• Question 1 of 5 1. Question Indian classical dance forms are not merely aesthetic performances but repositories of cultural memory. Rooted in ancient texts like the Natya Shastra, they combine movement, music, and storytelling to convey spiritual and social narratives. Over centuries, Bharatanatyam, Kathak, Odissi, and other forms adapted to changing patronage—from temples to royal courts to modern stages—while retaining their symbolic vocabulary of gestures and expressions. Yet, urbanization and commercialization have led to concerns of dilution, as performances are sometimes reduced to entertainment devoid of spiritual depth. Advocates argue that safeguarding these traditions requires not only institutional support and training but also community-level participation to ensure continuity across generations. Preserving authenticity while encouraging innovation remains the central challenge for India’s cultural heritage in a globalized world. Which of the following statements can be logically inferred from the passage? Indian classical dance forms are evolving cultural traditions rather than static practices. The transition from temples to modern stages has altered the context but not the essence of these dance forms. Commercialization poses a risk of reducing classical dance to mere entertainment. Innovation should be discouraged to maintain the authenticity of traditional art forms. Select the correct answer using the code given below: (a) 1, 2 and 3 only (b) 2, 3 and 4 only (c) 1 and 4 only (d) 1, 2, 3 and 4 Correct Answer: (a) Explanation: Statement 1 is correct — the passage emphasizes historical adaptation to changing contexts. Statement 2 is correct — the movement from temples to courts to modern stages illustrates change in venue but continuity in symbolic vocabulary. Statement 3 is correct — commercialization and loss of spiritual depth are explicitly mentioned. Statement 4 is incorrect — the passage stresses balancing authenticity with innovation, not discouraging it. Hence, option (a) is correct. Incorrect Answer: (a) Explanation: Statement 1 is correct — the passage emphasizes historical adaptation to changing contexts. Statement 2 is correct — the movement from temples to courts to modern stages illustrates change in venue but continuity in symbolic vocabulary. Statement 3 is correct — commercialization and loss of spiritual depth are explicitly mentioned. Statement 4 is incorrect — the passage stresses balancing authenticity with innovation, not discouraging it. Hence, option (a) is correct.

• Question 2 of 5 2. Question Based on the passage, consider the following assumptions: Cultural preservation requires both institutional efforts and grassroots involvement. Globalization automatically strengthens traditional art forms by providing them a wider audience. Which of the above assumptions is/are valid? (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2 Correct Answer: (a) Explanation: Assumption 1 is valid — the passage explicitly notes that institutional support and community participation are necessary for safeguarding traditions. Assumption 2 is invalid — globalization is described as a context where balancing authenticity and innovation is a challenge, not an automatic strengthening. Therefore, only assumption 1 is valid. Correct answer is (a). Incorrect Answer: (a) Explanation: Assumption 1 is valid — the passage explicitly notes that institutional support and community participation are necessary for safeguarding traditions. Assumption 2 is invalid — globalization is described as a context where balancing authenticity and innovation is a challenge, not an automatic strengthening. Therefore, only assumption 1 is valid. Correct answer is (a).

• Question 3 of 5 3. Question Indian cities are increasingly experiencing the urban heat island effect, where dense built-up areas record significantly higher temperatures than surrounding rural zones. Factors such as loss of tree cover, proliferation of concrete surfaces, and rising vehicular emissions contribute to this phenomenon. Heat islands worsen energy demand for cooling, increase health risks during heatwaves, and degrade overall urban livability. While initiatives like rooftop gardens, reflective building materials, and urban forestry are being piloted, their impact is uneven due to limited scale and poor enforcement of urban planning norms. Experts argue that mitigating heat islands requires integrating climate-sensitive design into building codes, expanding green spaces, and ensuring coordination between municipal bodies and citizens. Without comprehensive adaptation, heat-related stresses could intensify urban inequality and strain public health systems. Which of the following statements best reflects the most logical and rational inference/inferences that can be made from the passage? Urban heat islands are primarily caused by natural climatic variations. Coordinated urban planning and citizen participation are essential to mitigate rising heat stresses. Select the correct answer using the code given below: (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2 Correct Solution: (b) Explanation: Statement 1 is incorrect — the passage attributes heat islands to human-driven causes like concrete surfaces, tree loss, and emissions, not just natural variation. Statement 2 is correct — it highlights that effective mitigation requires climate-sensitive design, municipal coordination, and community involvement. Hence, the correct answer is (b). Incorrect Solution: (b) Explanation: Statement 1 is incorrect — the passage attributes heat islands to human-driven causes like concrete surfaces, tree loss, and emissions, not just natural variation. Statement 2 is correct — it highlights that effective mitigation requires climate-sensitive design, municipal coordination, and community involvement. Hence, the correct answer is (b).

Solution: (b)

• Question 4 of 5 4. Question Based on the above passage, the following assumptions have been made: Technological measures like rooftop gardens and reflective materials must be supported by proper regulation and scaling to be effective. Increasing energy demand due to heat islands has little impact on public health. Select the correct answer using the code given below: (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2 Correct Solution: (a) Explanation: Assumption 1 is valid — the passage notes such technologies exist but are ineffective without scale and enforcement, implying regulation is key. Assumption 2 is invalid — it clearly links heat islands to health risks and stress on public health systems, so their impact is significant. Thus, only assumption 1 is valid, making (a) correct. Incorrect Solution: (a) Explanation: Assumption 1 is valid — the passage notes such technologies exist but are ineffective without scale and enforcement, implying regulation is key. Assumption 2 is invalid — it clearly links heat islands to health risks and stress on public health systems, so their impact is significant. Thus, only assumption 1 is valid, making (a) correct.

• Question 5 of 5 5. Question A machine depreciates at the rate of 20 percent annually. If its value in 2021 was Rs 51,200, what was its value 2 years before? (a) Rs 80,000 (b) Rs 75,000 (c) Rs 85,000 (d) Can’t be determined Correct Answer: (a) Solution The value of a machine is depreciating by 20 percent every year. We know that A = P [1 – (R/100)]t. Here, A = 51,200; R = 20; t = 2. So, 51,200 = P (80/100)2 Or 51,200 = P (16/25) Or P = 51,200 × 25 / 16 Or P = Rs 80,000 So, price of the machine 2 years ago was Rs 80,000. Hence, option (a) is the right answer. Incorrect Answer: (a) Solution The value of a machine is depreciating by 20 percent every year. We know that A = P [1 – (R/100)]t. Here, A = 51,200; R = 20; t = 2. So, 51,200 = P (80/100)2 Or 51,200 = P (16/25) Or P = 51,200 × 25 / 16 Or P = Rs 80,000 So, price of the machine 2 years ago was Rs 80,000. Hence, option (a) is the right answer.
