Q1Consider the following statements about Indian space missions: 1. Aditya-L1 is positioned in a halo orbit around the Sun-Earth L1 point, not on the Sun. 2. XPoSat is a dedicated X-ray polarimetry mission rather than an Earth-observation mission. 3. Gaganyaan TV-D1 was India's first crewed spaceflight. Select the correct answer using the code given below.
Statements 1 and 2 are correct. Aditya-L1 observes the Sun from a halo orbit around Sun-Earth L1, and XPoSat studies bright astronomical X-ray sources through polarimetry. TV-D1 demonstrated an in-flight abort and crew-escape-system recovery; it was a test-vehicle flight, not a crewed spaceflight.
Q2With reference to frontier-technology programmes, consider the following statements: 1. The National Quantum Mission covers quantum computing, communication, sensing and metrology, and quantum materials and devices. 2. Doping can alter charge-carrier behaviour in a semiconductor. 3. A chip-design centre and a wafer-fabrication plant perform identical functions. Select the correct answer using the code given below.
Statements 1 and 2 are correct. The National Quantum Mission spans several quantum-technology domains, and semiconductor doping changes charge-carrier behaviour. Chip design and wafer fabrication are distinct layers of the semiconductor ecosystem, so Statement 3 is incorrect.
Q3Match List I with List II and select the correct answer using the code given below. List I (Awarded concept) A. MicroRNA in post-transcriptional gene regulation B. Metal-organic frameworks C. Artificial neural-network foundations for machine learning D. Macroscopic quantum tunnelling and energy quantisation in an electric circuit List II (Award and year) 1. Nobel Prize in Physics, 2025 2. Nobel Prize in Physiology or Medicine, 2024 3. Nobel Prize in Chemistry, 2025 4. Nobel Prize in Physics, 2024
MicroRNA and post-transcriptional gene regulation correspond to the 2024 medicine award; metal-organic frameworks to the 2025 chemistry award; artificial neural-network foundations to the 2024 physics award; and macroscopic quantum tunnelling and energy quantisation in an electric circuit to the 2025 physics award. Therefore option A is correct.
Q4Consider the following statements regarding biotechnology: 1. Gene editing makes targeted changes to DNA sequences. 2. Genome sequencing reads genetic information. 3. A bioreactor helps scale biological production. Select the correct answer using the code given below.
All three statements are correct and describe different parts of biotechnology. Gene editing alters selected DNA sequences, genome sequencing reads genetic information, and bioreactors provide controlled systems for scaling biological production. None of these processes is interchangeable with the others.
Q5Match List I with List II and select the correct answer using the code given below. List I (Institution) A. Department of Science and Technology B. Department of Biotechnology C. ICMR D. IN-SPACe List II (Principal association) 1. Promotion and authorisation of non-government participation in space activities 2. National Quantum Mission 3. Biomedical research and public-health evidence 4. BioE3 Policy
The Department of Science and Technology supports the National Quantum Mission; the Department of Biotechnology handles the BioE3 Policy; ICMR is associated with biomedical research and public-health evidence; and IN-SPACe promotes and authorises non-government participation in space activities. Thus the complete mapping appears in option C.
