• Question 3 of 5 3. Question Much of human behaviour is driven not by conscious reasoning but by automatic mental processes. People often believe they make decisions after careful thought, yet research shows that habits, emotions, and cognitive shortcuts shape choices long before awareness intervenes. These unconscious processes are not inherently problematic—without them, daily functioning would be unbearably slow. However, they can also lead to biases, snap judgements, and persistent misconceptions about oneself and others. Becoming psychologically aware requires recognising these mental undercurrents rather than denying them. Awareness does not eliminate biases, but it allows individuals to pause, question assumptions, and choose responses more deliberately. Emotional intelligence, too, is rooted in this skill of noticing inner states before they translate into action. Thus, psychological growth is less about controlling the mind than about understanding its hidden workings. Without this insight, people may remain passengers to their impulses, mistaking automatic reactions for conscious choices. Which one of the following best captures the central message of the passage? (a) Human decisions are entirely irrational and cannot be improved. (b) Psychological growth depends on recognising unconscious influences on behaviour. (c) Emotional intelligence is unrelated to awareness of mental processes. (d) Automatic mental processes should be eliminated for better decision-making. Correct Answer: (b) Explanation: (b) is correct: The passage emphasises understanding unconscious processes as the foundation of psychological awareness and growth. (a) is incorrect: The passage never claims that decisions are entirely irrational. (c) contradicts the passage, which links emotional intelligence to awareness of inner states. (d) is incorrect: The passage says automatic processes are necessary; the goal is awareness, not elimination. Incorrect Answer: (b) Explanation: (b) is correct: The passage emphasises understanding unconscious processes as the foundation of psychological awareness and growth. (a) is incorrect: The passage never claims that decisions are entirely irrational. (c) contradicts the passage, which links emotional intelligence to awareness of inner states. (d) is incorrect: The passage says automatic processes are necessary; the goal is awareness, not elimination.
#### 3. Question
Much of human behaviour is driven not by conscious reasoning but by automatic mental processes. People often believe they make decisions after careful thought, yet research shows that habits, emotions, and cognitive shortcuts shape choices long before awareness intervenes.

• Question 4 of 5 4. Question Consider the following statements: Unconscious mental processes significantly influence human decisions. Awareness of internal emotions and biases allows for more deliberate actions. Automatic thinking should be completely removed to improve psychological functioning. Which of the above statements can be inferred from the passage? (a) 1 and 2 only (b) 1 and 3 only (c) 2 and 3 only (d) All three Correct Answer: (a) Explanation: Statement 1: Supported—automatic processes shape choices “long before awareness intervenes.” Statement 2: Supported—awareness helps individuals “choose responses more deliberately.” Statement 3: Not supported—the passage explicitly says automatic processes are necessary for functioning. Thus, the correct answer is (a). Incorrect Answer: (a) Explanation: Statement 1: Supported—automatic processes shape choices “long before awareness intervenes.” Statement 2: Supported—awareness helps individuals “choose responses more deliberately.” Statement 3: Not supported—the passage explicitly says automatic processes are necessary for functioning. Thus, the correct answer is (a).
#### 4. Question
Consider the following statements:
• Unconscious mental processes significantly influence human decisions.
• Awareness of internal emotions and biases allows for more deliberate actions.
• Automatic thinking should be completely removed to improve psychological functioning.
Which of the above statements can be inferred from the passage?
• (a) 1 and 2 only
• (b) 1 and 3 only
• (c) 2 and 3 only
• (d) All three
Answer: (a)
Explanation:
• Statement 1: Supported—automatic processes shape choices “long before awareness intervenes.”
• Statement 2: Supported—awareness helps individuals “choose responses more deliberately.”
• Statement 3: Not supported—the passage explicitly says automatic processes are necessary for functioning.
Thus, the correct answer is (a).
Answer: (a)
Explanation:
• Statement 1: Supported—automatic processes shape choices “long before awareness intervenes.”
• Statement 2: Supported—awareness helps individuals “choose responses more deliberately.”
• Statement 3: Not supported—the passage explicitly says automatic processes are necessary for functioning.
Thus, the correct answer is (a).
• Question 5 of 5 5. Question Urban transport in India has long struggled with congestion, pollution, and inadequate public mobility options. Rapid motorisation has led to overcrowded roads, declining air quality, and increased travel times, disproportionately affecting low-income commuters who rely on public transport. While cities have attempted solutions such as metro rail expansion, flyovers, and intelligent traffic systems, these interventions often address symptoms rather than structural causes. A sustainable mobility transition requires prioritising public transport, non-motorised travel, and integrated land-use planning. Instead of viewing mobility as merely the movement of vehicles, urban planners must focus on enabling the efficient movement of people. Equally crucial is community participation—transport policies built without understanding commuter needs tend to be underutilised or inequitable. Without a shift toward inclusive and ecological mobility planning, Indian cities risk locking themselves into unsustainable patterns that undermine both liveability and environmental resilience. Which one of the following statements best reflects the most logical and rational message conveyed by the passage? (a) Urban transport challenges in India can be solved primarily through building more flyovers. (b) Sustainable mobility requires people-centric planning and greater reliance on public and non-motorised transport. (c) Motorisation is unavoidable, and Indian cities must adapt to increasing numbers of private vehicles. (d) Metro rail projects alone are sufficient to resolve congestion and pollution issues. Correct Answer: (b) Explanation: Option (b) is correct: The passage emphasises shifting focus from vehicles to people, strengthening public/ non-motorised transport, and integrating land-use planning. Option (a) is incorrect: The passage notes that flyovers treat symptoms, not structural problems. Option (c) is incorrect: The passage argues for sustainable alternatives, not resignation to motorisation. Option (d) is incorrect: It explicitly states that single interventions like metros are insufficient. Hence, (b) captures the core message. Incorrect Answer: (b) Explanation: Option (b) is correct: The passage emphasises shifting focus from vehicles to people, strengthening public/ non-motorised transport, and integrating land-use planning. Option (a) is incorrect: The passage notes that flyovers treat symptoms, not structural problems. Option (c) is incorrect: The passage argues for sustainable alternatives, not resignation to motorisation. Option (d) is incorrect: It explicitly states that single interventions like metros are insufficient. Hence, (b) captures the core message.
