Explanation
The Geosynchronous Satellite Launch Vehicle Mark III is India’s most powerful launch vehicle, capable of carrying heavy payloads into orbit. It played a critical role in major lunar exploration missions, including Chandrayaan-2 and Chandrayaan-3. ISRO has officially renamed this heavy-lift rocket as LVM3 to reflect its mission capabilities more accurately as a versatile launch system for various orbital requirements.Explanation
The Department of Space in India has a unique administrative structure designed to ensure direct executive oversight. It reports directly to the Prime Minister, rather than being part of the Ministry of Science and Technology. The Space Commission provides policy guidance, while ISRO serves as the research arm. This arrangement facilitates rapid decision-making and strategic planning for the country’s space programme.I. He was the founding director of the Tata Institute of Fundamental Research (TIFR).
II. He served as the first Chairman of the Atomic Energy Commission of India.
III. He was awarded the Nobel Prize in Physics for his work on the cosmic ray cascade process.
Which of the above statement(s) is/are correct?
Explanation
Homi J. Bhabha was a central figure in Indian science, founding the Tata Institute of Fundamental Research and serving as the first Chairman of the Atomic Energy Commission. While his theoretical work in physics was internationally acclaimed and led to nominations, he did not receive the Nobel Prize. His legacy primarily lies in institutionalizing scientific research and pioneering the atomic energy programme.Statement I: The Software Technology Parks of India (STPI) provided single-window clearance and tax incentives to IT companies in the 1990s.
Statement II: Tata Consultancy Services (TCS) was one of the earliest Indian IT companies to pioneer the global delivery model for software services.
Identify the correct statement from the options below.
Explanation
The growth of India’s IT industry was driven by both government support and private enterprise. The Software Technology Parks of India provided essential infrastructure and tax benefits during the 1990s. Simultaneously, companies like Tata Consultancy Services were pioneers in developing the global delivery model. These combined efforts allowed the sector to provide high-quality software services to international clients efficiently.Assertion (A) and the other as Reason (R):
Assertion (A): The initial phase of the Green Revolution in India led to widening regional economic disparities.
Reason (R): The high-yielding variety technologies were primarily successful in regions with assured irrigation infrastructure, such as Punjab, Haryana, and western Uttar Pradesh. In the context of the above statements, which one of the following is correct?
Explanation
The initial phase of the Green Revolution significantly boosted food production but also created regional economic disparities. This occurred because high-yielding variety seeds required reliable irrigation and chemical inputs, which were more readily available in states like Punjab, Haryana, and western Uttar Pradesh. Consequently, these regions prospered while areas lacking similar infrastructure did not experience the same level of agricultural growth.I. The tests were conducted over three days in May 1998.
II. The operation involved the testing of a thermonuclear device.
III. Following the successful tests, India immediately signed the Comprehensive Nuclear-Test-Ban Treaty (CTBT).
IV. The date of the first test, May 11, was officially declared as National Technology Day in India.
Which of the above statement(s) is/are correct?
Explanation
The Pokhran-II tests in May 1998 involved multiple detonations, including a thermonuclear device, over several days. Following these successful tests, the government declared May 11 as National Technology Day to celebrate scientific achievement. Crucially, India did not sign the Comprehensive Nuclear-Test-Ban Treaty afterward, maintaining its strategic autonomy and refusing to accept what it considered discriminatory international nuclear non-proliferation regimes.Explanation
The Indian Institute of Science in Bangalore saw a major transformation in its aerospace and atmospheric research capabilities after independence. This expansion occurred significantly under the leadership of Satish Dhawan, who served as the Institute’s director. His dual role as the head of ISRO and IISc helped integrate academic research with the practical requirements of the burgeoning national space programmes.Explanation
India’s biotechnology sector is home to several major indigenous firms specializing in vaccine production. Companies like the Serum Institute of India and Bharat Biotech have achieved global recognition for their manufacturing capacity and development of domestic vaccines. While Pfizer has a significant presence in India, it is a multinational corporation headquartered in the United States, not an indigenous Indian pharmaceutical company.| Supercomputer Series | Developing Organization |
|---|---|
| A. PARAM series | i. Bhabha Atomic Research Centre (BARC) |
| B. Anupam series | ii. National Aerospace Laboratories (NAL) |
| C. PACE series | iii. Defence Research and Development Organisation (DRDO) |
| D. Flosolver | iv. Centre for Development of Advanced Computing (C-DAC) |
Explanation
Different Indian organizations developed supercomputers to meet specialized needs. C-DAC produced the PARAM series for general-purpose high-performance computing. The Bhabha Atomic Research Centre developed the Anupam series for nuclear research. DRDO created the PACE series for defense and aerodynamic simulations, while the National Aerospace Laboratories built the Flosolver specifically to solve complex fluid dynamics problems relevant to aviation and meteorological studies.Answer key for these questions

Frequently asked questions
How many RAS Prelims practice MCQs are there on Science and Technology in Independent India?
This page has 68 practice MCQs on Science and Technology in Independent India (Modern Indian History). Each has the correct answer, and most have an explanation.
What is the three-stage nuclear power programme?
The plan devised by Homi J. Bhabha to use India’s limited uranium and large thorium reserves in three stages: natural uranium reactors, fast breeder reactors and, finally, thorium-based reactors. It remains the basis of India’s nuclear energy policy.
Which rocket launched Aryabhata?
A Soviet Kosmos-3M rocket, in April 1975. Aryabhata was India’s first satellite, built by ISRO, and it was launched from the Soviet Union because India had no launch vehicle of that capability at the time.
What is the IGMDP?
The Integrated Guided Missile Development Programme, launched in 1983 under DRDO with Dr A. P. J. Abdul Kalam as its chief architect. It developed missiles such as Prithvi, Agni, Trishul, Akash and Nag.
