Question 1
Which of the following statements regarding rat-hole mining is/are correct?
- It involves manually excavating coal through narrow tunnels.
- It is banned in India by the National Green Tribunal (NGT) due to environmental concerns.
- It is mainly practiced in Jharkhand and Odisha.
Select the correct answer using the code below:
a) 1 and 2 only
b) 2 and 3 only
c) 1 and 3 only
d) 1, 2, and 3
✅ Answer: a) 1 and 2 only
Explanation:
- Statement 1 is correct: Rat-hole mining is a manual coal extraction technique using small, unsafe tunnels.
- Statement 2 is correct: The NGT banned rat-hole mining in 2014 due to its hazardous effects on the environment and workers’ safety.
- Statement 3 is incorrect: Rat-hole mining is not common in Jharkhand and Odisha, but rather in Meghalaya and Assam.
Question 2
Which of the following environmental issues are caused by illegal rat-hole mining?
- Acid mine drainage
- Deforestation and land subsidence
- Increased carbon sequestration in forests
- Contamination of rivers and groundwater
Select the correct answer using the code below:
a) 1, 2, and 4 only
b) 2 and 3 only
c) 1 and 4 only
d) 1, 2, 3, and 4
✅ Answer: a) 1, 2, and 4 only
Explanation:
- Rat-hole mining leads to severe environmental degradation, including:
- Acid mine drainage (AMD), which pollutes water bodies.
- Deforestation due to unchecked mining expansion.
- Land subsidence, making areas prone to collapses.
- Contamination of groundwater with toxic chemicals.
- Statement 3 is incorrect: Rat-hole mining reduces forest cover, thereby decreasing carbon sequestration.
Topic 2: Steps on for Climate Change Mitigation in Assam
Question 3
Which of the following schemes is aimed at climate adaptation and flood control in Assam?
a) Jal Shakti Abhiyan
b) Assam Climate Action Plan (ACAP)
c) PM-KISAN
d) Atal Mission for Rejuvenation and Urban Transformation (AMRUT)
✅ Answer: b) Assam Climate Action Plan (ACAP)
Explanation:
- The Assam Climate Action Plan (ACAP) is a state initiative under the National Action Plan on Climate Change (NAPCC).
- It focuses on flood resilience, renewable energy, and afforestation to tackle climate risks in Assam.
- Jal Shakti Abhiyan deals with water conservation at a national level.
- PM-KISAN is a direct income support scheme for farmers, and AMRUT is focused on urban development.
Question 4
Which of the following factors contribute to climate change vulnerability in Assam?
- Glacial melt affecting Brahmaputra River levels
- Shifting monsoon patterns
- Increased urban heat island effect in Guwahati
- Expansion of climate-resilient agriculture
Select the correct answer using the code below:
a) 1, 2, and 3 only
b) 2 and 4 only
c) 1 and 4 only
d) 1, 2, 3, and 4
✅ Answer: a) 1, 2, and 3 only
Explanation:
- Glacial melt in the Himalayas increases Brahmaputra’s flood risks.
- Shifting monsoon patterns lead to erratic rainfall, affecting agriculture.
- Urban heat island (UHI) effect in Guwahati worsens heatwaves and energy demand.
- Statement 4 is incorrect: Climate-resilient agriculture reduces vulnerability, not increases it.
Topic 3: Indo-Myanmar Region Hit by 4 Earthquakes in 12 Hours
Question 5
Which of the following tectonic features are responsible for frequent earthquakes in Northeast India?
- Indo-Burmese Subduction Zone
- Sagaing Fault
- Kopili Fault
- Himalayan Thrust Belt
Select the correct answer using the code below:
a) 1 and 2 only
b) 3 and 4 only
c) 1, 2, and 3 only
d) 1, 2, 3, and 4
✅ Answer: d) 1, 2, 3, and 4
Explanation:
- The Indo-Burmese Subduction Zone and Sagaing Fault (Myanmar) are major seismic zones affecting Northeast India.
- The Kopili Fault in Assam is highly active.
- The Himalayan Thrust Belt contributes to earthquakes in Arunachal Pradesh and northern Assam.
Question 6
The Richter Scale and Mercalli Scale are used to measure which aspects of an earthquake?
a) Richter Scale measures intensity, while Mercalli Scale measures magnitude
b) Richter Scale measures magnitude, while Mercalli Scale measures intensity
c) Both measure intensity
d) Both measure magnitude
✅ Answer: b) Richter Scale measures magnitude, while Mercalli Scale measures intensity
Explanation:
- Richter Scale: Measures the magnitude (energy released) of an earthquake.
- Mercalli Scale: Measures the intensity (damage and human perception) of an earthquake.
Topic 4: Life-Support System for Pilots Onboard Tejas Jets Successfully Tested by DRDO
Question 7
The Integrated Life Support System (ILSS) recently tested for the Tejas fighter jet includes which of the following components?
- Onboard Oxygen Generation System (OBOGS)
- Anti-G Strain Suit
- Helmet-Mounted Display System (HMDS)
- Ejection Seat Safety Enhancements
Select the correct answer using the code below:
a) 1 and 2 only
b) 2 and 3 only
c) 1, 2, and 4 only
d) 1, 2, 3, and 4
✅ Answer: c) 1, 2, and 4 only
Explanation:
- ILSS Components:
- OBOGS supplies oxygen without external cylinders.
- Anti-G Strain Suit prevents blackouts due to high G-forces.
- Ejection Seat Safety Enhancements improve pilot survival in emergencies.
- Statement 3 is incorrect: The Helmet-Mounted Display System (HMDS) is part of avionics, not ILSS.
Question 8
Which of the following fighter jets is India’s first indigenous supersonic aircraft?
a) Rafale
b) Sukhoi Su-30MKI
c) Tejas LCA
d) Mirage 2000
✅ Answer: c) Tejas LCA
