Q862. Which two specific components are targeted for financial incentives under the Strategic Interventions for Green Hydrogen Transition (SIGHT) programme?
Explanation
The SIGHT programme specifically targets two critical areas for financial incentives: the domestic manufacturing of electrolysers and the actual production of green hydrogen. These components are essential for building a complete green hydrogen ecosystem within the country. By supporting both manufacturing and production, the government aims to create a self-reliant industry that can meet both domestic and international demand for clean fuel.
Q863. Which industrial sectors are identified as the primary off-takers for initial Green Hydrogen adoption in India to replace fossil fuels?
Explanation
For the initial adoption of green hydrogen in India, the government has identified fertilizer production and petroleum refining as the primary off-taker sectors. These industries currently use large amounts of hydrogen produced from fossil fuels. Replacing this with green hydrogen will lead to a significant reduction in industrial carbon emissions and help create a stable market for the emerging green hydrogen economy.
Q864. Consider the following outcomes expected by 2030 from the National Green Hydrogen Mission:
I. Creation of over 6 lakh jobs.
II. Abatement of nearly 50 MMT of annual greenhouse gas emissions.
III. Complete cessation of all fossil fuel imports.
Which of the above statement(s) is/are correct?
I. Creation of over 6 lakh jobs.
II. Abatement of nearly 50 MMT of annual greenhouse gas emissions.
III. Complete cessation of all fossil fuel imports.
Which of the above statement(s) is/are correct?
Explanation
By 2030, the National Green Hydrogen Mission is expected to create over six lakh jobs and lead to a significant abatement of annual greenhouse gas emissions. While the mission aims to reduce the reliance on fossil fuel imports, it does not expect a complete cessation of all such imports within this timeframe. The focus remains on strategic decarbonization and building a sustainable energy future.
Q865. The India Semiconductor Mission (ISM) operates as an independent business division within which entity?
Explanation
The India Semiconductor Mission functions as an independent business division within the Digital India Corporation. This arrangement provides the mission with the necessary autonomy and flexibility to manage the complex tasks of promoting the semiconductor ecosystem. By operating under the Ministry of Electronics and Information Technology, the mission can effectively coordinate various incentive schemes and international collaborations for chip manufacturing.
Q866. Under the modified scheme for setting up Semiconductor Fabs in India, what percentage of the project cost is offered as fiscal support by the Central Government on a pari-passu basis?
Explanation
Under the modified semiconductor schemes, the central government offers fifty percent fiscal support for setting up semiconductor fabrication units in India. This support is provided on a pari-passu basis, meaning the government contributes alongside the private investors during the project’s development. This high level of financial assistance is designed to make India an attractive destination for global semiconductor manufacturing giants.
Q867. The acronym OSAT, commonly used in the semiconductor industry and targeted by the India Semiconductor Mission, stands for:
Explanation
OSAT stands for Outsourced Semiconductor Assembly and Test, a critical phase in the semiconductor supply chain. This process involves the final packaging and testing of semiconductor devices after they have been fabricated on wafers. The India Semiconductor Mission provides specific incentives to promote the establishment of OSAT facilities in India, as they are essential for creating a complete and localized semiconductor manufacturing ecosystem.
Q868. Arrange the following stages of semiconductor manufacturing in the correct logical sequence:
I. Assembly, Testing, Marking, and Packaging (ATMP)
II. Wafer Fabrication
III. Integrated Circuit (IC) Design
I. Assembly, Testing, Marking, and Packaging (ATMP)
II. Wafer Fabrication
III. Integrated Circuit (IC) Design
Explanation
Semiconductor manufacturing follows a specific logical sequence. It begins with the Integrated Circuit design phase, where the chip’s architecture is planned. This is followed by Wafer Fabrication, a complex process of creating the physical circuits on silicon wafers. Finally, the chips undergo Assembly, Testing, Marking, and Packaging to prepare them for integration into various electronic devices and consumer products.
Q869. What is the purpose of the Design Linked Incentive (DLI) scheme under the India Semiconductor Mission?
Explanation
The Design Linked Incentive scheme is a key part of the India Semiconductor Mission that focuses on the chip design ecosystem.
Q870. Identify the exception. The India Semiconductor Mission provides fiscal support for setting up facilities in all of the following domains EXCEPT:
Explanation
The India Semiconductor Mission focuses specifically on high-tech domains like silicon CMOS fabs, display fabs, and compound semiconductors. It does not provide fiscal support for traditional industrial activities like internal combustion engine assembly lines. The mission’s incentives are strictly targeted toward building the advanced technological infrastructure required for a modern semiconductor industry and reducing India’s heavy reliance on electronic imports.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.
