In case of fire due to electric short circuit, which one of the following types of fire extinguishers is used ?

[amp_mcq option1=”Foam extinguisher” option2=”Dry chemical powder extinguisher” option3=”Pressurized water extinguisher” option4=”None of the above” correct=”option2″]

This question was previously asked in
UPSC CISF-AC-EXE – 2017
The correct answer is B) Dry chemical powder extinguisher.
Fires involving electrical equipment (often classified as Class E or Class C fires) require an extinguishing agent that is non-conductive. Water-based extinguishers (like pressurized water or foam, which is largely water) are conductive and can pose a severe electrocution risk to the user when used on electrical fires. Dry chemical powder extinguishers (like ABC powder) use fine powder that smothers the fire and also works on Class A, B, and C fires, making them suitable and common for electrical fires.
Other suitable extinguishing agents for electrical fires include Carbon Dioxide (CO₂) extinguishers and Halon or Halocarbon agents (though some are restricted due to environmental concerns). The classification of fires (A, B, C, D, K, or E) helps determine the appropriate extinguishing agent. Electrical fires are commonly referred to as Class C in the US and Class E in Europe/Australia, referring to energized electrical equipment.

232. Which of the following acts cannot be authorised to be carried out by

Which of the following acts cannot be authorised to be carried out by any police officer above the rank of a Constable through a warrant by a District Magistrate, Sub-Divisional Magistrate or a Magistrate of the first class, who upon being informed, and after such inquiry as he thinks necessary, has reasons to believe that any place is used for deposit or sale of any objectionable article, or that any such objectionable article is deposited in any place?

[amp_mcq option1=”To enter such place with such assistance as may be required” option2=”To search the place in any manner as deemed fit by the officer authorised by the warrant to carry out the search” option3=”To convey such property or article before a Magistrate” option4=”To take possession of any property or article therein found which he reasonably suspects to be stolen property” correct=”option2″]

This question was previously asked in
UPSC CISF-AC-EXE – 2017
The correct answer is B) To search the place in any manner as deemed fit by the officer authorised by the warrant to carry out the search.
Section 94(1) of CrPC authorises a specified Magistrate to issue a warrant to a police officer (above Constable) to enter and search a place suspected of containing objectionable articles. The warrant can authorise the officer to enter, search, take possession of relevant articles (stolen property, counterfeit items, forged documents, etc.), convey them to a Magistrate, and secure the place. However, the Section does not grant the officer the power to search in “any manner as deemed fit”. Searches under CrPC must be conducted according to established legal procedures, such as those outlined in Section 100 regarding conducting searches in enclosed places, which include requirements like obtaining witnesses.
Authorising a search “in any manner as deemed fit” would violate the principles of due process and could lead to arbitrary and unreasonable searches. While the officer is given the authority to search the place, the *manner* of the search must conform to the law and established procedures designed to protect the rights of individuals, even during a search under a warrant.

233. Consider the following statements : Search warrant, under Section 93 o

Consider the following statements :
Search warrant, under Section 93 of the Code of Criminal Procedure 1973, may be issued where

  • 1. the Court has reason to believe that the concerned person will not produce the document or thing as required.
  • 2. such document or thing is known to the Court to be in possession of any person.
  • 3. the Court considers that the purpose of any inquiry, trial or other proceeding under this Code will be served by a general search or inspection.

Which of the statements given above is/are correct ?

[amp_mcq option1=”1 and 2 only” option2=”3 only” option3=”1 and 3 only” option4=”1, 2 and 3″ correct=”option3″]

This question was previously asked in
UPSC CISF-AC-EXE – 2017
The correct answer is C) 1 and 3 only.
Section 93(1) of the Code of Criminal Procedure, 1973 lists the circumstances under which a search warrant may be issued. These include:
1. If the court has reason to believe that a person will not produce a document or thing required by a summons or requisition (Statement 1).
2. If such document or thing is not known to the court to be in the possession of any person (which contradicts Statement 2).
3. If the court considers that a general search or inspection is necessary for the purpose of any inquiry, trial, or other proceeding (Statement 3).
Statement 2 is incorrect because Section 93(1)(b) applies when the location of the document or thing is unknown or not known to be in the possession of any specific person, making a summons under Section 91 or 92 ineffective. The power to issue a search warrant is a significant one and is exercised when production through summons/requisition is unlikely or impossible, or when a general search is deemed necessary for the investigation/proceeding.

