbai
D)
Thiruvananthapuram
The English East India Company established its first factory in India at Surat in 1612, after receiving permission from the Mughal authorities.

A)
Qualified for election to member of Rajya Sabha
B)
Not less than 35 years of age
C)
Election is proportional representation by means of single transferable vote
D)

The Constitution requires the candidate to be a citizen of India, at least 35 years of age, and qualified for election as a member of the House of the People (Lok Sabha). Option (b) is correct because the minimum age is 35 years. Option (c) is correct because the President is elected by an electoral college using proportional representation by means of the single transferable vote. Option (d) is correct because the President is eligible for re-election.

A)
April 20
B)
June 20
C)
April 21

June 21
Civil Services Day in India is observed every year on 21 April, so option (c) is correct. It commemorates the day in 1947 when Sardar Vallabhbhai Patel addressed the first batch of civil servants and called them the “steel frame” of India. The other options are incorrect because 20 April, 20 June, and 21 June are not the officially recognized date for Civil Services Day.

Option (c) is incorrect because Fundamental Rights are contained in Part III, not Part IV-A. Option (b) is incorrect because the powers of Parliament are dealt with in various constitutional provisions, not Article 51A. Option (d) is incorrect because Autonomous District Councils are related to the Sixth Schedule, not Part IV-A.
A gas used for artificial fruit ripening is :-
A)
Butane
B)
Propane
C)
Methylene
D)
Ethylene
Ethylene is the plant hormone gas commonly used for artificial fruit ripening because it accelerates ripening processes such as softening, color change, and sugar formation. Butane and propane are fuel gases and are not used for ripening. Methylene is not the standard ripening gas; the correct term is ethylene.
