Explanation
One Nation, One Subscription under STIP 2020 aims to solve the high cost of journal subscriptions for Indian researchers by giving them access through a single national subscription.Explanation
The National Quantum Mission is an initiative of the Department of Science and Technology. The other pairs are mismatched.Assertion (A): The Green Hydrogen Mission relies heavily on the expansion of India’s renewable energy capacity.
Reason (R): Green hydrogen is produced by the electrolysis of water, a process that must be powered by renewable energy sources to be classified as ‘green’.
Explanation
The Green Hydrogen Mission relies on expanding renewable energy capacity because green hydrogen is made by electrolysis of water powered by renewable energy. R explains A.Explanation
DigiLocker is the digital document wallet under Digital India where citizens can store and access authentic documents and certificates.Explanation
In the BioE3 policy, E3 stands for Economy, Environment and Employment.Explanation
The PM-WANI scheme is a Digital India initiative designed to expand internet access through a vast network of public Wi-Fi hotspots. It allows small shopkeepers and local providers to offer Wi-Fi services to the public, creating a decentralized and affordable way for citizens to stay connected. By increasing the availability of public Wi-Fi, the scheme aims to promote digital inclusion and support the growing knowledge economy.Explanation
The Atmanirbhar Bharat Abhiyan does not ban foreign direct investment; on the contrary, it includes several reforms to attract more FDI, especially in sectors like defense. The campaign focuses on making India self-reliant by strengthening domestic industries and simplifying regulations. It aims to build a strong internal economy that is globally integrated and resilient to external shocks, rather than adopting a policy of economic isolation.| Institution | Focus Area |
|---|---|
| A. SERB | i. Supercomputing and advanced IT |
| B. NIF | ii. Funding basic scientific research |
| C. CDAC | iii. Grassroots technological innovations |
| D. AIM | iv. Innovation and entrepreneurship ecosystem |
Explanation
India’s innovation ecosystem is supported by various institutions with distinct focus areas. The Science and Engineering Research Board funds basic scientific research, while the National Innovation Foundation supports grassroots technological innovations. CDAC is the premier organization for supercomputing and advanced IT, and the Atal Innovation Mission is dedicated to creating a vibrant ecosystem for innovation and entrepreneurship throughout the entire country.Explanation
Quantum sensing is a key focus of the National Quantum Mission, with practical applications in the development of highly accurate atomic clocks. These quantum-based clocks are essential for precise navigation systems, as they provide timing accuracy far beyond that of traditional technologies. Such sensors are critical for the next generation of satellite-based positioning and other strategic applications requiring extreme measurement precision and stability.Answer key for these questions

Key facts from Science and Technology
- The RPSC paper is General Knowledge and General Science, so science questions come with a strong dose of applied and recent topics.
- Everyday science questions test the laws and terms of physics, chemistry and biology through examples.
- Defence and space questions pair a missile, satellite or mission with its year and organisation.
- Policy questions ask for the year, the body and the aim of schemes like STIP, the National Quantum Mission and BioE3.
- Health, environment and agriculture are on a separate page, with their own chapters.
Frequently asked questions
How many RAS Prelims practice MCQs are there on Science and Technology?
This page has 1113 practice MCQs on Science and Technology. Each has the correct answer, and most have an explanation.
Which chapters does the science and technology set cover?
Six chapters: basics of everyday science; computers, information and communication technology; defence and space technology in India; genetics, biotechnology and nanotechnology; science and technology policies and government programmes; and recent advances, Indian contributors and indigenisation.
Is science and technology part of the RAS Prelims syllabus?
Yes. The RPSC paper is called General Knowledge and General Science, and its syllabus lists science and technology topics along with environment, health, agriculture and government programmes, so questions can come from any of these areas.
How should I prepare science for RAS Prelims?
Revise the concepts by examples, then learn the missions, schemes and scientists with their year and organisation. Attempt each chapter, read the explanations and keep a list of the facts you missed.