When a hijacked aircraft lands at an Indian airport, which among the following will be responsible for laying the inner cordon ?

[amp_mcq option1=”The nearest Army Unit” option2=”CISF at the concerned airport” option3=”The District Police” option4=”CISF will lay the inner cordon and on arrival of NSG task force it (NSG) will assume the overall command” correct=”option4″]

This question was previously asked in
UPSC CISF-AC-EXE – 2017
The correct answer is D) CISF will lay the inner cordon and on arrival of NSG task force it (NSG) will assume the overall command.
In the initial phase of a hijack crisis at an Indian airport, the Central Industrial Security Force (CISF), which is responsible for airport security, lays the inner cordon around the aircraft. When the National Security Guard (NSG) task force, the designated counter-terrorism intervention force, arrives, they take over the overall command of the operation, including the management of the inner cordon and the potential intervention.
The security response to an aircraft hijack is multi-layered and involves various agencies. CISF provides the initial security ring. State Police and potentially other forces may provide outer cordons and support. The NSG is the primary intervention force for situations like hijackings. The command structure shifts to the NSG commander upon their arrival.

235. Who among the following is not exempted from Pre-embarkation Securit

Who among the following is not exempted from Pre-embarkation Security Check at Civilian Airports (as on 01.12.2015) ?

[amp_mcq option1=”Holders of Bharat Ratna decoration” option2=”His Holiness the Dalai Lama” option3=”Chiefs of Staff holding rank of full General or equivalent” option4=”Commissioner of Bureau of Civil Aviation Security” correct=”option4″]

This question was previously asked in
UPSC CISF-AC-EXE – 2017
As of the specified date (01.12.2015), the Commissioner of the Bureau of Civil Aviation Security (BCAS) was generally not included in the list of persons exempted from pre-embarkation security checks at civilian airports, unlike the other dignitaries listed.
Exemption from security checks is typically granted to very high constitutional functionaries, specific protectees (like SPG protectees), holders of high national honours, and certain security personnel *when on duty* and identified.
The list of exempted persons is periodically updated by the Ministry of Civil Aviation based on security protocols and official status. While Bharat Ratna awardees, His Holiness the Dalai Lama (due to his status and security needs), and Chiefs of Staff (ranking as full General or equivalent) were typically on the exempted list as of 2015, the Commissioner of BCAS, despite their crucial role in aviation security, was not usually on this specific personal exemption list for the physical security check.

This question was previously asked in
UPSC CISF-AC-EXE – 2017
A passenger with a licensed revolver can carry it in their hold baggage only after declaring it to the airline at the time of check-in.
Carrying firearms or ammunition in cabin baggage is strictly prohibited. Specific security procedures must be followed for transporting licensed firearms in checked baggage.
The firearm must be unloaded, properly packed in a secure case, and declared to the airline staff. There might be fees and specific documentation requirements depending on the airline and destination. Obtaining DGCA clearance for routine passenger travel with a licensed firearm is not the standard procedure; adhering to airline and security regulations at check-in is. Handing it to the Captain is incorrect.

237. Which one of the following was not a feature of India’s foreign policy

Which one of the following was not a feature of India’s foreign policy under Nehru ?

[amp_mcq option1=”Panchsheel” option2=”Non-alignment” option3=”Promoting peace and decolonisation” option4=”Cooperation among people of the South Asian region” correct=”option4″]

This question was previously asked in
UPSC CISF-AC-EXE – 2017
While promoting cooperation was part of India’s broader foreign policy, a specific focus on ‘Cooperation among people of the South Asian region’ as a defining feature under Nehru was not as prominent as Panchsheel, Non-alignment, and advocating for peace and decolonisation. Nehru’s policy focused more on non-alignment with power blocs, anti-colonialism, and global peace initiatives. Regional cooperation specifically within South Asia gained more structured importance later.
Nehruvian foreign policy was characterized by Non-Alignment, Panchsheel (peaceful coexistence), and strong support for decolonisation and world peace.
India under Nehru played a key role in the Non-Aligned Movement (NAM) and advocated for a multipolar world order, focusing on solidarity with newly independent nations in Asia and Africa. While neighbourly relations were important, the formal emphasis on ‘South Asian regional cooperation’ emerged more significantly in the 1980s with the formation of SAARC.

