Q102. Arrange the following steps conceptually involved in deploying an AI model for predictive healthcare in an Indian public hospital:
A. Training the machine learning algorithm on the dataset
B. Collecting anonymized patient electronic health records (EHR)
C. Deploying the model for real-time risk prediction of incoming patients
D. Validating and testing the model for accuracy and bias
A. Training the machine learning algorithm on the dataset
B. Collecting anonymized patient electronic health records (EHR)
C. Deploying the model for real-time risk prediction of incoming patients
D. Validating and testing the model for accuracy and bias
Explanation
Deploying an AI model follows a logical progression starting with data preparation. First, anonymized health records are collected to form a dataset. This data is then used to train the machine learning algorithm. After training, the model must be rigorously validated and tested for accuracy and bias. Finally, once proven reliable, the model is deployed in clinical settings for real-time patient risk prediction.
Q103. Which of the following government initiatives is an exception and is NOT primarily an Artificial Intelligence or Machine Learning based platform?
Explanation
Several government initiatives now incorporate AI, such as Bhashini for translations, Supace for judicial efficiency, and chatbots for citizen assistance. PRAGATI, however, is a multi-modal platform for interactive governance and project monitoring. It primarily uses video conferencing and geospatial technology to track the progress of various infrastructure projects and government schemes, rather than relying on AI-driven automated decision-making or language models.
Q104. What is the cause-and-effect relationship between India’s push for data localization laws and indigenous AI development?
Explanation
Data localization laws require that data generated within India be stored and processed domestically. For AI development, this is crucial because it ensures that high-quality, diverse local data remains available for Indian researchers and companies. Training AI models on local datasets makes them more accurate and culturally relevant for Indian users, particularly for applications in local languages, agriculture, and regional healthcare.
Q105. Identify the odd one out among the tools categorized under India’s Digital Public Infrastructure (DPI) incorporating advanced tech/AI.
Explanation
India’s Digital Public Infrastructure consists of foundational tools like Aadhaar for identity, UPI for payments, and DigiLocker for document storage. These are state-backed platforms designed to provide essential services to all citizens. ChatGPT is a generative AI tool developed by a private foreign company, OpenAI. While it is a popular application, it is not part of India’s indigenous public digital infrastructure.
Q106. Read the following statements and select the correct option:
Assertion (A): The overarching theme of India’s National Strategy for AI is ‘#AIforAll’.
Reason (R): The government intends to leverage AI for inclusive growth, focusing on sectors like agriculture, health, and education.
Assertion (A): The overarching theme of India’s National Strategy for AI is ‘#AIforAll’.
Reason (R): The government intends to leverage AI for inclusive growth, focusing on sectors like agriculture, health, and education.
Explanation
The ‘#AIforAll’ campaign reflects India’s commitment to using artificial intelligence as a tool for inclusive social development.
Q107. The Tejas Mk1A, recently inducted into the Indian Air Force, is categorized as which generation of fighter aircraft?
Explanation
The Tejas Mk1A is classified as a 4.5-generation fighter aircraft. It represents a significant upgrade over the initial version, incorporating modern technologies that bridge the gap between fourth-generation and fifth-generation jets. These enhancements include advanced radar systems, improved electronic warfare capabilities, and the ability to fire sophisticated beyond-visual-range missiles, making it a highly capable platform for the modern battlefield.
Q108. A major upgrade in the Tejas Mk1A is the integration of an AESA radar. What does AESA stand for in this context?
Explanation
AESA stands for Active Electronically Scanned Array, a type of advanced phased-array radar. Unlike traditional radars with moving parts, an AESA radar uses a computer-controlled array of many small transmitter/receiver modules. This allows it to scan the environment faster, track multiple targets simultaneously with higher precision, and be more resistant to electronic jamming, significantly increasing the aircraft’s combat effectiveness and situational awareness.
Q109. The Tejas Light Combat Aircraft (LCA) program is primarily designed and developed by which agency?
Explanation
The Tejas Light Combat Aircraft was designed and developed by the Aeronautical Development Agency, which is the nodal agency for the national combat aircraft program. Operating under the Department of Defence R&D, ADA collaborates with various DRDO laboratories and Hindustan Aeronautics Limited. While HAL is the primary manufacturing partner, the core design and technological development are spearheaded by the specialists at ADA.
Q110. Identify the correct pair regarding the weapon systems integrated on the Tejas Mk1A.
Explanation
The Tejas Mk1A is designed to carry a variety of advanced weapons, including the indigenous Astra missile. Astra is a beyond-visual-range air-to-air missile capable of engaging high-speed aerial targets at long distances. Its integration into the Tejas platform is a major step toward achieving self-reliance in strategic weaponry, reducing the need for imported missiles like those from Russia or Europe.Answer key for these questions

Key facts from Recent Advances, Indian Contributors and Indigenization
- C. V. Raman won the Nobel Prize in Physics in 1930 for the scattering of light; National Science Day on 28 February marks the discovery of the Raman Effect.
- The IGMDP began in 1983; Kalam promoted PURA, the Provision of Urban Amenities to Rural Areas.
- Homi J. Bhabha is the father of the Indian nuclear programme, and his three-stage plan uses PHWRs, fast breeder reactors and thorium reactors.

Frequently asked questions
How many RAS Prelims practice MCQs are there on Recent Advances, Indian Contributors and Indigenization?
This page has 154 practice MCQs on Recent Advances, Indian Contributors and Indigenization (Science and Technology). Each has the correct answer, and most have an explanation.
Why is National Science Day celebrated on 28 February?
To commemorate the discovery of the Raman Effect on 28 February 1928 by C. V. Raman. He won the Nobel Prize in Physics in 1930 for his work on the scattering of light.
What does PURA stand for?
Provision of Urban Amenities to Rural Areas, a concept advocated by Dr A. P. J. Abdul Kalam. It aimed to give villages the roads, connectivity and services of towns so that rural development would be balanced.
Do mRNA vaccines change human DNA?
No. mRNA vaccines do not enter the nucleus of the cell or integrate with the human genome. The cell uses the instruction to make the viral protein and then breaks down the mRNA.
