Q1:
With reference to deepfake technology, consider the following statements: 1. Deepfakes are generated primarily using machine learning techniques such as Generative Adversarial Networks (GANs). 2. Deepfakes can be used only for visual manipulation (images and videos) and cannot be applied to audio content. Which of the statements given above is/are correct?
A: 1 only
B: 2 only
C: Both 1 and 2
D: None
Answer: A
Explanation:
Statement 1 is correct.
Deepfakes are generated using advanced machine learning models, especially Generative Adversarial Networks (GANs), where one neural network generates fake content and another evaluates it for authenticity.
Statement 2 is incorrect.
Deepfakes are not limited to visuals. They also involve audio manipulations, including voice cloning and synthetic speech, which can recreate a person’s voice convincingly.
Q2:
In the context of challenges posed by deepfake technology, which of the following are potential risks for democratic and social processes? 1. Manipulation of political speeches to spread misinformation during elections. 2. Financial fraud through impersonation of individuals using synthetic voice technology. Select the correct answer using the code below:
A: 1 only
B: 2 only
C: Both 1 and 2
D: None
Answer: C
Explanation:
Statement 1 is correct.
Deepfakes can fabricate political speeches, interviews, or statements, influencing public opinion and interfering with electoral processes—posing a serious challenge to democratic integrity.
Statement 2 is correct.
Voice cloning and video manipulation can enable impersonation of executives, government officials, or family members, leading to financial fraud, cyber-scams, or phishing attacks.
Q3:
With reference to India’s commitment to achieving Net-Zero emissions, consider the following statements: 1. India has committed to achieving net-zero greenhouse gas emissions by 2070, as announced at COP26 in Glasgow. 2. India aims to meet at least 50% of its total energy requirements from renewable energy sources by 2030. 3. India has pledged to reduce its carbon intensity by 45% by 2030 relative to 2005 levels. Which of the statements given above is/are correct?
A: 1 and 2 only
B: 1 and 3 only
C: 2 and 3 only
D: 1, 2, and 3
Answer: D
Explanation:
Statement 1 is correct.
At COP26 (Glasgow, 2021), India announced its target to achieve net-zero emissions by 2070, forming part of the Panchamrit commitments.
Statement 2 is correct.
India aims to fulfill 50% of its energy requirements from renewable energy by 2030, which includes solar, wind, hydro, and nuclear.
Statement 3 is correct.
India has committed to reducing carbon intensity by 45% by 2030 compared to 2005 levels—another major climate pledge.
Q4:
Consider the following environmental initiatives and policies of India: 1. National Hydrogen Energy Mission — aims to scale up green hydrogen production and promote hydrogen valleys. 2. 2G Ethanol Programme — supports advanced biofuels by converting agricultural waste into ethanol. 3. National Clean Air Programme (NCAP) — targets a 40% reduction in particulate pollution by 2035. Which of the statements given above is/are correct?
A: 1 and 2 only
B: 1 and 3 only
C: 2 and 3 only
D: 1, 2, and 3
Answer: A
Explanation:
Statement 1 is correct.
The National Hydrogen Energy Mission promotes green hydrogen, electrolyser manufacturing, and hydrogen valleys, supporting India’s long-term decarbonization strategy.
Statement 2 is correct.
The 2G Ethanol programme focuses on second-generation biofuels, using agricultural residues (like rice straw) to produce ethanol—reducing stubble-burning and fossil-fuel dependence.
Statement 3 is incorrect.
Under NCAP, the target is to reduce PM2.5 and PM10 levels by 20–30% by 2024 (later extended to 2026), not 40% by 2035.
Q5:
With reference to emerging technologies, consider the following statements: 1. Quantum computing relies on qubits, which can exist in multiple states simultaneously due to superposition. 2. Blockchain technology eliminates the need for any consensus mechanism due to its decentralized nature. 3. Edge computing reduces latency by processing data closer to the source rather than relying on centralized cloud servers. Which of the statements given above is/are correct?
A: 1 and 2 only
B: 1 and 3 only
C: 2 and 3 only
D: 1, 2, and 3
Answer: B
Explanation:
Statement 1 is correct.
Quantum computing uses qubits, which can be in a state of 0, 1, or both simultaneously (superposition), enabling exponentially faster computing for certain tasks.
Statement 2 is incorrect.
Blockchain does require consensus mechanisms, such as Proof-of-Work (PoW) or Proof-of-Stake (PoS), to verify transactions and maintain trust in decentralized systems.
Statement 3 is correct.
Edge computing processes data closer to the “edge” (devices, sensors), thereby reducing latency, bandwidth use, and dependence on centralized cloud infrastructure.