Consider the following :

  • Cashew
  • Papaya
  • Red sanders

How many of the above trees are actually native to India ?

[amp_mcq option1=”Only one” option2=”Only two” option3=”All three” option4=”None” correct=”option1″]

This question was previously asked in
UPSC IAS – 2024
Out of the three trees listed, only Red Sanders is native to India.
– Cashew (*Anacardium occidentale*) is native to Brazil and was introduced to India by the Portuguese.
– Papaya (*Carica papaya*) is native to tropical America (southern Mexico and Central America) and was later spread globally.
– Red Sanders (*Pterocarpus santalinus*) is endemic to a specific geographical region in India, namely the Eastern Ghats mountain range in the southern part of the Indian peninsula.
Identifying native species is important for biodiversity conservation and understanding ecological roles. While Cashew and Papaya are now widely cultivated in India, they are not indigenous to the country’s flora. Red Sanders is valued for its rich red wood and is unfortunately listed as ‘Endangered’ by the IUCN due to overexploitation.

Consider the following :

  • Butterflies
  • Fish
  • Frogs

How many of the above have poisonous species among them ?

[amp_mcq option1=”Only one” option2=”Only two” option3=”All three” option4=”None” correct=”option3″]

This question was previously asked in
UPSC IAS – 2024
All three groups listed – Butterflies, Fish, and Frogs – contain species that are poisonous.
– Butterflies: Some butterfly species, like the Monarch butterfly, are poisonous due to toxins accumulated from their host plants (e.g., milkweed). These toxins make them unpalatable to predators.
– Fish: Many fish species are poisonous if eaten (e.g., pufferfish containing tetrodotoxin). Additionally, many fish are venomous, possessing spines or barbs that deliver toxins (e.g., stonefish, lionfish, stingrays).
– Frogs: Numerous frog species, particularly brightly colored ones in tropical regions (like poison dart frogs), secrete potent toxins through their skin as a defense mechanism. These toxins can be extremely dangerous or even lethal to predators.
The terms “poisonous” (toxic when eaten or touched) and “venomous” (delivers toxin via bite, sting, etc.) are distinct, but both fall under the umbrella of containing toxins for defense or offense. The question asks about “poisonous species,” which generally encompasses both forms of toxicity in common usage, and in this context, species with either type of toxicity are found in all three groups.

Consider the following statements :

1. Lions do not have a particular breeding season.

2. Unlike most other big cats, cheetahs do not roar.

3. Unlike male lions, male leopards do not proclaim their territory by scent marking.
Which of the statements given above are correct ?

[amp_mcq option1=”1 and 2 only” option2=”2 and 3 only” option3=”1 and 3 only” option4=”1, 2 and 3″ correct=”option1″]

This question was previously asked in
UPSC IAS – 2024
Let’s evaluate each statement:
1. Lions do not have a particular breeding season. This statement is generally correct. Lions can breed throughout the year, although the timing of births might be influenced by local conditions such as prey availability, which can lead to peak periods in some areas. However, they are capable of breeding year-round, unlike some animals with strict seasonal breeding.
2. Unlike most other big cats, cheetahs do not roar. This statement is correct. Cheetahs belong to the genus *Acinonyx*, while the roaring big cats (lion, tiger, leopard, jaguar, snow leopard) belong to the genus *Panthera*. Cheetahs vocalize with chirps, purrs, hisses, and growls but lack the anatomical structure (specifically, the hyoid bone structure) that allows true roaring.
3. Unlike male lions, male leopards do not proclaim their territory by scent marking. This statement is incorrect. Leopards, both male and female, are solitary and highly territorial. They actively scent mark their territories using urine, feces, and by rubbing scent glands against objects. Male lions also scent mark, although their territorial behaviour is linked to the pride structure. The statement’s assertion that male leopards *do not* scent mark is false.
Based on the analysis, statements 1 and 2 are correct.
– Lions can breed year-round.
– Cheetahs cannot roar; they chirp, purr, etc.
– Both male lions and male leopards use scent marking to define territory.
The ability to roar is linked to the morphology of the hyoid bone. In roaring cats (*Panthera* genus), the hyoid bone is not fully ossified, allowing for a wider range of vocalization, including roaring. Non-roaring cats, including cheetahs and domestic cats, have a fully ossified hyoid bone and purr instead of roar.
