Question 1 of 7
1. Question
Q1. {Agri – Crops} Consider the following statements about Foot Rot disease:
- Foot Rot or Bakane disease primarily affects maize crops during the seedling stage, but can also cause infection after transplantation if infected seedlings are transplanted.
- Treatment methods for Foot Rot disease include using fungicides on seeds before sowing, as well as applying biological agents like Trichoderma harzianum to seedlings before sowing and transplantation.
Which of the above statement(s) is/are correct?
Correct
Explanation
Statement 1 is incorrect
- Foot Rot or Bakane disease is a fungal disease that predominantly affects Basmati rice crops, particularly during the seedling stage.
- However, it can also lead to infection after transplantation if infected seedlings are transplanted, posing a risk to the rice crop at various growth stages.
Statement 2 is correct
- The current approach to managing Foot Rot or Bakane disease involves pre-sowing and pre-transplantation treatment of seedlings with Trichoderma harzianum, a beneficial fungus known for its antagonistic properties against plant pathogens.
- Additionally, seeds are treated with fungicides like Sprint 75 WS to mitigate the risk of fungal infection.
- However, it is noted that while these treatments are effective in controlling the disease, they can have negative implications for soil health and may pose risks to consumers due to potential toxicity residues in the rice.
Answer: (b) 2 only; Difficulty Level: Medium

Question 2 of 7
2. Question
Q2. {Envi – Air Pollution} Consider the following statements about Nitrogen Dioxide (NO2):
- Industrial activities are identified as the principal outdoor source of Nitrogen Dioxide (NO2).
- Nitrogen Dioxide (NO2) contributes to enhanced greenhouse effect and global warming.
Which of the above statement(s) is/are correct?
Correct
Explanation
Statement 1 is incorrect
- NO2 and other nitrogen oxides in the outdoor air contribute to particle pollution and to the chemical reactions that make ozone.
- Road traffic is the principal outdoor source of nitrogen dioxide.
- Nitrogen dioxide causes a range of harmful effects on the lungs, including:
- Increased inflammation of the airways.
- Worsened cough and wheezing.
- Reduced lung function.
- Increased asthma attacks.
Statement 2 is incorrect
- Nitrogen Dioxide (NO2) primarily contributes to air pollution and the formation of photochemical smog rather than directly causing the enhanced greenhouse effect and global warming.
- While NO2 is a greenhouse gas, its contribution to global warming is relatively minor compared to other greenhouse gases such as carbon dioxide (CO2) and methane (CH4).
- Nitrous oxide (N2O) enhances the greenhouse effect just as carbon dioxide does by capturing reradiated infrared radiation from the Earth’s surface and subsequently warming the troposphere.
Answer: (d) Neither 1 nor 2; Difficulty Level: Medium

Question 3 of 7
3. Question
Q3. {IE – Banking} Consider the following statements about Lookout Circulars (LOCs):
- The Enforcement Directorate (ED) of the Department of Revenue, Ministry of Finance issues lookout circulars (LOCs) against loan defaulters.
- A LOC can be issued against a borrower/defaulter of Private as well as Public Sector Banks.
Which of the above statement(s) is/are not correct?
Correct
Explanation
Statement 1 is incorrect
- The Bureau of Immigration of the Ministry of Home Affairs (MHA) issues lookout circulars (LOCs).
- These LOCs allowed authorities at any departure port to prevent PSB debtors from leaving India.
- Default borrowers include not only the borrowers but also the guarantors for repayment of loans and the principal officers or directors of corporate entities in debt.
Statement 2 is incorrect
- The ruling quashed the centre’s Office Memoranda (OM) that empowered PSBs to issue LOCs.
- The court described these LOCs as “strong-arm tactics” to bypass legal processes. Such tactics violate fundamental rights guaranteed under Articles 14 and 21 of the IC.
- The fundamental right to travel abroad cannot be restricted by executive action without a legal basis.
- Allowing banks to act as judges and executioners violates Article 21 of the IC.
- The government failed to prove that debt had been recovered through the denial of travel permission.
- The court deemed the inclusion of only PSBs (not Private banks) in the LOC issuance to violate Article 14 of the IC and be arbitrary. It disagreed with the distinction between borrowers from PSBs and those from private banks.

Question 4 of 7
4. Question
Q4. {Prelims – Envi – Species} Consider the following statements about sperm Whales:
- Sperm whales are mostly white in color and use a strange whistling sound to communicate with each other.
- Sperm whales have a waxy substance called spermaceti in their tails.
- Sperm whales have a small brain relative to other whale species.
- Sperm whales are listed as Vulnerable Species under IUCN red List.
How many of the above statement(s) is/are correct?
Correct
Explanation
Statement 1 is incorrect
- Sperm Whales are mostly dark grey, with some having white patches on their belly.
- Some sperm whales turn white as they age.
- They are found in all deep oceans, from the equator to the edge of the pack ice in the Arctic and Antarctic.
-
Scientists studying sperm whales have discovered that they communicate through a sort of “phonetic alphabet”, enabling them to build a rough equivalent of what humans refer to as words and phrases.
-
The study, published on Tuesday, involved sperm whales living around the Caribbean island of Dominica, describing how they communicate by squeezing air through their respiratory systems to make rapid clicks resembling Morse code, with sets of the noises making up the basic building blocks of language.
Statement 2 is incorrect
- Sperm whales, or cachalots, are the largest-toothed whales.
- They are named after the waxy substance spermaceti, which is not found in their tails; it is an oil sac found in their heads.
Statement 3 is incorrect
- Sperm whales have the largest brain of any animal on Earth, more than five times heavier than the human brain.
- Therefore, they have a large brain relative to other whale species.
Statement 4 is correct

Question 7 of 7
7. Question
Q7. {Prelims – PIN World} Batagaika Crater, recently seen in news is located in which of the following country?
Correct
Explanation
- The Batagaika Crater, located in the Siberian taiga of Russia, is a natural geological phenomenon characterized by its large depression in the ground.
- This depression is often referred to as a “megaslump” due to its significant size and depth. The formation of the Batagaika Crater can be attributed to the collapse of a permafrost dome.
- Permafrost is a layer of soil or rock that remains frozen throughout the year, occurring in regions where the ground temperature remains below freezing point for extended periods.
- In the case of Batagaika Crater, the permafrost dome likely formed over thousands of years as layers of soil and ice accumulated and froze.
- However, various factors can trigger the destabilization of the permafrost, leading to its collapse and the formation of a crater-like depression. These factors may include changes in temperature, thawing of the permafrost due to climate change, as well as human activities such as deforestation or mining.
- As the permafrost dome collapses, it creates a large depression in the ground, revealing layers of sediment and exposing previously frozen soil and organic matter. The unique appearance of the Batagaika Crater, with its steep slopes and exposed layers, has led to its nickname as the “gateway to the underworld.”
- The exposed layers of sediment within the crater provide valuable insights into past environmental conditions and geological history.
- Scientists study these layers to understand climate change, permafrost dynamics, and landscape evolution over time.
