Q871. Given below are two statements regarding semiconductors. Statement I: Compound semiconductors (like Gallium Nitride and Silicon Carbide) are critical for high-power and high-frequency applications, such as electric vehicles and 5G. Statement II: The India Semiconductor Mission does not provide any incentives for compound semiconductor facilities. In light of the above statements, choose the correct answer from the options given below:
Explanation
Compound semiconductors are indeed essential for modern applications like 5G and electric vehicles due to their high efficiency. Contrary to the second statement, the India Semiconductor Mission provides significant incentives for setting up compound semiconductor facilities. The government recognizes the strategic importance of these materials and offers fiscal support to ensure that India develops a strong manufacturing base in this advanced technological field.

Q873. Which of the following best defines the concept of ‘Circular Bioeconomy’ emphasized in the BioE3 Policy?
Explanation
A circular bioeconomy involves the sustainable use of renewable biological resources to produce food, materials, and energy. The core principle is to minimize waste by keeping resources in use for as long as possible and recycling biological materials back into the production cycle. This approach reduces the reliance on fossil-based products and helps mitigate the environmental impact of industrial manufacturing processes.

Q874. Which key global challenge does the BioE3 policy directly seek to mitigate through its push for biomanufacturing?
Explanation
The BioE3 policy is specifically designed to address global challenges such as climate change and the depletion of natural resources. By promoting biomanufacturing and bio-based products, the policy seeks to provide sustainable alternatives to traditional chemical processes that contribute to environmental degradation. This shift is essential for achieving long-term ecological balance and ensuring the sustainable availability of resources for future generations.

Q875. The BioE3 policy focuses on shifting the manufacturing paradigm from:
Explanation
One of the fundamental shifts proposed by the BioE3 policy is moving the manufacturing paradigm from traditional chemical-based processes to modern bio-based ones. This transition utilizes biological systems like microorganisms and enzymes to produce chemicals, materials, and fuels. Bio-based manufacturing is generally more sustainable and environmentally friendly, as it often requires less energy and generates fewer harmful by-products compared to conventional chemical industries.

Q877. Which new institutional structures are proposed under the BioE3 Policy to bridge the gap between research and commercial scale-up?
Explanation
To bridge the gap between initial research and large-scale commercial production, the BioE3 Policy proposes the creation of Biomanufacturing Hubs and Biofoundries. These facilities will provide the necessary infrastructure and expertise for startups and industries to scale up their biotechnological innovations. By centralizing high-end equipment and technical support, these hubs will accelerate the development and market entry of bio-based products.

Q878. Which of the following is an odd one out regarding the strategic themes of the BioE3 Policy?
Explanation
The strategic themes of the BioE3 Policy include climate-resilient agriculture, high-value bio-based chemicals, and smart proteins. Deep-sea mineral mining is not a part of this policy, as it falls under different ocean exploration initiatives. The BioE3 Policy focuses specifically on utilizing biological systems and biotechnology to solve economic and environmental challenges through sustainable biomanufacturing and circular economy principles.

Q879. What is the fundamental rationale for establishing Bio-AI hubs under the BioE3 Policy?
Explanation
Bio-AI hubs are established under the BioE3 Policy to integrate artificial intelligence with biotechnological research. The fundamental rationale is to use AI and machine learning to analyze complex biological data and optimize manufacturing processes. This integration can lead to faster discovery of new bio-products, improved efficiency in production, and more precise control over biological systems, ultimately driving innovation in the bioeconomy.

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
