Daily Quiz 22 March 2025

Answer: B
Explanation:

● Statements 1 and 2 are correct: Digital twin is a virtual replica of a physical object, person, or process that can be used to simulate its behavior to better understand how it works in real life. Digital twins are linked to real data sources from the environment, which means that the twin updates in real time to reflect the original version. Digital twins also comprise a layer of behavioral insights and visualizations derived from data. When interconnected within one system, digital twins can create a digital and often immersive environment that replicates and connects every aspect of an organization to optimize simulations, scenario planning, and decision making.
● Statement 3 is not correct: Artificial Intelligence (AI)-driven Digital Twins can revolutionize infrastructure planning and design by addressing the challenges in traditional methods like siloed, static, incomplete data and manual interventions. Unlike conventional approaches that rely on fragmented datasets and periodic assessments, AI-driven Digital Twins integrate real-time, cross-sectoral data from various sources in a privacy preserving manner, ensuring a unified and dynamic planning process ensuring integrated planning and fostering a collaborative ecosystem. Digital Twins enable continuous real-time monitoring and predictive analytics. AI enhances data-driven decision making by simulating multiple scenarios, optimizing resource allocation, and improving infrastructure resilience under various conditions.

Answer: D

Explanation:

• Statement 1 is not correct: The Ministry of Education, Department of Higher Education, launched PM-YUVA 3.0 -Prime Minister’s Scheme for Mentoring Young Authors, an Author Mentorship programme to train young and budding authors (below 30 years of age) in order to promote reading, writing and book culture in the country, and project India and Indian writings.

Statement 2 is not correct: A total of 50 authors will be selected through an All India Contest.

Answer: C

Explanation:

• Statements 1 and 2 are correct: Mycelia are the branching filaments of fungi that make up its vegetative part. Researchers have them harnessed to create biodegradable, fire-resistant, and insulative bricks. They are made by combining husk, sawdust, and fungal spores to create a fibrous network that solidifies into a lightweight material. Within a few days, these materials become a hardier structure.

Statement 3 is correct: Mycelium bricks have the potential to reduce the building sector’s carbon footprint, its proponents have said. They are relatively more lightweight and good insulators of heat. Aside from potential use as panelling material in interior designs, researchers believe mycelium-based components can be used in liquid filters, sports equipment, and printed circuit boards.

Answer: C

Explanation:

• Statement 1 is correct: Starlink has over 7,000 satellites in orbit. 2024, the company reported surpassing 4.6 million users worldwide with around 1.4 million subscribers in the US.While Starlink has the largest LEO constellation in the world, Jeff Bezos’s Amazon plans to launch 3,236 satellites with Project Kuiper. Meanwhile, Eutelsat OneWeb currently features more than 630 satellites along 12 synchronised orbital planes. SpaceX also plans to expand its megaconstellation of satellites to 42,000.

Statement 2 is correct: Starlink satellite internet service can work with a different, third-party Wi-Fi router. While the Starlink router that comes with the dish is reportedly sufficiently powerful to provide basic Wi-Fi connectivity, users who are interested in setting up a more sophisticated networking solution can opt for gaming routers or mesh routers in order to expand the network coverage.

Answer: B

Explanation:

• Statement 1 is not correct: On 22nd June 2022, a Brainstorming Workshop was held at the India International Centre, New Delhi, to kickstart the national mission on the National Air Quality Resource Framework of India (NARFI). The workshop was inaugurated by Prof. Ajay Kumar Sood, Principal Scientific Adviser (PSA) to the Government of India, who talked about the complex and multidimensional nature of the pollution problem and emphasised the need for multi-sectoral collaboration among the government, industry, and the citizens, to tackle the challenge. NARFI, developed by the National Institute of Advanced Studies (NIAS) with support from the O/o PSA, is a step in this direction.

Statement 2 is correct: It is a comprehensive guide to collecting air quality data, analyzing the data for an understanding of its impact, and implementing scientific solutions. It is meant to help decision-makers in governments, municipalities, start-ups, and the private sector to address air quality issues in the various climatic zones of our country.
